Past Time Travel: What Paradox?

[Sal]

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

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

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.

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

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.
