I'm actually kindof impressed.

Black holes don't attract light, light has no mass. Gravitational lensing is because of general relativity, the large mass bends space, so the photon may appear to travel a bend path, it's actually the path that goes straight through space.

What is this?! I leave you guys for a couple days, just to read a little article and I come back to find a thread half filled with confusing theoretical physics, and the half filled with pseudoscience?

What the heck guys? Where did you leave room for the time machine??

Photons are affected by gravitiy, afaik... hence, photons cannot escape from a singularity...

That's actually only somewhat correct.
We perceive them as being affected by gravity. What actually happens is gravity bends space-time - the photon is always travelling in a straight line locally that is, we only perceive it to be a curved path

Well, after all the researchers have "cheated" a bit, explaining the mass of photons ..... they said that photons have no "rest" mass, means, zero mass in rest condition ..... but, afaik, for a photon is theorically impossible to exist, in rest state .....

("comma 22" ? ..... )

Ok (I'll buy that) - apologies to Bluefan as he essentially was saying the same thing, but I didn't understand him the first time around.

Interesting!

It's all really exciting stuff; before I graduated with a Computer Science degree, I elected Astrophysics as my major. Unfortunately I decided to let the $ sway my career path... Don't get me wrong, IT is an exciting field in itself, but the Universe is the ultimate playground for the mind...

I'm still playing catch-up with all the new discoveries, trying to cope with the concepts of Dark Matter and Dark Energy (anti-gravity, anyone...?) but it is really awesome stuff! And it's also amazing how Einstein's work is still the basis of all current-day assumptions, despite the vast increase in resources available to scientists today...

Don't worry, if one were highly inclined toward theoretical physics, you would probably be a student with low grades, who felt like the pace was too slow. J/K

Speaking of which,

What is the mass of a photon?

Someone smart please comment on the following statement: there is no such thing as an anti-photon. My reasoning is that anti-matter produces light that is indistinguishable from light produced by regular matter. Here is another way of saying this: if some very far away star made out of anti-matter, we'd never know as it'd look the same as any other star to us.
