I don't think you understand how big 1.9 billion Castle Bravo's is. That number is exceedingly exaggerated to absolutely insane levels.
BS on this.
Quoting: Anonymous Coward 29348827 30 miles diameter comet @ 1000kg/m^3 density @ 56 km/s impact velocity = 9.24 x 1025 Joules released = 2.21 x 1010 MegaTons TNT = 22,100,000,000 Megatons of TNT equiv energyor, the energy equiv of 1.9 billion Castle Bravo explosions (15 Mt) watch in 1080HD and full screen with sound on: [ link to www.youtube.com] Imagining 1.9 billion times that power in an impact event takes a lot of good imagination. sorry, that should be ' = 2.21 x 10^10 MegaTons TNT 'Wow I am sleepy this morning! corrections: 30 miles diameter comet @ 1000kg/m^3 density @ 56 km/s impact velocity = 9.24 x 10^25 Joules released = 2.21 x 10^10 MegaTons TNT = 22,100,000,000 Megatons of TNT equiv energyand would be the equiv of about 1.5 billion Castle bravo explosions... I calculated the above using the parameters listed above. The 1.3 billion Castle Bravos number used earlier came from the 20 billion megaton total earlier calculated by others that I used. Its all guesses and will vary some depending on the actual size and density, but it all says in the same ballpark. Even if we go very conservative and put this at 20 miles diameter(instead of 30) and reduce the density to 600 kg/m3(instead of 1,000), we still get = 1.64 x 10^25 Joules = 3.92 x 10^9 Megatons TNT = 3,920,000,000 Megatons of TNT [ link to impact.ese.ic.ac.uk] So a very conservative estimate would put it at about 4 billion Megatons of TNT, or 266 million times the energy of the Castle Bravo explosion shown here.
