The Reality of the Big Bang

In reality, we know very little about the universe. We depend on a non-physical entity to give you some kind of insight into all that's non-physical. I posted yesterday on social media one famous scientist talking about how now we are really revisiting the whole concept of the Big Bang. And it takes billions of years for every galaxy to form. Now with better telescopes, we're starting to observe galaxies that are bigger than ours,. that are half a billion years from the Big Bang - that appeared half a billionyears from the Big bang.
