Surely all those alternate realities would cause even God's CPU to overheat.

How does one overCLOCK a TIME machine?

He has a multi-core processor. One for each reality.

So when you time travel you don't just make a new reality, but a new core as well?

Getting back on track... sort of... if going back in time makes a new reality then how come we happen to be in the one "original" or "true" reality? Isn't that reminiscent of the old "earth is the centre of the universe" theory?

Also, if time travel creates alternate realities then a time travel machine that works would result in the traveller disappearing and never, ever returning (to that reality) which would mean it would be indistinguishable from a machine that just vaporises anyone stupid enough to get in it. That would make it kind of difficult to test.

It also partitions his hard drive, but thats a whole other discussion...

Or it could be said that this universe is the center of our reality.

Not really, in any reaction no matter is created or destroyed. This is a fundamental law of physics. A through examination of the machine would show that all the matter in the traver's body either was converted to another state (destroyed) or is not there anymore (sent to another reality).

I'm not sure what you mean.
If time travel is possible and it creates new realities then every time something travels through time a reality is created in which something or someone just popped into existence. How come we're not in one of those realities? Do we just happen to be in the "original" reality?

My use of the word "vaporised" was... let's call it artistic license. The point is that you wouldn't know where it went or what state it arrived in. All you'd know is that it disappeared. You could say "I made a machine that makes things disappear! REALLY disappear!" and someone would probably give you a physics prize, but I bet you couldn't persuade anyone to get in and go for a ride. Even if you could, you'd still have no idea whether you'd made a time travel machine or just a "vaporizer".

With out knowing that a time travel event occurred they we can't know.

Well you are assuming that someone just tossed a bunch of parts together and declared it a time machine. How to construct a time machine is actually know, but insanely difficult to do- it involves wormholes, black holes and near light speed velocities. In such a case matter can travel both ways though a wormhole allowing the traveler to return and confirm the trip.

Mass is "destroyed" or "created" all the time producing or expending equivalent amounts of energy. E=mc² and all that. It's the sum of mass and energy that remains constant. Atomic bomb anyone? BUT in systems where you don't have nuclear reactions or sub atomic particle """transformations""" mass is preserved ... pending further investigation

But mass is not matter. You can add mass by increasing speed but the matter in an object does not increase.
