Dale replied to the thread I How strong is the justification for low probability extreme thermal fluctuations?.> the probability of this is also the same value P. > > Is the experimental evidence that we have for establishing these probabilities... -
Dale replied to the thread B Is a table levitating possible, even at a minuscule probability?.I think this is a poor question. It is not well defined. What counts as levitating? How far off the ground? How long? Are we allowed to...

Dale replied to the thread B Is a table levitating possible, even at a minuscule probability?.There is a certain level of probability which is so close to 0 that if you did observe it then you would think that your theory was...

Dale replied to the thread B Is a table levitating possible, even at a minuscule probability?.Or if you like the “nothing ever touches” thing then you can say that every table levitates all the time.

Like.
Me again. Just felt like writing again to appreciate your patience, and to kind of explain where I was coming from after you've helped... -
Dale reacted to ojitojuntos's post in the thread Help me understand why “Block Universe” is not scientifically proven with Like.
You are correct. While my questions were mostly philosophical, it was very enriching for me to read you and others who engaged with me...

Dale reacted to Herman Trivilino's post in the thread Help me understand why “Block Universe” is not scientifically proven with Like.
Theory and experiment are both essential to physics. In physics, math is a tool. The block universe is an interpretation that's...

Dale replied to the thread Help me understand why “Block Universe” is not scientifically proven.The debates about probabilities in QM are far stronger than the debates about the block universe. However, I think that you miss the...

Dale reacted to PeroK's post in the thread Help me understand why “Block Universe” is not scientifically proven with Like.
Let's take non-determinism to mean that two identical experiments can have different outcomes. The universe as a whole is essentially a...

Hey all. Looks like my 15 year anniversary of joining PF happened yesterday (while my internet was down). Just wanted to say thanks to...

Dale reacted to James Hasty's post in the thread I Why measure the speed of light in one direction? with Like.
My viewpoint is that for all inertial observers with Minkowski coordinates, Maxwell's equations posit the speed of light to be...

Dale reacted to pervect's post in the thread I Symmetry of motion in the special theory of relativity with Like.
So far, so good. You have described the symmetry principle of relativity well. And it is indeed puzzling how this is possible - at...

Dale reacted to Sagittarius A-Star's post in the thread I Why measure the speed of light in one direction? with Like.
You could write Maxwell's equations in the following primed coordinates (given any inertial coordinate system x,y,z,t). $$x' = x \ \ \ \...

Dale reacted to Nugatory's post in the thread B What qualities does time have other than linearity, motion, and speed? with Like.
There's no sensible answer to your question until you have defined what you mean by the word "time". This being a physics forum where we...

Dale reacted to fresh_42's post in the thread I Hawking After 54 Years Confirmed: BH surfaces don't shrink with Like.
Abstract The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise...
