The change is rather large isn't it.

"My colleagues and I have successfully experimentally demonstrated that the force of gravitation between two test bodies varies with their orientation in space, relative to a system of distant stars,"

The astrology nuts will have a field day with this one.

I was trying to explain what I know of relativity to a buddy recently. In particular, I was explaining length contraction and how this is not a perceived effect but a real one. And I got to thinking about the contraction of a rotating spherical body as it nears relativistic speeds. Contraction along the axis of travel is one thing, but when the contracted body is rotating so that its contracted part is changing seems really bizarre, although it makes perfect sense mathematically ...

Perhaps.

Of course this must eventually lead up to the G-String Theory which covers, well, not much.

Well, a famous "remote viewer" (an actual participant in the Army's real Stargate program) has done a pretty comprehensive book about the topic of remote viewing -- "Remote Viewing Secrets, A Handbook," by Joseph McMoneagle -- and I believe he devotes an entire section to studies which have shown a strange correlation between successful remote viewing trials and local sidereal time. Local sidereal time is based on the earth's orientiation in space (that is, earth's orientation to the backdrop of stars). This can be interpreted to be an indicator that all directions are not the same...

Gravity changes and is controllable...

The ether is real...

These two things will forever change our understanding of, and control of, existence...

Not tin-foil hat time. This was published in a respectable journal. Now other scientists will try to duplicate the experiment and its results.

I find this very interesting not only because it could shake up the field of physics, but because it shows even more clearly how little we really understand about gravity. Heck, I think the article implies that General Relativity used G, which Einstien assumed was unaffected by orientation. It's so neat to think about how much could be shaken up by if this is proven out.

Goody! Let me know when they come out with that anti-gravity belt so's I can slip it on when I go to the Dr. I am getting so sick-and-tired of his constant carping about my weight.

Michelson-Morley and Maxwell notwithstanding, I presume. Be sure to post a link to your paper - I'll be able to tell my grandchildren that I traded thoughts with a Nobel Prize winner before he got all famous ;)

About 50-50. They publish a lot of mathematical "what-ifs", proposed alternative cosmologies.

Why did this obscure piece find its way to a popular science news article? Because Gershteyn called a UPI reporter. Note that this is not an MIT release.

Well, it *is* interesting. Gravity is a sort of pet peeve of mine: it keeps us from getting into space in any meaningful way. Anything that might help open a door to overcoming or manipulating it to get us off the planet is very welcome to me.

At any rate, I imagine that a bevy of scientific experiments to test this is in the offing. It'll sink or swim the same way cold fusion did and in accordance with the methods of the scientific community.

I just hope some practical applications can someday be derived from this at some point...maybe through change in other physical theories dependant on G.

There's some very interesting reading right here...

Here's a paragraph, for example...

Existence cannot not exist. Moreover, no vacuum void of existence is possible. "Vacuums" of the matter field can exist as in outer space, in vacuumed-pumped containers, and in areas between electrons. But, all those volumes are filled with the unmovable, frictionless ether or existence field -- a uniform, continuous field of existence.[ 23 ]

Does this mean I can lose 0.054 percent of my total body weight just by standing in a different position?

Yep, and if you change positions frequently, you can lose 10lbs by summer ;-)

I see no reason not to accept this result, pending confirmation by other groups. If I were a betting man, I'd say that this is likely to be overturned--extraordinary claims most commonly are--but in the meantime I'll assume it's correct.

It has been known for a few years that there is an anomalous anisotropy in the polarization of the cosmic microwave radiation background. My first test for this new result would be to see whether the two anisotropies line up. If they don't, I would strongly suspect that one of them is wrong.

Could this account, at least in part, for the uneven distribution of matter in the early Universe?

No, because there is no global anisotropy to the distribution of matter. On the largest scale, it is fairly even.

The unevenness of the matter distribution in the early universe is well described by acoustics.

I really don't have enough expertise to comment, but there is some precedent for variable measurements. Also, some precedent for ideas on the edge.

Just for fun, the Attractive Universe Theory
