Actually, once light has passed the horizon, it cannot escape the singularity's gravitational pull, therefore we cannot see beyond the horizon.
 
yes, but prior to hitting the horizon it is taking an incredible amount of time for light to return. once it hits the horizon it should disappear. thing is, I've heard arguments both ways that light will NOT slow down, it just goes normal until the event. have heard the other way, too. matter of fact, there was a lab where light was slowed down and stopped (read it a few weeks back on fark.com I think) Was a legit site like space.com or something it linked to. However, I have also seen lab tests where light was increased in speed in a lab (it apeared outside of a ionized noble gas chamber treated with some other crap) before it even entered the test environment, it appeared on the other side. It hasn't been published because they can't explain how it happened. I will try to google for these two later and post links.
 
Awesome man... I am really looking forward to seeing these links.

Would you mind also providing a link to where they stopped light?

I am really interested in this!

Thx again killians45!

some black hole theories (alot are not the energy, but it goes to show that SOMETHING is moving faster and slowing the wave lengths)

increase speed of light with gas chamber

couple other light speed breakers (supposedly, but trustful websites)

The experiments involving the "halt" of light made the biggest headlines around the year 2001. We still burn pizzas over that up at the observatory when I'm up there.

There's a lot to consider when talking about black-holes, too.

The idea that nothing escapes a black-hole is mostly true. However, in recent years, scientists have been studying various unexplained particle emmitions from black-holes. Also, let us not forget the incredible radio-band outputs from black-holes, which are also quite interesting.

Then of course there's the one line of theory going that black-holes may be like gigantic stomachs, ready and able to "vomit" up what they have captured...which would be interesting.

There's also a line of theory that black-holes destroy what they capture has some equally interesting applications.

As for the whole headlamps argument...it really boils down to what discipline of physics you wish to study the problem in, and the understanding that light has two forms which act differently at speeds.
 
From the speed of electricty through copper wire to what happens if joe blow got sucked into a black hole. Gotta love it :)
 
If you need horse manore, put some Linux and Microsoft people in a room together.

If you need theoretical physics, talk about electron speeds.

Nubius, haven't you learned yet that no topic in TF stays on topic for long?
 
Light can have mass, because it has been discovered that it has momentum. To have momentum you need to have mass.
