Time travel is impossible / time does not exist

My opponent attempts to show that relativity is false by citing a few examples. Now, that is a lot of new arguments posted in the last round, but I will address them all. 1)Equivalence Principle [1] My opponent falsely suggests that the EP would predict no time dilation. The error in his (and the website that he cited) argument is claiming that, "it is fundamentally impossible to distinguish the effect of gravity on Earth from that of accelerating through space at the rate of 1g. " This is not true, more accurately; it is "the gravitational "force" as experienced locally while standing on a massive body is actually the same as the pseudo-force experienced by an observer in a non-inertial (e. g. accelerated) frame of reference. " Since time dilation is a result of velocity and not acceleration, it is not included in the EP and therefore, causes no violation. The EP has also been tested many times, mostly with centrifuges, planes, and rockets. 2)Twin Paradox [2][3] Here are two in-depth explanations of the twin paradox, one by wiki (has many sources backing it up, but if you are a wiki-hater then) and one by Virginia Tech. The short explanation is that special relativity only applies to non-accelerating reference frames (at least, non-accelerating in relation to each other). When one twin turns around to come back home, there is acceleration and a change in reference frame. 3)Occam's Razor My opponent claims that time is an assumption and so must be dropped according to Occam's Razor. Three things are wrong with that. One, that it completely ignores the tests that we've done which prove time is real. Two, my opponent's alternative is "there are other logical elements that could affect a clock…" which actually means the alternative has more assumptions and so Occam's Razor would suggest rejecting those. And three, Occam's Razor does not "prove" anything exists or doesn't exist, so even if we accept this, it doesn't satisfy the resolution. My opponent goes on to state, "We need to get out of that silly mindset and realize there is ALWAYS possibility for even the most fundamental scientific theories to be completely wrong. " No, they cannot be "completely" wrong. While they can be imperfect and need improvements. Even going back to Newtonian physics, we know that his equations are not 100% accurate, however, for most everyday calculations, they are pretty damn close. Close enough that we use them when building cars, bridges, skyscrapers, and most everything else. They are "right" (right enough) for 99% of the things we do. They just don't explain that last 1%. And it is likely that we'll find that relativity is right for 99.99% but doesn't explain that last 0.01%, then something else will come along and it will be right for 99.9999% and the pattern will continue, but at no time will we go back and say, "Relativity is completely wrong. " Relativity is not going to suddenly stop being able to predict things that it has already predicted. The time dilation that has been tested and proven is not going to suddenly stop happening one day. I thank my opponent for this debate and thank the voters that take the time to read it.
