What can be the effects over the path itself of a gamma-ray burst traveling between two intermediate points of space-time?

Question

We assume that a gamma-ray burst travels from a source $S$ to a target $T$, and we consider how our gamma ray interacts with our path, when our ray travels between two intermediate points (in space-time), two points thus between those $S$ and $T$, say us $A$ and $B$. I am interested to know what the effects are, if there are any, of a gamma-ray burst travelling in transit from our intermediate points $A$ and $B$ over our path of void (empty set) itself.

My belief is that an appearance of such energy, in transit from $A$ to $B$, has a consequence on the cells of space-time. Is it falsifiable, or what can you say about that a gamma-ray burst travelling from intermediate points $A$ to $B$ should interact with the way (where are defined certain fields or maybe that I've called cells of space time)?

Answer 1

The validated model of cosmological data depends on General Relativity. In GR space time is continuous, no "cells".

In this model bundles of energy , as these hypothetical gamma ray burst can be described, will distort space time at their trajectory , so molecules as the gammas are passing with velocity c, will feel a gravitational pull. If the gammas fall on some masses, depending on sizes and energies they will melt them or turn them to gass, or if it is a star or a large planet, they will be absorbed , as happens when they are detected here on earth.

(One must also take into account the redshift due to the expansion of space from their creation to our present space time-moment.)
