Dear young Physicists: Please, picture a frictionless Wheel that is lowered reversibly in Gravity

Posted by in categories: existential risks, particle physics

by Otto E. Rossler, Faculty of Mathematics and Science, University of Tübingen, 72076 Tübingen, Germany

When you are doing this picturing job, you will directly get close to Einstein’s heart. He only did not yet have this special sentinel available in 1907. Noether’s ultra-hard result of 1917 came 2 years in the wake of Einstein’s opus maximum that is being celebrated this year.

I need your kind help to improve on the following finding: “Noether’s Theorem + Einstein Equivalence Principle = c-global.” I have 5 steps to offer so far, the sixth would be your initiative.

Noether’s Theorem + Equivalence Principle = c-global (part IV, coda)

Posted by in categories: existential risks, particle physics

The retrieved global constancy of c in the equivalence principle implies that the vertical distance to the surface of the neutron star has increased compared to the traditional view: the indentation into the “cloth” of spacetime has become deeper.

The stronger the gravitational acceleration, the deeper the trough. The new globally constant-c result due to Noether implies that the spatial distance right down to the “horizon” (surface) of a black hole has become infinite. This novel spatial distance valid from the outside corresponds with the well-known infinite temporal distance valid from the outside for light sent down to, or coming up from, the horizon (Oppenheimer and Snyder, 1939).

So black holes are never finished in finite outer time. But I hear you ask: Is it not quite well known that one can fall-in onto a large black hole in finite astronaut time? Yes, this is correct.

How come? This is the last Noetherian point: The on-board clocks of the astronaut are infinitely slowed. Also our rotating wheel comes to a virtual standstill of its rotation on the horizon (the tangential velocity of the wheel staying invariant in reality while the wheel’s diameter invisibly approaches infinity).

Noether’s Theorem + Equivalence Principle = c-global (part III)

Posted by in categories: existential risks, particle physics

To see what happens, let your Noether wheel rotate about a horizontal axis (that is, rotate vertically). Then the doubled radius will still be optically masked in the horizontal direction, but not so in the vertical direction. Hence you get a 2:1 vertical ellipse.

The optical contraction in the horizontal directions, found to be valid downstairs using the Noether wheel, implies that light will be seen to “creep” downstairs at halved speed when watched from above. This is what Einstein already found in 1907. So everything is fine.

But: does light really creep down there? The answer is no. For the distance travelled is doubled compared to above.

Noether’s Theorem + Equivalence Principle = c-global (part II)

Posted by in categories: existential risks, particle physics

The conserved angular momentum L obeys a simple formula for a constant vertical (or else horizontal) rotation axis of the wheel:

L = ω m r^2

Since this expression is hard to remember by heart, the word “L’hombre” can help even though it is not high-Spanish. ω is the rotation rate, m the mass and r the radius of Noether’s frictionlessly rotating bicycle wheel.

If ω is halved (as on the surface of a neutron star), what about m and r , the other two components of the conserved L ?

Noether’s Theorem + Equivalence Principle = c-global (part I)

Posted by in categories: existential risks, particle physics

This simple insight amounts to a revolution in physics. It resolves an inconsistency accepted by Einstein in the absence of Noether’s theorem in 1907: that c were reduced downstairs in a constantly accelerating long rocketship in outer space.

Noether allows you to see what happens. She discovered “global conservation of angular momentum in nature” as is well known in 1916.

Take a frictionless bicycle wheel that is suspended from its hub, and lower it and then pull it back up again. What happens if angular momentum is constant all the time as she showed?

Answer: The rotation rate of this “clock” must go down reversibly like that of any other clock. But since angular momentum is conserved (Noether), the other two components in angular momentum besides rotation rate (i.e. mass and radius) cannot both remain unchanged.

This is a wonderful new result enabled by Emmy Noether.

Many people have ceased to claim that “thinking helps” as Hewlett-Packard say

Posted by in categories: existential risks, particle physics

I have simple thinking in mind – like visualizing a rotating wheel suspended from its hub without friction so it can be pulled up and down easily.

You can trust that angular momentum remains constant (nature has a knack for that). But the wheel is also a clock. So if you lower it, it must go slower down there and become faster again when retrieved. It thus makes for a beautiful mental plaything (a “hot” one as the young people would say). Angular momentum can be called “L’hombre” (a macho word which is not quite right in Spanish). Can you feel L’hombre in your hand while moving up and down your toy in your mind?

The word “L’hombre” allows one to remember “L = ω mr^2 ” for angular momentum L in one’s mind forever. Omega (or ω) is the rotation rate, m the mass of the wheel’s rim (with a virtually weightless hub for simplicity), and r is the radius. So the wheel is now transparent to us like glass, right? What happens if ω is halved for simplicity as on a neutron star?

Either m must be doubled, or else r must be increased by square-root 2, or both m and r must have changed somehow in a compatible manner. How about m halved and r doubled?

Constant Tangential Speeds of Wheels are global Constants of Nature up to c

Posted by in categories: existential risks, particle physics

This new principle ( http://eujournal.org/index.php/esj/article/view/814/876 ) is implicit in special relativity’s equivalence principle including gravitation.

Therefore, c is a global constant of nature again. Hence no Big Bang (I hear you laugh) and no Hawking radiation (silence) and no CERN safety (fear).

Ten thousand CERN physicists agree through their roaring muteness for 7 years.

Only a member of the young generation could help. But the young are no longer free to speak up since they are no longer protected by their advisors.

The Science of Cryodynamics proved that there was no Big Bang: Why create one on Earth?

Posted by in categories: existential risks, particle physics

There are quite a few publications on cryodynamics in refereed journals since 2011. Cryodynamics is the sister discipline to thermodynamics and is crucial for the control of sustained hot fusion in Tokamak reactors. So it has become the basic science for an energy-thirsty planet. As a side effect, cryodynamics proved Zwicky’s “tired light” hypothesis correct. So there was no Big Bang.

CERN, however, tries to create the first Big Bang on earth. Why is no one asking it to first renew its by 7 years outdated “Safety Report”?

I append a link to the first paper on cryodynamics: http://www.complex-systems.com/pdf/20-2-3.pdf
