Scientists ponder the problem with gravity
Space COM ^ | October 18, 2004 | Robert Roy Britt

Imagine the weight of a nagging suspicion that what held your world together, a constant and consistent presence you had come to understand and rely on, wasn't what it seemed. That's how scientists feel when they ponder gravity these days.

The entire universe is exapnding. Gravity is simply the observed effect of the expansion as particles accelerate outward from each other. Hence, things seem to be drawn together, but in fact they are merely getting bigger.

To simplify: Put Michael Moore in a room with a suicide bomber. MM is getting fatter, and the suicide bomber sets off his vest. They seem to be drawn together at different rates, but they are actually simply expanding, each according to their specific physical natures.

Democrats don't repeal laws, They just make them endlessly more complex, find a way to tax it and redistribute the proceeds.

The Edwards approach, is that the wealthy have an unfair advantage under the law of gravity therefore they must automatically add 5 lbs for each 100,000$ of income. The poor who have been trampled unfairly by rich republicans get to deduct 5 lbs for each child under 27.

I almost forgot.

Women and children hardest hit, and something or other about the homeless, Suv's and a womans right to choose, and don't forget the environment.

Bush is to blame, yada,yada and one more yada.

Is it fair to have an analogy of gravity that is dependant on gravity to work?

Probably not, but then, I'm an evil republican (of sorts) who doesn't care about fairness!

Do you know anything about gravitons? For some reason the concept is bouncing around my head. Guess I need to look into it a bit tonight.

Science list Ping! This is an elite subset of the Evolution list.
See the list's description in my freeper homepage. Then FReepmail me to be added or dropped.

A simple problem to solve my little sausage makers:
You see, as you get closer to the speed of light (the Pioneer spacecraft are traveling closer to the speed of light than the earth is) not only does time slow down, but also velocity slows down. The logical outcome is that at the speed of light, not only does time stop but velocity becomes zero.
Ingenious, isn't it?

Voyager passed both Pioneers a couple years ago.

It must be he election messing with my mind...

GRAVITY: It's Not Just a Good Idea... It's the LAW

... and the only valid law in Russia.

Gravity challenge is something Lizzie Edwards could relate to.

Dang, I was going to post some such Mrs. Edwards witticism, but you were right on it!

We had a thread on this about a month ago: Pioneer [gravitational] anomaly put to the test.

I am wondering if the expansion of the universe has an effect on the trajectories. There are inflatons and Higgs particles out there, here, too, as well as dark energy, and all this is still abductive. Perhaps they will modify gravity from a strict inverse square by adding a lower power weak component. Perhaps they will find yet another phase state or find post-inflation large-scale quantum effects.

Perhaps. But somehow the planets themselves, which are certainly responsive to gravity, always seem to orbit the sun in very predictable paths. Whatever is affecting the probes is very odd indeed. Unless there are anomalies I'm not aware of.

These thing have the mass of about a mole of protons

A universe mass of about 10 kilograms just before the Big Bang accounts fully for the mass of the universe as we observe it today, even though we can see only about 10-50 of the universe as we look out to our horizon radius of 13.5 billion lightyears.

It's obviously caused by illegal aliens! (I blame Bush...)

Look at the effect caused by light passing by a black hole or neutron star (gravity lense). This is in line with that.
