Nugatory's latest activity

I don't think there is one, but you can reply saying "posted in error, please don't waste your time replying" and then report your... -
Nugatory replied to the thread I Could there be a non local theory without action at a distance?.I won't presume to speak for the Bohmians, but if I understand properly, non-locality in Bohmian mechanics avoids conflict with...

Nugatory replied to the thread I Could there be a non local theory without action at a distance?.To be consistent with experimental observations that something must (as pointed out by @DrChinese above) travel at superluminal...

Nugatory reacted to SergejMaterov's post in the thread I Would gravitons theoretically act like photons? with
Like.
Gravity’s coupling G is dimensionful, so you only get a meaningful gravitational fine‑structure constant once you specify masses or... -
Nugatory replied to the thread I Freefall and gravity.Proper acceleration is measured with an accelerometer. Imagine a cubical box with six springs inside; one end of each spring is...
-
Nugatory replied to the thread I Freefall and gravity.Objects "experiencing gravity", whether in freefall or not, is not part of the theory of general relativity; it's a misunderstanding...
-
Nugatory replied to the thread I Hydrogen 21 cm line time?.No. I am sorry to say that it is complete nonsense. The Bohr was abandoned long ago because it does not adequately describe electrons...
-
Nugatory replied to the thread I Hydrogen 21 cm line time?.What do you mean by "the hydrogen cloud"? But no matter what you mean by that, it makes no sense to talk about the speed of a bound...
-
Nugatory replied to the thread I Shwartzschild coordinate system.It cannot be done, for about the same reason that we cannot find a transformation between latitude and longitude on the curved surface...
-
Nugatory replied to the thread B Simple mass/scale puzzle.It doesn't. Several posts have already done that: Demystifier's #71, multiple posts from multiple people suggesting that you draw a...
-
Nugatory replied to the thread Vector/Phasor Addition.I'm not seeing what you're trying to do here. What are these ##X_i## quantities and where did they come from in your example?
-
Nugatory reacted to PeterDonis's post in the thread I Does Time-Symmetry Imply Retrocausality? How does the Quantum World Say “Maybe”? with Like.
We already know Nature violates some premise of the Bell proof, because Nature violates the Bell inequalities.
-
Nugatory replied to the thread I Wigner's friend and quantum tunneling.But it can, as long as the wave function has non-zero amplitude outside the box. Two consecutive position measurements will in general...
-
Nugatory replied to the thread B Simple mass/scale puzzle.I agree, but I find that the free body diagram of the two components of the scale (hook attached to the pointer, case) is how to do that.
-
Nugatory replied to the thread I Shape of wave function (probability distribution) of a single photon.It isn't. We explain the double-slit experiment with light by doing a classical calculation of classical electromagnetic waves passing...
