Yes even the big bang requires faith that the observable expansion of the universe has been expanding since the big bang and will always continue to do so. We do not know whether there is some kind of force field or whatever out there that the furthermost objects in this part of the universe (assuming there could be even more 'universes' out there) will and/or do eventually reach and then reverse and go the opposite or a different direction.
The big bang is the most plausible theory that science has come up with for what science is a capable of observing at this time. But it is a theory, not a fact, and does require faith to believe it is the ONLY possible way things could be what we observe.
Wrong fox, and you know it is wrong. No one anywhere ever stated that the big bang was the ONLY option. It is just the best one that we currently have. That requires ZERO faith. Period. You are trying to force the way you see things, with faith, on others that do not share that trait. Please stop, it is annoying.
Again the Big Bang is NOT an explanation for the origins of the Universe. It is only the most popular theory for why things behave the way they are currently behaving.
I think the author of the OP had a much larger vision than that when he started the thread. He can correct me if I am wrong about that.
Quite the contrary, the big bang is the explanation for the beginning of the universe. That is the center of the theory. Before the big bang happened, as the theory goes, the universe and all the physical laws that it follows did not exist. Therefore it is the beginning. Anything before that is rather meaningless as time did not necessarily exist ‘before’ the big bang though there are some theories that are based in string theory that try and define what made up the material that the big bang started with. Those, however, are far beyond the scope of an internet board and my mathematical or scientific knowledge. I can’t begin to properly understand a fourth dimension let alone the many that string theory works with.
