Virtual particles in space.

Okay, I agree for a uniform energy density. But what about for a uniform mass density?

[InfiniteNow]

Are not mass and energy one and the same?

sebby, I don't know what the density is over all space, I'm just saying that we do not know for sure what the energy density is in intergalactic space. One of the things that causes problems in any discussion like this is that we (humans) are infected with a virus which obviously includes me and the name of that virus is THE ILLUSION OF KNOWLEDGE.

I think there is a confusion.

 

I have never asked you to tell me that which modern science cannot answer: the energy density of a vacuum.

 

But I have suggested that we can now about it's distribution even if we do not know it's exact amount.

 

If energy density comes from virtual particles, then it MUST be uniform on the macroscopic scale. And if not, it will still probably be estimated as uniform on an intergallactic scale. Thus we should be able to determine the type and direction of the gravitational influence of it even if we can not work out it's exact value.

 

At the risk of emulating Buffy and Turtle,

 

A little knowledge can go a long way,

A large number of theorists have said there should have been as much matter as anti-matter created in the Big Bang but since we have a matter universe there must have been more matter than anti-matter. If your idea about the attraction of matter for matter and the repulsion of matter for anti-matter is correct, how would this fit with their guess?

[Little Bang]

Firecracker, that is a very good question. I assume you are referring the other thread entitled “MY TURN TO GUESS, BY JOE BLOW NOBODY. There are some things I need to explain before I give my opinion. I think the theorists were correct in saying there should have been just as much matter as anti-matter. The force of repulsion between matter and anti-matter, the force of attraction of matter for matter, and the force of attraction of anti-matter for anti-matter are all extremely small forces. In fact the force generated by a single electron is 10^40 larger. So any momentum that the condensed particles had would have overcome the force of repulsion and annihilations would have occurred. I will guess that somewhere between 75 to 90% of all matter would have been annihilated in the first couple of minutes after it condensed. This would have been the fireball that we call the CMBR. Now you ask where is all the left over anti-matter. I think it would have separated it’s self out into it’s own clumps of antimatter galaxies. We could be looking at an anti-matter galaxy far off and never know the difference. It would radiate just like a matter galaxy.

Sebby, how do we know that virtual particles don't tend to congregate in those parts of space that already has mass, the more mass the more virtual particles?
