why isn't time travel possible?

>> No.8268577

Because reality isn't a science fiction movie.

It's not impossible it's just far beyond our doing. It's also boring when you consider that their is no past to travel back to because only the present exist.

Well anon in all honestly it probably would be possible by now if the Christian dark ages would've never occurred, seriously fuck Christians, biggest cucks of all time.

Time travel to the future is possible, in a relative sense, because you can slow down your time relative to other frames of reference. Time travel to the past is impossible because causality is the foundation of reality.

It might be possible. We don't know.

Time travel is generally talked about as though it were not possible, because there has not yet been any proposed method of time travel that is anything close to feasible.

Moreover, even defining time travel is problematic. We can imagine various sets of rules which might govern time travel, but examining the things we already know to be true about causality, incorporating these hypothetical rules often has unforeseen consequences that make them self-inconsistent, nonsensical, or at the very least, complicated.

I could go into deeper detail, and will do so if anyone is interested, but google could likely do a better job of it. Check out, "Novikov self-consistency conjecture."

The best argument I've heard is Stephen Hawking's (which I'm sure I'll butcher). Basically, it works this way: any portal to the past would absorb matter/energy and send it to the past, allowing this matter/energy to travel forwards in time only to be sent back through the portal. Basically, it's a feedback loop. As a result, the portal would be destroyed by the immense amount of energy hitting it. Traveling to the future could be possible, though.

You should change psychiatry with psychology. Psychology is the soft 'science' bullshit, psychiatry is an actual branch of medicine (every psychiatrist has an MD by definition).

It would be effectively the same, familia. If done properly you could step into a box and blast 1 year into the future in what seems like 10 seconds.

well...

if you could go faster than the speed of light while still being affected by relativity.

So far no one has mentioned the quantum eraser experiment that seems to change what we know about causality.

>> No.8269722

>>8269667
Just googled the quantum eraser experiment and read some of the basics (admittedly I don't really understand it, but that's kind of quantum mechanics in general), how would it rule out time travel? I understand how causality would be problematic, though.

U wot?
Christianity existed both before and after the dark ages.
Christians were responsible for the Renaissance and the industrial revolution.
