How fast (in Mph) do you have to be to go into the future?

Question

Is it possible to go to that speed?
If so, will you see yourself in the future?
I am just curious :)

Answer 1

Well, it's a little more complicated than that.... but, here's the gist:



When you go faster, time for you *slows down.* So, someone who's stationary, say, you're twin brother on the Earth, will age at a speed everyone here is used to. But, you get on a spacecraft and head off to, say, Alpha Centauri. As you go faster and faster, and get closer to the speed of light, time for you begins to pass more slowly. *YOU* don't know it, really - you look at your watch, and it's ticking along like normal; but, you get to Alpha Centauri, take a few pics, then come back to Earth. Say along the way your speed increases to 90% of the speed of light.



Finally, you arrive back on Earth, after a long journey... As you see it, you've been on that spaceship for almost 29 years. But, when you step out of the ship, and expect to see your now 29-years-older twin brother greeting you, instead it's his grandson - and he's middle aged. While 29 years have passed for you, about 85 years has passed for people of Earth.



Because you gradually built up speed to 90% of the speed of light, (and then slowed down when you got close to your destinations), time for you passed slower than those who were stationary on the Earth... You haven't really skipped into the future, but to you it may seem like it... what happened was time for you slowed down, and the future got here faster (by your view...)

Answer 2

If it is possible or not is still up for debate, the problem is we would need to be going at or above the speed of light. There are huge problems in reaching that speed. It would take close to an infinite amount of energy to accelerate any use full mass to that speed.

the speed would be 670 616 629 mph



(unless of course you have a Delorean and a flux capacitor, then 88mph is all you need)

Answer 3

I assume you mean faster than the basic rate of time's progression, that would come out to be >0 mph. Even at slow speeds time is distorted, but the effect is so tiny it would be useless to measure (now that i said this watch the government sponsor a $100 million experiment to see how much time is distorted at an average walking speed).

Answer 4

0 mph, you already are going into the future, but if you wanted to go further into the future at a higher speed you are already going, which is 1 second per second, you would need to go at a negative speed, which is impossible.

Answer 5

Zero. You are going into the future at the rate of 1 second per second. The faster you go, the slower time passes - for you. For everyone else it stays the same.

Answer 6

i know what you mean, but how do you figure you could see yourself?? there is only one you. there seems to be like two types of time travel 1. fast forward and rewind version( eg the time machine) and 2. chronological displacement (eg back to the future), while forward time travelling is theoretically possible but backwards time travel is theoretically impossible. it doesnt work as you think it works, basically you travel so fast to and from the earth, i dont know the physics details, but when you come to stop back on earth you have appeared to age less than everyone on earth. somthin to do with space-time compression or spatial skipping or somthin???

no you could not see yourself in the the future..... actually ... no dont think thated work

Answer 7

On a round trip which begins and ends on Earth, time will pass more slowly for you, by a factor of

1 / sqrt(1 - v^2/c^2)

where v is your speed, and c is the speed of light.

Answer 8

at speed of light. nobody can reach this speed. and yes we could see ourself in the future but older.

Answer 9

in case you pick to run 2.41km in 12:1/2-hour, you want to run at: (60min / 12 and a 1/2 min) x 2.41km = 11.568km/h For 10:30min its: (60min / 10 and a 1/2 min) x 2.41km = 13.771km/h

Answer 10

to travel future beyond we should travel in the speed of light. we can attain a speed of 99.99% the speed of the light.the speed of light is 670616629 mph.if you travel in this speed for one week you will be actually reaching ONE year .

Answer 11

You don't have to be moving at all to go into the future. Every nanosecond you move further into the future.

Answer 12

88 mph

Answer 13

10000000000000mph, and a rocket cant even go that fast .. haha sorry (:
