Mastaba; although the Earth would continue orbit until the gravity wave (made up of gravitrons, correct if wrong) passes by, your reply deals with motion after decrease of gravity. What if there was no gravity to begin with? An earth not in motion can be affected by the sun only if the sun & earth exist (mass).

This is the micro explanation (most common). There might be a sub-micro (dealing with smaller than planet, mass), but people also explain this in a macro explanation, such as the quote above dealing with inner/outer-universe examples.

Where are you? Inside the universe or outside?

Nice lots of answers =) Oh and I never thought about the "When the sun explodes" gravity goes away.. or does it? :P

You might educate yourself a little in current research about gravity, and about all constrains that are known. Gravity has NO aberration (proven by moon eclipse), thus the most simple explanation would be effect of central star disappearing would be immediately noticed. (even before light would disappear from the sky)

You are also talking about particles that highly likely doesn't exist. The hint could be distance at what gravity interacts.

Of course considering photons are momentum carriers, the gravitational lensing effects would work. On the other hand not all people believe that photons are massless.

Two links the second talks about effects that could be viewed as a spin affecting momentum carriers. The first talked about an old irrelevant experiment.

I consider more important that research about passive mass, and other types of masses.
