Quantum Effects Observed in Cold Chemistry

ScienceDaily (Oct. 11, 2012) — At very low temperatures, close to absolute zero, chemical reactions may proceed at a much higher rate than classical chemistry says they should -- because in this extreme chill, quantum effects enter the picture. A Weizmann Institute of Science team has now confirmed this experimentally; their results will not only provide insight into processes in the intriguing quantum world in which particles act as waves, but they might explain how chemical reactions occur in the vast frigid regions of interstellar space.
Long-standing predictions are that quantum effects should allow the formation of a transient bond -- one that will force colliding atoms and molecules to orbit each other, instead of separating after the collision. Such a state would be very important, as orbiting atoms and molecules could have multiple chances to interact chemically. In this theory, a reaction that would seem to have a very low probability of occurring would proceed very rapidly at certain energies.

Dr. Ed Narevicius and his

Dr. Ed Narevicius and his team in the Institute's Department of Chemical Physics managed, for the first time, to experimentally confirm this elusive process in a reaction they performed at chilling temperatures of just a fraction of a degree above absolute zero -- 0.01°K. Their results appeared this week in Science.
"The problem," says Dr. Narevicius, "is that in classical chemistry, we think of reactions in terms of colliding billiard balls held together by springs on the molecular level. In the classical picture, reaction barriers block those billiard balls from approaching one another, whereas in the quantum physics world, reaction barriers can be penetrated by particles, as these acquire wave-like qualities at ultra-low temperatures."

If I may illustrate my comments on time. There is relative motion between atoms and motion requires the use of time as a dimension. Quantum effects within atoms do not require time to describe. Therefore they do not "slow down."

"There is relative motion

"There is relative motion between atoms and motion requires the use of time as a dimension"

That's what time IS, in case you weren't paying attention. Time is simply the measuring stick for describing the motions of the universe relative to us. It quite definitely exists, in the same fashion as length and width.

"Quantum effects within atoms do not require time to describe. "

Quite the opposite. They require infinitely more time to describe than to happen.

"Therefore they do not "slow down.""

Time is relative. If they appear to slow down, then they've slowed down relative to us.

But it isn't quantum effects that slow down anyway. Actually this doesn't talk about ANYTHING slowing down. It talks about quantum effects speeding up chemical reactions by removing non-quantum barriers. Did you even read the article?

Should I detect a photon that first came into existence at bang time, no time has passed between its creation and detection. Traveling at the speed of light the amount of time that passes is zero. The admitting and absorbing atoms are separated only by distance as ALL reference frames are equally correct. The one without the passage of time is also correct.

If the amount of time that

If the amount of time that passes is 0 then why does it take billions of years for light to reach us from a galaxy billions of light years away?

The truth is that time exists as soon as there are two or more entities which are moving, relative to each other. Time passes even at light speed.
Time even exists at the quantum level when observers are involved.

All reference frames may be correct, but they are not identical. None have been observed which are timeless. Even a photon that first came into existence didn't exist before that.

1) If all laws are the same in all reference frames and there is a valid reference frame without time then distance can be described without time.

2) As the big bang started as an infinitesmal point which expanded then the bang occurred at every point all of space as it exists today.

3) The photon which was emitted at time time after the bang which we observed as cosmic background is observed as lower in frequency because of this same expansion.

4) In our reference frame the distance became greater with expansion but the time between emission and observation remained zero.

Therefore we are observing the expansion which we can also express as time.

Nothing new here at all. This is not new science. This is Damn You, HG Wells! The universe is not Minkowski space. It is assuming time is a dimension starting at a zero and continuing smoothly that causes all the confusion in trying to make sense of it. Time simply does not apply to most quantum phenomena.

The slit experiments for wave and particle. Single photons at random times still behave as a wave. How do the photons "know" what happened at different times? No problem there at all unless we falsely assume time is a consideration to quantum effects. It is just a matter of looking at it wrong that makes it confusion. That is why I first posted this under philosophy not science. It is just a matter of looking at things wrong that causes the confusion.

1: IF, maybe. But as yet

1: IF, maybe. But as yet noone has observed a state without time, so the point is irrelevant and not worth discussing.

2: Prove it.

3: And the only reason we see it at all is because it is affected by time the same as everything else. Wait 5 billion years and the cmb won't exist anymore.

4: False, it was approximately 13 billion years between transmission and reception.

Do you imagine time passes between the emission and absorption of the photon? If so why is the reference frame of the photon different from other inertial reference frames? How does a photon traveling at c where t -> 0 experience 13 billion years? All that happens to it is stretching as the distance between emission and absorption points became greater.

If the CMB disappears does that not require energy to be destroyed?

Do you imagine time doesn't pass between the emission and absorption of the photon?

"If so why is the reference frame of the photon different from other inertial reference frames?"

You don't know what the reference frame of a photon is, so you're in no position to make claims on it.

"All that happens to it is stretching as the distance between emission and absorption points became greater."

Without time and space there wouldn't be any streching, proving yet again that time affects even photons.

"If the CMB disappears does that not require energy to be destroyed?"

No, it requires sufficient time to strech so far as to be undetectable and overshadowed by local phenomena.
