  1. Will making the walls taller do anything in my problem? Please explain how that makes any difference.
  2. ! Moderator Note "Your experience" doesn't really matter; it needs to be mainstream science if you're going to cite it in support of anything. Also, you posted this in philosophy, so you are expected to discuss philosophy. If you have a model of consciousness that you are willing to defend, post it in speculations.
  3. Beware papers that reference the author a lot, and especially if one of the references is on the Alcubierre Warp Drive. Sonny White has a history of making fanciful claims. This isn't based on mainstream physics. Moved to speculations.
  4. "Add more mercury" is a new item The OP had a fixed amount. There is no more mercury to add. It sinks less than a foot because the weight of the rock is less than the mercury it displaces. So if the rock is heavier, this is not the case. So you are giving a specific case where this works, and my objection is that there are conditions where it won't, specifically the scenario where "it would be theoretically possible to RAISE a rock, in a tight fitting container, with less than it's own weight of mercury, using the head of mercury to exert the required hydraulic pressure on the base of the rock" the problem being that this won't work under the parameters of the OP, since a tight fitting container is not the described scenario, and as such, you would violate Archimedes principle. As I stated. IOW, your counterexample is not one to which I was voicing an objection. Yeah, my bad on this in a previous post - I googled it and saw a different number. Doesn't change the overall issue, though, just the numbers. Let's say I have a 100cm tall pole with a 1 cm^2 cross section and I put it (long side up) in water, 1 cm deep. The mass of the water is, at most, 1 gram. The mass of the wood is, say 50 grams. You are assuring me it will float. Why does Archimedes principle fail in this case? If your assertion were true, ships/boats would never run aground.
  5. How else do you get it to look like gravity, which has monopoles?
  6. So where is this pump, in the OP? How do you lift the rock? All there is is the static pressure, as far as I can tell. And if it’s not that deep? Just tried it. Unsurprisingly it didn’t work. The wood bottomed out. Why do you think the wood would displace less than its mass?
  7. Except that in hydraulics you exert a force via a source of external pressure which is lacking here, so it's really not.
  8. If you had a rock on top of a fluid and there was no place for the fluid to go, then the rock would not sink. But that does not "lift" the rock. But you already said (I only quoted part of your post) you have a gap, so no, this does not work. But, again, your scenario (and the one in the OP) is not a tight-fitting container.
  9. That violates Archimedes principle: an object will displace its own weight of the fluid. If it is less dense it will float, BUT there needs to be enough of the fluid present for this to happen. Otherwise it will bottom out. So 500 kg of mercury (a little less than 100L) will not float anything over 500 kg. exchemist notes this above.
  10. That sounds like word salad. Explain what "limit momentum" is and show me where you used that phrase in this thread. Just posting this is insufficient. You need to make the connection between what you post and what you are responding to. You are rapidly using up any goodwill that this is a good faith discussion, and that this isn't just spamming nonsense.
  11. “what causes the "Curved Fabric of Space" return to its previous state, into its unbent position?” is pretty clearly a question, albeit based on a physically unrealistic scenario
  12. They had already appeared before the committee. It’s doubtful they would have let her testify if it wasn’t corroborated. The republican responses have not been under oath, and sometimes, like this, unattributed. Take them with a huge grain of salt. Pay attention only if they, too, testify under penalty of perjury
  13. ! Moderator Note If you were Spike Milligan offering his insight, it might mean something. ! Moderator Note Yes, exactly. It’s off-topic in a thread about depression, because as you have just admitted, it’s not about depression.
  14. ! Moderator Note Can we get back to the topic of the OP? Telling someone to smile, or to relax, is not dealing with depression
  15. I just did a search, and “neutral” only appeared in this post. So how could you have explained it before?
  16. They are indeed equivalent mathematically, which is why you can't say one has to be taken as true and the others as false. Meaning that the view that the cat is in a superposition of states and the wave function collapses is a valid way of looking at the problem. So that leads me to think that your view is not actually what the many-worlds interpretation actually says.
  17. Do you have a credible source for this?
  18. Many worlds is an interpretation of QM rather than being QM theory, but if you think the cat is in one state but we just don't know about it, that sounds like a hidden variable theory, and that runs afoul of Bell inequality experiments.
  19. No. The neutrinos are oscillating between mass eigenstates, but if there were internal structure there would have to be component particles. There's no evidence of this.
  20. What? Information is negative, somehow?
  21. No. Fundamental/elementary massive particles show no evidence of having any internal structure. Electron, muon, tau, and the associated neutrinos, all the quarks.
  22. At one time, yes. But then it was discovered that neutrinos oscillate between the different “flavors” which requires they have mass. The upper limit (measured in energy) is less than 1 eV
  23. Smallest object with mass or object with the smallest mass? Elementary particles are pointlike. Smallest nonzero mass? Probably the neutrino, when considering all flavors with the oscillations.
  24. ! Moderator Note As opposed to other times, where nobody encouraged people to conform? You need to re-form this so that 1. it's not an exercise in begging the question (i.e. establish that you have a valid premise) and 2. It's posted in the proper area of the forums. This is not a discussion for The Lounge.
  25. ! Moderator Note The discussion should take place here.
