Can you catch light in a pot?

[ErGingerbreadMandude]

So you guys are saying gravity affects space time, okay, but how can gravity affecting space time affect light causing it to bent ?  
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?)

It was discovered that light needs no medium, but recently that is on the table. (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.
