is time machines can exist
| into the future yes.
into the past, probably not.
| Cryogenic sleep probably? Not technically travelling through time though. Just a thought.
| If you build a spaceship wich travels the speed of light, time will go slower inside the ship than everywhere else. This makes it possible to travel decades into the future spending only a few years in the ship
| Even when youre in a car youre traveling to the future but the difference is so small that its unnoticeable
| And thats because its a law of nature to never pass the speed of light wich is the ultimate maximum speed. So time is slowed down
| I guess when time is slowed down that gives the illusion of going faster than light?
| Its technically possible to go to the past/alter the past if you create a parallel universe in the progress, just like in re:zero and steinsgate. Ofcourse no-one knows how and if thats possible
| But when time traveling is used in the same universe in tv shows and other media.... its just... horribly frustrating to watch

This would have been easy if the ship were massless, and you can't have a massless ship. Only massless particles can ever get to that speed — anything with mass require infinite energy to get to light speed.
| Time is slowed down because of your acceleration. To light, you are nothing. If you are moving at the same speed, 'when' becomes 'whenever' — and to observers looking at you, well, you're nothing either.
Relativity dictates this. To someone moving, those unmoving, or at a slower speed, appears to be static — but if you were the one unmoving, you'll see them.. well, moving. This is greatly exaggerated at light speed, where everything is static, in light's PoV.

We're relying on eye-ball proof of the multiverse theory, and we're also assuming a lot of things here. Plus 'creating universe' sounds like a task virtually impossible to do — but hey, I'm not a multidimensional deity with the ability to poop out universes. What do I know?
| You want to go to the future? Just sit. You are already moving at a speed to crawl to the future. We're all time-travelers.
| >>261567 >>261584
Technically it would be possible in the future, you don't need to hit the speed of light, just get close enough. It's more than likely if we can get a full fledged spaceship we could get it to go 2x10^8 which would be good enough.
| >>261586 this.
theoretically we could also travel trough a 4th dimension (if there is one) to take a short cut. Nothing to do with time travel but still an interesting idea.
watch this; https://youtu.be/N0WjV6MmCyM and some VR 4th dimension videos and you will kinda get what I mean.
| >>261592
That 'dimension' is usually time, but some misty-wooby people would call me out and say it isn't.
>>261586
Nothing in my post indicates the idea is impossible for near-light speed. Energy requirement becomes exacerbated the closer you are to light speed — and in light speed, you are basically facing an infinite amount of energy requirement, thanks to those mass you, and the ship, would have.
| >>261586
To accelerate a mass as massive as a ship to 0.1% the speed of light, you need a lot of energy. I'm talking about hundred of terawatts of energy. It's not that it's impossible, no, no — it's just the number doesn't line up for a foreseeable future.
You can be optimistic, but sometimes having a rain check does help.

That's constructive, and surely adds to the conversation we're having. I hope your post made you giggle, and thus you doesn't need to contemplate the very fact that not all conversation needs to devolve to a meme slap.
| >>261606
I mean it's not gonna happen in my lifetime but it's bound to happen in 10,000 years time
| It should be possible to travel time since time is not linear.
But to travel time you would have to give up your physical form, so, no, no human can ever travel time, as if they do, they stop being human.
| >>261549 >>261586
Well, you don't really need speed to slow down time, you need gravitational force, like a black hole.
Make a ship orbit around a black hole, close enough to be able to escape, and that ship will perceive time to be slower.
Funny thing is, if you throw an apple into a black hole, that apple will not reach the core of the thing within your lifetime.

| is some point that a human can go through time from time to time?
