Past Time Travel: What Paradox?

I don't understand this paragraph. What does reversing time have to do with time travel have to do with sending information faster at the speed of light? Maybe I simply don't understand your terms, can you elaborate?

RE: Past Time Travel: What Paradox?
I think time is illusory. Hard to explain but I think that we only experience a present state. Our notion of time comes from, in my view, from how our brains store 'past' events in our brains and how our brains work. This gives the rise that there's some nebulous future and that we can go back or forth, when all there really is, is a present state.

This becomes doubly so when you see that time is relative, that there is no absolute time-reference you can guide yourself and because of that there's localization, both in time and in space. The faster you approach a heavy enough gravity well, time "slows" proportionally down, just as it "speeds" up the faster you move, relative to a stationary observer. This, to me, just illustrates that there is no time and that gravity is just space folded unto itself.

If you think time is an illusion, try showing up at the airport 20 minutes before your flight leaves.

What is the difference between time being illusory or time being real? I don't see any meaning in those words.

That's just conventions of states, and why shouldn't I follow these conventions of time?

Thinking time is real leads to the thinking that we can go back in time, when there's no "time" to go back to is basically the gist of it.

That would seem to be analogous to sensory experience. The way we experience color is real for us given the nature of our organisms but other creatures with the capacity for sight might lack this feature and/or have the capacity to see in wavelengths we do not. But each creature is experiencing the way the world around it looks to a creature with the capacity for sight. The world is real. Sight is real. Each creature's particular articulation of sight perception is real too. None of these is illusory. It's just that the final bit is malleable in its expression, but none of them is 'counterfeit'.

If there is no "real" time to go backwards in, going back in time would simply be tantamount to going back in illusory time. Nothing is gained from this word game unless you say what the difference is between having real or illusory time.

Time is like a river it only flows in generally 1 direction going back simply being would be pointless.
We can send particles and photons back in time this proves a couple of things since we can send particles of light back in time.

According to this theory, when you go back in time and murder Trump, you just murder a Trump from a parallel universe, and I disagree with this kill Trump  stuff.
