  1. Well, no. Unless you can show where SR disagrees with experiment, under a situation where it applies, there is no basis to claim that it’s incorrect. Why bother, when current time transfer experiments show your idea to be wrong? People do “common view” observations of GPS satellites to tell what time it is. If the satellites had errors between zero and a few hundred nanoseconds, depending on the location when they were calibrated using D/c for the time delay, this would not be possible. The GPS clocks would not be synchronized if relativity was wrong.
  2. A test would be a physical experiment. That would be all that current physics explains.
  3. ! Moderator Note Let’s keep the criticism focused on the science
  4. GPS is at a lower orbit, but the same principle applies. GPS satellites at different positions in the sky would give errors in positioning owing to this discrepancy, depending on the time of day they were synchronized with the ground station. Tens of meters is a big error. Has anyone noticed?
  5. The specifics of the mechanism might be missing, but it clearly states that the jets arise because the system needs to shed angular momentum. (that was an epiphany for me when I first learned it)
  6. We are dealing with a specific idea with its own predictions. Other theories are irrelevant to to conversation. I did not posit clock rate changes. I am focusing on the transit time that is predicted by this idea. The time-of-flight would deviate from D/c in a predictable way. Their predictions are based on there being an absolute frame. I am endeavoring to show that the calculations do not match observation, and was asking for observations that match prediction, which is a requirement, and not at all unreasonable.
  7. But what if D were ~35,000 km? You send a signal to a geostationary satellite and back to the source. The error is now almost a microsecond. When the satellite is in the opposite direction, it’s that much, but in the opposite direction. Wouldn’t we notice this happening? The source clock, good to much better than a nanosecond, being almost a microsecond off by more or less than expected?
  8. Have checked the curriculum at this type of school? They might list their textbooks and/or provide a syllabus for each course.
  9. You don’t need to understand the math to use the result, so “people” don’t need to understand the math, but in order to create the model, you need to understand the math. You have to quantify the effects and have a formula that describes the various interactions and processes. Or you can go with a boolean system, with a series of yes/no questions to be answered, which could be laid out in a flowchart. But you need to have a comprehensive list of questions and cover all of the possible situations. It might be helpful to learn a little bit of game theory

  11. Under what conditions is it tens of picoseconds?
  12. How does one test to see if your ideas are wrong? This would seem to require math.
  13. GPS may be complicated, but it was designed to work using Einstein’s relativity. If that’s wrong, GPS wouldn’t work. And yet it does…
  14. Clock signals between separated atomic clocks. You tell me - it’s your conjecture. According to your equations, the propagation time would vary, so a GPS clock being synchronized at one time of day would have a different delay than at another time. The system would have to account for this so that the GPS clocks could all show the same time. Is there any evidence that this is the case?
  15. If you mean like the K-T impact, then no. Species go extinct all the time by evolving into a new species. Various species of Homo (e.g. Homo habilis, or H. neanderthalensis) are extinct, but there was no “event” that killed them off.
  16. That would be the case if the universe were static, but the universe is expanding
  17. I don’t know in detail how Chinese submarines work, but I doubt the battery runs the main propulsion system. That requires a lot of power, and is likely run directly from a steam turbine. The battery might run a motor used in emergencies, when main propulsion is unavailable, capable of a few knots. If the primary propeller(s) became fouled, the emergency propulsion might be engaged, which likely has its own propeller. Different cultures place different emphasis on safety, and space is usually at a premium on a sub. And mistakes can be made. The US has safeguards and procedures put in place only after incidents revealed flaws, because sometimes they reveal flaws that don’t show up under normal ops, and are situations that you wouldn’t test for because it would be too dangerous to do so. e.g. There were significant changes made after the Thresher was lost in the 60s. https://www.usni.org/magazines/proceedings/2020/october/reflections-loss-thresher#:~:text=After the Thresher disaster%2C the,quick actuation in an emergency.
  18. Batteries are a storage medium. The power comes from the reactor under normal operations. Batteries will supply a limited amount of power in case the reactor is scrammed. 2.6 MWh is not a lot of energy when considering a reactor that produces a full power of ~100 MW.
  19. Who is “we”? Density is m/V if mass has units of kg, and volume is expressed in m^3, the units are kg/m^3. Or you could use grams/cm^3 No numbers. They aren’t necessary. This is a “you” problem. Stop blaming physicists.
  20. The radiation we detect dates from the recombination epoch, ~380,000 years after the big bang.
  21. If there was an absolute velocity we should see a diurnal effect in clock signals, since at noon we would be traveling at a different absolute speed than at midnight. The effect should also show an even larger fluctuation over the course of the year, from the change in orbital velocity. Do you have evidence of this?
  22. k has units. you just don’t know what they are. That’s not the same thing. Like when you see 2x = 5, you don’t know what x is until you solve the equation. It doesn’t magically become 5/2 only when you solve it. There’s no time dependence here.
  23. A gravitational field contains energy. Energy is a source of gravity.
  24. The danger right now is people being too credulous and thinking that AI is actually intelligent and not some fancy predictive text algorithm.
  25. The ISS is only about 400 km above the earth, which has a radius of about 6400 km.
