Technically forward "time travel" which is really just a relatively accelerated passage of time between you and any remote point has been proven and is very possible. Extremely small movements, but still.

I strongly think that time travel is impossible due to energy requirements being unfeasible, but I am totally against any argument that involves "lol causality". As if the universe cares about who your grandfather is or isn't. You'd be creating a new timeline just by your presence.

As far as I'm aware, the absolute best you can do is traveling back through a man-made wormhole. Thing is, you can only go as far back as when you first opened one end. So even if we managed it, you wouldn't be able to meet Jesus, you'd only be able to go back to 2120 or whatever.

That's assuming you can create a stable wormhole, which assumes you can make matter with negative mass. There's no reason to believe either assumption is true, even if it works out mathematically.

>>12219778
Honestly I thought it wasn't possible but now I realize it could be possible (No I won't elaborate)
Although if you were to enter an hypothetical time machine, who says you wouldn't be teleported in the vacuum of space, since planet earth would have moved very fare away from were you originally were when you time travelled ?

Entangled particles don't communicate faster than light through space. They communicate faster than light through time. It's helpful to think of every particle as having a string attached to it. By interacting with a particle you also interact with the string which stretches back to the big bang and can travel back up through time to "instantly" reach any point in space. Spooky action at a distance. A way to manipulate these "strings" is developed and used to send messages back in time, but only to the point the detectors are built. You can manipulate events further back, but it's usually a shot in the dark with the lack of precision. Of course it is abused and paradoxes occur. The problem is of course that time will loop back on itself an indefinite amount of times until random quantum events stabilize the timeline. The problem is that because the string loops back to the big bang quantum randomness can cause a tiny fluctuation then which leads to huge differences in the new timeline. Like no more milky way sized differences. Fermi paradox. The universe isn't vengeful and destroys your species existence for messing with time. It's just statistically the most likely way to correct the paradox you create.There will be less and less intelligent life as the universe keeps resetting. Judging by how quiet it is in this timeline, I would say we're getting near the true end.

lmao bro just stop moving through time.
and then move through it in the direction you desire.

I've been studying time travel with wormholes for the past year and it's interesting. Pretty much any form of FTL is automatically a form of time travel.

>>12220312
It isn't even a matter of causality but a matter of the universe seems to actively prevent it, according to Hawking's Chronology Protection hypothesis.

if you can create a wormhole (which do exist, the only question being if one can make one stable, which would be possible if negative mass exists) then you can travel both forward and backwards in time, but only backwards up to the point the wormhole was created.
