View Full Version : Confirmed: Matter = vacuum fluctuations

Matter is built on flaky foundations. Physicists have now confirmed that the apparently substantial stuff is actually no more than fluctuations in the quantum vacuum.

The researchers simulated the frantic activity that goes on inside protons and neutrons. These particles provide almost all the mass of ordinary matter.

Each proton (or neutron) is made of three quarks - but the individual masses of these quarks only add up to about 1% of the proton's mass. So what accounts for the rest of it?

Theory says it is created by the force that binds quarks together, called the strong nuclear force. In quantum terms, the strong force is carried by a field of virtual particles called gluons, randomly popping into existence and disappearing again. The energy of these vacuum fluctuations has to be included in the total mass of the proton and neutron.

But it has taken decades to work out the actual numbers. The strong force is described by the equations of quantum chromodynamics, or QCD, which are too difficult to solve in most cases.

So when this thing fluctuates . . .

Oh no! "We're in the Matrix!"

"So if the LHC confirms that the Higgs exists, it will mean all reality is virtual."

Is that the same thing as saying if one were a teeny tiny, microscopic organism, he would look at a fly swatter and say the holes are the size of Texas?

A fluctuating bowel creates brownian motion, which translates into brown mass.

Well, the guy says it poorly. Matter may start as a vacuum fluctuation, but once it gains sufficient energy it comes out of the virtual state into the state of real, long-lived particles.

Vacuum is by definition the total absence of matter. So we are now to believe that nothingness becomes somethingness because of a change in the nothingness?

I'm going to dust off my old SF books. They are at least semi-credible.

Your definition of the vacuum is outta date, Doc.

That would explain this:

I thought a vacuum was the total absence of atmosphere...my bad...

That's what used to be.

A vacuum is a complicated structure, much more so than previously thought.

The quantum foam continually vomits out new particles into the vacuum and then takes them back. Given quantum uncertainty, there is no such thing as a perfectly empty space even when you can't detect anything at all.

May the force be you, young padawan!

lol


Jes' so they don't try to seriously conclude that 'something' can come from 'nothing' - 'nothing' can not fluctuate, or it's 'something'.

Edit - again, the law of conservation of mass and energy is not violated, vacuum energy is a function of the universe since whenever it was created.

So ... are they saying that ... nothing matters?
or
Nothing is the matter?

I don't know about you guys, but I know that something is the matter when my quantum vacuum fluctuates. I quit buying those a long time ago.

Ashes to ashes
Dust to dust
quantum vacuums

It's starting to make sense, now!
