but black holes are still stronger.
a coin sized black hole would've already weighed more than the earth and could easily decimate it, so gamma ray bursts are strong as hell, but not threatening the whole galaxy
How interesting! And, did you mean that a coin size black hole has more gravity than the earth? How many coin sized black hole do you thin are out there?
GAMMA RAYS ARE REALLY DANGEROUS; THEY'RE THE SHORTEST WAVELENGTH OF RADIATION AND COME FROM EXTREMELY HOT OBJECTS LIKE NEUTRON STARS, SUPERNOVAE, AND CERTAIN PLACES CLOSE TO A BLACK HOLE. SOMETIMES, THERE ARE GAMMA RAY BURSTS WHICH CHANNEL MORE POWER IN 10 SECONDS THAN OUR SUN IN IT'S ENTIRE 10 BILLION YEAR LONG LIFETIME. IF A GAMMA RAY BURST WAS SHOT AT EARTH IT COULD DESTROY THE ENTIRE SOLAR SYSTEM TOO. THEY DON'T EXPLODE LIKE A BOMB, BUT THEY INSTEAD SHOOT OUT TO BEAMS, SO IF ONE IS SHOT IN THE EARTH, WE'RE COOKED.
