Yes, indeed What I mean is that mathematics is meaningless without physics. I must clarify an important point: I am not fluent in English and I use a translator, and this translator included in the keyboard sometimes makes mistakes.

You say that all theories are mathematical in essence, but this is a grave mistake. Mathematics is the most suitable tool for understanding physics and physical phenomena. Mathematics is meaningless without physics . If you were to create an equation that calculates different numbers simply by...

سؤالي بسيط للغاية: هل أنت متأكد من أن الكون متناظر حتى تتمكن من طرح هذا السؤال؟ Well, I see many contradictions in your statement. First, you say that we live in a FLRRW space, which is the space that most strongly dictates homogeneity, congruence, and symmetry. Second, I didn't assume...

My question is very simple: are you sure the universe is symmetrical to even pose this question? I agree with everything you said except for one point: that the universe is symmetrical.

Your point is valid, and I agree with you, but you're explaining a completely different idea. Scientists always rely on Earth as an observer, but you're explaining the idea of observer independence, meaning every celestial body can be considered an observer. This is difficult to implement with...

Didn't you say it was a personal definition? If so, you must have proof of its validity.

If it's a personal definition, do you have any proof of it?

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 mechanisms. The first works on the motion between the observer and the observed, while the second works on the wavelength of light in spacetime. They are both...

ويرجع ذلك إلى اختلاف المصطلحات. Ultimately, there is no single cause for the shift; it may be related to movement between the observer and the observed, and sometimes the shift effect may result from side effects such as the expansion of the universe, the redshifting of light wavelengths, and...

You raise an excellent point. I would add that while cosmic expansion is the standard interpretation of the redshift, this does not rule out additional contributing mechanisms. Attributing the entire redshift to expansion alone may be an incomplete explanation of the phenomenon.
