Have a look at First Light Optics website. No crap on there and they'll give you good advice. I'd stay away fom the Jessops ones.

Don't make assumptions or answer on my behalf Joe. I do have a life outside of the Internet you know. :P

It's an interesting idea but if we assume that the force is carried by a gauge boson (it's a reasonable assumption given that the other fundamental forces are carried by gauge bosons) then there will be inevitably be quanta involved. This suggests that you won't see a gradual attenuation but...

Yes do think about the rain analogy. Only the stuff that hits us wets us - very true but after the condensation stops in the cloud there are still drops falling - those drops will eventually wet us too until the final drops reach us and the rain finally ceases. Good analogy :mrgreen:

Yep but that's past the event horizon and we can never know what's beyond that. Unless a naked singularity shows up and that would be really weird.

Yep, any theory is good until it's proved wrong. Such is the basis of science. :mrgreen:

Mass can't be magically removed or destroyed unless it's converted to energy. Likewise energy can't be destroyed only converted to other forms of energy or condensed into mass. Conservation of mass/energy - fundamental physical law, innit.

More correctly, its the point at which escape velocity for the local system exceeds the maximum velocity permitted in the universe, i.e. the speed of light in a vacuum.

That's an interesting viewpoint. Nicely reasoned and well argued but I suspect that you're wrong. You're right about gravity, of course. We know very little about it as a force other than it's attractive and obeys the inverse square law at a local scale. It's astonishingly weak as a...

Again, show me where I said that it could. :mrgreen: You do like to attribute things that people haven't said to them, don't you?

Oh it's an imaginary universe with magic? In that case, the unicorns will keep the planets in their orbital paths. :lol: In order to perform a thought experiment, you need a mind capable of rational thought... ;)

Again Joe, you utterly failed to either read or comprehend my post. Try actually reading it with an open mind and maybe, just maybe, the light of comprehension will dawn. You've hoist yourself with your own petard regarding thought experiments but you haven't realised it yet. :mrgreen...

You clearly don't understand your own question which is a pretty poor position to start a debate from. If you don't understand that the speed of light is a given maximum for physical effects in the universe then you don't understand physics. I can recommend a decent science foundation course...

Not in a straight line - remember there are other masses and hence gravitational sources in the Solar system ;)

Nobody has said nothing happens - keeping on saying it ad nauseum isn't going to change that. What's been said is that there's no immediate effect on the Earth. Mass distorts the fabric of space-time - the analogy of a dent in a rubber sheet will do for this. Remove the mass of the Sun and...

Think of the rope being shaken to produce a wave that travels along it, now make that rope very very long stop shaking the end suddenly. It'll take a while for the pre-existing waves already on the rope to cease and the rope to become still. That's a reasonable analogy :)

Ah, gotcha - mind boggling isn't it :D That's a quantum effect - instantaneous effects are permitted at the quantum level - entanglement is a good example. Once you scale up to the gross physical level then all bets are off. :)

Erm, the relevance of the Pauli exclusion principle to this question is what exactly?

Good grief. I know it's a thought experiment which is why I used my brain to answer. :roll: However, even as a thought experiment you don't ignore the laws of physics. Nowhere in my responses have I said the Sun's influence is insignificant. Nor have I said nothing will happen. Try...

You're either still missing the point or you're being deliberately obtuse. Any effect would not be instantaneous - that would violate several laws of physics.
