  1. You ca't have acceleration without implied motion can you?
  2. Is there a connection between those two kinds of time dilation? Is it simply that the one cause is the derivative of the other ?
  3. (hope I am not just repeating myself) If the one clock is in freefall(my earlier scenario). ,it does not experience acceleration yet still ticks at a different rate... Is that because the two clocks are still in relative motion? And so the only time they tick at the same rate is when they are both at rest and also experience no (different?) acceleration?
  4. Is there anything special in the (temporal) relationship between a massive body and an object freefalling towards its centre of mass without any lateral motion? I had it in mind that their clocks might tick at the same rate but it seems that they don't. What about if their distance is artificially maintained through acceleration? Do their clocks tick at the same rate for that duration?
  5. Well ,I was wondering whether it was possible to set a ground clock and a distant clock to the same time at a particular instant and thereafter the distant clock approaches the ground clock directly** in freefall. Will the two clocks still show the same time when they meet? ** ie no lateral movement but all movement is along the shortest path.
  6. Suppose we have two reference frames that are not at rest wrt each other (even accelerating). Is there any way at all that a observers in their respective frames can agree upon a mutual time? Is there any way at all for the to synchronize clocks ,if only for the one instant?
  7. Will there be enough generations remaining in our global (human) civilization to put these scenarios to the test? I imagine (without knowledge or research) that your descendants would acquire the characteristics appropriate to their place of living but how many generations it would take,I could only guess at. 10 or 20 ?
  8. I don't follow this part .A typo or two? An autocomplete malfunction ?🤔
  9. Is this at all related to the relationship between two objects one of which goes behind the event horizon of a BH and the other that does not? (I thought I saw that scenario mentioned quite recently somewhere on the forums)
  10. How would you organize the collection of spacetime intervals intervals so as to potentially turn them back into a reality? Would you have a local origin(the start of the first interval) corresponding to the apex of a light cone?
  11. Is there a silver lining to be drawn from the current situation? Are the opponents to concerted action based on scientific understanding who have shown their hands on this occasion broadly the same group we can expect to be digging in their heels when it comes to any action at all when the time comes (of course it has come but seems to be being deliberately ignored-eg the windmills in Texas ploy) Are we getting any closer to a very widespread acceptance that we are all in this together in a very shallow pool or has the populace shown themselves to be ready for more snake oil merchants who will offer them short term satisfactions and attempt to turn us one against another for their own gain? On a practical level are their any parallels between the measures required to fight this pandemic and the mobilization required to address climate change?
  12. Is that the same thing as differentiability?
  13. https://www.bbc.com/news/world-australia-55760673 "Google has threatened to remove its search engine from Australia over the nation's attempt to make the tech giant share royalties with news publishers" Google appears to be flexing its muscle against Australian plans to make laws that will affect its position . Is this tenable? Google is accountable to whom? Its shareholders? Any legal requirements? More generally ,what is the responsibility of multinationals to the countries that they operate in? Do they avoid local laws by resettling ( or making the threat to do so) their assets to more compliant jurisdictions? Are Multinationals now too big to fail? Should they be shackled (or made accountable) so that the power they have cannot be abused?
  14. Rules out Cheney ,then.Vladimir,JCM?
  15. It has yet to be substantiated that he was "really" in J.C.MacSwell's dream. This may be premature speculation but my "Cheney" was the MigL version.
  16. Lest we forget https://twitter.com/i/status/1324078979775684608
  17. Agreed but the point (not so salient perhaps) I was trying to make is that ,for him the blow is softened if he can move to another platform with less followers as his future status (as a leader of a political -to be kind- grouping) will probably still be able to thrive equally well with that reduced amount of publicity The problem with Trump is those who use him for their ends. Hopefully those who oppose him and his loose "political" grouping will be able ,if required to use his presence in a way to further their ends (eg he can be used as an example) Well .it might matter if his term was not about to end as he could put pressure on Twitter to reinstate his account -or make political capital of of his matyrdom and the supposed "assault" on freedom of speech (which of course ,in the large is a real issue .) Everyone is trying to get through and past the next 10 days and so "stopgaps" are not to be sneezed at at the stage.
  18. Is this banning of Trump just a stopgap measure ?(and a response to his incitement to anti democratic insurrection,as well perhaps as a wish to disassociate themselves from further incitements) Won't he find another outlet soon enough? Since he will no longer be President he won't need the amount of followers he has now . The whole question of regulating social media is a huge question in itself. I have always thought that heavy accountable moderation should be compulsory. Other than that the only opinions I have are (obviously) that this is a huge world defining question and that developments are moving ahead at lightning speed.
  19. Well,yes. As to whether that can be achieved I am doubtful ,but I don't claim any expertise to make that judgement. I am hearing that very few Republicans are pressuring him to resign..... And I have heard arguments that impeachment should be used to set a precedent even if chances of success may not be great.
  20. We need to know as much as possible of what went on . If there were conversations between Trump and those who organized this action we need to know this. I am not saying this is necessary to show culpability if enough is already known to show this. But we still need to know as much as possible about this and ,if some kind of a chain of responsibility can be shown then this is to everyone's benefit . We have been told that Trump is like a Mafia boss and never spells things out explicitly but he may have had an off day and shown his hand. And ,if others are revealed in the line of command they may talk for a reduced sentence.
  21. Are they likely to roll up a conspiracy that would actually and directly link Trump or his close advisers to the main actors in this action?
  22. If you record the sequence of radioactive emissions from an atom don't you get a random sequence? Is it impossible or impractical to do that because the time intervals are too small to measure? (hope this makes sense)
