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...
-
Dale replied to the thread I Why measure the speed of light in one direction?.In general, you like to try to validate your theories against experiment. However, in this case the one way speed of light is a...
-
It is worth noting that in some specific cases the two family of "slanted" grid lines drawn in the diagram may result as orthogonal...
-
Dale reacted to pervect's post in the thread I Confused about time dilation -- motion vs energy with Like.
As others have pointed out, it's a bit more complicated than that. I'm guessing that you are assuming there is some state of "absolute...

Dale reacted to Choppy's post in the thread What should I do if I found a paper with same result as mine? with Like.
Unfortunately one of the challenges with research is that when you're working on a problem, particularly when it's a problem of...
