Although we still have several open questions, decades of observations and theoretical modelling have allowed us to reconstruct the past of our Universe. But what will our Universe look like way after the Earth and the Sun will cease to exist, and may intelligent life still develop in the far future?
A correction from Dr Sorini: ‘When mentioning brown dwarfs in the second last slide, I said that they are low-mass stars that can reach very long life spans. This is actually what a “red dwarf” is. Instead, brown dwarfs are not stars. They are objects with a mass between the most massive gas giant planets and the least massive stars, and cannot trigger nuclear fusion of hydrogen into helium. Thus, brown dwarfs can be considered “failed stars”.’
