Nov 1, 2017 fun fact: for every grain of sand on every beach on earth, there are 100 earth-like planets in the universe. that's: 1,000,000,000,000,000,000,000 earth-like planets.
Nov 1, 2017 I lean towards yes but then sometimes I think how perfect everything came together for earth and maybe we are the only one. I read an article last week suggesting how there is a critical period when a a new planet is formed that life needs to establish before the atmosphere becomes too hostile- they mention how if life did evolve in other parts of the universe , its probably mostly extinct by now.
Nov 1, 2017 2 things 1. and 2. We know life only can form on conditions like earth, because we have earth to document.
Nov 1, 2017 well... we know life can form on conditions like earth, but we don't know that life can ONLY form on conditions like earth. which means that this could be a farrrrrrr underestimate, since intelligent life could also potentially form on non-earth-like planets (which would absolutely dwarf this number):
Nov 1, 2017 this is the best article on the fermi paradox and it doesn't require you to know jack s--- about space or math or aliens or how to wipe your a--- to be able to understand: https://waitbutwhy.com/2014/05/fermi-paradox.html
Nov 2, 2017 how??? you would need to actually know exact probability of life evolving for this. The sample size is 1 after all.
Nov 2, 2017 20% of all stars have habitable planets orbiting them...and there are (a lot) more stars in the universe than grains of sand on Earth I also read somewhere that the odds of us being the only technologically advanced civilisation in our galaxy - let alone the universe - is 1 in 60 billion So yeah, we ain’t the only b------s up in here
