How would time dilation be if you were to instantly teleport from point A to point B?

your speed would be infinite so time dilation would be infinite.

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

Well what does that mean? And is your speed infinite? Let's say you teleported 1m, and I teleported 2m, who is faster? And can we really calculate it? Because the time is 0 and we can't divide by 0.

And there's your problem. You're trying to apply certain laws of physics to something those laws weren't designed for or don't work for. Time dilation happens for moving objects. Teleportation in the definition of instantly transporting between two places isn't moving, it's teleporting.

It is moving!,as long as you move from one place to another you still move.

"Instant" teleportation聽 is not really instant,but a relative thing.

For example if a human teleports聽from point A to point B in 0.1聽seconds the human will perceive it as instant while聽it really is not.

That's assuming teleporting will take time.Instant teleportation is instant teleportation, or it will just be not-instant teleportation. Of course in reality we don't know what it'll be like if it's even ever possible.

Even if it would take some time, you would still be stuck with the fact that you disappear at one spot an reappear at another and will have a hard time creating a reference frame for that.

Nothing, this is a meaningless question because it's impossible to teleport.

Speed is distance over time. Distance in this case would be a meter or two. Time would be 0. You tell me what the speed is.

We can't, both speeds would be infinite which isn't a thing that is allowed in our universe - at least as far as we know.

@tikker

If your speed is infinite - Time will be infinite as well.

So moving at infinite speed,for an infinite amount of聽time - You might as well say that it doesn't exist since you will never reach the destination with those numbers.

That is true, infinities are always nasty. This is just replacing one problem (teleportation) with another (infinities) though. I think the devil is (as usual) in the details.

Velocity is defined as a change of position with respect to time: v = dx / dt. If you move from x1 to x2 instantly, your velocity will be indeed be infinite (well technically undefined, because we can't divide by zero). On the other hand, what happens if teleportation does indeed take like 0.1 ms? Let's stick to the definition of teleporting as the "transfer of matter or energy from one point to another without traversing the physical space between them". The problem that now arises is that dx/dt is undefined because there is no dx that is travelled in the time interval dt, hence your velocity is still undefined/infinite. We only know that x(t=0ms) = <position A> and x(t=0.1ms) = <position B>. Anything in between doesn't exist, because you are not at any of those positions in that time interval. So I think you cannot define a proper "speed of teleportation" anyway, because the math doesn't work out.

Interestingly there would be the point of conservation of momentum etc. to think about:

https://worldbuilding.stackexchange.com/questions/144215/velocity-difference-from-teleportation

https://worldbuilding.stackexchange.com/questions/131575/teleportation-keeping-momentum-on-arrival

making teleportation over great distances potentially rather dangerous.

Yep,that definition is impossible.

The closest thing to it is taking an object and convert it to something that can be transferred really fast - like a laser light in an optic fiber cable.

That way the object is travelling as light,then at聽the destination it's converted back to it's original shape.

That's kind of the point of it no 馃槢聽 We don't know of anything currently that will ever allow teleportation.

Not sure what would be easier. Inventing teleportation, or inventing a way to build stuff form light.

Well,energy can be converted to other types of energy - and light is a type of energy.

So by conversion of different types of energy we can make things,for example we take electricity convert it to light and then we get a picture on a computer monitor.

We can also convert it to heat,convert the heat to movement by heat and convert that movement to electricity again.

While pictures are not originally an energy - We managed to take energy and聽build a picture with it.

There is potential here.

Sure I can see the potential, but using electricity to show a picture on a monitor is still miles away from actually manufacturing that actual picture from light and far from teleporting something. We're not talking light to heat or electricity here, but converting your atoms to light and vice versa on the other end. For teleporting inanimate objects we have the benefit that a copy will likely do, if we can accept the philosphical problem the ship of Theseus, aka faxing. But even if we conquer the laws of physics and do manage to teleport something, teleporting living things will probably still be in another league.

No.

Faxing is producing an electronic representation of an image of the surface of paper聽and sending that via phone lines to a printer where it's decoded and used to reproduce that image onto the paper using聽toner.

The original stays in place, and the replacement is only a visual representation of the original.

I was asking if it meant the time would be slower or faster for the one who teleported. Why do you think it is impossible?聽

Also if I am not wrong time dilation wouldn't exist because as far as I know it is a matter of acceleration, and you are not聽accelerating in this case, even if it is a case of speed, again, your speed is 0.

Looking at the equation for time dilation given here http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/tdil.html

The Lorentz factor would be sqrt(-infinity), which means you're dividing time by imaginary infinity. WolframAlpha tells me that's 0 for anything where time is finite.

So no time dilation?

Time dilation most certainly exists. What I'm saying is that for teleportation our math breaks down, so either it doesn't happen (since you aren't moving with respect to something else) or other weird stuff happens.
