What's the real possibility of time-travel?

Just drive a car faster than the speed of light desu.

>What's the real possibility of time-travel?

Zero.

0 to the power of 0

can't happen, because time isn't an actual thing

to "go back in time", you'd have to force every particle in the universe to go back the way it came, to reverse chemical changes, etc, and there's just no way that can happen

>possibility of time-travel
go park in a tight orbit around a black hole event horizon and enjoy your time travel into the future. Be careful though because there is no equivalent backwards in time path that you can take.

Backwards time travel is impossible for the reason mentioned; you don't move yourself; you unmove the entire universe .

That said forward time travel and time dilation exist just fine.

I've always wondered if futurists like michio Keku have considered the futurama approach to surviving the fate of the universe: not going back in time to avoid it, but using time dilation around an eternal black hole to power forward until quantum fluctuations have essentially sparked a new one. Also could "dark matter" just be invisible black holes on the far edge so space that have been surviving these soft resets of the universe?

so it depends on definition?

Pick two

How can energy break time and space?

Thats no sense at all since energy only affects matter.

The way a tine machine can be madsme by utiluzing planck physics.

No, dark matter is present in most galaxies. It's either particles we can't detect, or it has to do with the uniformity of spacetime, or the lack thereof.

>"Invisible black holes"
Well yeah, they all are

>eternal black hole
There is no scientific credibility to this statement.

>you unmove the entire universe
This isn't the reason it's impossible. You move forward in time just fine, despite "moving" the entire universe. The problem exists in our realization of the temporal dimension. We can't even hypothesize a way to travel backward in time because all the equations that describe spacetime are temporally symmetric (no difference in the direction of time).

However, we do know ways to move forward in time, or to accelerate that motion. Time dilation is the result of relative motion (in the case of gravitational dilation, this is because there is essentially no difference between a gravitational force and an acceleration in free space). By increasing your speed or acceleration, you can change your relative time.

The faster you move, the slower your time passes relative to outside observers. If you were somehow able to go faster than the speed of light, your time would move in the opposite direction relative to outside observers. This is the result of a singularity in the gamma coefficient at c. There are other reasons why you can't exceed the speed of light, and these delimit your ability to travel backwards in time. This isn't a complete explanation, and involves some technical fudging for the sake of explanation, but it contains the basic principles of the delineation of time.

>energy only affects matter
>how can energy break time and space?

How could you say these two things and not make the fucking connection

Good try

What if we unmoved just a little bit of universe?

Just orbit in the other direction.

Eternal black holes are credible; not even referring to the current lack of proof of Hawking radiation. It has been considered extremely difficult but mathematically possible to create a black hole and then interrupt its development such that it doesn't emit (if any of them do) Hawking radiation

That's not what I meant, I'm saying that nothing is eternal, not that black holes don't evaporate. And it's mathematically possible to do a lot of things, that doesn't mean they happen.

How little are we talking?

Regardless, everything in the universe is moving, so you have to take into consideration where everything else is. Like say you want to force the particles of your body back in time, well, the earth is moving
at godspeed in the opposite direction. So you better have a spacesuit. But then how do you deal with your particles likely being torn apart by gravity or air friction as your body moves at godspeed away from the planet?

Time travel to the past just isn't going to happen as we understand physics and the universe.

possibility of traveling back in time is nill.

Can't spell nill without ill.

As in our chances are physically ill. Why would we want to risk such an exchange of energy?

I want you to take a constant in your life user and try to put it in the configuration that you remembered it every day for 3 days. I want you to expect the same result. That the red, blue and green blocks can always be stacked back on top of each other. For 3 days. Taking these blocks 3 as a whole, then ask yourself. What is the equivilant of these blocks in our universe, what are the constants of the cosmos? Can they be stacked as I remembered them?
Then descend into the madness that is quantum theory.

futurism.com/new-research-shows-that-time-travel-is-mathematically-possible/ I read this recently, but it just a mathematical conception.

time travel does not exist. time is misunderstood by many

If the Arch-Wizards say it is possible, the Wizards must agree.
If the Wizards must agree so too must the Acolytes.

In summary. I want to leave this universe and explore :3

A black hole that doesn't evaporate is by definition eternal, though.

Who is going forward in time? Oh yeah, everybody.

Analemma

absolutely this, relativistic mass should die.
also you have no idea what you're talking about.
you're travelling through time now though

You're already time traveling
>in one direction
>at a constant rate

Dear fucking lord, look at what "science" has done to everyone.

There's no time. Time is not a dimension.
Time is a metric, motion compared to another motion.

"Time" isn't moving forward. Things are just moving and we measure that movement against other motions.

There is no time travel. The concept of a state of existence being held in infinite possibilities and states both in previous states of motion and future motions is not happening.

There is no dilation of "time" or "space" with light or black holes or whatever. Shit just moves.

Do we see the effects of time travellers on our current universe? No? Therefore time travel is impossible. QED

you fool, SERN is already at it

>time isn't an actual thing
This meme is old and you're a faggot.

the universe is either Determinist, and nothing you do can actually change anything. since everything is as it is, because of your time traveling. or you create a new parallel universe and can't change anything for your self and origin universe.

It's possible, you'd just have to rebuild the entire place to how it was in the past.

So technically, we're already capable of doing it, just to a limited extent.

You fool, those funds were obviously invested into a neat science fair detect'n'smasher for theoretical particles, not because they had actual goals to do something with it.
They attended Bilderberg 2017 just for the lulz and to read speculative forum comments
Titor out

you're always one breath of DMT away from doing so

I'm glad someone was listening

Gravity, higher dimensions, and "spooky" space (quantum entanglement) are our leads to teleportation and time travel. However, we must better understand and control these things before we can theoretically accomplish this.

The thought of orbiting a black hole in a ship until the universe dies and is reborn is fucking horrifying. As is the idea that "the far edge of space" is just a swarm of gargantuan black holes. I'm getting PTSD flashbacks of typing in random black holes in space engine and having the camera zoom into their event horizon really fucking fast.

TT is not possible. Moving through to positions through a space requires time or requires mass to already be there.

Time traveling CREATES mass at a certain time period which is impossible since mass cannot be created nor destroyed. To put this into perspective, lets figuratively say in 2k17 there are 200g of mass. But wait a second, you teleported from 2k30 to 2k17 so now out of no where, 2k17 has 220g of mass. See how you are creating mass out of the no where?

Since the begining of the universe and until the end, we will have the same mass thoughout and there is nothing that can change that, unless our fundemental properties of physics are wrong.

After enough red shift, photons and electromagnetic radiation become undetectable. So if there is a large enough void, expanding at the rate of the universe, that energy or mass will essentially be undetectable, or "dark"

>What's the real possibility of time-travel?

>time-travel

depends if you mean forward or backward travel trough time

and what happens when the universe die? did your black hole keep existing?
nothing is eternal

Yes, it does.

That's the entire point of eternal black holes you dunce.

Good thing that twenty years traveling at the speed of light is the same as twenty years here on earth. Your wisdom has solved some of sciences biggest mistakes. We can throw away everything we know and ignore history and time measurement

So time is just the process of entropy

Haha, now get of Veeky Forums

How big would a black hole need to be so that even when there's just vacuum energy left it still wouldn't evaporate?
