What are Some Things Humans Assume About Aliens?

The realm of aliens and their hypothetical societies often thrives on popular assumptions and speculative science fiction. However, by delving into the actual scientific principles at play, we can disentangle some of these assumptions and approach the topic with a clearer, more grounded perspective.

Assumptions About Alien Technology

It is commonly assumed that an extra-terrestrial society would share similar technological limitations and goals with humanity. This logic is based on the idea that they would have to follow the same natural laws. Once they become space faring, their technology should evolve similarly to ours. They would need to create artificial mobile biospheres—inter-planetary vessels that mimic their home environment—to ensure their survival during space travel.

False Notions About Alien Life

Several misconceptions about alien life persist in our collective imagination. Many envision silicon-based life due to its structural similarity to carbon. However, silicon is significantly heavier and does not form long chains like carbon. Additionally, silicon cannot create gas equivalents to carbon dioxide, which carbon-based life uses for carbon uptake. This makes silicon-based life exceedingly simple and rare, necessitating a planet with light gravity and abundant liquid silicon. Silicon-based life is, thus, impossible.

The Reality of Technological Parity

Another prevalent assumption is that alien life has surpassed us in technology, making it difficult or impossible for us to detect or communicate with them. However, considering the uniqueness of our solar system and the age of the universe, it is unlikely that alien life would be significantly more advanced. The early universe and the formation of stars and heavy elements has influenced the timeline of life emergence, indicating that alien life forms would likely be slightly more or less advanced than us. The universe evolves at the same pace everywhere.

The Speed of Light Conundrum

Perhaps the most intriguing factor in the search for extraterrestrial life and communication is the speed of light. If we were to find a way to convert matter into negative mass, we could potentially surpass the speed of light. However, the energy required to achieve this is beyond our current technological or scientific means. This makes it a significant limitation in our ability to communicate with potential alien life. Similarly, the light we receive from distant galaxies tells us about their past, not their present, due to the vast distances involved.

In Search of New Horizons

Techniques such as gravitational lensing may hold the key to overcoming these limitations. By using gravitational lensing, we might develop a faster-than-light method of observation. If a series of gravitational lenses aligns with a particular galaxy, it could provide us with valuable insights into that galaxy without the interference of the light travel time. This technology could revolutionize our understanding of the universe and aid in our quest to communicate with potential alien life.

While these advancements remain in the realm of speculation, the exploration of space and the search for life elsewhere in the universe continue to push the boundaries of human knowledge and technology. Understanding the true nature of alien life involves not only scientific inquiry but also a willingness to challenge our most cherished assumptions.

Conclusion

The search for extraterrestrial life is a complex and multifaceted endeavor. By reframing our assumptions about alien life and technology, and by embracing the challenges and opportunities presented by scientific advancements, we may one day discover not only the existence of alien life but also the means to communicate with it.
