I look at it this way. Back in the early 1800's, it was thought that if you went over 25 MPH, you would suffocate and die. The steam locomotive proved that wrong. I think there is a way beyond the light barrier, or over it, under it, ignoring it or whatever. We just have to find the way to do it, we already have theories, we need a way to put them in practice somehow. Same with time travel. Who knows, maybe some of this was done as early as World War II or sometime between the 1930's to now and it was covered up. Time travelling Nazis and U.S. Navy men and Roswell aliens aside, I admit I'd like to see proof, but there is and was a lot of high strangeness that needs to explained. My grandmother used to have books on a lot of these things.

Conspiracy theories aside and returning to face value, I do think there will be such breakthroughs, that is if we do not blow ourselves up first.

I do think there will be such breakthroughs

That is a pure leap of faith, based on absolutely nothing. The breakthrough you foresee is the ability to step out of this space-time reality, onto some other reality and then step back in. That is pure fantasy.
