When you look up into the stars at night, or look deep into the sky you are staring at someone looking at you through a telescope

it's not time travel, merely faster than light travel.
By traveling instantaneously you have managed to reach your destination faster than light can reach it, so being a million light years away, you would be seeing light that left earth 1 million years ago, but you would still exist at the same time that you left. The same way that when we look out at stars we are seeing basically a delayed feed. I like to think of human vision as a bit of a delayed live feed, with the delay depending on the distance between yourself and the broadcaster (source of the light entering your eyeballs)

if you had an incredible telescope that could see living things on the earth, would you be able to see things movng around? would you be able to rewatch history?

>>19045585
yes

Orson Scott Card wrote a book I read as a child that dealt with rewatching history. I believe it is called Pastwatch. Good read. I'm sure you could easily find a .pdf online with a google search.

Thanks for that. Wish there wasn't op's like OP on /X/.

>instantly

doesn't work that way, spacetime is relative which means you can't 'instantly' do anything - you would have to actually travel there, but even if you traveled 'faster' than the speed of light by creating a warp field (i think some scientists admit it may be possible) about 10x the speed of light it would still take about 5 years to get 50 ly away, when you looked back you would see things that happened 45 years ago. So let's say you use a warp drive today and travel 50 ly away and you use a powerful telescope to observe earth: you'd see the 1970s, but that requires a crazy powerful telescope and the further you go the more powerful your telescope would have to be. Presumably if you got 100 ly away in ten years using your drive you'd see the world circa 1927, Yeah i guess there could be a whole team of archaeologists just traveling this way further and further back to see everything as it happens, but again, they'd need insane telescope tech.

Actually thoughtful and informative answers in this thread so far. Really impressed.

Although it's only a matter of time before some retard kicks down the door and says something about astral projection or whatever

>travel a million light years away and look at Earth
that's backwards time travel. You would see an ancient Earth

now,
>returning from a million light years away
it would be a couple million years in the future, providing it's done instantaneously.

Jesus, it is a hyphothetical scenario. Just entertain the thought experiment. Everybody knows that instant teleportation isnt a thing you sperg

What if it ends up being exactly the same as things are now?

>>19045538

>would that be considered time travel?

Yup.

Mindfuck comes when you add layers

OP you can just astral project out into space and make an astral telescope while in the astral plane (it is easier to make high tech because there are less rules) that links to the material world. Then you could point it at the earth and see everything.

What is magnetic reconnection for $5000, Alex.

not an example for instant teleportation

>he hasn't converted matter to frequency yet

>>19045538
Yea you could see the world as it was 1 million years ago but with our current tech from that distance it'd just look like a blurry blue spec.

frequency of what?

>Google particle wave duality
>shit brix

what if everything we see right now is the past because the world ended millions of years ago and we are the cosmic dust flying through the universe.

>>19045538
No it's not time travel. You would be seeing the past not living in it, just like now when you look at the stars. And yes you would see dinosaurs.

>>19045538
Also you might experience time dilation, which means time flows differently depending on your speed and the gravitational force you're experiencing. If you stay on certain planets for a couple of hours, years will have gone by on earth.
