Morgan Freeman's wormhole is a much better program regarding the study of the universe.
yeah, probably. but this was the first episode so they may have just started with the "basic" stuff.
My brain literally can't fathom how big the "multiverse" could really be.
yeah, no matter how many times i see something showing it, i still get the weird, anxious feeling in my feet when someone shows it again. If you think the stuff they showed about the size/length of time and space is amazing, wait until they (hopefully) get into the stuff that shows how the two interact with each other. and how wrong our perception of each is.
