| Unfortunately many of the secrets of the universe we cannot experiment with our current technology, but such limitations have been overcome before. But they are the BEST available theory, and it is mathematically proven, so wether it is real or not, it is very possible.
Btw, gravity, inertia, even the THEORY of relativity, which you claim to support, has been supported by experimentation, but never actually proven.
Also the big bang is the only theory that was able to explain why all the galaxies are moving apart, and the background radiation (the dim everpresent after shock of the big bang) |
