Warp and Time travel

[Guest BH King]

It is possible to achieve a sort of time travel, first you will have to be travelling at, or close to the speed of light and for instance, say you wanted to travel to the andromeda Galaxy, the pilot, or crew would age 28 years travelling there and 28 years back as well and in the mean time the earth has aged 400,000 years!:zzz:

If you mean "would this difference in experience happen", then yes it would in theory.

 

The problem is actually getting a ship to lightspeed, and being able to safely carry humans on it.

yep.. that's when cryogenics come in handy..

Huzzah!!!!

 

Now we have to perfect three technologies.

In order to age 28 years in 400,000 years local time, you'd have to go 99.999999755% of the speed of light. I suspect by the time we have a form of propulsion (anything we've got now, even antimatter, won't cut it), we wouldn't need to travel in a straight line.

have you thought about the twins paradox?

We use gigawatts of energy at CERN to accelerate protons to near the speed of light. These aren't even atoms and are an almost undetectable amount of mass. Imagine then what kind of energy would be needed on our scale to accelerate a pinhead.

We have to consider tons of mass.

If you stayed extremely close to the even horizon of a black hole you'd age slower also.

[aman]

That takes an enourmous amount of energy also. Easy energy is the key.

You'd come to a point where time is nearly stopped, not sure if it would ever completely stop. You could watch stars be born and die in the blink of an eye.

[fafalone]

The problem with that theory is this paradox: if time slowed down enough, you could see the end of the universe; but you cannot end if you're not participating in the flow of time; so what would you see after the universe ended? furthermore how could a black hole end if time was stopped, since it is in fact composed of matter.

It seems as the story of humanity unfolds that if we can imagine doing it, we will find a way to do it. Our record so far seems to be getting better at supporting this. I feel the energy barrier is close and big clues will come when the CERN upgrades are finished in about 2 years.

Well here's the way i theorise a possible time travel. In theory there is a "MEDIUM" where normal space and hyperspace are. If some type of explosion may fracture this border line. If this is possible then we can theorise that the speed in witch the matter of our human bodys will travel at a much faster rate. Also in my theory, the time in hyperspace is completly seperate to the time of normal space. The only thing rquired would be a enormas, spacial distortion particle.

[Cap'n Refsmmat]

The problem is, you're assuming that there's such a thing as hyperspace, and that there is a tangible border between it and our current "normal space."

Another possibility is to circle a rotating black hole following specific course.

 

If you do it right you will arrive back at your point of departure at the same time you left.
