Because every possible time travel possibility requires infinite energy.
Thanks, I'll check it out
time paradoxes and causality breaks
As if the universe gives a shit about paradoxes.
Doesn't it depend on how anon defines paradox?
If you think you "cannot time travel" because the universe is worried about you shooting your own grandfather or otherwise preventing your present from coming to be, you're an idiot. This is beyond any doubt. There is no policeman that stops you when you build your time travel machine and then says "do you know how many paradoxes you were about to create?" It's utterly absurd.
Well it could be a paradox in the sense it creates utter chaos in another era or reality? It could "melt" the time line?
The more I think about it, it does sound kind of weird.
What do you make of this wiki pg?
https://en.wikipedia.org/wiki/Temporal_paradox#:~:text=A%20time%20traveler%20would%20not,paradoxical%20and%20therefore%20logically%20impossible.
"Logical impossibility" is a nonsense argument. It's like trying to debate the "logical impossibility" of some of the absurdities found in Black Holes or quasars or whathaveyou. The Universe is full of weird shit, nobody cares. Strangeness or incomprehensibility is not an argument. An amoeba's ability to understand the dynamics of the universe has no effect on what is or isn't possible.
An actual argument would be something like infinite energy requirement or the creation of parallel universes (so you can never go to the past, just a 'new' past in a new timeline as your mere interference by existing has caused a divergence). But paradoxes are moronic.
paradoxes signal a flawed understanding of something. if a paradox pops up it means you fricked up in your assumptions. thus, time travel the way you think of it, which is what Hollywood thought you to think about, is logically flawed.
As I said, infinite energy is more likely the real reason. It's not the fact you'd do something strange, it's just that you can't. Like the idea of antigravity.
Why, if time ain't real and the universe is stationary past and future events are just dimensionally overlapping
All the events that future time travelling (You) will do have already happened and your grandfather didn't die.
then where did you really go anon? we don't have determined future
Its only the future for you. For everyone else it was the past. If at some point in the future you will invent a time machine and go back in time to see your grandfather, you could ask him what you did/will do, before you invent the machine.
>hard determinism
Disproven by probability. The future is by definition a superposition.
>There is no policeman that stops you when you build your time travel machine and then says
>build time machine
>get shot
hey man, nobody said the time cops were literal policemen. they don't even get paid.
Paradoxes don't exist, because the Everett interpretation is true. If you time travel, you just go to an alternate timeline. You can kill your grandfather there and you simply won't be born in that timeline. You can apply this to any supposed paradox. Whether or not that timeline has always 'been' or starts with your interference, or perhaps both, is unknown. Maybe this is why you need infinite energy to travel in time.
Going to an alternate universe isn't time travel.
It would take infinite energy to reverse causality because there are infinite events happening simultaneously that you would have to reverse to reverse all of time.
you don't even understand what you mean by time travel, all you know is from the moovies
Yeah, probably. Just got high and was curious. What do you mean by time travel?
you can only travel in the future of some other frame of reference (not yours). timeflow in your own frame of reference is fixed at 1s/s
Are you suggesting if there are multiple universe then it can be done?
nope. going to another universe wouldn't be time travel.
you time travel as we speak. because you are in a gravity well you enjoy less overall time in this universe. less than GPS satellites. as seen from the satellite's view, your clock ticks slower.
the same effect is present across your body. your head is technically older than your feet. time passes slower for your feet when you stand upright
Thats a interesting way of looking at it.
because paradoxes
you could imagine e.g. 2 time dimensions where you can travel freely in 1 without paradoxes
e.g. go back to the time you were born, but not the "previous" time you were born
Imaginary time
>Why is time travel seen deemed impossible?
Time Travel itself isn't deemed impossible, iirc Einstein's equations actually sets up framework for time travel.
the thing that isn't agreed upon is rather one can time travel within the time-stream one originates from.
so time travel is "possible"?
hows that, exactly?
>hows that, exactly?
where does that time you travel to exist anon? or do you suppose you would rewind time for everybody (whole universe) but only uniquely you would still remember shit? what about countless super advanced civilizations out there in the universe? do you rewind them with your time travel?
>where does that time you travel to exist anon? or do you suppose you would rewind time for everybody (whole universe) but only uniquely you would still remember shit? what about countless super advanced civilizations out there in the universe? do you rewind them with your time travel?
from my understanding, the time travel only impacts those traveling in the time stream,
it doesn't rewind time for anyone outside of the 'ship' or whatever is used to travel backwards.
is this just dreampt up bat shit or what?
I don't understand what you're asking,
>dreampt
Are you asking did I ask ChatGPT to make that picrel? or my belief? I'm a bit confused.
this is what I sincerely believe from information I've read, and that is my handwriting anon.
you don't understand what you are asking
I didn't understand the question at
I now see you meant "Dreamt" but you put "Dreampt" so I assumed you were asking did I use GPT (combination of Dream and GPT) to come up with this.
but either way, my replies are easily to follow if you want to follow them, if they seem difficult to understand that's probably a You-problem.
again, iirc (as I don't know it by memory) the way that entropy works or something along those lines allows for time to flow backwards.
But the arguments being spoken of states that you're not capable of traveling in your own timeline and what happens is you end up diverging into a new timeline. this upholds the "grandfather paradox" in such a way that if you did go back and shoot your grandfather, yea he would die in that timeline and in only that new branch does your birth never happen.
See picrel for crude drawing;
Right? Why would they say that when actually its impossible not to travel through time.
you moronic? i can not travel through time right now
look.
see? i did it.
Nope, it took time between typing see and i did it, so you definitely didn't stop traveling through time.
no, i did. i stopped and started again. youre exercising willful ignorance anon. here, i'll do it again
see?
Nope you have a different timestamp therefore you had to travel through time.
you always travel at 1 second per second (for you) and there's nothing you can do about that.
maybe ~~*You*~~ can't. too unskilled to percieve my pausing of temporal progression. I feel sorry for you, and all anons like you
You had to unpause it which would necessarily take time, so you obviously couldn't have actually paused it, then unpaused it, give that once pause it would have to stay paused if you actually paused time instead of just pretending.
>when you snooze an alarm, it never goes off again
anon its like you're not even trying. please be serious
You said you paused the clock, not snoozed the alarm, If you unplug the clock like you claim to do, the alarm can't go off again no matter how many times you push the snooze button.
the universe doesnt run on electric circuits anon, you're really stretching the metaphor, i was just trying to put it in terms you'd understand
It was stupid terms because if you pause the clock, it will never reach the new time the snooze alarm waits to arrive before going off again.
forgive me for trying to stretch your understanding to levels that we now know are impossible
No, you are a moron who doesn't understand how time or snooze buttons work since they just delay the alarm, they don't pause the clock.
even galileio was persecuted like this. god help you, im just glad i wont be burnt at a pike for trying
"Trying" and pretending is the closest you will get since it is impossible not to travel through time.
i hope one day you understand just how wrong you are, friend
I hope one day they find a cure for your moronation. Until then you will just have to keep traveling through time waiting for each day to become the next day until that day comes.
No, time is relative, the rate changes depending on several factors including weight, speed, and distance of the body from other massive objects.
>No, time is relative
never for you in your own frame anon, how can you frick up like that? do you even understand the words?
No, clocks aren't in your frame of reference, so you could be observing several different clocks moving at different rates such that you could actually say how many seconds were passing for you each second.
>No, clocks aren't in your frame of reference
what do you mean? the clock measuring your frame of reference is on your hand you moron. you look at it and you will always see it tick at one second each second. boy you really are slow so you might be on to something
You can put one on your feet too and it could get out of sync with the one on your hand, hence its not a constant 1:1.
what if you're in bed?
Urine bed? Are you trying to tell us that you pissed the bed again?
>never for you in your own frame anon
Wrong https://en.m.wikipedia.org/wiki/Ladder_paradox
>by the time the front of the ladder collides with the back door, the back of the ladder does not know it yet, so it keeps moving forwards (and the ladder "compresses"). In both the frame of the garage and the inertial frame of the ladder, the back end keeps moving at the time of the collision, until at least the point where the back of the ladder comes into the light cone of the collision
All your parts are separated from eachother and have relative time difference
A bed, not a ladder.
>All your parts are separated from eachother and have relative time difference
in a gravity well maybe. when you travel, all of you travels together as a single frame of reference. you'd have varied frames of reference along your body either when falling in a blackhole either when bits of you accelerate faster than other bits of you which is always bad news for you.
but if you are traveling with all of your atoms, all will be at same speed as your brain which is (You), so they all share the same frame unless you are in a gravity well and there's a differential across your body
No, whenever you walk, your legs are traveling more than twice as fast as your upper body since they have to constantly go back and forth instead of forward at a steadier rate like the rest of your body.
>when you travel, all of you travels together as a single frame of reference
And when you travel at the speed of light there is no way for information to propagate from your ass to your dick until your dick stops and your ass catches up
>And when you travel at the speed of light
Oh my bad, when you travel at any speed which causes relative displacement, aka literally at any speed, you just don't notice it at smaller speeds which is why c is used as an example, you braindead wojakposter
Time travel aint Christian
do christlets really

Because it's illegal
Which is interesting that Japan (iirc) made it illegal for time travel.
You don't make laws for actions not possible.
really makes yu think.
no, it is possible hahaha. there are even time machines ~
you should honestly think anything is possible anon.
It's possible but the moment you do your entire planet and the surrounding ones cease to exist.
If it wasn't we'd already have done it.
