Here's something, If light is the fastest speed then what about darkness. You think it comes as the sun goes down just as fast.

Nice joke.

I'm so fast, I can turn the light off to my bedroom and be tucked in my bed before it gets dark.

I've always hated that definition of 'light'.

That makes radio 'light' too.

In fact, in a sense, by that definition of 'light' you could say everything is made of 'light'.

Light cannot be the fastest speed in the universe. Its stupid to think so.

If black holes can suck light; meaning that the speed of light is not fast enough to escape... There must be something that can be faster.

Don't forget Wormholes, Schwarzchild blackholes (Black hole connected to white hole). And all this string travel thing.

Also don't forget space lag, the faster you go = the more you go back in time (or is it)

Also, man will never know everything because there will always be new things discovered.

And I'm also sure there is something faster than gravity.

Then why can a black hole suck light if they travel at the same speed?

Surely gravity doesn't move.

You can think of gravity as a ripple in spacetime. This ripple is said to travel at the speed of light.

It's not that light is being "sucked in" to the black hole. The point is that anything trying to escape a black hole would have to travel faster than the speed of light.

I don't really know enough about general relativity or quantum effects of gravity to explain it properly. Well, I could read up on it and explain it to you - but I don't want to and it would take a quite a while.

Excellent doco which I've managed now to find on youtube.



It explains it perfectly visually too.

edit: go to about 3:50 and watch onwards if you just want to see the juicy bits.

I didn't mean gravity is faster, I meant light isn't the sole fastest speed, as gravity moves at the same speed. You might as well have titled this thread the speed of gravity.

Black holes do not "suck" in anything. So far as we understand it, mass creates a curvature in space-time. If that mass is large enough, such as a planet, or a star, or a black hole, then the curvature is extremely great. Light does not change direction at all, it travels in a straight line on a curved surface. The only difference with black holes is that the curvature is extreme enough that light is not just "deflected" as we would say thinking in our poor three dimensional vector model as it is with a planet or a star, the gravity well is so steep that all light that passes within the event horizon falls in it.

We think that gravity most likely propagates in waves similar to light, but as Scorpion mentions we haven't found the particle that carries it (the gravitron). We believe that it may travel at the same speed as light, we do not know. I am pretty sure gravity is the force that we know least about out of the gravitational, electromagnetic, weak and strong nuclear forces.

Black holes must be a big rupture that leads nowhere if I picture them with einstein s'theory


like


--------------o-----_O_--------- Normal space fabric with planets

------  ------- = Black hole?


if universes where like this...

-------_O_-----------------     ---------

----------     -------------_O_----------

------_O_--------------------     -------

It could mean black holes are getaways to other universes and white holes are what comes out of a black hole on the upper level.

Could this also mean that there is one central point of massive gravity at the very bottom of this "building floor" like multiverse?

It would be pointless.

(well the point would be a singularity, but that was the joke. Explaining it doesn't make it a good joke, but I'm tired so there you go.)

You're right...I had assumed light always travelled in straight lines

And yes, I know a bit more about sound...doesn't change the fact light ain't a 'force' though

Mitch I think that you would agree with me when I say:

If a tree falls in a forest and there is no one (NOTHING) around to hear it, does it make a sound?
