  1. An empathy deficit could be from being a sociopath, though. It’s tough trying to diagnose people outside of a clinical setting. Yup.
  2. Are you quoting this from somewhere? Somewhat predictable. Hydrogen masers’ drift has a component due to aging of the coating of the maser bulb, and my understanding is that it’s somewhat unpredictable in how it varies. You determine it by comparing to other clocks. “constant environment” would be things like temperature and humidity
  3. Drift is a specific noise process in timekeeping. Time dilation is not drift. The frequency shift is the source of the time dilation (you integrate the frequency shift to get it)
  4. “hardly” is a matter of the precision of the clocks. The value given here is 3 x 10^-10, which is pretty big in atomic clock terms. A millisecond per year (3.15 x 10^7 sec) https://www.newscientist.com/article/2085599-earths-core-is-two-and-a-half-years-younger-than-its-crust/
  5. No, this is incorrect. Because you need to keep all the clocks synchronized, and this is done via a ground station, so the clocks need to run at the same rate as UTC(USNO), which is the source of GPS time A nanosecond of error is a foot in positioning
  6. I don’t understand. If the efforts are ongoing, where does the level of commitment come into play?
  7. I would say no Indeed. The problem is with society's attitude. I don't know. Are the efforts for curing or preventing?
  8. If they aren't sick, why do they need a cure?
  9. Are you prepared to discuss the engineering difficulties of this? If not, you're just offering science fiction. The devil's in the details, which you are not presenting.
  10. ! Moderator Note Chatbots are not reliable technical resources. This response is horrendous. If you want to discuss the errors, you should make that clear. (that's true in general for your posts: make clear what you wish to discuss)
  11. I’m not going to watch a 1:47 video to parse the context of the statement.
  12. It’s a dangerous thing when people give pop-sci explanations, and from it people think they understand the underlying science.
  13. As I said, your analogy is exaggerated. Some of us understand how a finite c works, and your example ain’t it.
  14. This suggests you don’t know what entanglement is, or what was being proposed. How do you entangle space? What properties would be entangled? How would entanglement create spacetime?
  15. Yes. We know this. Is there a problem? (other than the difficulty in seeing through our galaxy)
  16. ! Moderator Note Links are meant for supportive material, not as a substitute for discussion. You don’t make it clear if you asking if these things can be done, or are claiming it.
  17. Same experience with military folks working on weapons systems, thinking we had a science budget like they had, when it was about 1% or less
  18. IIRC you were insisting on a certain viewpoint without supporting the position, another behavior that’s frowned upon (as in, soapboxing is against the rules). The bottom line is that staff felt the reports that were filed on your posts were valid.
  19. But not in the exaggerated way you presented it. Astronomers and cosmologists are well aware of the finite value of c, and how it impacts theory and observation.
  20. Seems low to me, too, but not more than an order of magnitude low. You’d probably be living at the site, but you need food and water, and equipment. And it would depend on the duration of the expedition. Even it’s it more, there’s still a huge divide between that and a trip to the moon.
  21. If you’re going to discuss commerce you could at least do some rudimentary cost analysis. “Usually, museums and research institutions spend about $10,000 for big excavations, which covers the cost for scientists to travel to the field and dig up fossils, as well as properly excavate and prepare them” (it helps that you can get volunteers, or even people that pay for the privilege, to work on the digs) https://www.livescience.com/62745-dinosaur-auction-paleontologists-angry.html#:~:text=Usually%2C museums and research institutions,and prepare them%2C Polly said. Even at ten times that, if you can find a million dollars in fossils, it’s quite profitable. Now compare that with the cost of a trip to the moon. And consider whether the market would saturate and drive the value of a moon rock down if the focus was on hailing back moon rocks.
  22. My mistake. You don’t get to derail a thread just because you decide it’s nonsense.
  23. Getting to that elevation is somewhat of a problem, unless you think sherpas can haul everything up. And “significantly thinner” is still significant; it’s about a third of an atmosphere.
  24. There was a recent article documenting how the rate of bigfoot sightings correlates with black bear population. “The results suggest that there's a strong correlation between sightings and the local black bear population—for every 1,000 bears, the frequency of bigfoot sightings goes up by about 4 percent.” https://arstechnica.com/science/2024/01/study-finds-bigfoot-sightings-correlate-with-black-bear-populations/ “It's easy to see how black bears and bigfoot could be mistaken for each other. Despite their name, the bears come in a wide range of colors, from a golden brown through to a deep reddish one, as well as their namesake black. They're also large animals and will frequently stand on their hind legs to get a better view of their surroundings. They also frequent the forested areas that are supposedly bigfoot's favored terrain.”
  25. Does applying the time dilation formula to a radial value less than the Schwarzschild radius have any physical meaning? The imaginary result suggests not
