I want to make a time machine. Any ideas how I would go about it?

Answer 1

You want to make a clock?

Can't you just buy one at a jewellers?

Answer 2

Kip Thorne has postulated such a machine, but no one has built one for reasons that will be obvious.

First of all, you need a flat region of space. Space is flat when there is no mass to distort it, so you are going to have to be far away from any stars.

Second, you need a hollow tube built of the matter that makes up neutron stars.

Third, you need something really heavy, such as a small asteroid, to which one end of the hollow tube will be gravitationally attracted.

Now, tether your asteroid to a really fast ship capable of going some real percentage of the speed of light, say .4c. Start traveling in a circle, dragging the asteroid behind you. The one end of the neutron tube will follow you.

Because an object in motion experiences a Lorenz contraction in time, the time at the end that is following you will travel slower than the other end. Eventually the two ends will have a noticeable time difference, with the stable end being farther in the future than the end that has been moving. Let's say that you arrange it so that the moving end is now one hour in the past than the stationary end.

Now drag the moving end so that it is near the end that was stationary.

If you now take your ship (release the asteroid--you're done with it) and enter the stationary end at 2:00, you will shortly emerge from the end that moved at 1:00. You could then transit back to the stationary end, go through again, and be another hour earlier.

One limitation to this is that it is impossible to travel back in time before the existence of the tunnel.

Answer 3

Well ok, I'll tell you but you won't like it.

First, I'm telling you know that you have already failed. If you are successful in biulding a time machine in the future, your future self should be able to come back to a time of your choice and pick your present self up now for a ride. But since you are asking this question, I'm guessing you have not met your future self, and thus will not be successful in biulding your time machine.

But if you want to be bull-headed and try to biuld one anyway, here is the basic formula:

AB = DxT>C
Thats from point A to point B must equal Distance times Time which has to be greater than the speed of light (C).

In order to perform this, you must find an object with a VERY large mass. The larger the mass the better. Of course, a black hole has infinite mass so it would be the best to use, but I bet you don't have a black hole handy do you? Instead use a medium sized star like the sun.

Biuld a spaceship that can travel at near light speeds. You don't need to go the speed of light, but the closer the better. I recommend using a "Scramjet Engine" just recently invented and tested at NASA. Sure, it has very slow acceleration, but after several trips around the earth in order that small acceleration biulds up to a VERY high top speed.

Ok now so far you are in your spaceship traveling at near lightspeed orbiting Earth. you will notice that time has slowed down quite considerably. If you could see a clock outside your ship it would not appear to be counting time, but it is, just very slowly. While inside your ship time is progressing normally.

Now, fly your ship directly at the sun. DO NOT HIT IT! Instead, get as close as you safely can, but slingshop around it. The added gravity from the sun will push you beyond the lightspeed barrier. (I know this breaks some laws of physics....but don't worry about it, as long as you can counteract the enteria, you will succeed.)

Congratulations, you have done it. Now return to Earth. Depending on the amount of time it took you to perform the slingshot, the farther forward in time you will have advanced. About 15 seconds in orbit around the sun at faster then light speed should account for 50 years going by on Earth.

If you want to travel BACKWARDS in time, just do the same thing as above but make sure your orbit BREAKS the light barrier rather than just matches it. Same 15s:50yr estimate applies.

OH by the way. The Earth is destroyed by a comit in 2036......sorry.

Answer 4

It's real easy. A jar of water, two tubes go in through an air-tight lid. One tube goes into the water; the other end connects to a tube with smoldering herbs. The other tube ends above water, and you suck on it with your mouth. Allows you traverse time, space and parallel dimenstions.

Answer 5

Assuming that a time machine is possible , wouldn't we have encountered a few time travelers from time to time? Why waste your time?

Answer 6

Yes, go learn String Theory

Answer 7

I think time travel is not posible, But If you insist, there was a good movie a couple of years ago, the name scapes me.

Answer 8

well you have to go to the future 50 years from now to find out....

Answer 9

Go to England and contact Dr. Who. If your lucky he'll tell you how he built his!

Answer 10

wow that's a hard one. I doubt you are going to find the answer that here.
