the Unruh effect: quantum mechanics meets relativity

[scruffy]

This is very cool.

I keep saying there's no such thing as "nothing". This proves it.

The Unruh effect describes the effect of relativity on quantum mechanics.

At zero temperature, quantum particles are still constantly popping in and out of existence.

How much of that you SEE though, depends on how fast you're moving.

Measuring the Unruh effect: Proposed approach could bridge gap between general relativity and quantum mechanics

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their novel approach opens new possibilities for exploring fundamental physics and for developing...

"In quantum theory, even the vacuum seethes with tiny energy fluctuations, where particles and antiparticles briefly appear and vanish. Remarkably, the Unruh effect shows how these 'vacuum ripples' are perceived depends on the observer's motion. A stationary observer sees nothing, but an observer undergoing acceleration perceives them as real particles with a thermal energy distribution—a 'quantum warmth,'" said Noriyuki Hatakenaka, professor emeritus at Hiroshima University."

The Unruh effect makes clear that "nothing" is a PERCEPTUAL condition, it has nothing to do with reality. You only "see" thermal activity when you're moving fast enough.

So you think a cat inside a box is in some state between "living" and "dead" ... the article is behind a paywall, but it sounds like Schöndinger's Paradox all over again ...

If you have motion, then you have kinetic energy ... therefore you don't have zero temperature ... per Boltzmann's Law ... never mind 3rd LoT ... "pie in the sky / go to heaven when you die"

both Unruh and Schrödinger are German words

Unruh is 100% Dutch ... you Kartoffel don't use the /-uh/ suffix ...

Oh excuse me ... I forgot how sensitive Germans are about gender equality ... die Kartoffel ... sheesh ...

Emanations from the fourth spatial dimension. This is also what explains Indeterminacy, which is irrational and impossible without an outside source actually determining what is happening.

You're missing the point.

The temperature that you SEE (measure) depends on how fast you're moving.

Yes ... that's the kinetic energy definition of temperature ... just in reverse ... how are you accounting for the latent energy in state-of-matter changes? ...

Slow down. So, at 0 velocity, you measure 0 temperature and see no particles.

But at high velocity, you measure a positive temperature and you see particles.

Both of these conditions must exist simultaneously. A stationary observer and a moving observer must be able to inspect the same sliver of spacetime.

In one condition you have no kinetic energy, and in the other condition you have a positive kinetic energy. The two conditions must exist at the same time. What does that tell you?

I'm currently at zero velocity with respect to my computer screen ... temperature is 58ºF ... I see my computer behind the cat ... just closing my eyes doesn't cause acceleration ...

Your premise is obviously wrong ... temperature is the measure of kinetic energy of the particle ... you seem to have cause-and-effect backwards, and that's because you're repeating the definition of temperature backwards ... if the particle is stationary and we're moving is the same measure as we being stationary and the particle is moving ... and remember, time dilates the same either way ...

For the cause of no particles (a perfect vacuum), we have the effect of 0 kelvin measurement ... the above should be stated "with 0 velocity [zero energy], we have no particles and see 0 temperature" ... only with zero energy (and thus zero matter) can we see zero temperature ...

You should probably answer Sage's post #5 before you answer me ... measuring temperature requires particles be introduced into your environment ... thus your "zero" measure is physically impossible ... and besides, does a stationary photon even exist? ... and how do we define "existence" with words that depend on the definition of "existence" ... Catch-22 ...

The cat in the box is either "all alive" or "all dead" ... Miracle Max lied, there's no such thing as "mostly dead" ...

Virtual particles are not actual particles, they are an abstraction, an interpretation.

The Only Thing My Cat Is Not Confused About Is Whether She's Alive

Quantum Quacks come up with jerryrigged explanations. For example, they claim that a particle of antimatter and a particle of matter are suspended in a frozen state just before they would reach the final stage of annihilation into pure energy. That state produces an apparent Nothingness. And before they reach that state, or when they separate, is Somethingness: matter.

And by the way, if minus one plus one equals zero, and antimatter plus matter equals zero matter, then the square root of minus one is antimatter.
