Time travel is impossible. Not "we can't do it", but it is a physical impossibility.

It is not a revelation to know time does not exist other than a measure of our perception of change and memory.

Paradoxes arise from time traveling at all, in any fashion.

There has never been a time traveler from the future.

>b-but these equations say wormhole this, spacetime that!
Shut up. It's stupid and you know it. They are overthinking what is relatively simple.

There is no time in any shape or form, there is no spacetime. Only space. And it is infinite.

Anything else is purely retarded.

Something Einstein said about our perceptins of time and how the method everyone believes is trimetravel (Going super duper fast) would stop time instead of gaing back, and we would gain so much mass it would be impossible.

Infinite point is an aspects of "perfect" mathematics. In actual physics, there's a minimal distance where the atoms/electrons touch and do whatever atoms and electrons do when they touch each other.

If you are a looser in this time stream, chances are you'll be a looser in any other time stream as well. Why don't you stop daydreaming about time travel, including that regret highway you are currently on, and pick up a book on Machine Learning; Maybe, help other loosers make better decisions.

But there isn't. You can go ahead and apply certain events to certain "times" but that doesn't really mean anything. It's always now, there's no time to go back to because it's gone.

Yes, things are changing. You are correct. Why you think that means time is passing, I don't know. Things just occur. That doesn't really state anything for against the objective existence of time

>> No.5035412

>>5035402
things change in a predictable fashion. this can be measured, in part, by the passage of time. i dont understand why you think that time doesnt exist. maybe a better example would be things traveling at different speeds?

See, no.

You don't measure anything by the measure of time, you measure how things change by how other things change (your clock)

Space isn't "real" on its own.
Time isn't "real" either.
In our reality you can't have one without the other.
That's spacetime. Space and time together form our reality.

If you just had space and no "time" nothing would move, everything would be black because light wouldn't move.

You can't have time with out space because time is the duration something occupies in space.

This is where you lost me. You sure talk confidently and matter-of-factly for someone who I am absolutely sure cannot offer a single alternative to "spacetime" which is even 1/1000th as useful at predicting actual observations.

So are you ready to admit that it is possible every word that comes out of your mouth isn't pure fact and that maybe you're wrong?

Furthermore, you need to realize that "time travel" depends on who you are talking to. I think anyone who has ever given it any serious thought has long ago abandoned the idea that you can _literally_ go to your past and make modifications and then travel forward as the the universe magically applies all the changes you've made to the present.

There are alternative notions that resemble this literal idea of time travel, yet they are still referred to as "time travel". So you should more clearly define exactly what it is you are talking about.

>no spacetime
well you are wrong faggot, there was an experiment in the Earth's orbit that showed space was curved and it has been shown in experiments the faster you travel, the slower clocks tick.

While you are right in the fact that you simply cannot go BACK in time (as this is retarded) you can however slow down time or perhaps even stop it.

The only reason people decide to be faggots about time travel is because when you go faster than light, the light you left behind takes more time to get to your destination than you do, so if you were observing from the outside, you arrive before you left. However, this is not physically correct, the only reason this appears this way is because the light SENT OUT takes longer to get to that point.
