  1. You could take him at his word on his reasoning. He explained how he thought about what an observer on one beam of light would see if looking at another, and how to reconcile the thought with Maxwell’s equations
  2. Excuse me? Tyranny?
  3. A universe from nothing is the opposite position.
  4. Who, and under what context? Can you find a mainstream physics citation that list this as a postulate? A shaky premise, that you are taking as true, instead of conditionally.
  5. Never know? No, not really. SR preceded GR. Expansion of the universe wasn’t involved and there was no evidence of it. We have a timeline of events. Making up an alternate history doesn’t fly.
  6. Yes. The press has been guilty of this as well. Case in point - The impeachment that took place was an example of something that happened behind the scenes, and people latched on to it. Other stuff? Meh. Having said that, Trump’s reshuffling of the Pentagon and not immediately allowing national guard response are things to look at, conspiracy-wise. There are likely things to be found beyond what happened in plain sight. Well, the only way to mess with the voting was to go into the Capitol building, where the votes were being counted.
  7. “may have been inspired by the universal recession velocities” doesn’t fit the timeline “In 1912, Vesto Slipher measured the first Doppler shift of a "spiral nebula" (the obsolete term for spiral galaxies) and soon discovered that almost all such nebulae were receding from Earth. He did not grasp the cosmological implications of this fact, and indeed at the time it was highly controversial whether or not these nebulae were "island universes" outside our Milky Way.” https://en.wikipedia.org/wiki/Hubble's_law
  8. But wholly consistent with Electrodynamics, which is what prompted his investigation, and gave rise to new physics
  9. Eventually, sure. The immediate issue is removing a dangerous man from power. You don’t need to know if there was a hidden conspiracy to commit sedition when he called for sedition in plain sight.
  10. As with the previous responses - if you’re e.g. working two jobs so there’s no free time and voting means waiting in line for 2-3 hours or more, and/or the polling place is a long bus ride away, you’re not going to vote.
  11. Not as far as I know. But if he actively urged them to do it, I would think he’s guilty of sedition itself. He told them to go mess with the vote counting.
  12. Remove the barriers to voting/expand the opportunities (early voting, more locations, mail-in + drop boxes, same-day registration) Pay people to vote if they do it in person - cover a few hours of low-end wages so they can afford to take off work, and make it so employers must give the time off.
  13. He gave a speech right to them, urging them on, after advertising the rally. How much of a link do you need?
  14. The US is not alone in electing a leader who pandered to a base with bigotry and other base emotion, while having an interesting relationship with facts. Trump is perhaps an extreme example. And by the polls, there are plenty of supporters who are comfortable with his foray into sedition and insurrection. Not half of Americans. Less than half of voters; Trump did not get a majority even when he won, and about a third of eligible voters did not vote (edit: in 2020). And we have a voting system with an intrinsic bias, and, as it happens, it’s biased in Trump’s direction.

    As it’s over water, I would imagine this could be automated - pump water up and spray it. Powered by the solar cells. (the semi-snarky response is you wouldn’t pay an American, you’d pay an immigrant, just like with other menial labor)

  17. You have Newton’s gravitation law. You can calculate the size of these other contributions. The acceleration from the sun is about 0.006 m/s^2, but we’re in freefall around it, so we wouldn’t feel anything even if it were larger. The moon has a small effect in changing the net value of g; this was measured back ~1931 by Loomis, comparing pendulum clocks with quartz clocks. Pendulum clocks depend on g, and there was a ~25 hour cycle of variation measured.
  18. When speaking of fractions, in the given context, “smaller” can’t be ruled out as exactly what was meant. It’s moot, though.
  19. I think the problem is that Trump is very much a Republican. For many in the GOP, he only just now crossed the line with sedition and insurrection (and for others, he hasn’t crossed it yet. Elected officials and the GOP base) The senate could have convicted him after he was impeached, but chose not to. The voters could have voted for someone else, or stayed home, but he got even more votes after 4 years of his actions being front and center. He’s been carrying out the GOP’s policies - restrictive immigration if you aren’t white and Christian, tax cuts for the rich, voter suppression, deregulation, no healthcare, abd fully-aligned with Mitch McConnell’s aim to un-do pretty much everything Obama did. No, the notion that Trump is not a Republican doesn’t hold water. To the extent that it appears to be, it’s because certain political views are reprehensible, and the site is biased towards views that reject them. That would give the appearance of this bias. White supremacy would be one example, or political stances that reject treating groups of people equally. The membership is slanted heavily toward those that are interested in science, and it’s not the site’s fault that some political groups reject science that they don’t like.
  20. Salik Imran has been placed on sabbatical (suspension at his request, so as to not distract from his studies) until Mar. 1
  21. That’s one practical way of having the capacity in place. You’d basically be running the system at lower efficiency by bypassing the turbines and condensing steam without extracting work from it.
  22. ! Moderator Note So it’s not evidence that supports your conjecture, to the exclusion of other hypotheses. IOW, it’s not support - it doesn’t show SR to be wrong. So you have no model, and no evidence. You can’t satisfy the requirements of speculations. We’re done. Don’t bring this up again.
  23. Will you be showing us either of the following 1. a derivation of the time dilation equation from QM 2. a way to test your conjecture in a way that is independent of relativity, or present evidence that already exists that fits this criterion I ask because if you don’t, the thread has to be closed as it does not conform to the speculations rules, which requires a model and/or evidence.
  24. ! Moderator Note Nope.Your “new model of the universe” discussion was closed. You don’t get to invoke it here - you used up your chances to support that idea already, and you didn’t.
  25. Not a lot you can do with it, other than delivering it to loads. But in doing so you have to heat up water, which acts as a buffer for variations in demand. If you increase power demand, the first thing that happens is the temperature of the water drops. The reactor fission rate increases as a result, but there’s a lag in the output (it takes time for water to complete a loop through the system) Naval reactors have some design differences compared with commercial ones. Commercial reactors are designed to run at near peak power, without much variation. The much smaller one on a sub is designed to respond the changes in load. (Carrier plants are bigger, so the size-related design constraints are lessened) In some ships/boats. Not “typically” as such. “The Russian, US and British navies rely on direct steam turbine propulsion, while French and Chinese ships use the turbine to generate electricity for propulsion”
