Introduction
Understanding the Evolution of Civilizations through the Kardashev Scale
The search for extraterrestrial intelligence, the quest to understand our place in the cosmos, and the drive to push the boundaries of human potential have long fascinated scientists and visionaries alike. As we peer into the vastness of the universe, we are compelled to ask: How advanced could civilizations in the universe become? How might our own civilization evolve in the coming millennia? These profound questions led to the development of the Kardashev Scale, a visionary framework that categorizes civilizations based on their energy consumption—a fundamental measure of technological progress and potential.
A Visionary Framework for Measuring Civilizational Progress
The Kardashev Scale offers more than just a theoretical construct; it is a window into the future of technological advancement, societal evolution, and our potential role as cosmic citizens. By classifying civilizations from planetary to universal levels, the scale provides a structured way to think about the steps humanity might take to achieve greater mastery over energy, space, and time. It challenges us to consider the vast possibilities that lie ahead, as well as the ethical, social, and environmental implications of our choices.
The Spectrum of Civilizations from Type I to Type V
The Kardashev Scale traditionally categorizes civilizations into three types: Type I (Planetary Civilization), which can harness all the energy available on its home planet; Type II (Stellar Civilization), capable of using the total energy output of its star; and Type III (Galactic Civilization), which controls energy on the scale of an entire galaxy. Over time, this concept has been expanded to include speculative Type IV (Universal Civilization), which could harness energy across an entire universe, and Type V (Multiversal Civilization), which might operate across multiple universes. Each of these levels represents a monumental leap in technological prowess, social complexity, and ethical responsibility.
As we delve into each of these categories, we will explore not only the theoretical underpinnings of the Kardashev Scale but also its practical implications for humanity’s future. How close are we to becoming a Type I civilization? What challenges must we overcome to ascend to higher levels? What are the risks and responsibilities associated with such power? These are the questions that will guide our exploration.

Section 1: Origins and Purpose of the Kardashev Scale
1.1 The Origin of the Kardashev Scale
Background on Nikolai Kardashev and His Motivations
The Kardashev Scale was introduced by the Russian astrophysicist Nikolai Kardashev in 1964, a time when humanity was just beginning to explore the possibilities of space travel and the potential for extraterrestrial life. Kardashev, born in Moscow in 1932, was deeply influenced by the burgeoning field of radio astronomy, which had opened up new ways of studying the universe. His work focused on the search for signals from advanced civilizations beyond Earth, a field that would later become known as the Search for Extraterrestrial Intelligence (SETI).
Kardashev’s interest in the possibility of advanced civilizations was not purely speculative. He was motivated by the idea that the universe, with its billions of stars and planets, might host civilizations far more advanced than our own. He recognized that the primary marker of such advancement would likely be the ability to harness and control energy on a scale far beyond what humanity had achieved. This led him to propose a framework for categorizing civilizations based on their energy consumption—a concept that would become known as the Kardashev Scale.
The Scientific Context of the Time: SETI and the Quest to Understand Advanced Civilizations
The 1960s were a period of intense scientific curiosity about the cosmos, fueled by rapid advancements in technology and a growing understanding of the universe’s vastness. The launch of the first artificial satellite, Sputnik, in 1957, and the subsequent space race between the United States and the Soviet Union, brought space exploration to the forefront of global consciousness. This era also saw the development of radio telescopes, which allowed scientists to listen for signals from distant stars and galaxies.
Amid this excitement, the question of whether humanity was alone in the universe became more pressing. SETI emerged as a serious scientific endeavor, with researchers using radio telescopes to search for artificial signals that might indicate the presence of intelligent extraterrestrial life. Kardashev was particularly interested in the types of civilizations that might exist and how they could be detected. He reasoned that a civilization’s ability to communicate across the vast distances of space would depend on its energy consumption, leading him to propose a scale that measured civilizations by this very metric.
The Kardashev Scale was thus born out of a unique intersection of astrophysics, technology, and the philosophical quest to understand our place in the cosmos. It provided a structured way to think about civilizations that might be much older and more technologically advanced than humanity.
1.2 The Purpose of the Kardashev Scale
Classifying and Envisioning the Technological Capabilities of Potential Extraterrestrial Civilizations
The primary purpose of the Kardashev Scale is to offer a means of classifying civilizations based on their ability to harness energy. Kardashev identified three initial types of civilizations:
- Type I Civilization: A civilization that can utilize all the energy available on its home planet.
- Type II Civilization: A civilization capable of harnessing the total energy output of its star.
- Type III Civilization: A civilization that can control energy on the scale of its entire galaxy.
These categories provide a framework for envisioning the possible levels of technological advancement that a civilization could achieve. By focusing on energy consumption as a metric, the scale avoids assumptions about the specific technologies a civilization might use, instead emphasizing the broader capability to control and utilize energy on different scales. This makes the Kardashev Scale a versatile tool for thinking about a wide range of potential civilizations, regardless of their specific technological paths.
Reflecting the Relationship Between Energy Consumption and Technological Advancement
The Kardashev Scale reflects a fundamental relationship between energy consumption and technological advancement. As a civilization progresses, its demand for energy increases. This is true for humanity, as we have moved from burning wood and coal to harnessing nuclear power and exploring renewable energy sources. In Kardashev’s view, the ability to harness greater amounts of energy is a key indicator of a civilization’s technological maturity.
- Type I Civilization represents mastery over the resources of a single planet. It implies a high level of technological development, including the ability to control climate, prevent natural disasters, and manage resources sustainably.
- Type II Civilization suggests a civilization that has expanded its reach beyond its home planet to control and use the energy of its star. This would involve advanced space travel, possibly colonization of other planets, and the construction of megastructures like a Dyson Sphere.
- Type III Civilization would be capable of harnessing energy across an entire galaxy, implying technologies far beyond our current understanding, such as energy extraction from black holes or the manipulation of dark matter.
The scale also implicitly raises questions about the social, ethical, and environmental implications of such advancements. For example, the transition to a Type I civilization might require global cooperation on an unprecedented scale, while the leap to Type II could involve ethical dilemmas related to the manipulation of entire star systems.
By linking energy consumption to technological progress, the Kardashev Scale provides a lens through which we can examine not only potential extraterrestrial civilizations but also our own trajectory as a species. It challenges us to consider the long-term future of humanity, the possibilities for technological advancement, and the responsibilities that come with increased power and capability.

2.2 Type II Civilization (Stellar Civilization)
A Type II Civilization on the Kardashev Scale represents a society that has mastered the ability to harness the total energy output of its star. This monumental leap in technological prowess would allow such a civilization to utilize energy on a scale that far surpasses anything currently imaginable on Earth. The concept of a Type II civilization opens the door to extraordinary advancements, including megastructures that capture stellar energy, space colonization, and the ability to manipulate entire planetary systems.
Energy Sources and Usage
Introduction to Megastructures like Dyson Spheres
At the heart of a Type II civilization’s energy strategy is the concept of megastructures designed to capture the energy output of a star. The most famous of these is the Dyson Sphere, a hypothetical structure first proposed by physicist Freeman Dyson in 1960. A Dyson Sphere would completely encompass a star, capturing nearly all of its energy output for use by the civilization.
While the classic Dyson Sphere is often imagined as a solid shell surrounding a star, more practical designs suggest a swarm of satellites—sometimes called a Dyson Swarm—orbiting the star and collecting energy. These satellites would beam the energy back to planets or space habitats, providing an almost limitless supply of power.
Potential Technologies: Advanced Solar Power and Space-Based Energy Harvesting
To construct and maintain such megastructures, a Type II civilization would need to develop advanced technologies far beyond our current capabilities. Some of these might include:
- Advanced Solar Power: Technologies that maximize the efficiency of solar energy collection would be essential. This could include materials with near-perfect photovoltaic efficiency, self-repairing surfaces, and adaptive optics that can track and focus sunlight more effectively than anything available today.
- Space-Based Energy Harvesting: Beyond the Dyson Sphere concept, a Type II civilization might develop other forms of space-based energy harvesting. For example, they could deploy vast arrays of solar collectors in space to gather energy directly from their star and transmit it wirelessly to planetary surfaces or space stations using microwave or laser beams.
- Star Lifting: Another speculative technology is star lifting, which involves extracting matter from a star to use as a resource. This process could be used to extend the star’s lifespan or to control its energy output more precisely.
Technological and Social Implications
Impact of Stellar Energy Control on Space Colonization and Human Expansion
The ability to control and utilize stellar energy would revolutionize space colonization and interplanetary travel. With vast amounts of energy at their disposal, a Type II civilization could:
- Power Interplanetary Travel: The energy harnessed from a star could be used to power spacecraft capable of traveling across the solar system—or even to other star systems. These spacecraft might use advanced propulsion systems, such as photon sails or fusion drives, which require enormous amounts of energy.
- Space Colonization: With energy no longer a limiting factor, a Type II civilization could establish colonies on planets, moons, and even artificial habitats throughout its star system. These colonies would be fully self-sustaining, relying on beamed energy from the Dyson Swarm or other space-based sources.
- Terraforming: Stellar energy could be used to terraform planets, making them suitable for human habitation. This might involve altering a planet’s atmosphere, temperature, and surface conditions to mimic Earth-like environments, thereby expanding the civilization’s living space.
Altering Orbits, Terraforming Worlds, and Controlling a Star’s Lifecycle
A Type II civilization would have the technological capability to manipulate entire planetary systems. This could include:
- Altering Planetary Orbits: Using advanced propulsion systems, a Type II civilization might move planets within its star system to optimize conditions for life or resource extraction. For example, they could shift a planet closer to the star to warm it or move it farther away to cool it down.
- Terraforming: Beyond basic terraforming, a Type II civilization could undertake more ambitious projects, such as creating entirely new planets or moons, or even constructing artificial worlds from raw materials. They might also modify existing planets to support specific ecosystems or industries.
- Controlling a Star’s Lifecycle: With mastery over stellar energy, a Type II civilization could potentially influence the lifecycle of their star. This might involve prolonging its life by carefully managing its fuel consumption or even triggering controlled stellar events to generate specific types of energy.
Challenges and Ethical Considerations
Ethical Questions About Manipulating Star Systems
The immense power and technological capability of a Type II civilization would raise profound ethical questions:
- Impact on Other Life Forms: Manipulating star systems could have unintended consequences for other forms of life, both within the civilization’s own system and potentially in nearby systems. For example, altering a star’s output could affect the habitability of planets or moons that support life, raising ethical concerns about the right to interfere with natural ecosystems.
- Exploitation of Resources: The extraction of energy and matter from a star or planets could lead to ethical dilemmas regarding the sustainability and long-term impacts of such activities. A Type II civilization would need to consider the balance between resource use and conservation, ensuring that their actions do not deplete or destabilize the very systems they rely on.
- Cultural and Philosophical Impacts: The ability to manipulate planets, stars, and entire systems would challenge fundamental philosophical and cultural beliefs about the nature of life, existence, and humanity’s place in the universe. It might lead to debates about the morality of playing such an active role in shaping the cosmos.
Potential Impacts on Other Life Forms
The potential to inadvertently harm or even destroy other life forms is a significant ethical concern. A Type II civilization might encounter primitive life forms or even other intelligent species during their expansion. The ethical questions would be complex:
- Non-Interference vs. Utilitarianism: Should a Type II civilization adopt a policy of non-interference, respecting the natural development of other life forms, or should they prioritize their own survival and expansion, even if it means altering or destroying other ecosystems?
- Protection of Emerging Civilizations: If a Type II civilization encounters a developing civilization at an earlier stage on the Kardashev Scale, ethical considerations would include whether to protect, assist, or leave them undisturbed. The potential for unintended harm would be high, requiring careful deliberation.
The transition to a Type II civilization would mark a turning point in the history of any species, representing a level of technological mastery and energy control that allows for unprecedented expansion and manipulation of their environment. However, with great power comes great responsibility, and the ethical implications of such advancements must be carefully considered to avoid unintended consequences and ensure that the benefits of such progress are shared equitably and sustainably.
2.3 Type III Civilization (Galactic Civilization)
A Type III Civilization on the Kardashev Scale represents the pinnacle of energy harnessing and technological mastery, capable of utilizing the entire energy output of a galaxy. This level of civilization would have the ability to manipulate and control celestial phenomena on a galactic scale, with implications that extend far beyond anything humanity can currently envision. The challenges, opportunities, and ethical considerations of such a civilization are profound, reshaping our understanding of what is possible in the universe.
Energy Sources and Usage
Harnessing Energy Across an Entire Galaxy
A Type III civilization would not be limited to a single star or planetary system. Instead, it would draw energy from a wide array of cosmic sources, including some of the most powerful and exotic phenomena in the universe:
- Black Holes: One of the most potent energy sources available in a galaxy is a black hole, particularly supermassive black holes found at the centers of galaxies. A Type III civilization could potentially extract energy from the rotational energy of a black hole through processes like the Penrose process or Hawking radiation. Additionally, they might harness the immense gravitational forces and relativistic jets emitted by these celestial giants.
- Neutron Stars and Pulsars: Neutron stars, particularly pulsars, emit intense beams of radiation and have extremely strong magnetic fields. A Type III civilization might tap into these energy emissions or even manipulate the star’s magnetic field to generate power.
- Stellar Harvesting: Beyond individual stars, a Type III civilization could create networks of Dyson Spheres or similar structures around multiple stars across the galaxy, capturing their energy output on an unprecedented scale.
- Dark Matter and Dark Energy: While still theoretical, the manipulation of dark matter or dark energy could provide an additional, possibly limitless, source of power. These mysterious substances make up most of the universe’s mass-energy content, and a Type III civilization might unlock the secrets to using them as energy sources.
Speculative Technologies for Galactic-Scale Energy Management
To manage and distribute energy across an entire galaxy, a Type III civilization would need technologies that are almost unimaginable by today’s standards. Some possibilities include:
- Galaxy-Scale Networks: A vast network of energy collectors, storage units, and transmission lines could span the entire galaxy, allowing energy to be harvested from any location and distributed where needed. This network might utilize quantum entanglement or wormholes to facilitate instant energy transfer across light-years of distance.
- Energy Beaming Across Vast Distances: Similar to the concept of space-based solar power, but on a galactic scale, this technology would involve beaming energy across the galaxy using high-powered lasers or other forms of directed energy. This would require an intricate understanding of the space-time fabric to minimize energy loss over vast distances.
- Stellar and Planetary Engineering: A Type III civilization could engineer stars and planets to optimize their energy output or even create new energy sources. For instance, they might induce supernovae under controlled conditions to harvest the resulting energy.
Technological and Social Implications
Galaxy-Wide Colonization and Its Impact on Society
With the ability to harness and control galactic energy, a Type III civilization could embark on galaxy-wide colonization, leading to a civilization that spans billions of star systems. The implications of such expansion are staggering:
- Interstellar Travel and Communication: Efficient and fast interstellar travel would be essential for colonizing distant star systems. Technologies like warp drives, wormholes, or other forms of faster-than-light travel might become realities for a Type III civilization. Communication across such vast distances could involve advanced quantum communication networks or even the manipulation of space-time itself to send information instantaneously.
- Societal and Political Structures: Governing a civilization that spans an entire galaxy would require unprecedented levels of organization and coherence. Traditional concepts of nation-states or planetary governments might give way to a more unified, galaxy-wide governance structure. This might involve autonomous AI-driven systems, decentralized networks, or a highly evolved form of democratic governance that includes representatives from countless star systems.
- Cultural Evolution: The cultural implications of living in a galactic civilization would be profound. Cultures would evolve to reflect the diversity and scale of the galaxy, potentially leading to a fusion of ideas, languages, and beliefs on an unprecedented scale. The concept of identity might shift from being planet-based to a broader galactic perspective.
Maintaining Coherence and Governance Across Vast Distances
One of the key challenges for a Type III civilization would be maintaining coherence and effective governance across the vast distances of the galaxy:
- Centralized vs. Decentralized Governance: A Type III civilization might opt for a decentralized model of governance, where each star system or cluster of systems operates autonomously but within a unified framework. Alternatively, there could be a centralized authority, possibly an AI or collective intelligence, that manages galaxy-wide affairs.
- Information and Resource Management: Managing information, resources, and population across billions of star systems would require advanced AI and quantum computing systems capable of processing and analyzing data on an unimaginable scale. These systems would ensure that resources are allocated efficiently, that laws and regulations are enforced, and that all parts of the galaxy are connected.
Challenges and Ethical Considerations
Moral Implications of Galactic-Scale Engineering
As a Type III civilization manipulates entire galaxies, it must confront significant ethical challenges:
- Impact on Galactic Ecology: Just as we consider the environmental impact of our actions on Earth, a Type III civilization would need to consider the effects of its actions on the galaxy’s natural balance. This includes the potential disruption of star systems, the alteration of planetary orbits, and the consequences of harvesting energy from black holes or other celestial bodies.
- Responsibility to Other Life Forms: In a galaxy teeming with potentially billions of life forms, a Type III civilization must grapple with the moral implications of its actions on other intelligent and non-intelligent species. This could include the ethical dilemmas of colonizing planets already inhabited by other life forms or the decision to alter star systems that are critical to the development of emerging civilizations.
- Self-Destruction Risks: The immense power and advanced technologies at the disposal of a Type III civilization could pose risks of self-destruction, either through unintended consequences of galactic engineering or through internal conflicts over resource allocation or governance.
Possible Effects on the Galaxy’s Natural Balance
The manipulation of energy on a galactic scale could have far-reaching consequences for the galaxy’s natural state:
- Stellar and Planetary Stability: Altering the energy output of stars, moving planets, or creating artificial celestial bodies could destabilize local star systems, potentially leading to the collapse of stars or the destruction of planets.
- Galactic Climate: Just as Earth has a climate, so too might a galaxy have a form of “climate” that could be disrupted by large-scale engineering projects. This could include changes in the distribution of dust, gas, and other materials that affect star formation and the overall dynamics of the galaxy.
- Long-Term Sustainability: A Type III civilization must consider the long-term sustainability of its actions. Extracting energy from the galaxy without consideration for replenishing or maintaining the balance could lead to resource depletion or catastrophic changes in the galaxy’s structure.
Type III civilization represents the ultimate expression of technological and energy mastery, capable of controlling and utilizing the vast resources of an entire galaxy. However, the challenges of maintaining coherence across such vast distances, the ethical implications of galactic-scale engineering, and the potential risks of disrupting the natural balance of the galaxy underscore the immense responsibility that comes with such power. As we imagine the future of civilizations on this scale, we must also consider the profound ethical and philosophical questions that arise with the ability to shape the cosmos itself.
2.4 Proposed Extensions: Type IV and Type V Civilizations
As we expand the Kardashev Scale beyond its original scope, we delve into the realms of pure speculation and theoretical physics. The concepts of Type IV and Type V Civilizations extend the scale from harnessing the energy of a galaxy to controlling the energy and resources of an entire universe or even multiple universes. These speculative extensions push the boundaries of what we can conceive in terms of technology, power, and responsibility.
Type IV Civilization (Universal Civilization)
A Type IV Civilization would be capable of harnessing and manipulating the energy of an entire universe. This would include not just the energy from stars, galaxies, and black holes, but also more elusive and mysterious forms of energy such as dark energy and the fundamental forces that govern the universe.
Speculative Discussion on Harnessing Universal Energy
At this level, a civilization would have the ability to tap into the very fabric of the universe itself. This could involve:
- Dark Energy: Dark energy is thought to make up about 68% of the universe’s total energy density, driving its accelerated expansion. A Type IV civilization might find ways to harness this energy for various purposes, such as powering enormous projects or stabilizing their own existence against universal decay.
- Manipulation of Cosmic Forces: Beyond just harvesting energy, a Type IV civilization could control fundamental forces like gravity and electromagnetism. This might allow them to manipulate space-time on a universal scale, perhaps even controlling the expansion of the universe or redirecting entire galaxies.
Potential Technologies: Universe-Scale Engineering
To harness and control the energy of an entire universe, a Type IV civilization would need technologies that transcend our current understanding:
- Universe-Scale Engineering: This could involve creating structures or networks that span the entire universe, capable of drawing on its vast energy resources. For example, a civilization might construct a Cosmic Web—a network of structures embedded in the dark matter filaments that connect galaxies, allowing for the efficient transfer of energy and information across the universe.
- Control Over Fundamental Forces: Technologies that could manipulate the basic forces of nature would be essential. This might include devices that can alter gravitational fields, generate or nullify electromagnetic forces, or even control the strong and weak nuclear forces. Such control would enable feats like stabilizing black holes, preventing supernovae, or even initiating new Big Bangs.
Philosophical Implications: Control on a Universal Scale
The ability to exert control over an entire universe raises profound philosophical questions:
- What is the Purpose?: If a civilization can control a universe, what would be their ultimate goal? Would they strive to maintain the universe as it is, reshape it to their liking, or perhaps even create new universes? These questions challenge our understanding of purpose and meaning on a cosmic scale.
- The Nature of Godhood: A Type IV civilization might possess powers traditionally attributed to deities, such as creation, destruction, and omnipresence. This blurs the line between advanced technology and what might be considered divine, raising questions about the nature of godhood and the potential for a civilization to transcend its own existence.
Ethical Considerations: Universe-Altering Consequences
The ethical implications of such immense power are staggering:
- Interference with Natural Processes: By controlling the universe’s fundamental forces, a Type IV civilization could interfere with natural processes on a massive scale. This raises questions about the rights of other life forms or civilizations that might exist within the universe. Should a Type IV civilization have the right to alter or end the universe for their own purposes?
- Potential for Catastrophic Mistakes: The power to control a universe comes with the risk of catastrophic errors. A single miscalculation could lead to the collapse of the universe, the creation of dangerous anomalies, or the unintended destruction of life on a cosmic scale.
Type V Civilization (Multiversal Civilization)
A Type V Civilization takes the Kardashev Scale to its ultimate extension, imagining a society that exists across multiple universes within a multiverse. This civilization would have the capability to traverse, manipulate, and perhaps even create universes, operating on a level that challenges the very concepts of space, time, and reality.
Speculations on Multiversal Civilizations
In a multiverse scenario, a Type V civilization might:
- Traverse Multiple Universes: They could develop technologies that allow for travel between different universes, accessing the unique resources, energies, and conditions that each universe provides. This could involve manipulating the quantum fabric of reality or using advanced forms of wormholes that connect different universes.
- Manipulate Spacetime on a Multiversal Scale: A Type V civilization might not only travel between universes but also alter the structure of spacetime within and between them. This could involve creating new universes, merging or splitting existing ones, or controlling the birth and death of universes.
Theoretical Energy Sources and Technologies
To operate across multiple universes, a Type V civilization would require technologies and energy sources far beyond our current understanding:
- Multiverse Travel: The ability to move between universes would require a deep understanding of quantum mechanics, string theory, or other advanced theories that describe the multiverse. Technologies might include quantum gateways or brane manipulation devices that allow for safe and controlled transitions between universes.
- Manipulation of the Multiverse: Beyond just traveling, a Type V civilization could manipulate the multiverse itself. This might involve altering the physical constants of a universe, creating entirely new universes with specific properties, or even controlling the interactions between different universes.
Omnipotence and Its Implications for Intelligence and Consciousness
At this level of power, the concept of omnipotence—complete and unlimited power—becomes relevant. A Type V civilization might achieve a form of omnipotence, raising questions about:
- The Nature of Intelligence: What does it mean to be intelligent when you can control multiple universes? Intelligence at this level might involve not just solving problems or creating technologies but fundamentally understanding and shaping the fabric of reality itself.
- Consciousness and Existence: The consciousness of beings in a Type V civilization might extend beyond individual bodies or even single universes. Such beings could exist simultaneously in multiple universes, with a collective consciousness that spans the multiverse. This challenges our understanding of what it means to be a conscious, sentient being.
Ethical and Existential Questions
The ethical and existential implications of a Type V civilization are perhaps the most profound of all:
- Responsibility for the Multiverse: If a Type V civilization can create, destroy, or manipulate universes, what responsibilities do they have to the multiverse as a whole? Should they act as custodians, preserving the balance of the multiverse, or are they free to reshape it according to their will?
- The Nature of Existence: If a Type V civilization can create new universes, what does this say about the nature of existence? Are the universes they create as real as the one they originated from? What rights do the inhabitants of these created universes have, if any?
- Moral Relativism on a Multiversal Scale: With the power to control multiple universes, a Type V civilization might develop a form of moral relativism, where actions are judged based on their impact across the multiverse rather than within a single universe. This could lead to ethical frameworks that are incomprehensible to lower-level civilizations.
The concepts of Type IV and Type V civilizations extend the Kardashev Scale into realms of pure speculation, where the lines between science, philosophy, and theology blur. These hypothetical civilizations challenge our understanding of energy, power, intelligence, and ethics, raising questions about the ultimate potential of sentient beings and the nature of reality itself. While these ideas may seem far-fetched, they provide a fascinating framework for exploring the possibilities of advanced civilizations and the future of intelligent life in the universe and beyond.
Section 3: Humanity’s Place on the Kardashev Scale
