How can time travel work if earth is moving?

If you went 1 year back in time you would end up in the middle of space because the earth and solar system and galaxy are all moving super fast. If you went 10 seconds back in time you would either be buried hundreds of feet underground or hundreds of feet above earth. So time travel in movies makes no sense.How can time travel work if earth is moving?Well, as others have stated, you can make up your own rules in the world of fiction.



The concept of disappearing in one time and reappearing in another has its flaws as well... conservation of matter/energy comes to mind. I mean, if time travel in that sense were possible, what would stop you from putting the entire Earth in the time machine (well, aside from the fact that the Earth is probably larger than the machine itself) and sending the whole thing 1000 years into the past. With two Earth's in the past, you could really cause some problems. From the perspective of someone in the past, 1 Earth mass was instantaneously added to the universe. It wasn't converted from energy, it just materialized.



The type of time travel that isn't inhibited by the laws of physics, is more aptly referred to as time dilation. In relativistic scenarios, an observer in a different reference frame will observe you aging more slowly, they will see your clock tick more slowly. To them, they see that time has slowed down for you.



The problems with this, however, is that you would have to change direction to get back to Earth, which would negate the time dilation. One way to think of it is, the farther away someone is from you, the longer ago they appear to be. If they are constantly moving away from you, they appear to constantly age slowly. Of course, in their frame of reference, time is ticking away as normal.How can time travel work if earth is moving?
According to Eisenstein special theory of relativity time travel is relative.... Read the twin paradox below.



One 25 year old twin stays on earth while the other, fresh out of astronaut school, sets off on a space voyage travelling at 90% of the speed of light. After 10 years in space, with her mission accomplished, she turns round and heads back to earth. By the time she lands she knows from her on-board clock that 20 years have passed. She is now 45 years old. Fortunately, her study of relativity has prepared her for the shock when she sees her twin sister, who is now 71 years old.



Conclusion: Space travel, when it is really, really fast, is also time travel: you travel into the future without getting that much older yourself.





Though I'm not totally sold on Einsteins stuffHow can time travel work if earth is moving?There are plenty of other reasons why time travel does not make sense.



However, the one you invoke could be worked around if you make the following supposition:



A time machine cannot go to a time before the machine was turned on. Once the machine is turned on, it keeps track of its location (space and time) because that is the only way it can find its way to an exact "space-time" spot.



Of course, this implies that no one can travel back in time to visit us, until such time as we actually invent a time machine.

Personally, I think that even with such a device, a time machine cannot exist. There are other (more severe) problems with causality.
That isn't how it works at all! For one thing, actual time travel that is noticeable has never been done, some even say its impossible. That's wrong though, in order to time travel, you would have to be going faster than the speed of light, you could do this around a celestial object with high mass (i.e. the sun) or you could do that in a straight line, if you choose to travel faster than the speed of light around the sun (as seen in Star Trek), the force of gravity would keep you in our solar system, if you choose to go faster than the speed of light in a straight line, you will appear maybe even light years away, but you will be able to get back simply by going the speed of light again, and even if you somehow "controlled the 4th dimension" you would still be kept in our solar system by the gravity of our sun, which stretches across our whole solar system, creating the heliosphere, but even outside of the solar system, the solar system isn't going to be "rushing by you" as you would be moving around the black hole in the center of our galaxy (Sagittarius A* (pronounced A star)) and therefore would be traveling with our solar system, also, you would not "appear buried hundreds of feet underground" unless you were stupid enough to point your spacecraft at a celestial body!How can time travel work if earth is moving?In the movie, if they have gone as far as to make a time machine, isn't it possible they added a teleportation function, with calculations that automatically positions them in the location on earth that relates to the point on earth in the present? Time travel can be considered a an advanced form of teleportation itself, as you are technically teleporting through time.How can time travel work if earth is moving?
Movies don't have to mimic reality. Movies are like the "what if's" of reality. Plus it's fun to watch Back to the Future, don't you think? I mean wouldn't you like to know how it'd be like to go back in time? Would your actions change the future? However, in reality time travel to past is impossible so your arguments are irrelevant. Why don't you talk about time traveling into the future? It's been done before, is currently being done and will be done in the future.
No it doesn't that's why they are FAKE everything doesn't make sense like the movie UP he's about 5 and his hero is lik 40 and when the five year sees his hero they are the same age pretty freaking dumb it's a fact people know more about space then the what's in the ocean idk weird stuffHow can time travel work if earth is moving?
That's of course assuming that the space-time continuum is either the space OR time continuum, which kinda flies in the face of physics. But if your model is smarter than that then whatever. Otherwise, your question is kind of like asking "what happens if I get eaten by giant cucumbers?!"
Theoretically, the speed of light is as fast as anything can travel, however, if you were able to move faster than that, depending on how much faster than the speed of light you travel, the farther into the future you would travel. of course you have to be moving away from earth
You attack the question as if time travel is physical travel, which it is not. If time travel were possible you would stay in the same physical location but observe what happens in the future or happened in the past at the position you currently occupy. Got it?
Indeed, backwards time travel is impossible. However, all things move forward through time, all the time.

yep.... I agree.... the calculations to get a person to a point in time, either forward or backwards, are immense.... and would have to be spot on, lest they appear inside a wall or out in space....
I actually wrote a science fiction short story that used that fact as a plot device, with the time traveler ending up marooned in deep space (he was a baddie, so no real harm...)
time travel is just fictional. its never been performed (successfully) in real life
"So time travel in movies makes no sense."



FYI, movies are fiction.
You need a temporal GPS in order to track your location based on time from your home base.
That isn't how it works.
