Introduction[]
In Steven Universe, a Gem Spaceship was going to make a blast this huge, but it was interrupted. I'll be calculating the attack power of this Gem Spaceship.
Calculation[]
Earth diameter = 12742 km
Explosion diameter = 1639.49 km
Explosion radius = 819.745 km or 819745 m
W = R^3*((27136*P+8649)^(1/2)/13568-93/13568)^2/1000
W is yield in kilotons of tnt, R is radius in meters, and P is pressure of the shockwave in bars, the standard overpressure is 20 psi or 1.37895 bars.
W = 819745^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2/1000 = 44271256110.62 Kilotons of TNT
Final Tally[]
Gem Spaceship's Attack Potency = 44.27 Teratons of TNT (Country level)
