PeroK reacted to Mohdje's post in the thread Undergrad Cosmological Redshift and Expansion with
Sad.
You say that all theories are mathematical in essence, but this is a grave mistake. Mathematics is the most suitable tool for... -
PeroK reacted to Mohdje's post in the thread Undergrad Cosmological Redshift and Expansion with
Skeptical.
سؤالي بسيط للغاية: هل أنت متأكد من أن الكون متناظر حتى تتمكن من طرح هذا السؤال؟ Well, I see many contradictions in your statement... -
Whether the universe has any symmetry at all is irrelevant to the description of frequency shift in terms of four vectors. It's highly...
-
No I'm not. I'm explaining that comoving sources only having cosmological redshift and no kinematic frequency shift is a matter of...

PeroK reacted to Dale's post in the thread Graduate A rotating frame equation for the "carousel experiment" with
Like.
I read the Persson and the Edward’s articles. I liked the Edward’s one. But all they are doing is making an effective gravity which... -
PeroK reacted to Simon F's post in the thread Graduate A rotating frame equation for the "carousel experiment" with Skeptical.
My topic was about presenting an alternative equation without Coriolis and centrifugal terms. I dot not want to spend too much time...

PeroK reacted to haruspex's post in the thread Graduate A rotating frame equation for the "carousel experiment" with
Informative.
https://en.wikipedia.org/wiki/Coriolis_force lays it all out very clearly. Correctly describing the motion in a rotating reference... -
PeroK reacted to Simon F's post in the thread Graduate A rotating frame equation for the "carousel experiment" with Skeptical.
Hello, You can read Persson 2015 in details which is the most documented article recently. Also you can read Edwards and Edwards 2021...

PeroK reacted to nescientist's post in the thread I hope to learn more and realize a grasp of nature's wonders! with Like.
Well, I haven't applied much physics(or even thinking from that framework) since University, and I miss it. So, I'm picking up old books...

PeroK reacted to Mohdje's post in the thread Undergrad Cosmological Redshift and Expansion with Skeptical.
Your point is valid, and I agree with you, but you're explaining a completely different idea. Scientists always rely on Earth as an...
-
But they don't, really. That's my point. Both are due to the different inner products between four vectors, and you can only divide the...

PeroK reacted to Mohdje's post in the thread Undergrad Cosmological Redshift and Expansion with Skeptical.
And I don't know either. All I meant was that Doppler shift and cosmological redshift lead to the same results, but they have different...
-
The ultimate cause is always that the inner product of the light's four momentum with the four velocity of the emitter is different from...

PeroK reacted to PeterDonis's post in the thread Undergrad Cosmological Redshift and Expansion with Like.
It's an attempt to be able to have one's cake and eat it too--to justify using the term "Doppler shift" while at the same time...

PeroK replied to the thread High School Why does continuity still feel weird?.That isn't the idea at all. The idea is that you can use the theorems about sequences that you will already have developed in your...
