New (To me) simple idea behind Quantum Double slit experiment
How do you get from this to the math of interference? How do you test that this is the correct model?

What problem does this solve, that isn't already addressed?

Gravitational wave generation of integrating blackholes
"An artist's impression of gravitational waves from two orbiting black holes." This shows the black holes and the gravitational waves, not black holes as waves.

And there is no phase involved in this. Where did you get this drawing?

Gravitational wave generation of integrating blackholes
Then what is “since the falling spiral of the two would be 180 degrees out of phase, would not the resulting gravitational wave represent only the difference in mass of the two?” referring to? The gravitational waves do not undergo a “falling spiral” (and it’s gravitational wave; a gravity wave is something different) The phase relationship of what? There is no combination of waves here.

What is really the total energy of particle? Also an interesting physical quantity f = mc^2/h
Then it doesn’t matter, since the energy appears on both sides of an equation. The energy wouldn’t be something you can convert to other forms. How would you test to see if the energy existed? Electrons and positrons can form positronium, with a ground state of -6.8 eV, which classically corresponds to a KE of 6.8 eV and a PE of -13.6 eV. This would not give you a high-speed electron or positron. Published in Physics Essays, which is known to publish crackpot material. I’ve done experiments where radioactive potassium isotopes were held in a magneto-optic trap, meaning they had almost no KE - the residual speeds would be a few cm/s - and they underwent decay.

What would the phase of the spiral have to do with anything?

Rest energy was derived in one of Einstein’s 1905 papers Inconsistent with e.g. electron-positron annihilation Evidence? Some particles that “participate” don’t even exist before the decay occurs Citation?

Why do ordinary people travel with airplanes ?
1. It’s not up to you, and 2. “normal” is overrated

Not if you’ve learned some quantum mechanics

New (To me) simple idea behind Quantum Double slit experiment
This is not an experiment That’s an aphorism, not actual physics, and applies to macroscopic systems. The concept of pressure from kinetic theory doesn’t work at the subatomic level. That speaks to your understanding, which carries no weight.

Consequences of raising salaries...
https://newrepublic.com/post/175598/gm-ceo-mary-barra-30-million-salary-uaw-strike “[GM CEO] salary has increased 34 percent over the last four years, while in four years workers’ pay has only increased by 6 percent. Under the current contract, the $18 per hour starting pay for autoworkers is about 36 percent below where it would be if the 2007 starting wage had kept up with inflation.” (average inflation from 2007-2020 was about 2%

What experiment would confirm this? But consistent with experiment. When photons or electrons are sent individually through a double-slit, you eventually get an interference pattern.

Calculate acceleration given only distance and time
OK, it’s not identified as a roller coaster, and the implication is that you are starting from rest. You can use s = 1/2 at^2

Calculate acceleration given only distance and time
Can you post the entire question, verbatim, please?

Let's start at the beginning?
No. Temperature is a measure of the average kinetic energy of the particles in a substance. Photons are emitted by hot objects, with the spectrum depending on the temperature. You are referring to the time of last scattering. Photons existed before that time. They just didn’t travel very far before interacting.

Consequences of raising salaries...
In addition to my previous post, one should also note that auto workers took a pay cut when automakers struggled during the great recession “the UAW agreed to $11 billion in labor cuts, twenty-one thousand layoffs, a wage freeze for workers, a tiered wage system for new workers, a no-strike agreement until 2015, and the transfer of retirees’ health care and pension benefit costs from GM to the UAW, in order to save GM $3 billion. The union is still fighting to regain the ground they lost from these concessions.” https://jacobin.com/2023/09/united-auto-workers-uaw-strike-big-three-automakers-stock-buyback-shareholders

Do you consider Police Auditors to be ethical or unethical?
Anecdotes are not evidence. It should be expected that some auditors have police records, because a random sampling of the population will include people with police records. For your allegation to have merit, you would have to show a statistically significant deviation above the expected fraction*. If there are few auditors, as you have alleged, such a deviation could just be an artifact of a small sample size. Without knowing how many auditors there are, you can’t establish the fraction that have records. And there could be bias, because auditors might get arrested without a legitimate basis, owing to police overstepping, or due to attempts at intimidation because they don’t like being filmed. I’ve seen videos with such threats of arrest. * one-third of working-age men https://www.personnelchecks.co.uk/latest-news/criminal-record-checks-increasing#:~:text=Data from the Ministry of,someone with a criminal conviction.

Evaporative Coolers Vs A/C Cost Effectiveness
The anecdotes I’ve run across for why heat waves are such an issue in Europe is the lack of AC. In the US it’s lacking the electrical capacity to run all of the AC And we fought a revolution so we don’t have to. Got rid of most of those superfluous vowels, like the u in colour or flavour.

SAILING TO THE STARS WITH NUCLEAR
It’s not only an issue of energy, but having a reaction mass to expel*. The longer the period of acceleration, the more mass you need, and this is inefficient because in the beginning, you’re accelerating all that mass. *unless you use photons, which is really inefficient

Do you consider Police Auditors to be ethical or unethical?
There have been numerous instances in the US of police summaries being in conflict with subsequently shared video evidence. In short, police will lie to cover their 6. Mandating body cameras has been one push to mitigate that, which would reduce the need for citizens to “audit” If the police are following the rules, they should not have any valid objection to being filmed. They’re supposed to be serving the public. The public has the right to film them in the US; there’s no ethical problem that I can see. Evidence?

A contradiction?
The issue is that you are mixing two distinct effects. One is the acceleration of freefall, the other is closing speed, as Janus has explained
