On page 134 of Mr. Hawking describes his concept on virtual Particles in his book (The Illustrated, A Brief History Of Time). Could there be a connection in the manner the Higgs boson interacts with the graviton and the anti-graviton, that could explain the effect of Dark Matter? Just think about it.

These particles are virtual particles like the particles that carry the gravitational force of the sun : unlike real particles, they cannot be observed directly with a particle detector, however, their indirect effects, such as small changes in the energy of electron orbits in atoms, can be measured and agree with the theoretical predictions to a remarkable degree of accuracy." end of quote.<br />My question is if Mr. Hawking can understand the existance of the black hole interacting with the particle pair(graviton and anti-graviton)&nbsp;that carries the gravitational interaction, could it be possible, because of the concentration of gravity at the black hole, and the fact that gravity can escape the black hole, where the photon can't, plus the production of these newly formed anti-gravitational particles have an effect on the way gravity is distributed in a macro system with a black hole core?

I was just wondering if there could be something to it, after I saw where some astronomers said the total mass of&nbsp;a galaxy&nbsp;is directly proportional to the&nbsp;mass of the black hole at its core, and did not include the Dark matter in the eqaution,&nbsp;they sort of thought as I did, this is strange. Also why doesn't the dark matter of our solar system have an effect on our outter planets, and the other exoplanets of other stars. Like I said I was just wondering. Thanks again.

<p>Dr Rocket,</p><p>I too am not sure of the status of investigations of the distribution. After all, until particles that create the mass are found, dark matter is just a placeholder for the observed gravitational effects. I wasn't aware that there was rarefaction or concentration toward the cores of galaxies, but if I understand the effect correctly, it would be much harder to determine that with so much normal matter present.</p><p>This certainly is one question I hope gets answered before I become part of the inanimate dust of the galaxy </p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
