Why is Science Important?. Yesterday, I had a Q&A session with… | by Avi Loeb | Dec, 2022 | Mediumhttps://avi-loeb.medium.com/why-is-science-important-416fc081a8edThe challenges of adapting to new environments in space would be vast, far greater than the challenge of leaving the jungles of Africa to inhabit tech-rich cities — which our predecessors accomplished in the span of the last hundred thousand years. Survival of the fittest in interstellar space requires the tools of advanced science and technology.
For long-term survival, we must figure out how to repair and augment the human body so that our future astronauts will have a lifetime of millions of years in interstellar space. This would lead to an exponential growth in the population of interstellar spacecraft. The doubling time could be as short as 100,000 years, the travel time of our existing chemical rockets to the habitable planets around the nearest star to the Sun, Proxima Centauri. Over merely 5 million years, the lifespan of the human species so far, interstellar astronauts could go through 40 doublings. Starting with a single craft might yield 2 to the power of 40 spacecraft in 5 million years. This amounts to a trillion spacecraft which could target all the habitable planets in the Milky Way galaxy.
Sharing our scientific knowledge with all intelligent beings in interstellar space could be a natural extension of our international scientific endeavor on Earth. Expanding the scientific program from international to interstellar also offers a grander benefit from reciprocity. One of our destinations might include a civilization which made scientific discoveries that exceed our knowledge. In that case, we could learn from them.
Here’s hoping that the friction that interstellar explorers will encounter with nay-sayers or bureaucrats who want them to focus all resources on their home planet, might be overcome by the fruits of interstellar wisdom. Ad Astra!
