| Aug 8, 2020 at 22:36 | comment | added | Jubbles | Apologies in advance for my naïveté, but isn't "observable universe" a concept that depends on the existence of Earth at a specific time? If so, how can a statement be made about the observable universe during a time (since the big bang) when the Earth did not yet exist? | |
