That's true. I was originally confused about the axes and view of his original picture. My picture does not answer his question though.

except that your picture is in 3-D. We have been talking about 2-D. If you reduce your picture to 2-D, you have more or less the exact same picture we are using.

You are welcome. That bend can be calculated using the mass of the object and the distance the light is from the object.

yes, in that 2-D universe, that's what it would look like.

I am currently studying physics as an undergraduate as well. does your school have some sort of physics club, or outreach activity (maybe an open house)? Those are the events that really showed me why I love physics so much. If you are propelled by your love of learning, and your excitement...

If we look at this 2-D universe from our 3-D universe, when the light is near Earth (or another massive object) its path would look like it bends.

sorry, I didn't get to see you post about the marble, but I'm not quite sure what you mean by it. Could you re-phrase the question?

The question becomes tricky when you say a straight line. according to the light, it does move in a straight line, but when you move to a reference frame like the one you are talking about, the light's path would be non-linear for a time. The surface of the mattress represents space. light...

You are correct that space would be "bent", but there wouldn't be "gap". I've always heard it best described as the Earth being a bowling ball on a mattress (or some other squishy surface). It creates a depression in the mattress. The trick here is that light is a part of space. it has a...

yes, heat is a macroscopic definition of a change in energy (which can be produced by a particle moving to a less excited state). When you get to a small enough particle, we see heat as only a change in energy. Therefore, the neutrons would get excited, bounce around faster, and produce...
