My twitter: https://twitter.com/Dreksler_Astral Cosmic distances are a lot bigger than they may seem, and light has to cross that path in order for us to see stars and everything.

Sizes of the telescopes calculated trough the help of this article: http://www.askamathematician.com/2013/04/q-what-kind-of-telescope-would-be-needed-to-see-a-person-on-a-planet-in-a-different-solar-system/ Footage gathered trough a space simulation: Space Engine.
