The authors define vacuum as absence of air. AFAIK in physics today there are several other definitions of vacuum.

I hope he'll recover. He really makes math fun and interesting. How can this happen? Did they get hold of his email

This debate reminded me Matt Strassler's recent post that most of the data observed in the accelerators are thrown away [1]: So what’s to be done? There’s only one option: throw most of that data away in the smartest way

"...in any spacetime..." This is just another proof that spacetime as a real entity does not exist. If there are infinitely many spacetimes, spacetime cannot be the fabric of the universe but it can only be fodder for academic car

But physicists already made spacetime redundant by dividing it back to space and time. This was started by Dirac who restated general relativity with Hamilton formalism. The slicing of spacetime was completed in the sixties with ADM formula

I guess you guys found a way to accelerate human body to the speed of light without disintegrating. Why don't you prove your technique first with G-forces?
79.
by nyc111 2y ago
"'Close to the speed of light' means, like, 99% of the speed of light" So, you are saying that it is possible to accelerate human body to 99% of speed of light without transforming the body into a massless particle?

by nyc111 2y ago
"Any massless particle must move at the speed of light" Does not change my argument. Human body is not a massless particle.

"This is the underlying reason why, when you move at speeds that approach the speed of light, you start to experience phenomena such as time dilation and length contraction:" This is not even possible in pulp science fiction. In o

Org mode is great but for taking notes I started using howm https://github.com/kaorahi/howm?tab=readme-ov-file

I use org-mode export to HTML and then ftp that to the server. Is the OP doing the same without the org-mode?

"This video might help. https://youtu.be/UnURElCzGc0?si=MQa2JKT_CMmM-_JL " Sagan's video proves that it's always helpful to investigate abstract concepts with an experiment. But the video also raises an i

I would really appreciate if people writing these types of articles first give rigorous and unique definitions of space and time.

"The third dimension won’t be orthogonal." Are you sure? In a 3-D coordinate system all axes are orthogonal because they make 90 degrees angles with each other. Edit: I see that you mean "cannot be drawn as orthogonal lines

I don't understand what is meant here by "dimension." Is the definition of "dimension" consistent for 3-dimensional figures and n-dimensional figures? In other words, what is the importance of the orthogonality of t
