Question:
Light experiences zero time and zero distance so for a photon it must be here and there at the same instance. As the moment a photon is created it must be at position A and B at the same moment.
So for a Photon it takes zero time to reach Earth from the sun.
Why do we then see light taking 8 minutes to reach us?

This is neither correct nor relevant. See the FAQ: https://www.physicsforums.com/showthread.php?t=511170

Because the sun is a distance of c*8min away in our frame.

We experience 8 minutes, not the light.

What do we experience that takes 8 minutes (aside from the fact that it takes 8 minutes for our clock to tick through 8 minutes)?

The time that light takes to go from the sun to the earth, as measured in our frame of reference, of course. (Which is what the ticking clock measures.) How long it takes light to go from the Earth to the sun in any other frame of reference, including that of light, is not relevant.
 

Thread 'A sufficient condition for integrability of equation ##\nabla g=0##'

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...

Thread 'Hawking After 54 Years Confirmed: BH surfaces don't shrink'

Abstract The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence of two black holes with near-equal masses ## m_1=33.6_{-0.8}^{+1.2} M_{⊙} ## and ## m_2=32.2_{-1. 3}^{+0.8} M_{⊙}##, and small spins ##\chi_{1,2}\leq 0.26 ## (90% credibility) and negligible eccentricity ##e⁢\leq 0.03.## Postmerger data excluding the peak region are consistent with the dominant quadrupolar...

Thread 'Relativator (Circular Slide-Rule): Simulated with Desmos - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...
