Is a time machine possible?
    #2131314 - 11/23/03 11:23 PM (13 years, 17 days ago)

A question posed to us from the days of our childhood.

Nonetheless, always lingering in the back of our minds. Is this possible? Why or why not?

No.

Well what do you mean by a time machine specifically? I guess a spaceship that could travel nearly the speed of light could be considered a time machine. There is the Twin Paradox. So lets say you get into the ship, travel at 3/5C for 8 years. You will have lived 8 years, while earth would have gone through 10 years. I guess that technically would be travelling 2 years into the future.

As for a time machine like in Back to the Future, I'm going to have to say no. You can't travel back before the time machine was built. And you can't travel forward in time because I don't believe in destiny and nothing is preset.

There are TOEs (theorys of everything) in modern physics that allow for wormholes that would tie together different parts of space/time. This could, in theory, allow a person or machine to travel from one point in time to another via these tears in the fabric of the universe. However, building a machine that could actually accomplish this is another story altogether as it would have to be able to withstand forces of gravity comparable to those of a black hole, as well as overcome many other physical and even philosophical impossiblilties. So for all practical purposes, no. And it is only an untested theory anyway.

You science teacher was wrong to present a hypothesis as fact...
Good eye cathing the mistake.  :smile:

> would have to be able to withstand forces of gravity comparable to those of a black hole

Recent computer models of certain black holes indicate that there are areas of low gravity which might be possible to survive within.  Of course, computer models aren't 100% accurate...

Well, modern physics doesn't exactly rule out the possibility of time travel...but it remains that: only a possibility. In all likelyhood the energies required are far beyond anything human beings will ever achieve.

I do not think time travel will ever be discovered by humans, or at least not as long as our consciousness is structured the way it is with respect to time.

Evidence? Well do you see any time travellers here? If time travel is invented sometime in the future, it stands to reason that someone, in all the future, would come back to a time before now. It also stands to reason that eventually someone would slip up and we would learn of time travel. We haven't :smirk:

Like a splinter in your mind...
Driving you mad.

One of the interesting theories of time travel that I have read states that time travel can only occur back as far as the invention of the time machine.

The infinite parallel universes theory along with time travel would indicate that the likelyhood of a timetraveler ending up in your timeline would be very small.

How to Build a Time Machine
It wouldn't be easy, but it might be possible

the concept of time is based around nature and this planet aswell as the universe, but time itself is man made. how do you consider you will go back in time or forward in time? i think its possible, but with the help of certain substances. i have traveled to different realms of worlds i never imagined before on lsd, but thats not necessarily time travel as it is mind expansion into the unknown.

i dont think no object is gonna rocket you from this time to the next.

screw the flux capacitor id rather have one of those hover skateboards!

Well time is more of a place than a thing, so just imagine traveling from place X to place Y. This could just as easily be going from 1pm to 3pm, it just working out how to go back. But even if you did have a time machine you would probably not only travel through time but also into a diffrent universe. As there is more than just x,y,Z and T time co-ordinates, there is probably r,e,w,y,u,i,j,h,b,v,s, as well.

I don't know...it seems to me that time travel would involve "rewinding" all the Entropy of the entire universe, and would require unimaginable power. Just my .02! :smile:

time travel is possible, one needs a way to create a vast area of space with negative energy density, a way to increase the dilation of a wormhole of the quantum foam background and keep it open, and a vessel with these same abilities. then a person can travel vast distances in a period of time that would be equivalent to ftl if moving linearly. also, cp and t symmetry allow for time travel on the microscopic scale, which allows for the possiblity of time travel, however leaving open the possibility that it would take impossibly large amounts of energy to produce such an effect on a macroscopic scale

time loops cause a problem however, in a universe or area of the universe with negative energy density, one might find themselves attemtping time travel using the cp and t symmetry of particle pairs but find themselves on an infinte time loop. this would pose a problem. FTL data transmission may be possible in some way. if the two members of a virtual particle pair, for example the elctron pair in a orbit, were seperated, and one of the two's spin was changed, the other member of the pair would immediately change to fulfill the pauli exclusion principle, no matter how far appart the two are. If one were say in alpha centauri and the other in california, it would be instantaneous.
