What is Fermi’s question?
If technologically advanced civilisations are actually widespread, considering distances and even if every star in our galaxy has a single Earth sized planet, the represented proportions would indicate that civilisations should be widespread. Why have they not detected us?
Which part of the Drake equation will we have a number for in 10 years?
How many planets in a star system could host life
What is the copernican principle?
We are not unique or special
What are the potential answers for Fermi’s question?
- Rare Earth Hypothesis is correct
- The lifetime of civilisations never overlap
- We missed them as they deemed Earth uninhabitable
- Hiding themselves from us intentionally or unintentionally
- The universe is simply too large
What is the best way for us to communicate with other civilisations?
Radio waves
What is the waterhole?
1.4-1.6Hz is a quiet window which means we can monitor if another civilisations sends a signal
When was the WOW signal?
