1. ## The nature of light and the size of the Universe.

You won't find any redshift in 60 seconds. The light from the Sun goes for 8 minutes, is there a red shift in the spectra of chemical elements????
2. ## Raspberry Pi controlling an electronic latch - Electronics help

check whether the output power of the dc-dc converter matches the power consumption whether it is very hot
3. ## Fundamental Quantum Mechanical relations

In general, the main thing in QM is the uncertainty principle formulated by Heisenberg. It means the rejection of complete determinism in the laws of physics. And this is correct, because if there were only determinism in the laws of physics, that the fate of each person would be predetermined even at the time of BB.
4. ## Can infinities exist in nature?

The big Bang created Our Universe, which is part of the Multiverse or proto-Universe. And the Multiverse is truly infinite.
5. ## New theory of the speed of light

And if you answer the question, " why is the geometry of our space-time like this?" Because not only do we not have an absolute reference system (Newton's ether) , but we also do not have absolute standards of time and distance. These standards change so that the speed of light remains constant.
6. ## Planck's constant and wave impedance of vacuum

7. ## Planck's constant and wave impedance of vacuum

I noticed that the wave resistance of the vacuum is in some sense equivalent to the Planck constant where e is the elementary charge, alpha is the fine structure constant, and Z0 is the vacuum wave resistance What does this mean?
8. ## Gravity speculation

A little bit wrong. Space-time repels both matter and itself. Matter attracts both matter and space-time, or holds space-time around it. In other words, the mass of matter is positive, and space-time mass is negative.
9. ## Does Classical Gravity exist in the "atom."

It exists, but it is very weak. More than 40 orders of magnitude weaker than the electromagnetic interaction
10. ## Curved coordinates and the frame of reference that applies to them

You don't have to. But setting the origin of the coordinate system to the center of mass dramatically simplifies the mathematical description of the gravitational field, since the problem becomes centrally symmetric
11. ## Hydrogen burning inside a nitrogen atmosphere

The Haber process is an industrial process (invented by Fritz Haber and Karl Bosch) in which atmospheric nitrogen is "bound" by the synthesis of ammonia. A mixture of nitrogen and hydrogen is passed through a heated catalyst under high pressure[1]. At the same time, due to high pressure, the equilibrium in the N2+3H2 ⇄ 2NH3 reaction shifts towards ammonia. The firm BASF has been studied more than 8,000 catalysts of the process. Already in 1910, it was shown that the best catalyst is fused iron with additions of aluminum, potassium, and calcium oxides. This catalyst became the main one for the synthesis of ammonia for 90 years.
12. ## Phosphine detected on Venus

Scientists have found another sign of life on Venus – the simplest amino acid glycine. https://arxiv.org/abs/2010.06211
13. ## Can you be a scientist and still believe in religion?

I saw a video on YouTube where a priest, who is also an associate Professor of physics at Moscow state University, proved that God did not violate the laws of physics when he created the Universe. "God first created the Universe, and only then the laws of physics, and the law has no retroactive force." You can laugh, but our world is sinking into obscurantism.
14. ## GRAVITY: Force or Farce?

The deflection of light rays by the mass of the sun was twice as large as predicted by Newton's theory. Einstein's theory explained this (although an alternative explanation has recently been found for this effect within the framework of a small analogy of Newton's theory). In addition, Einstein's theory explained the precession of mercury's orbit, and here no alternative explanations have yet been found.
15. ## GRAVITY: Force or Farce?

By the same influence, we mean the same acceleration. In this case, the force acting on the body is proportional to its mass, and the acceleration of the body is inversely proportional to its mass (Newton's second law). Thus, the mass of the body is reduced and it turns out that the acceleration of the body does not depend on its mass.

17. ## Invariance of the speed of light

The keyword is "directly". It is affected by the Planck constant, which is uniquely related to the speed of light. Planck's constant also determines the size of the atoms, hence the size of the physical artifact.
18. ## Invariance of the speed of light

To measure the dielectric and magnetic constants, a distance standard must be used. Is there a distance standard independent of the speed of light? The whole problem of invariance of the speed of light comes from the fact that there are no standards of distance and time independent of the speed of light in a vacuum. But the dielectric and magnetic constants will change differently when the speed of light changes, so we can detect a change in the wave resistance of the vacuum.
19. ## Hijack from What does it mean that physics it time/CPT symmetric?

I agree. Nonsense is not nonsense, and the proof of a parallel universe can not be considered. The anomalous signal could have come simply from outside the Universe. Or even its source was in the earth's crust.( There have been reports of a heat source under Antarctica's glaciers) But the statement about a parallel Universe was made by NASA, why did they need it?

21. ## Hijack from What does it mean that physics it time/CPT symmetric?

Biology can simply be explained. All living matter on Earth came from a single RNA molecule that was accidentally formed.
22. ## What does it mean that physics it time/CPT symmetric?

And how then to be with symmetry? I don't see any other option, except that the universe appeared together with the anti-universe, which consists of antimatter and electrodynamics in it works on the left-hand screw rule, while in our case it works on the right-hand screw rule.
23. ## What does it mean that physics it time/CPT symmetric?

I wonder if there is a force similar to the Lorentz force for gravity? Its existence would violate the symmetry. For a proton, the magnetic and mechanical moments are directed in one direction, and for an antiproton, they are directed in the opposite direction.
24. ## The idea of the nature of time dilation. Can be checked.

If you go back to the experiment you referred to, when the couple left the atomic clock at home and went up the mountain with other clocks. With a 99.99% probability, the atomic clock left at home did not use radioactive decay, but was a caesium quantum frequency standard. I wonder in which country you can freely buy a device that uses at least 1 milligram of a radioactive isotope. Therefore,it would be very interesting to conduct the experiment that I suggested earlier. We calculate the number of decay events for a trillion periods of oscillation of the quantum frequency standard at one height, and then at another height, and compare.
25. ## The idea of the nature of time dilation. Can be checked.

There may be another explanation for the results of the experiment. An increase in frequency at the bottom can be combined with a slowdown in time at the bottom ( with a slowdown in the course of processes, including radioactive decay)
