What was the universe before Big Bang?
What are some alternate theories to the singularity existing at t=0 just before the Big Bang? What else could have existed just before the Big Bang?
What happened after the Big Bang? What is happening on the other side of the singularity (*Big Bang)? Did the Big Bang actually occur? What happened at the time of the Big Bang? What logical processes lead scientists to conclude that the origin of the universe was the Big Bang? Were all the universes in Multiverse theory created at the Big Bang? What happened in the first second of the big bang? Is the Big Bang really the the origin of our universe? Where did the big bang take place? What happened on the first second of the big bang? Why didn't the universe collapse into a black hole just seconds after the Big Bang? I imagine it was very dense at that moment. How did the Big Bang actually happen? What happened at the first second of the beginning of the universe? The first moment of big bang? What will happen if Big Bang occurred once again? Where did the energy from the big bang/singularity come from? What is the flaw in the Big Bang Theory? What is the origin of the universe? Does the big bang theory really explain it? Assuming that the Big Bang is a white hole, then won't it become impossible to find out what happened between the singularity and the event horizon? How can time begin at the Big Bang? Did God create the Big Bang? If we accept the Big Bang Theory as correct, what does this imply about the possibility of something like that occurring again? Scientist say Big Bang is the start of the whole Universe, is it true? Because I dont really think Big Bang is the start of everything Since energy was the only thing existing at the big bang initial point, did it create or cause all of the universe? If the beginning of the universe followed laws of thermodynamics, must have required time and time started only after big bang. So how do they fit in? Since energy was the only thing existing at the big bang initial point, did it create/cause all of the universe? What is an explanation of the Big Bang theory? What is a simple explanation of the Big Bang theory? Why is the Big bang theory wrong? What proof is needed? What is the proof for big bang theory in simple words? Where is the origin point of the big bang in space? And how far are we from there?
