Dwarf planet Eris may reveal quantum gravity

Many galaxies appear to have stronger gravity - and thus more mass - than can be explained by their visible matter alone. Overly massive galaxies are most often attributed to dark matter, an invisible substance that interacts with matter through gravity. To date, though, no one has directly detected dark matter particles.

But a well-established notion in physics could hold another explanation for their size. This says that empty space is really a frothy, turbulent sea full of virtual particles - matter and antimatter that spring in and out of existence so fast that we can't see them.

Though they are tiny, quantum objects, Dragan Hajdukovic, a physicist at CERN near Geneva, Switzerland, thinks these bubbling particles may have opposing gravitational charges, similar to electrical charges. In the presence of a gravitational field, the particles would generate a secondary field, which, in the case of galaxies, could explain the mass discrepancy.

Hajdukovic's theory could also explain dark energy, the baffling force thought to be driving the universe apart at an accelerated pace. If virtual particles have gravitational charges, then space-time itself is imbued with a small charge that could be causing objects in the universe to speed away from each other.

Since time is linear [though some would dispute that] the end times have always been upon us.

Linear?

I have trouble seeing “linear” from inside this Chrono Synclastic Infundibulum.

Un-oh, definitely of interest. Thanks BenLurkin!

“Many galaxies appear to have stronger gravity - and thus more mass - than can be explained by their visible matter alone.”

I recall reading a sci-fi book that where many of the dwarf suns are actually bigger suns being seen through dyson spheres.

Well, after doing some light math in my head, I disagree and I'll show my work:

Now I'm having flashbacks from calculus and there's no way I could work those problems out on a supercomputer, let alone in my head.

It's pretty amazing that Hawking can do things like that in his head. I may not agree with the guy but there's no doubt he's one smart dude.

I stole the equations from Wiki's page on Hawking radiation.

No doubt zerO will solve this problem of virtual particles. If they're appearing and then disappearing because the anti and regular matter combine; shouldn't we get some energy out of that along the lines of E=MC²???

It’s like learning a language. Once you know the symbols and the syntax, everything else is writing the story.

Due to the fact that they are virtual particles of nearly no mass, they would emit the occasional photon. The crux comes when virtual particle pairs don’t collide or actually form real particles.

Then they form protons and electrons. Then hydrogen. Then gas clouds. Then stars. And the whole shebang starts over again.

Ad infinitum...
