Anyway, what I would like to know is,,, If the Sun did indeed disappear, would I still be able to purchase cigarettes and alcohol at the local offie ? (or would they float away off the shelfs )

Talking about instantaneous effects violating the laws of physics.
Cox was talking about electrons everywhere not being allowed to be in the same state, he said that if he heated up some material in his hand and caused the electrons to gain energy and switch states, then any other electrons anywhere else must instantly shuffle off to a different state.
We were talking about it a few pages back.
Ah, gotcha - mind boggling isn't it
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.
Good answer, it is mind boggling indeed. The more we learn about the world the stranger it is.

No folks I've got it right. The sun's mass distorts space and creates gravity. Take that gravity away and what happens? According to you lot - nothing happens. So what role has the sun played in holding the planets in place all these billions of years? None according to you.
The question is what would happen if the sun disappeared - so what would happen?

A load of sun bed shops would open all run by illegal immigrants cashing in !
The question has already been answered. Your conclusions are wrong. You are wrong (on many levels I expect) and by outlasting the non-buffoons on this thread by wearing them out through sheer exasperation does not make you any less wrong.
Tonka, I follow your argument most of the way but I'm struggling with the following: Your explanation makes it sound like the gravitons beaming towards the Earth in space can have a holding effect on their own with no body to pull against. In other words right up to the point that the last graviton arrives at the Earth the Earth would be held by those gravitons. But how can this be? Do the two bodies held together by gravity not rely on each other for stability. More akin to a rope holding two bodies together. Cut the rope holding the Sun and earth together and the effect would be instant. One part of the rope would fly off with one of the bodies and the other with the other. The rope could not hold either in place on it's own.
It wouldn't be instant with a 93000000 mile long rope.
There is a fundamental law, not yet disproven, that information cannot be transferred at greater than the speed of light. What evidence do you have that makes you think gravity acts otherwise? Because a bufoon with an internet logon says it's instant??

How do you know I'm a 'he'?
Listen, Moon-Unit, you are wrong.

Wow, has Joe completeley misunderstood the question which everyone else seems to understand?
I have posted a link which shows where the speed of gravity has been measured.
If the Sun were to go, how soon, gravitationally speaking, would we know about it? As the effect of gravity takes times to reach us, as discussed, travelling at the speed of light, the change in gravity will take effect approx 8 1/2 minutes after the sun has disappeared. What do you not get Joe?
No one has stated that the Earth will keep on orbiting an empty space forever, changes in gravity take time to take effect over any distance, the further away you are, the longer it takes to reach you. The Earth will fly off in a straight line 8 1/2 minutes after the Sun has disappeared.
Correct Joe, the warping goes, but like the rubber sheet metaphor the sheet does not flatten in an instant across the whole of the sheet. It takes time, the bigger the sheet, say the distance from the sun to the Earth, the time is about 8 1/2 minues.

Look uri - no-one has any idea how gravity works. They said as much on Horizon the other day. How do you know how gravity (minus its mass) would work? There can be NO GRAVITY without mass. The two are inseparable. No mass = no gravity. Geddit? You can't have gravity once the mass has disappeared. You won't find that on google because mass cannot disappear - so the question is moot.
