Brightest gamma-ray burst ever seen, the largest known explosion since Big Bang, has a unique jet structure unlike any other

[Admin]

The gamma-ray burst dubbed "the BOAT," or the brightest of all time, has a unique jet structure that may explain its extreme nature and why its afterglow persisted for so long.

The GRB officially designated GRB 221009A but nicknamed the BOAT, or the brightest of all time, was spotted on October 9, 2023, and stood out from other GRBs due to its extreme nature.

I'll say! So bright, its shine traveled four months backward in time from detection.

I note here from the reference cited.

A structured jet explains the extreme GRB 221009A, https://www.science.org/doi/10.1126...6472541199F70A4C98A6%40AdobeOrg|TS=1686067345

"Abstract Long-duration gamma-ray bursts (GRBs) are powerful cosmic explosions, signaling the death of massive stars. Among them, GRB 221009A is by far the brightest burst ever observed. Because of its enormous energy (Eiso ≈ 10^55 erg) and proximity (z ≈ 0.15), GRB 221009A is an exceptionally rare event that pushes the limits of our theories."

10^55 erg is a lot of energy Consider some of the questions and answers here about the Big Bang

Total energy of the system

I remember reading years ago that the sum total of energy in the universe is (possibly) zero, given matter and antimatter etc cancelling each other out. I guess this could be so given that it apparently started from nothing. At the same time we know energy is conserved. But I guess conservation...
