  1. So if I have a charged particle on my desk emitting a photon due to constraint against gravity alone, that I can detect with my photon detector with the detector in free fall, there will be no detection whatsoever if it's not in freefall? Or no detection only if the detector is comoving and similarly constrained against gravity? Or I guess detectable or not in other frames dependant on how there movement is with regard to the Rindler horizon? (Does the wavelength of the photon approach infinite with respect to a frame coincident (somehow?) with the Rindler horizon?
  2. Thanks Marcus I'll check out Rindler horizon and see if I can make sense of it.
  3. LOL, yesterday and the days before, notwithstanding...but you have me there.
  4. I would hope not, but this is going to be much closer than it should be...which will still be true if the Dems win in a landslide...but can we really take anything for granted? Trump may or may not be more likely to win than in 2016 or 2020, but IMO he's considerably more dangerous.
  5. If it's radiating in any frame it should be radiating in every frame. Since it is being accelerated in it's instantaneos inertial frame should it not radiate? Same event should take place in each frame, even if seen differently, correct? What am I missing? Other than inside neutral atoms, shouldn't any charged particle constrained in a gravitational field (so not in free fall) radiate, even if negligibly/undetectably? Special conditions (that I don't understand) aside: "According to the Larmor formula in classical electromagnetism, a single point charge under acceleration will emit electromagnetic radiation. In some classical electron models a dmitistribution of charges can however be accelerated so that no radiation is emittedhttps://en.wikipedia.org/wiki/Nonradiation_condition#:~:text=According to the Larmor formula,that no radiation is emitted." https://en.wikipedia.org/wiki/Nonradiation_condition#cite_note-Pearle_1978-1
  6. Not sure the voters would appreciate the bait and switch, especially to Harris. (Though I think there is currently a move to recover her popularity which is much needed to run on the ticket as VP)
  7. Did INow get to it with his orange crayons?
  8. Definitely a good idea to clean them once you're happy again...
  9. Fun fact: Jimmy Carter has lived post presidency more than 10 years longer than any other president ever has. (43 years and counting...plenty of time for his successors to make any adjustments to changing circumstances)
  10. I don't think the fallout, if there will be any, from Putin doing in Navalny would have registered on any polls yet.
  11. I would like to think that Trump's base is not as committed as he would hope (and given it's Tump you can read that as "he should expect"). They can't be all of one mind. Even the rightmost news medias seem to be holding Putin for his treatment if not directly ordered assassination of Navalny. Trump has not yet commented, and has been a longtime admirer if not mutual supporter of Putin. Haley is calling his silence out. Accurately. If she doesn't get at least a temporary bump in the polls at Trump's expense Trump will likely win in November if Biden struggles or if their is any significant drop in the economy even beyond his control. Mostly my opinion of course. Maybe tomorrow I'll feel a little more optimistic. Hopefully I won't have to and I'll see that bump. Also just noticed Stringy's post...hopefully that has an effect as well.
  12. I don't know for certain but the statement and graph didn't seem to be in support of climate denial...quite the opposite, though I really should have directed my post more at Bufofrog. Hopefully thidmir will clarify.
  13. According to Lee Zeldin this could happen in the US as well: "Former New York Republican Representative Lee Zeldin compared the death of Alexei Navalny to former President Donald Trump, saying that Democrats want to make sure the former president "dies in prison." "As the world reflects on the murder of Alexei Navalny at the hands of [Russian President Vladimir] Putin, it's worth remembering that Democrats are actively doing Biden's bidding as they also try to imprison his chief political opponent, Donald Trump, remove him from the ballot, and ensure he dies in prison," Zeldin wrote in a post on X, formerly Twitter." https://www.newsweek.com/republican-compares-trump-navalny-democrats-want-him-die-prison-1870722 I think there is a slight difference between the two cases but I can't quite put my finger on it... Though some Republicans like Nikki Haley don't seem to share Zeldin's view of poor Donald: https://www.politico.com/news/2024/02/16/navalny-death-trump-putin-00141899
  14. Russia has been killing people for hundreds of years though...so we don't need another Tucker Carlson interview to understand why this should be okay.
  15. Be nice! It's still a heavenly body...
  16. It's either one of the big Ms, usually the lesser one, depending on which of them's acceleration is of interest.
  17. Might be part of the equation though...along with distance and the fact that despite there being no preferred frame in physics...the cmbr represents a pretty substantial headwind if you want to get anywhere on those scales fast. With regard to finding new places to thrive, we might want to think about taking better care of our planet before we plan it.
  18. Many small businesses do essentially that, though usually taking on more overhead and risk. I share many of your concerns with larger corporations, though I think they are useful and potentially can be more so, especially if we can... ...accomplish this, and thereby properly regulate corporations such that what is incentivised is more in line with the Public good.
  19. When you started your career path was that your primary goal, to make as much money as you possibly could? I suspect it wasn't, though I also suspect you preferred to be adequately compensated for your efforts, well above that of the average human on this planet. The fact that you could be successful in doing that has much to do with the fact that you live in a (far from perfect and really does need to be regulated and improved) capitalist economy. Don't throw the baby out with the bathwater... Though by all means change the bathwater and remember to wash the baby...even if the lobbyists claim the water smells great... And don't fall for the "New improved Bathwater...now with Hydroxychloroquine!"
