  1. And there is no phase involved in this. Where did you get this drawing?
  2. 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.
  3. 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.
  4. Black holes are not waves
  5. What would the phase of the spiral have to do with anything?
  6. 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?
  7. 1. It’s not up to you, and 2. “normal” is overrated
  8. Not if you’ve learned some quantum mechanics
  9. 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.
  10. 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%
  11. 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.
  12. A summary would be appropriate. You can post excerpts, as necessary.
  13. 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
  14. Can you post the entire question, verbatim, please?
  15. 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.
  16. ! Moderator Note We’re a discussion forum. This is soapboxing, which is against the rules. You’re free to wonder out loud about how you would run the world if you were in charge. Just not here.
  17. 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
  18. 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.
  19. 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.
  20. 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
  21. 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?
  22. 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
  23. New NASA report just dropped https://science.nasa.gov/science-pink/s3fs-public/atoms/files/UAP Independent Study Team - Final Report_0.pdf "At this point there is no reason to conclude that existing UAP reports have an extraterrestrial source."
  24. Evaporative coolers only work in low-humidity areas, but where they work, and water is available, sure, people should use them.
  25. Snopes concludes it’s a fake, so if that’s correct, this is moot https://www.snopes.com/fact-check/titan-sub-transcript/ “Efficiency and brevity were a priority. There was absolutely no chitchat (such as "Enjoy the dive, gentlemen"). Often, the actual exchanges even omitted the verb, newspaper headline-style ("Bottom time up"), to save time and typing.” Scroll to the end to see all of David Pogue’s analysis (correspondent who went on a dive, and so has first-hand knowledge)
