The Big Bang theory is not old, but it is widely accepted amongst physicists all over the world. Not everything is easy to explain, though. The uneven distribution of matter and the existence of life are two examples of issues which scientists will have to explain in order to finally prove the theory. A central question in the Big Bang theory is whether the universe is expanding or not. Another problem is the conservation of energy. We have selected some websites which offer insight into these matters.
