Using some elementary concepts, I've arrived at the apparent conclusion that all the space seen from a particle moving at the speed of light always collapses to a singularity at distance 0 from the particle itself. Looking for contrary proofs (or errors).


Knowing Lorentz factor is

$$\gamma(v) = \frac{1}{\sqrt{1 - \frac{v^2}{c^2}}}$$

  • $v\quad$ velocity of a moving object in reference to the observer
  • $c\quad$ speed of light

Knowing that the velocity of a photon is always $c$ in every reference system

$$\Rightarrow \gamma(c) = \frac{1}{\sqrt{1 - \frac{c^2}{c^2}}} \rightarrow \infty$$

Using the Lorentz contraction formula

$$\Delta L' = \frac{\Delta L_0}{\gamma}$$

with

  • $\Delta L'$ the distance from the inertila reference frame seen by the moving reference frame

  • $\Delta L_0$ the distance from the moving reference system seen by the inertial reference system

  • $\gamma$ the Lorentz factor

$\Delta L' \rightarrow 0$ always

All the space$^*$ collapses to a singularity point overlying the reference frame moving at speed of light.

$^*$seen by the very reference frame moving at $c$

The computation is valid for an inertial reference system put in any point in space, for that I used the generalization "all space".

Is Does the whole universe collapsedspace collapse to a singularity, for a photon?
