Abstract
But if so, it means the end of earth soon. This frequently published result is contradicted by no one in physics. The lobby just bets on the media remaining quiet.
It is ironic that so many physicists take their children hostage. This is because the media do not ask them why they are not afraid. For then they would start to stutter and their children would begin to ask questions. Even Stephen Hawking could no longer afford to skirt the issue.
The ultimate reason, of course, is Einstein. He alone can help. The “happiest thought of my life,” as he always said, has a further consequence (c-global). Ask your teachers about it. You will learn they have no idea. This is at the root of the problem: irrational dogmatism. Worse to date than in the middle ages because the consequences do not hurt a minority of women: this time around everyone is the victim.
The poor witches on the stakes probably foresaw it all since no one else had a closer look at the nature of human society. So only in Auschwitz later on, after the doors were closed. Please, do change your attitude, poor consensus-based society without a heart: Why not show the world that you love your children, my dear physicist colleagues? Do stand the trial that you are under in the face of a watching globe!

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.

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).

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.
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 ?

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.
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?
