gen x replied to the thread High School Einstein equations don't work at large scale?.Time will show the truth The truth is out there -
gen x replied to the thread High School Einstein equations don't work at large scale?.Does massive gravity, theory where graviton have mass produce correct results?

gen x replied to the thread Undergrad Was Richard Feynman's explanation of the twin paradox wrong?.I wrote 100+ years

gen x replied to the thread Undergrad Was Richard Feynman's explanation of the twin paradox wrong?.I am not learning, I just listen from time to time about this theories. Learning mean do physics=do calculation. As I already said, I...

gen x replied to the thread High School Einstein equations don't work at large scale?.Ok than just tweak MOND that works at all scales. Is it possible that gravity Gm1xm2/r^2 works differently on large scales? If yes where...
-
gen x replied to the thread High School Einstein equations don't work at large scale?.How we know that we measure mass of these stars,planets in this galaxies correctly? maybe our method for measure mass is wrong...
-
gen x replied to the thread High School Einstein equations don't work at large scale?.Can you explain why we need to modify Newton dynamics, didn't we already said that Newton physics is wrong and we must use GR for...

gen x replied to the thread Undergrad Was Richard Feynman's explanation of the twin paradox wrong?.if it is just click bait then no need to further explanation. I learn from this forum Einstein and Newton was wrong in so many things...
-
gen x replied to the thread Undergrad Was Richard Feynman's explanation of the twin paradox wrong?.I didnt understand well, so where was Feynman wrong?
-
gen x posted the thread Undergrad Was Richard Feynman's explanation of the twin paradox wrong? in Special and General Relativity.Here Tim Maudlin explain that acceleration is not reason why one twin become younger, and that Feynman explained that wrongly? Is this...

gen x replied to the thread Undergrad Newton's bucket experiment.Why Newton didn't conclude, now water rotate in relation for example Earth frame? I think he wrote, that water rotate in relation to...
-
gen x replied to the thread Undergrad Newton's bucket experiment.And what is your conclusion? If we don't have matter in universe, does we have only one possible frame?

gen x reacted to Roberto Pavani's post in the thread Undergrad Newton's bucket experiment with
Like.
The Riemann tensor of the spinning bucket is a coordinate-invariant fact, sourced by the bucket+water's own ##T_{\mu\nu}## (the angular... -
Mirror the system. Tie the handles of two similar buckets of liquid together with a string. When the combination is spinning in space...
-
gen x replied to the thread Undergrad Newton's bucket experiment.My evidence is pure logic, because of inertia water/bucket will continue to spin. Isn't that so trivial? It is not possible to remove...
