At light speed, Einstein’s equations break down and nothing makes sense
---
The relationship of light to time is nonintuitive. Mathematical limits allow us to figure out
what happens to photons at the exact speed of light where Einstein’s equations break down.
At the speed of light, clocks stop — and the Universe is shrunk to zero size.

What do Einstein’s equations tell us?
. . . , let’s use the approach of limits . . .
. . . . what will happen when you get to the forbidden value.
. . . No time, no space

At light speed, Einstein's equations break down and nothing makes sense

Using Einstein's equations and particle accelerators, we can figure out what time looks like from the perspective of a photon.

At a constant speed of light (c=1), all physical limits are violated.
The quantum of light (h) enters in the continuum of neither time nor space (nor gravity-space).
The quantum of light (h) enters in the absolute Minkowski 4D spacetime (without gravity).
To get back, is needed to use the "method of renormalization" or
"The law of conservation and transformation of energy/mass".
