@sonhouse saidReminds me of the Casimir effect and vacuum energy. Stuff pops in and out of existence to cause it.

New theory of the expansion of the universe does away with the need for those two in favor of singularities popping in and out of existence too fast to be noted but causing the expansion and density of the universe.
So they next have to find experimental support.
Others have used this unprovable stuff to explain other things as well. The creation of virtual particles near the event horizon of a black hole was hypothesized by physicist Stephen Hawking to be a mechanism for the eventual "evaporation" of black holes.
People are going to try to resolve Bentley's paradox with creative ideas. A zero-energy universe is one I found interesting.

@Metal-Brain saidThe Casimir effect is known and measurable and PROVEN there is a background of particles going in and out of existence.

So you saying unprovable just indicates how much you dislike science.
We KNOW when conjecture is unprovable, the existence of GOD is unprovable, no god comes down to prove itself.
Which is because religions are ALL man made and some really NEAT scientific conjectures abound like string theory which so far has no way to make experiments to prove or disprove.
But these kind of conjectures are what advances science, ESPECIALLY if they are disproven, that makes one less conjecture known to be wrong so the search for the Theory of Everything goes on.
AND technology advances year by year so experiments thought impossible 10 years ago is now possible and experiments NOW thought impossible can by reality in another 10 or 20 years so the search for truth goes on.
@sonhouse saidI never said that. Go back and read what I wrote and not what you assumed I wrote. I didn't say anything to offend you yet you are coming across as e jerk.

I think you are holding a grudge because of unrelated discussions from the debate forum. You hate any political opinion other than you own. This is the science forum. Let go of your political hate.

Just after mentioning Casimir effect, implying that too is unprovable.
If that is not what you meant you should have made that more clear.
The Casimir effect is getting to be a pain in the ass for quantum physics because they deal with the extremely small and any particles close together feel that force which alters quantum effects sometimes negatively.
So they have to study Casimir and learn how to factor it out when they are dealing with stuff ten or twenty angstroms apart.
@sonhouse saidCasmir asserted singularities pop into and out of existence?

Nope. Not singularities. Just like I told you in the past, Hawking has no confirmation his hypothesis is valid. Like string theory he had no way to test that hypothesis and it is still impossible.
And the reason for the results of the Casmir effect are still disputed. Look it up. There are still disagreements as to why the experiment worked. Show me the evidence of the virtual particles popping in and out of existence. Prove it.
@Metal-Brain saidAnd when did Cassy do that? Oh yeah, 1948. close to EIGHTY years ago. If you haven't noticed, there has bee some advancement of science and technology in that span of time. Very minor advances of course..........

@Metal-Brain saidIt's basic quantum theory.

@Metal-Brain saidYou continue to play your intellectual lazy game. You can google it as well as I can.

YOU are the one asking, not me.
@sonhouse saidI already did. Look at possible causes.

Your MO, What is your source of information.
You must have said that a thousand times.

@Metal-Brain saidI think it's the other way around. A vacuum just has energy in it already, and it's that energy that gets converted into virtual particles. Of course, energy and mass are equivalent because E=mc^2, so I suppose it doesn't really matter if it's virtual particles that give empty space its energy, or vice-versa.
Reminds me of the Casimir effect and vacuum energy. Stuff pops in and out of existence to cause it.
Physicists don't really know what space is, though, which is telling enough.
@Soothfast saidSpace does not have mass.

@Metal-Brain saidSpace can contain energy, and because of quantum fluctuations of a sort, that energy can be converted into fleeting particle-antiparticle pairs that almost immediately mutually annihilate. Virtual particles.
Space does not have mass.
From https://en.wikipedia.org/wiki/Zero-point_energy:
"According to quantum field theory, the universe can be thought of not as isolated particles but continuous fluctuating fields."
And then from https://en.wikipedia.org/wiki/Field_(physics):
"In the modern framework of the quantum field theory...a field occupies space, contains energy, and its presence precludes a classical "true vacuum". This has led physicists to consider electromagnetic fields to be a physical entity, making the field concept a supporting paradigm of the edifice of modern physics."
@Soothfast saidYes, but it does not have mass.
