Don't most of the computation as to the total energy of the event assume the event radiates equally in all directions?
Isn't the amount of energy drastically smaller if it's a focused beam?
Why do we assume spherical and not, for example, a directed attempt to communicate, the back end of a starship drive pointed at us, or just a natural phenomenon the is unidirectional.
- EamonnMR 4y agoThe chances of a focused beam tagging us are astronomically small.

- _tom_ 4y agoAnd that's assuming it is random. I still want it to be aliens trying to reach us about our extended warrantee!
- kisper 4y agoThe wikipedia article seems to suggests that gamma ray bursts are actually believed to occur in beams of 5-20 degrees in width. https://en.wikipedia.org/wiki/Gamma-ray_burst#Energetics_and_beaming https://en.wikipedia.org/wiki/Gamma-ray_burst#Energetics_and...
