The Big Bang theory states that approximately 14 billion years ago the universe burst into being from an unknown cosmic trigger. The early universe, contained within just a few millimeters, was very hot and densely packed with matter. Ever since that initial explosion, the universe has continued to expand and cool.

Although generally accepted as the model for the origin and evolution of the universe, the Big Bang theory is not complete. For example, it does not explain what caused the initial expansion or why galaxies formed. However, there is significant evidence that the universe did originate from such an event. Three key pieces of observational evidence lend support to the Big Bang theory: the measured abundances of elements, the observed expansion of space, and the discovery of the cosmic microwave background (CMB).

  • @Gandalf54231 Where did "God" come from? Who knows, but adding "God" into the equation only further complicates what we don't know...lets figure out what we have evidence for first, instead of praying to air.

  • @Gandalf54231 That is not yet known.

    However, just because we don't know something YET doesn't allow for us to put a god label on it.

  • i enjoyed this vid

  • really informative and interesting

  • @freedomofthought100 elaborate, how do philosophers prove spirits, ghosts or gods?

  • @freedomofthought100 if you think theology and philosophy can scientifically prove something, I am not going to argue with you any further. I thank you too.

  • @onlyforytb

    the point is your mathematics cannot prove ghost, spirit, god, past and future events etc. but many lay people, theosophist,philosophers prove them. and this proves that mathematics HAS LIMITATION. thank you.
