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.
FYI: www.serpo.org
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.
Maybe this sort of thing explains the mass insanity/delusion/stupidity engulfing our dear nation these days? These weird particles have ripped apart the time-space continuum and thus NASA is doing muslim outreach, TSA agents are groping grannies and infants and we’re discussing minting trillion dollar coins?
Just a thought.
Well played... ;-)
Not entirely without merit. Considering the size scale at which the neurons in our brains function, sufficient fluctuation in space-time due to virtual particle pair annihilation could cause interruption in the system or replication errors could be introduced.
Just a thought...
Well said, and perfect observation for this thread. It’s a little known fact that the great theoretical physicist Albert Einstein is responsible for putting the bubbles in beer:

Isn't amazing what you can get a computer model to come up with. Now how about putting the keyboard down and going outside and make some real observations.
Dark Energy and Dark Matter, the Philogiston and aether of the 21st century

Fascinating!
But
Who put the bomp
In the bomp bah bomp bah bomp
Who put the ram
In the rama lama ding dong
Who put the bop
In the bop shoo bop shoo bop
Who put the dip
In the dip da dip da dip
?
Here we go again with the “in and out of existence spontaneously” mantra.
Anybody who can’t see that is impossible, shouldn’t be a scientist.
First principle of rational thinking, is that something either exists OR doesn’t exist.
Aristotle: The law of non-contradiction. If someone denies that, it is impossible to have a rational conversation with him.
Along those same lines, I have wondered, due to observations by astronomer Halton Arp, if different rules that apply to certain sections of space/time.
He has proved, beyond a doubt to me anyway, that two objects, billions of light years apart, do interact with each other.
Could be that the redshift data is right and they are far apart to us, but in their location of space/time (reference frame) distance is a little screwy (a lot shorter) between them.
More scientist seem to be interested in discrediting him than finding a reason for the interaction observed in his photographs of close galaxy and distant quasar gravitational interactions.
No.
I want *dat* cordia.
Dat cordia over dere.
Well...I am just SO glad you could finally make it!
:D
[we still got happy feets?]
Yup!
<;^)
Braise Pob...
Hail Eris!
Just occurred to me that the media play the part of Eris perfectly - sowing discord among the enemies of socialism.
LOL!
I remember “Bob” from late night TV when music videos first came out.
[I think maybe it was on USA’s Night Flight]
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.
“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.

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...
