Improbable for a bunch of reasons, but not “absolutely impossible.”It is absolutely impossible you will ever fuck Scarlett Johansson while I watch. If the scenario arises where it's about to happen I promise I will close my eyes to ensure I'm technically correct
Dont underestimate my drive to be correct on the internetImprobable for a bunch of reasons, but not “absolutely impossible.”
i think shows like Rick & Morty and pop sci fi have convinced people that a lot of miraculous technology is right around the corner
like for real you will hear people talk about uploading brains and making clones of people and teleportation and stuff, as if science will make all that possible. people may not believe in magic or religion anymore but they do have a bunch of faith in a techno utopia waiting just around the corner.
as with anything, ill believe it when i see it
I dont know what that implies though. Can you bring people back from the dead? Because if you go back in time theoretically you should be able to interract with people who are now dead.
That sounds nore like reverting the state of a certain perimeter‘s content. The rest of the world/universe will remain in the present, so this isnt time travel but a reconstruction.
Its not my idead of time travel, its the only real way of time travel. You can only travel through time if time changes for you, while you don't. If you sit outside and watch time reverse in a contained environment you arent travelling. Nor is anything within the changed environment traveling, but just reversed to a previous state.If your idea of time travel is that everything in the universe has to be exactly reversed, I don't think that can ever be in the hands of humans. And even if it were to happen, you wouldn't be witnessing the travel, because if you exist as you are in a time before now, that means the universe wasn't accurately reversed.

The state of matter can change due to the forces exerted on them, but if you had the computing power to analyze and store the exact state of every particle within a certain perimeter, then had the right amount of force and accuracy to change each particle's state and position back to a previous one, isn't that essentially time travel within that perimeter? The more mass, the more energy this requires and more complexity requires more computing power and accuracy.
It would certainly be an insane setup, but it seems technically possible.
I'm not going to ask an actual physicist though, cause every time I do they roll their eyes and yell about the speed of light or some shit.
The equation for time dilation:
t = time you as a human observe
t0 = time passed on say....Earth
v = your velocity away from earth
c = speed of light constant
In order for time to even stop (not going backwards in time), you need to hit the speed of light (actually not even...since at speed of light, you get a divide by zero error)
However! In order for you to hit the speed of light:
The equation for velocity given energy:
v = your velocity
m = your mass
E = energy
c = speed of light constant
The square root in this case MUST equal 1. The problem is, no matter how much energy you throw at your mass, the mc2/E value gets infentisimally small, but never 0. As such, the square root can never be 1 since it'll always be 0.999...999
- To slow down time to a standstill, you must be traveling at the speed of light
- To be traveling at the speed of light, you must be providing literally infinite energy
- As such, the best you'll ever achieve is super super super slow forward movement of time, never a full stop nor movement backwards in time
Uh... this is quite complex for me, but is this really in relation to the method I was talking about?
Like for instance, you have a hamster in a controlled environment. You begin recording the state of particles in the environment. The hamster dies at day 5, you move the particles to their state at day 1. Hamster is alive now. According to what you posted above, that's impossible?
Everyone knows all you have to do is find a wormhole and jump through it. smh
That's not time travel.
What definition of time travel makes it not a paradox then? If the entire state of the universe is reversed, rather than a controlled local area, you won't notice that it was reversed. So that's not really time travel either. If you yourself somehow got a magical genie wish to insert yourself into a previous state of the universe, yet again, that's not time travel, because you weren't part of the equation of the universe you're now entering.
I'm trying to think of what seems like a more realistic approach to time travel.
Maybe I'm misunderstanding you...
Even if you were to revert a set of particles to a "prior" state such that it was equivalent to say...its state 5 min ago, it's still done in the context of time moving forward.
Take a basic document revision control system
1. Save a document at t = 1:00pm
2. Edit and save document as revision 2 at t= 1:05pm
3. Restore 1:00pm revision 1 at 1:06pm
Would you consider this information to have traveled back/forward in time?
Back / forward is just a concept. Time just means things are in flux. If we remember a state and have the capability, we can return something to its prior form.
But it's past just as much as you looking a photograph taken 50 years ago is past.
You're gonna have to overcome the speed of light, which at this point, barring some creating outside thinking, is considered impossible.I’m going to say going back in time is possible and I don’t believe in multiverses.
In fact you can see the past when looking up at the night sky and you wouldn’t even know it. The further objects are away from you the further back in the past they actually are.
Scientists have claimed that aliens 65 million light years away could look at Earth today (providing they had some damn good telescopes) and see Dinosaurs still roaming.
I believe there is something in that which if the past can be seen then it is only a matter of time to figure out how it can be reached.
Being able to look back in time is not the same as actually going back in time and interacting with it.But it’s not a still image is it? It’s a physical look into the past.
I doubt it.With an inertial mass reduction device, like the one in the US Navy patents! FTL travel could be possible.

Well yeah, but we weren't breaking any laws of physics to do that.Talking to people from one side of the planet to the other would have been considered impossible at one point.
But isn't mass the reason why FTL cannot be achieved?I doubt it.
Well yeah, but we weren't breaking any laws of physics to do that.
No, it's you seeing light that is not the situation, but an illumination. It is just a photograph (or moving pictures if you will) imprinted in space, moving forwards at a certain speed and you are able to take a look in that. The actual situation that you see is long gone. It is a memory of a past thing, the way a picture is. You can perhaps see several pictures in a row, but that just makes it like a movie, many pictures in a row. The actual situation doesn't exist anywhere. At best you are looking at a documentary that happened by accident.
Well, I don't know if there's any one problem, like mass. The only thing that travels as fast as light is light, which has no mass. Tachyons, which are only hypothetical, might have negative mass? However the hell that's supposed to work.But isn't mass the reason why FTL cannot be achieved?
To be able to travel back through time would require history physically existing somewhere.
You could perhaps create a copy of the state the world used to be in, if there would be some way to change atoms at your will, but you would still be in this current time. It's not time travel, it's just some really obnoxiously autistic way to make a fully accurate period piece setup.
I wish I could have save states so I would cheat like motherfucker in the game of life.Sorry yes your idea is like going back to a previous save point in a game...if the universe is indeed a simulation I don't see why it wouldn't work.

Mostly, according to physics as we know it, it takes infinite energy to travel at the speed of light, so that's a problem. Depending on how you look at the equation, it's also a problem of infinite mass. So unless you have some way to reduce mass to zero, I don't see how we're getting anywhere.
Stretching and altering spacetime seems like a more plausible way of getting anywhere at FTL speeds, but even that is crazy outlandish with our current understanding of the universe.

I think I would be pretty rad if the actual solution/invention of time travel ends up happening in this thread.
I believe in you all.
