I love how you're so absolutely sure of an uncertainty. Science has often proved its own theories and hypotheses wrong, yet I'd be willing to bet you'd believe they were true up to the very moment they were disproved.
See, this is what bugs me about these debates. A scientific theory does not claim to be a universal truth; it is an accurate model of our understanding of the universe, based on the information we currently have. No scientist would claim that we are going to keep any theory forever, because if new and contradictory evidence is found, the theory is modified.
Here's an example: Is 17th century Newtonian physics 'true'? Newton's laws still hold--tennis balls follow parabolic trajectories, objects still have friction, and for 99% of our everyday interactions they work perfectly fine. So then Einstein comes along and discovers that Newtonian mechanics don't completely describe the interaction of masses at the very very large or very very small scales, so he comes up with new formulae that describe them more accurately in those situations.
Einstein didn't 'prove [Newton's] theories and hypotheses wrong.' He built on them, refined them, and made them more complete. Whatever is happening in the universe is still happening, the only thing that's changed is our understanding of it.
