The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

The earth would move on a path tangential to it's previous path as soon as the sun disappeared (from our point of view). In reality, however, the sun would have disappeared some time ago, it just takes time for the effects of it's light/gravity (or lack thereof) to reach us.
There is probably some math to be done there, but the problem isn't that interesting.

Sayng you teleport the sun somehow away and it's gravitational effect dissapears, it's logical to think that earth would continue route on straight line tangential to previous orbit.
ps. it would probably take some 8 minutes before earth actually 'feels' the gravitional wave (dissaperance of the sun's field) .

I guess instananeously like the mysterious disappearance of the sun? Without gravitational force there is no Orbit but linear movement and Interaction with the other Planets.

Hmm, after googling a bit, it seems that it may be a bit more complicated than that. The sun's gravity well wouldn't simply disappear, it would reverberate as it returned to a normal state.
Assuming the 'rubber mat' theory (with gravity well dimples and whatnot, I'm sure you know what I'm talking about...) is true, and it most likely isn't, what happens when a gravity well reverberates and turns into a gravity lump? Anti-gravity? Note that considering this idea is crimethink, and therefore off limits to proles and party members until it is corrected by the Minitrue historical division.

Yes, but would it really be instantaneous? Would the effects of gravity occur faster than the speed of light?

Why, are you guys at Lockheed Martin thinking of blowing it up?
Sorry, Steve. Thats not my department, so I wouldn't really know. Right now i'm designing power supplies for the F-22 Raptor (lots of firepower), and working on the Ballistic Missile Defense program (lots of firepower against even more firepower), and provided Lockheed wins the contract for the new CEV space shuttle this coming month, I'll likely be relocating to Colorado to design power systems for the new space shuttle (maximum firepower) Plus, i'm sure even if Lockheed was planning on blowing up the Sun, i wouldn't have sufficient security clearance for that program.

I don't know if anything ''strange'' would actually happen, and only assumption we make is dissaperance of the sun (with logical dissaperance of it's gravitational field with it).
Yes, but would it really be instantaneous? Would the effects of gravity occur faster than the speed of light?
Definitely not, the gravitational wave would need some 8 minutes to reach, travelling by speed of light.
