Wait, if photons have no mass how can they be affected by the gravity of a black hole? O.o

Can you catch light in a pot?
|
This is a question for CD, though slightly modified.
Hey, CD, how often do you light the pot? Playing Cluedo with my mum while I was at Uni: "You did WHAT? With WHO? WHERE???"

You make people miserable and there's nothing they can do about it, just like god.

Pooley,
Contrary to what is popularly said, according to Einstein, gravity affects Energy and is produced by Energy. Mass is just a special form of energy. As IATIA says above, think of it as curvature of space+time and it becomes clear that everything is affected!

Light doesn't need a medium to travel right? This is confusing. According to my knowledge, light has no mass, light doesn't need a medium to travel, I mean, if light doesn't need space time to exist or travel how can the effect gravity have on space time reflect on light? (is my question legitimate or should I read up on it?) RE: Can you catch light in a pot?

(The Michelson–Morley experiment may be flawed) Think of space-time as a river that anything will float in. Drop anything in and it will flow with the river. The speed of a boat includes the speed of the current. Light of course is a little more complex than that, but the principle is sound. Space-time has always existed. Without space-time, there would be nothing.

If I could put into words how intelligent you are, I think I'd die, I'm not sure why, but I think I'll die, you're THAT intelligent. It's amazing to see you come up with simplified posts that explain complex.I just want to shake your hands and thank you for sharing earth with us. You are awesome. I have some ideas and doubts regarding light(they're pretty wacko,on par with "are you smoking again pool?"), you'll be one of the top persons on my list to reach out to. Thank you thank you thank you. 
An easier way to visualise it is to think that light isn't being curved by the effects of gravity.
Light "thinks" it is going straight. The warped space it is travelling through is the only thing not straight. You have to be "outside" to see this effect. Just like here on earth we don't feel like we're whizzing around in space at thousands of miles per hour. Simple relativity.
