quantumbiocommunication.com — A mysterious force is ripping through physics and astronomy departments these days. It has splintered long-cherished theories and has caused otherwise rational scientists to latch onto a weird and ugly notion.

doesnt string theory and quantum physics dissolve the whole gravity "theory" ?

Is there gas leaking from Uranus?

You heard it on Digg first: Gravity Leaking is the new Global Warning.

It's good to be down to earth, but a little levity is nice too.

See! I told you so! If the US government keeps using those Flux Capacitors to bend time, we are all doomed!Now if I can only figure out who keeps drinking my beer :)

I knew it!!! I knew it!!! Thought I was going crazy for a sec.

hankryan:"So just like any sort of PHYSICAL wave loses energy as it travels through a medium, it might make sense that GRAVITY waves lose some of their "energy" as they move through space."Things don't just lose energy. Energy must be conserved (overall). Also, to clarify, if you are talking about the creation of gravitional waves, the masses must be accelerating. It works in the same way as electricity and magnetism. In order to create a radio signal, you must accelerate electrons in the antenna.Just to clarify, there are many different theories out there that have many predictions, but the problem is that we haven't figured out ways to test them at this point in time. These theories are not just conjured up. They are highly constrained by the basic laws of physics. Anyone can create a theory, but we must be able to look in certain limits of the theory and get real physics. If not, you go back to the black board.I will clear up your ideas about the gravity leaking ideas. As far as we can see, we live in a four dimensional space-time (3 space, 1 time). A current theory of quantum gravity, namely string theory, says we live in ten dimensions. One aspect of string theory is the existence of branes. So, our universe would be a three dimensional brane (3 for the three spacial dimensions). The fourth dimension we see, time, lives everywhere. According to the physics, everything that makes us up (electrons, quarks ...) is constrained to live on this brane. However, when we get into the nitty gritty of the theory, we find that the graviiton (gravity) is not constrained to the brane. It is allowed to leak off the brane and travel in the extra six dimensions. This model, properly explains why the gravitational force is so much weaker than the others. This is the basic theory side. If you have any questions, let me know.Also, there is no heating that goes on as a graviton leaks. Once off the brane gravitons can only interact with other gravitions. Heat is made up of photons (light).As for an experiment, good luck. One way to verify this theory would be to be able to detect gravitons (LIGO). If we could do this, we would have another way to test the theory. Another way to try to verify this theory would be in collision experiments. If we could create gravitions in collisions, they could they leak off our brane and we would see a violation in the conservation of energy. Who knows, but if we saw it, it would be very big.
