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.

does anti-matter have anti-gravity?
>>does anti-matter have anti-gravity?<<
Does it Matter? ;)
No one knows for sure.
The gravity of the situation matters...
Couldn’t resist....
This could explain all the weirdness in the report on Serpo and it’s weird “gravitational properties”, but then again Serpo is probably bunk.

Oh, hell....Discordia.

This would play well into Hawking's "black hole radiation" theory.
I like it.
Makes a lot more sense than some Unobtanium substance we haven't ever seen and might not be able to find.
My God... It’s full of Fnord.
Let’s do the time warp again.
We are back to the days of spontaneous creation. .

Like American Idol contestants.
Can’t.
Doc says I need to cut back on virtual salt.
Massive things are out there, but visibllity depends on relative velocities.
Bravo!
;D
I guess, I’ll just relax this weekend in my own frothy, turbulent sea full of virtual particles and consider the matter.
I see nothing here that I didn’t suspect from the beginning, at last they are waking up to what I knew all along..........or something like that!
I’ll be here all week. Try the veal.
Every Ostrich a Czar...
I understand what you mean even though I have never willingly watched any show likeAI.
The few times I have seen these sorts of shows (against my will at a sister-in-laws home) I was irritated immensely by the so called judges arrogance and snide remarks. I have never seen two episodes in the same season.
Having classical music education I know that the judges have less talent than some of the contestants they denigrate. Modern technology can cover a multitude of sins in music these days.
