if time travel is real, has it already been invented?

Question

then everything would already been done?

Answer 1

If time travel were possible, you would have met someone from the future or heard of someone from the future going back in time. If there were a time machine in the future EVENTUALLY in the million years in the future, some bad guy would bring back a future weapon and attempt to take over us backwards people LOL. It hasn't happened so....

Time travel is not possible because the second you went BACK in time before you were born you wouldn't be born, therefore you weren't alive to go back in time! In theory, the second you went back you would automatically change the future changing the even that sent you back in time, making it impossible.

Let's say you go back in time. You just take a walk in the country. A butterfly flies up to you and then turns right rather than hitting you in the head. That butterfly was supposed to go straight and be eaten by a bird. Now that butterfly isn't there so the bird looks elsewhere for food where it wouldn't have been. Then the bird flies by a cabin looking for food and a kid sees it and thinks it's beautiful and decides to paint a bird rather than go fishing. In the other timeline that kid went fishing. Now because you changed the flight of the butterfly this kid is painting a bird. His gramma says she loves the painting of the butterfly and begins to encourage his painting and he becomes a somewhat famous painter. He was supposed to become a factory mgr where he once saved the life of a young man....

I like your question if time travel were possible, wouldn't everything be done. You'd think huh, if you could go as far ahead in time as you wanted. Maybe that's another reason why it's not possible.

I do like the movie "Time Machine" with Samantha Mumba. I hated the Michael J. Fox time travel movies, "Back to the Future."

Answer 2

Time travel into the future is pretty easy - I've been doing that ever since I was born and will continue to do so until I die - obviously really.

If you mean travel into the past (which I'm sure you do) it cannot happen due to the law of thermodynamics which states "Entropy must always increase" which basically means that hot always flows to cold and can't happen the other way round. Obviously really can you imagine adding Ice to your Tea to get it back to boiling as opposed to watching it melt?

So no time travel is not real and therefore it can't have already been invented because it is impossible. It has nothing to do with observed differences in time based on relativity (time is just different for the observer and the particle it's not going backwards) and no-one can travel even "1 second" into the future because by the time they get there... it's the present.

Answer 3

Time travel has already happened......

Today, the only way to "travel" to the future cannot be used to travel over long periods of time -- only less than a single second. It is so insignificant that it is usually not mentioned at all. And the only people that have used this method have been astronauts. Basically, the longer a person is in orbit around the Earth, the younger the astronaut will be in relation to observers on Earth. So far, the record for traveling farthest in the future using this method is held by Sergei Avdeyev[4]. He was in orbit 748 days (total) and traveling approximately 17,000 mph, resulting in him traveling 0.02 seconds (20 milliseconds) into the future[14]. That means that for Sergei Avdeyev to time travel just one whole second into the future, he would need to orbit for approximately 102.47 years. A common misconception was that the Apollo astronauts traveled faster, so they held the record -- they did travel faster, but not long enough (only a few days).

Answer 4

In order to talk about time and travel distance it is necessary to underdstand the dual nature of time. It can dilate or shrink as Einstein tried to communicate to us.

It is a quantity that indicates how fast a process takes place as well as the direction the process is moving.

If you measure time as a cyclic rotation as the earth acting as a pendulum you will observe that it describes a forward motion and then reverses the motion. So In the forward motion of the Sun ,the time moves forward(shrinks) and when the earth swings in the oppposite direction of the Sun time moves backward(it dilates)Relativity if well understood is really simple.

Answer 5

what do you mean by time travel is real
time travel is possible
any thing that can go faster than the speed of light is not yet invented,but soon it will be

Answer 6

I think aliens are actually humans from the future who got accidentally "busted" and their spacecraft is actually a time machine, not sure why they are so anally fixated with the probes and all, looking for ancient corn maybe? Maybe they come down to fix the present to prevent a terrible future ala 'back to the future', maybe Bush can choke on a pretzel again.

Answer 7

If time travel follows string theory, then what filament of time was followed? Would you go back to find that Hitler won WWII or Al Queda won the Nobel peace prize?

Answer 8

Yes...time travel happens all the time in quantum physics.

Time travel for people is another story.

Answer 9

It is real but not invented.

It is only in theory so far. The catch is that You can't go backwards only forward in time.

Answer 10

It is invented already ofcourse otherwise we wouldnt know the word time-travel.
But we do not know if it is real.
