Why don't everyday objects attract one another then? Even in a vacuum?
and they do... ever hear of a dust bunny.

That's great, but I'd rather see scientific evidence to substantiate your breakthrough. If you have any, please share.
No it is not. The mantle is very hot solid rock. It is able to deform plastically over long periods, but it is not a liquid. Think silly putty- pull it slowly and it stretches and deforms, but pull it quickly and it snaps.[/QUOTE
found my own answer forget it
They do, just not much. The 'G' in $$F = \frac{GMm}{r^{2}}$$ is approximately $$6 \times 10^{-11}$$. That means that the force between two 1kg rocks a metre apart is $$6 \times 10^{-11}$$ Newtons. Not very much. However, the force between an object of mass 1kg and another object of mass $$6 \times 10^{24}$$ kilograms at a distance of about 6,400,000 metres is about 9.8Newtons. How do I know? Because gravitational acceleration due to the Earth's gravity is 9.8m/s^2, I just gave you the mass and radius of the Earth and I know about Newton's shell theorem.Why don't everyday objects attract one another then?

One of the most obvious reasons of why Newton's universal law of gravitation must be wrong is the simple fact that everyday objects simply don't stick to one another in a gravitational manner, even in a vacuum. I've seen televised zero-gravity experiments aboard the shuttle, where rocks were fired at one another to see whether they would coalesce, simulating the accretion of micro-asteroids to form larger ones. ABSOLUTELY ZERO SUCCESS. Surprise, surprise. Still the penny doesn't drop.
Also, as Newton's law makes accurate enough predictions, clearly it is correct.
No, I didn't see it. Though I know plenty of people who work or have worked at CERN. My PhD supervisor and her husband met there, they are both theoretical physicists. A guy I share an office with spent 6 weeks there this summer. I was trying to get a place there for 3 months from this October, as part of my PhD, but it didn't pan out.I assume you all saw Prof Brain Cox on BBC4 last night, talking about the start-up of the LHC on the 10th September. The Higgs Boson has a ZERO% chance of being found. I bet you're all into a Higgs Field scenario, aren't you? Just wait and see o' yee of little faith.
So you criticise a theory you know nothing about?No I can't. But I bet that doesn't mean that my theory has no merit.
Angular momentum can be transfered by any force, but in the case of gravitational interactions, yes it would be the graviton. The graviton has no rest mass but it still carries momentum. Just as the photon and gluons do. They too have no rest mass but have momentum.And what of the mechanism which transfers your angular momentum? If it is a particle, it would need to have a high mass, would it not?
Does a graviton have mass?
Why should that concern me? I learn science from books, papers and lectures, not TV shows. I'm intelligent enough to understand the actual science, not have to be wowed by fancy graphics.Doesn't it concern you that it is clearly not enough to join two colliding asteroids together, which is routinely portrayed on TV, such as in 'The Power Of The Planet'.

You are way off. Try reading up on the NASA search for the Pioneer 10 & 11 probe gravity anomalies.

Er, just try dropping an object, and see if it accelerates as Newton's laws predict. Use those laws to predict the orbits of planets. It works. It is correct. A few anomalies don't invalidate the theories, it just means some other factor is in play.
btw, don't use old credentials to try and prove your point;
If you have a BSc in astronomy, you'd know your 'explaination' is completely crap, because it's not able to predict anything quantitative. Go on, post the scientific background. And being a computer modeller doesn't make you right. My father is a professor in computational fluid dynamics and have done contract work with Lockheed, Boeing, Airbus, the eurofighter and the supersonic car and he doesn't know the first thing about this kind of physics.
J All the maths is then pretty much the same.
It's the common sense aspect of simply seeing that the Sun's gravity is seen to affect the tides, but nothing else. Why can't you sense the Sun's gravity as it rises in the morning?
Whatever makes you think that? The Sun's gravity affects the Earth itself (google "Earth tides") and you, for example.It's the common sense aspect of simply seeing that the Sun's gravity is seen to affect the tides, but nothing else.
Snide answer: For the same reason that you can't sense the Earth's gravity. Think of it this way: Astronauts onboard the space station experience about 90% of the gravitational force they experience while on the surface of the Earth, yet they feel weightless while onboard the station. Nothing, including you, can directly sense gravitational force.Why can't you sense the Sun's gravity as it rises in the morning?
Riiight, like you were being truthful about having a BSc in Astronomy and don't even know the basics of orbital mechanics.The rest was just being honest.
150 lb person is about 0.1 grains (force) greater at noon than at midnight -- which is such a tiny amount that you cannot feel it.
