[Asclepius]

... In effect, the stretching of space jiggles up some of the virtual particles and turns them into real particles ...

Yes. I've seen this happen in my seltzer water.

Akasha. Astral light. Ether. Nearly every esoteric tradition believes in some sort of proto-matter or not-quite-matter that suffuses the whole universe, every once in a while plunging itself into the grosser densities--that is to say, our world. In the Egyptian book of the dead the ether or the astral light has a distinctly dual character, with the Gods dwelling above in the rarified ethers; empty shells and ghost-forms and lost souls and abortions-of-darkness descending of their own weight to the grosser levels, i.e. our level, to taunt and torment us etc.

At last, physics is catching up with our Chaldean and Egyptian and Indus river valley forebears.

It's true. The more we know, the more we know we don't know.

[glorgau]

So in theory, an atom dropped down the exact centre of a vertical metal pipe should reach a terminal velocity as it ploughs through the viscous quantum vacuum, just like a ball bearing dropped into oil.

Perhaps this is where the constant c (the speed of light) arises. I don't have the spare time to do the ciphering (as Jethro Bodine would say) at the moment... :-)

[elbucko]

REALLY interesting post.
Thanks, Buck.

Perhaps another case of a scientific fact becoming known to be true long after stated by a religious leader.

One of those was by Muhammad who referred to the sun being the center of the solar system, even though Muslims denounced this until it was scientifically proven about a thousand years later.

The existence of ether in "space" was stated by Abdul Baha (of the Bahai's) about 100 years ago.

If folks used religion to open their eyes instead of close them, life on earth would be a whole lot sweeter.

[ConvictHitlery]

My calculations show that there is mistake here.

Time machines and endless energy

COULD we tap the quantum ether as a power source? The first consideration is how much energy it contains. Calculating it using quantum field theory, you get an enormous energy density-about 10110 joules per cubic centimetre ...

The figure should be 10E110 Joules, or 10^110.

[Physicist]

Some of the ideas that fell from favour are creeping back into modern thought, giving rise to the notion of a quantum ether.

Disingenuous. The quantum field is nothing like the "luminiferous ether". There's no implication of a preferred inertial reference frame, no notion of absolute velocity.

It's not clear, at least in this article, how Davies' ideas are any different from those of Feynman and Dirac. Leave it to The New Scientist to deliver the hype.

[lds23]

Just saw an interesting movie called "Donnie Darko".

Among other things, there's a theme around the multiple pathways through space/time and how they connect through wormholes.

Maybe not directly apropos to your post, but thought the folks on this thread might find it an interesting flick.

[scouse]

So the plenum cannot exert a frictional drag

Must consist of atoms of Teflonium. :^))

[Physicist]

Reactionary New Scientist hype bump.

(Is it just me, or is FR getting fuzzy, squishy and new-agey?)

[avg_freeper]

One of my favorite things to watch is a minivan driving around with a bunch of balloons inside. The van accelerates and the balloons swing forward.

Putting my knowledge of buoyancy and all aside it still looks like a cool "anti-pendulum".

[PoorMuttly]

Muttly want Quantum Ether.

Muttly have empty jar ready.

[Yeti]

IS SPACE just space? Or is it filled with some sort of mysterious, intangible substance? The ancient Greeks believed so, and so did scientists in the 19th century. Yet by the early part of the 20th century, the idea had been discredited and seemed to have gone for good.

Can't read past this. Ever heard of luminiferous ether? When, according to Einstein, gravity bends space, what is it bending? Nothing? How do you bend nothing?

Very annoying. I know some have said there is no ether, but its existence is assumed in most electromagnetic theory, relativity, etc..., and it has never, ever been "discredited."

[Consort]

It's a space-time matter-energy universe. Time is just the duration of movement and space doesn't exist. It's all matter and energy (plus thought and consciousness).

[RightWhale]

Michael Faraday

The one who upset physicists of his day and sparked Maxwell to devise his vector model of Electromagnetic phenomena. A simple experiment, a demonstration in the front of the lecture hall, and the revolution was off and running.

Michelson and Morley, sponsored by A. Graham Bell similarly upset the physics of their day. A simple demonstration, not small and inexpensive that time, though, and not in a lecture hall.

Could happen again.

[TigersEye]

Jimer has already found this but for the rest of you fans of mind bending experiences here's a bump.
