Intertemporal Communication
Cool Worlds・2 minutes read
Humanity's search for alien life is driven by our social nature and fear of loneliness, with the possibility of being alone in the galaxy leading to a reevaluation of our place in the universe and the potential for communication through time capsules made from durable materials like tungsten or graphene to preserve our knowledge for billions of years.
Insights
- The rarity of intelligent life in the galaxy may suggest humanity is alone, altering our cosmic perspective significantly.
- Various materials like tungsten, osmium, graphene, and diamond offer better long-term preservation for messages on the moon, potentially lasting billions of years, prompting innovative ideas for transmitting knowledge across the cosmos.

Recent questions
Why are humans driven to search for alien life?
Humans are motivated by their social nature and fear of loneliness to seek out alien life. The desire to connect with other beings and expand our understanding of the universe pushes us to explore the possibility of life beyond Earth. This innate curiosity and need for companionship drive our relentless search for extraterrestrial civilizations, despite the challenges and uncertainties involved.
What is the Drake Equation used for?
The Drake Equation is utilized to estimate the number of communicative civilizations in the galaxy. By considering various factors such as the rate of star formation, the fraction of stars with planets, and the likelihood of planets capable of supporting life, this equation provides a framework for predicting the potential existence of intelligent life forms that could communicate with us. It serves as a tool for scientists to quantify the probability of encountering alien civilizations in our galaxy.
How does Einstein's theory of a block universe relate to communication with past civilizations?
Einstein's theory of a block universe, which posits that time is an illusion and all moments in time exist simultaneously, opens up the possibility of communication with past civilizations. This concept suggests that past, present, and future events are fixed and coexist, allowing for the potential transmission of messages or knowledge to civilizations that existed in the past. By understanding time as a static construct, we may find ways to bridge temporal gaps and interact with ancient societies through innovative means.
What materials offer better resistance to erosion for long-term preservation on the moon?
Denser materials like tungsten, osmium, graphene, and diamond provide superior resistance to erosion compared to aluminum, making them ideal for long-term preservation on the moon. These robust materials can withstand the harsh lunar environment and potential impacts from micro meteorites, ensuring the longevity of time capsules or artifacts left for future civilizations to discover. By utilizing these durable substances, we can enhance the chances of preserving our knowledge and messages for billions of years on the moon's surface.
How can knowledge be dispersed across the galaxy for potential discovery by other civilizations?
To disseminate knowledge across the galaxy for potential discovery by other civilizations, innovative methods such as launching fleets of miniaturized probes or constructing thin sheets in orbit of stars can be employed. By utilizing advanced technology and strategic placement of information-carrying devices, we can increase the likelihood of our messages reaching distant civilizations. Initiatives like the Voyager Golden Record, made of stable gold, and the concept of deploying numerous probes aim to transcend the limitations of space and time, allowing for the transmission of valuable insights and cultural artifacts to alien beings in the cosmos.

"Preserving Apollo footprints with durable materials"
- Footprints left by Apollo astronauts on the moon are not a long-lasting preservation method due to erosion, estimated to disappear in 1-2 million years, while equipment like lunar descent modules, although more promising, will eventually break down from micro meteorite impacts.
- Denser materials like tungsten and osmium, or carbon derivatives such as graphene and diamond, offer better resistance to erosion than the aluminum used in Apollo equipment, potentially lasting for billions of years on the moon's surface.
- Suggestions for long-term preservation include burying denser time capsules under lunar regolith, using materials like conformer clad tungsten carbide, or constructing thin sheets in orbit of stars to transmit messages across the cosmos.
- Voyager Golden Record, made of stable gold, may last for at least a billion years in deep space, but its small size makes it imperceptible unless near another civilization's telescopes, prompting the idea of launching fleets of miniaturized probes to disperse knowledge across the galaxy.
