A question that bothered me a lot when I was younger, and it bothered me even more when I found out about Olber's Paradox. Here's my take.

Music used:

  • just imagine if big bang was just an experiment of an other alien race or something beyond our imagination.

  • Anyone know what this song is?

  • amoralis123, in science, a fact is something which is assumed to be true until it can be disproved.

  • Big Bang is a conjecture. Eyes receptors of Microwaves? What nonsense in the name of science.

    The sky is dark at night because it is filled with Dark Matter, still under research. Please do not make Science a Religion. Science deals with facts. A Theory when proven becomes a Fact.

    Please tell only what is Factual as a Fact. Thanks

    A good video. Keep on. Ignorant humans need to be enlightened, lest they fall prey to Religion. Save them.

    Of course, I am a non believer.

  • @realchris1Returns It's the galactic disk. We can't see through interstellar dust in visible light.

  • Thanks. Your postings are really excellent and informative..

  • Just a quick question, if you pause at 4:44 what is that large dark "rip" that goes across the universe? It kinda looks like a giant equator.

  • If you look at the right lower corner of the screen at around 5:10 you can see an evil alien face, these are the gods of the universe!

  • Does that look flat to you?

  • THX tony ....yoUR VIDEOS ROCK
