# Thread: Faster than light travel/Space & Time theory

1. Hi,

Please read below. I am dying to find out if this has any truth in it!

I haven't had much official education of Science. However, I do like to learn as I go.

The other day me and my brother had just finished watching the episode of Stargate SG-1 when one of the SG teams gets stuck on a planet because there is a Black Hole just outside of orbit.

We started discussing black holes etc. and how they work (my brother knows more than me). Then we came onto how the law of relativity dictates that if matter travels faster than light it ceases to exist.

This then brought a theory.

Imagine if you had a giant, perfectly solid wheel in the vacuum of space with a marking half way up the spokes. You then gradually spin the wheel until it eventually spins at a tremendous speed. Eventually the half way marker is travelling at 299,792,457 metres per second (1 metre per second less than the speed of light).

Surely the outside of the wheel will then be travelling faster than the speed of light, which would result in the outer wheel seeming to disappear.

But then what if you slowed the wheel? Surely it would reappear gradually from the half marker outwards right?

Bear with me here but here is what I think happens:

Once part of the wheel passes the speed of light, it ceases to exist on this plane of space and time. Instead, the matter is somehow transferred into some sort of information that exists on the alternate linked plane where Space and time do NOT exist. This information would in some way contain every detail of the transfer.

Now, lets say the wheel is kept spinning with perfectly consistent parameters for a year. Then, you slow the wheel down.

What I think happens here is the exact reverse of what happened when the wheel was sped up originally: The unsurmountable amount of energy is then naturally, perfectly reversed and somehow something natural then beckons this information from the linked plane where Space & Time does not exist and therefore the matter begins to form again until the whole transfer is reversed.

Also, seeing that the information of the outer half of the wheel has been held in a plane where Space & Time does not exist for a whole year.The outer half of the wheel would not have aged a second between both transfers.

Now, I know the above is in very mundane terms but is there any truth (I mean similar theories) in any of this. I hope there is. It seems to make so much sense to me. Sorry if it doesnt make any sense to you!!

It is not the case that relativity predicts that if matter travels faster than the speed of light in a vacuum that it ceases to exist. What is says is that matter cannot travel that fast. One reason is that it would require an infinite amount of energy.

The problem with your scenario is that you cannot spin a wheel fast enough for the outer rim to be going faster than light. So, given that such a situation is impossible the remainder of the scenario is moot.

But to go a bit further, there is no permissible scenario under which " space and time do not exist" in any sensible way. One might apply that notion to the singularity associated with the Big Bang and with a black hole, but it would not be a reasonable thing to do. What those singularities seem to represent is a breakdown in the predictive capability of general relativity rather than a physical thing. In fact there is a perfectly good, though complicated, alternative to general relativity (Einstein-Cartan theory) in which those singularities do not occur. So, basically you can forget about any scenario in which "space and time do not exist".

If you would like a very readable book written for a general audience that talks about general relativity and black holes, try Kip Thorne's Black Holes and Time Warps; Einstein's Outrageous Legacy. Thorne is a serious physicist, the Richard Feynman Professor of Physics at Cal Tech. He knows the subject and the book is a fun read.

4. nah that wont happen. as the edge of the wheel starts to approach light speed, its mass increases, so more and more energy is needed to increase its velocity. Sinse the edge cannot travel faster than light, neither can any other part.

5. Well, there's no wheel made of solid enough materials. (They would have to be infinity solid)
