I think so. There must be some way of explaining it better than "it just does". (What other scientific questions have the answer "it just does"?)

In the classic experiment, particles sent through a single slit behave as if they've been sent through a single slit, while even if sent one at a time in a direction with two slits, they display an interference pattern after enough have been sent to make a pattern show up. That still dosn't explain really how each individual particle KNOWS it has a choice of two slits... right? How is this mathmatical change distributed through the path of the experiment? It must happen instantly, therefore the effect travels faster than light - but no force can travel faster than light - as it needs carriers of that force to interact with. What if the very act of creating an extra choice in the path of/for the particle makes some kind of inherent "pattern" within the fabric space/time for the particle to travel through? This "pattern" is what directs the particle to exhibit it's wave-like properties or interference. No force involved, just math. (While writing this I just struck upon the idea that gravity could also be faster than light? If the sun suddenly wasn't there - would we still orbit where it was for the next 8 mins or not?)

Perhaps it's like mass having a 'pressure' that pulls against space/time... matter interacting directly with the dimensions that the mass is in. Does that help any?

Because electricity and magnetism are almos tthe same thing? Hence, "Electromagnetics"?

I dunno. The Planck duration?

Time does have a speed - the speed in which it passes for the universe! Space is about length, not just distance - and time is about speed, not just duration.

*ahem* It was suposed to be a prompt for the next poster to say something like: "Yeah? Go on then..." It all has to do with the fact that matter already travels through time at the speed of light so to move in space you have to take some of that constant away from moving through time. As a result, you can't move faster than you're already travelling, ie: travelling faster through space than you can travel through time.

Time exists for the same reason that space has a volume.

I thought that was a really bad episode. "Oh we don't know enough about Klingon physiology to have realised Worf has two hearts" because our medical tricorders and transporter system records are so obviously pathetic they can't detect anything like that.

I finally figured out why faster-than-light speed travel isn't possible. Go me.

Was it something I said about a moving pendulum having more mass?

Density is just an aspect of mass, although I don't think pressure would have any effect - after all, pressure against what?

I'm sure I read about an experiment that produced an energy reading of less than zero, something to do with particle/antiparticle pairings where one of the two was removed, leaving an absence of energy where there wasn't before... Or perhaps it was negative mass. Or something. It was a while ago and I don't remember the exact details very clearly.

I figure Gravity was just an effect of 4D space in 3 dimensions, and not actually 'transmitted' by anything. Or am I taking the 'ball on a trampoline' 2D-3D analogy too far?

Different types of mass? But aren't all masses made up of energy anyway? I'm pretty sure energy does weigh something - after all, a moving pendulum weighs more than one at rest.

But gravity isn't really a wave though, is it...?

Time travel can't really be possible, because that would mean that at one point in time in the universe, there is more total mass/energy than at another point in time in the universe.

How much does a photon weigh? According to E=mc² if a photon is made of energy, it would have a (albeit an exceptionally small) mass, therefore it should exert a gravitational influence on it's surroundings, shouldn't it? Which brings me to another question: do high-energy photons move slower then low-energy photons? If they really are heavier, then should they be not quite able to reach the maximum speed limit, as there's more photon to move around...?

Is the existence of the graviton particle really neccessary? If gravity is merely a side-effect of mass in the space/time universe, why is it regarded as a 'force' such as electromagnetic, weak and strong? I don't believe it requires a specific entity to transmit this force, as gravitational influence is just an inherent property of the universe, caused by the pressure of matter in space/time. Oh wait... darn it. *ahem* If pressure causes friction, gravitons could be what are generated by that 'friction'. I was all convinced, then I had to go and re-confuse myself by writing it down using pressure as an analogy.

Heya Another newbie here from the UK! My areas of interest are mainly metaphysics and philosophy, with some quantumn mechanics and string theory thrown in for good measure.

Why don't you just have 2 different people measure it at the same time, then they can measure one thing each?

Would time also be produced from these White Holes, like in that episode of Red Dwarf?
