Time machine.

[mindless_moder]

A short documentary on the worlds first time machine. i cant even begin to imagine how light is able to bend space i thought it would require a great deal of energy, but apparently they've figured it out and i for one am glad that people are actually making headway in the field (if it s real...).

It's a real video, but don't expect too many wonders from it right now.

things like this don't excite me too much because i know i'll be long gone before these things even work in the slightest bit

Interesting. I don't know how bending and rotating space allows you to go into the past, or if light is even capable of doing that. I really ought to read up on this subject more, but to me this man seems like a crank. (I haven't read any articles about him at all. If what he was doing was a real possibility he would probably be getting much more attention than he actually is getting.)

I hate to strike down an idea that might actually work, so I think it is prudent to wait until the man actually constructs a prototype.

His name is Ronald Mallet he's a professor at the ?University of Connecticut.

Wait a minute, I just thought of another application. If this warps space, it might be possible to put a similar device onto spacecraft and create a "warp bubble" in front of and behind the ship, which would propel it to speeds faster than light. (this would unfortunatley probably kill everything on board and crush the spacecraft, but still, theoretically possible)

EDIT: reading through that article pretty much confirmed that the guy is a crank. He thinks that going back in time will take you into another universe, which is almost certainly untrue. He is also doing the experiment for purely irrational reasons.

 

[mindless_moder]

well what he was referring to was a possible solution to the grandfather paradox.alternate universes are a distinct possibility so it wouldn't really be that much of a stretch to suggest that time travel is really the exploration of different dimensions. also why are his reasons irrational :S ?.

This guy is an absolute fruitcake, and he's talking out of his batty crease.

By bending or warping time, all you are affecting is time perception. You can not alter or perceive events in the past or future - You can not send particles to the past or future. These particles would experience a week more time, instead of being sent a week to the past or future. The act of actually sending particles to the past from the future would itself be a means of communicating, and it opens up so many stupidly bizarre and unexplainable loopholes. Einstein's probably rolling around his grave pissing himself.

you can actually travel into the future if you travel at the speed of light. since the speed of light is a constant some other property has to change in order for it to remain so under any given circumstance those other two properties are space and time. as you approach the speed of light time slows down. so it progresses slower for you and faster for the people on earth so when you get back you're in the future because everyone else has aged and progressed normally.

based on what exactly ?. healthy skepticism is well.....healthy but calling it BS is taking it too far.

 

[Ennui]

Moder, that's still not really time travel. Pobz is right. Changing the subjective passage of time can be achieved, but you can't actually go back in time or forward in it... it still passes forward no matter what.

 

[mindless_moder]

well it is in a sense because your more or less the same person while everything around you has progressed to the future. granted it isn't time travel in the sense of having the liberty to move in and out of specific frames of time but it is time travel.
as for what the professor describes, it has to do with the universes predicted by string theory he sees every frame of time as existing in different universes. I'm not completely informed on the theory behind his time machine but i wouldn't be so quick to shoot it down he obviously knows what he's dealing with.

If proper time travel was actually possible we'd know about it because we'd get visitors from the future.

well thats the point right ? we haven't set up the machine yet so they cant come back to our frame of time ..yet.

I presumed in the future they would have their own time travel machines that traveled back in time with them.

 

[mindless_moder]

even if they had something like that they would only be able to travel back to areas that had the machine running.
