Isn't light gravity? Or light is energy is gravity?

Light is energy is mass is gravity?

I too have pondered the 'speed of gravity', particularly with regards to black holes and their immense gravitational pulls that can suck in light. Does matter entering a black hole get any where near the speed of light as gravity sucks it in? And how does something become infinitely dense? (I mean aside from watching Coming of Age?)

You have tasty thoughts.

Could a black hole absorb light and everything else and change it into dark matter?

Could we recruit a professor from a physics website to become a BCG member? They could then answer all our questions. In return we could give the physics website someone who could answer all their questions about On The Buses?

If we could crack open Jake How's head, we'd unlock the answers to everything.

Any excuse would do.

When I was at school our science teacher told us that when we look at the stars, we're actually looking backwards in time because the light from the stars takes thousands of years to reach our eyes. He asked if we had any questions and I said "So that means I'm also looking at you as you were in the past, a tiny fraction of a second ago? Which means that nobody ever sees anything as it's actually happening right now." I thought I was being very clever but he just told me that of course I'm not looking into the past at things on Earth, only in space. I objected but the old c**t told me to shut up, and everyone laughed.

It always bothered me, that. I'm still sure I'm right.

And now over to one of you lofty-brained eggheaded physics faggots to prove me wrong.

No, you were right. For all intents and purposes it's not looking back in time (but then in a practical sense nor is looking at the stars, as you can't influence them). But I can see why your teacher might have found you a little Mister-f**king-know-it-all. (Who'd be a teacher?)

When I look at your clothes Lee, it's like looking into the distant past.

Zing!

(plus I can see the punchlines to your jokes coming from Venus - double zing!)

Kiss my Uranus. Zing!

Oh hold on, that doesn't work.

Lick my Aries arse?

Perhaps not.

I would kiss Uranus but it's covered in asteroids. Zing!

Kiss my wormhole?

Tongue my ring. (Of Saturn).

I'd kiss yours but I can't get near it for the Klingons! Zing!

This is desperately poor. I'm off to 'polish my telescope'.

Laterz.

Lick my greasy Pole Star.

You were right, but the speed of light = 983 571 056 feet per second

As a quick rule of thumb, that's about 1 foot per nanosecond, so if your teacher was 15 feet away from your eyes, you were seeing what he was doing 15 nanoseconds ago.

And then there's the time it takes for the light to be detected by the eye, converted to nerve impulses, transmitted to the brain and interpreted by the software in our heads.
