I agree that we still have much to learn, but I still don't agree that anything we learn is going to make the basics we know completely wrong. It would also have to make everything we see completely wrong, as well. That's the part I have trouble coming to terms with. How do you who think we could be wrong explain how these mistakes don't manifest themselves in what we see of the universe? Does the speed of light hold in all cases except in some few that conveniently explain some macguffins used in some sci-fi novels?

how that makes faster-than-light communication any more possible is not a theory at all, but just an opinion based on your own interpretation. Your not seeing it does not preclude it happening.

How do you who think we could be wrong explain how these mistakes don't manifest themselves in what we see of the universe? seems to ignore that around 95% of the universe is not understood, that not just due to minor omissions from knowledge but pretty much just not understood as to how and why at all. {EDIT: it is also possible that there may be more than that of the universe that is not understood, it was only a short time ago that we did not know about the "missing" 95% and nobody much expected anything was missing from the models, perhaps there is more yet to become apparent to us}
As I said, I have an open mind on these things and without being silly about it history tells us that the theories/models/laws of physics are open to change over the course of time. It seems foolish to me to align oneself to a belief that current knowledge is immutable. As you probably know, there are stated opinions among well regarded physicists and cosmologists that to understand things seeming to become apparent to us about the energy and mass structure of the universe that it may be that special and, more particularly, general relativity may change in some way yet unknown.
I'll leave it at that as I cannot see any argument that I can produce will change any unswerving belief of others that the physics as it is now will not change in any substantive way into the future.
