[QUOTE="Penguinchow"][QUOTE="BumFluff122"]That's the newest theory.

Where would the matter needed for the time machine come from otherwise?

The 11th dimension.

Seriously though what does that have to do with it?

It has everything to do with it. The law of conservation of mass and energy. No new energy or mass can be created, so the mass would have to come from somewhere.

Why does one need matter to build a time machine? There are forces in the universe, some we know and some we don't, that are perfectly capable, if time travel is possible, to use to travel through time.

i saw some show with a guy saying it was theoretically possible to pass information in the form of particles from the present into the past... not travel to the past per-se ( bttf style ) but basically send matter to the past somehow..

Well whatever you send to the past is going to consist of matter. That matter is going to have to come from somewhere. Note that I am talking about traveling back in time not fowards

Well the mass wouldn't be created, it would just move from one time to another. The law of conservation of mass and energy doesn't keep one from redistributing mass and energy.

That matter would more than likely come from the present. With your previous statement that matter in the universe is constant and can not change, quantum mechanics states otherwise.

Well the mass wouldn't be created, it would just move from one time to another. The law of conservation of mass and energy doesn't keep one from redistributing mass and energy.

If you traveled back, say 400 years, the mass that is now used in your body would be scattered about used for other purposes would it not? I suppose the real question is does the constant amount of mass and energy exist outside of the constraints of time?

Its the conservation of mass AND energy. True the level off mass is not constant but the levels of mass and energy combined are. Quantum mechanics says mass and energy are interchangeable does it not?

I don't see how that's relevant. It would result in an increase of matter in the past, with an equal DECREASE of matter in the present. No net loss or gain.

This law only applies for closed systems. The thing is, if it is possible for one to go back in time, then we have to stop looking at "the present" as a closed system. It would be an open system, and such systems allow the redistribution of matter and energy.

I don't know you'd have to ask someone else more famililar with quantum mechanics. But if pastwward time travel is possible then we don't knwo as much about time as we think we do. Why can;t this law work through time rathe rthan just through space? If an object is sent to the past it would still exist within time.
