"Are we being decieved?"

Basic maths/physics teaches us that momentum is velocity * mass.

However, advanced physics tells us that mass changes according to velocity, up until light speed, where mass is infinite.

Surely then, momentum cannot be so simple as mass * velocity since velocity dictates a part of mass...

Am I the only one who thinks this? Or is there in existence a more complicated formula which calulates momentum?

Just a thought...

I hope he does, he slavers all over the place.

tekkin the mick outta stephen hawking isn't quite sporting is it?

Anyway, old stevie'd wipe the floor with you lot anyday .......... ;)

And why does he talk in an American accent?

If it *does* slow-down, does that mean Stephen Hawking can still "see for miles" (but can't eat soup or bend one out)

Better hope that light speed can be beaten then. If it slows down to say 5mph, life will become slightly unbearable...

An interesting hypothesis.
If you extrapolate the sum total of the mass vs equilibrium ideal, then once can surely realise that nobody cares and this is posturing beyond normal limits.

And I would offer up the old age theory of boobs = better than DVDs

Light speed is constantly slowing down. Bet you didn't know that ;), only theorised very recently by scientists who discovered things (dunno what) which could only be explained by light speed slowing down.

energy which for most purposes is mass?

an interesting viewpoint.

That's like considering electricity as a solid object which can be held without containment in the palm of your hand surely?

Then again, I'm no expert on relativity.

Personally, I think it's possible to exceed the speed of light, and see such speeds not as an ultimate limitation, but as a challenge to mankind.

...

But I know nothing...

Im more a Biologist and chemist.

I was reading up on relativity a few months ago, and it seems that mass doesn't actually vary with speed.

I don't have the addresses of the websites I used, but the general gist of it is that travelling extremely fast increases the energy of the object, and it's inertia, but not it's mass, which is absolute.

At the speed of light, mass becomes energy... so I assume that very close to the speed of light the extra 'mass', is in fact energy of some sort, which for *most* purposes has the effect of being mass.

I think there may be a more complicated equation for momentum... there generally is for most equations. The equations of motion we're familiar with are mostly Newtonian... good approximates for everyday use, but not normally the whole story.
