Any massless object will travel at the speed of light. That’s the default speed of the universe. Gravity can’t stop you anymore and time stops permanently.

But the following questions arise: - how do photons decide their direction of travel? - From a photon’s perspective, what is the relative speed of other objects? Since time isn’t moving, all objects must appear stationary - Why is there a default speed of travel in the universe?

Basically, the photon reaches its destination the very moment it was emitted at its destination, from the Photon’s perspective

And many more questions.
