WebWe don't know that time started at the big bang, that's conjecture. The quote about the North Pole was from Hawking, but there is no evidence to support it, it was pure conjecture without theoretical underpinning. We know that the universe at the big bang was very low entropy, but there's nothing to say that time started then. WebThe big bang theory was thought up almost 100 years ago. And scientists and the public have accepted it as the origin of the universe for over 50 years. Yet it still holds many mysteries. Most of these revolve around the fact that what we see doesn’t match what theory tells us. If we go by the evidence, ~95% of the universe is invisible.

Many cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere.
WebAug 21, 2006 · Once upon a time, 14 billion years ago, a cosmic explosion released an immense amount of heat and pressure. All the particles and energy in our universe, once confined to a space about the size of a dime, raced away from one another at tremendous speeds. As the hot particles cooled and continued to expand into space, matter formed … WebAfter the Big Bang, the universe was like a hot soup of particles (i.e. protons, neutrons, and electrons). When the universe started cooling, the protons and neutrons began combining into ionized atoms of hydrogen (and eventually some helium). These ionized atoms of hydrogen and helium attracted electrons, turning them into neutral atoms - which allowed …
