And what are the chances of that, exactly? Relativity and quantum mechanics are the two fundamental pillars of modern physics, and the principles within those fields have been repeatedly tested and continue to be tested today. It is very, very unlikely they can be wrong and hence, the only way wormholes or other space-time manipulating technologies will become possible is through exotic matter. Your analogy fails simply because ancient Egyptians don't know as much about the nature of the universe as we do today.
“ Some people will be very disappointed if there is not an ultimate theory, that can be formulated as a finite number of principles. I used to belong to that camp, but I have changed my mind.
Mass manipulators? Have you been reading too much science-fiction? Or probably the articles of science-fiction enthusiasts who point to the possibility of manipulating the higgs-field of matter, something that isn't even proven to be possible theoretically? And even if you could create massless spaceship, you still can't go faster than the speed of light without violating causality (you would arrive before you even left).

As i said its arrogant to tell we discovered every law of physics. Gödel's incompleteness theorems postulate that its impossible to get a 100% ToE.
From wikipedia:
"Stephen Hawking was originally a believer in the Theory of Everything but, after considering Gödel's Theorem, concluded that one was not obtainable:
“ Some people will be very disappointed if there is not an ultimate theory, that can be formulated as a finite number of principles. I used to belong to that camp, but I have changed my mind.

And also but this thing is debated whether it violate causality:

Originally posted by piotrburzThere also proposals that time has another dimension. Also other dimensions can have different time flow rates.
Heck even in our universe time flowed slower at an early stage www.newscientist.com...
Some static fields like gravity are excluded from the influence of time. So in layman terms its "FTL", if Sun magically vanished, we wouldn't need to wait 8 min and 43 sec to get out of solar system and orbit galaxy.
And universe expand faster than light, the supposed explanation is that spacetime can do such things, but no one can explain how space time can propagate into "nothing". That's a mystery we could never answer.

Incorrect, it is not arrogance if a principle has been continuously tested and will be tested and has stood all of those tests for nearly a century now. If anything, it is the only rational conclusion that we have figured out most of physics in regards to relativity and the standard model. Even your analogy to Newtonian mechanics and the quantum revolution fails, because Newtonian mechanics still serves as the fundamental principle for the macroscopic world and only fails at the quantum level. Most engineers, for example, will never have to learn a single principle from quantum mechanics and get by fine with Newtonian mechanics.
As for ToE, that is much more likely to be a reality within a few decades or even centuries than interstellar travel. If it really could be proven mathematically that it is impossible, then why do we continue to fund particle theorists that work for a ToE? And Stephen Hawking is not infallible despite his great achievements. People seem to quote him as the supreme authority on everything. He's not a string theorist, he's a cosmologist. This isn't the first time for Hawking to talk about a topic that outside of the realm of his expertise.
"Many theoretical physicists have devoted significant fractions of their careers to trying to solve this problem. Some have argued that new particles and new forces are needed (and their theories go by names such as supersymmetry, technicolor , little Higgs, etc.) Some have argued that our understanding of gravity is mistaken and that there are new unknown dimensions (“extra dimensions”) of space that will become apparent to our experiments at the Large Hadron collider in the near future. Others have argued that there is nothing to explain, because of a selection effect: the universe is far larger and far more diverse than the part that we can see, and we live in an apparently unnatural part of the universe mainly because the rest of it is uninhabitable — much the way that although rocky planets are rare in the universe, we live on one because it’s the only place we could have evolved and survived. There may be other solutions to this problem that have not yet been invented."
That's great and all, but can you cite them in peer-reviewed articles or at least any other laboratories that have been able to repeat the experiments and have arrived at the same conclusion?
Again, you don't seem to understand the strict line between "theoretical" and "practical". There are also theories that there are more than 3 dimensions of space, and that inter-dimensional travel or "stepping outside of space-time" can be used to cover vast distances in outer-space. But in the grand scheme of things, it really doesn't mean anything in terms of applications to the real-world. I doubt we would have technology that could allow for inter-dimensional travel (assuming extra dimensions exist) any time in the distant future, if ever.
Originally posted by piotrburzAs with most of the inventions its only a matter of time when theoretical will become practical.
Originally posted by piotrburzAnd i didn't say it will be in 100 years, DARPA in this matter is utterly optimistic, and i sense some kind of "money scam". Someone get a "fat grant" of million dollars for doing absolutely nothing, just wasting time. Bureaucracy and big government at its finest.
Originally posted by piotrburzI'm much more curious why the hell you think we as a mankind will never achieve interstellar travel, yet you believe that some UFO could.
