How likely is a gamma ray burst
Web21 okt. 2024 · The energy in gamma-ray bursts is almost incomprehensible: In a few seconds they can emit as much energy as the sun will over its entire 12-billion-year life span. Their power comes from their... WebCould the Earth survive a gamma ray burst if that burst occurred in our galaxy and the Earth is in the Sun's shadow? The main factors of that question are: if the Sun is massive enough to block it and if the burst is of short enough duration that the Earth will be in the Sun's shadow long enough.
