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)?
