Calc The Umbrella Academy - The Apocalypse Suite

White Violin causes a bunch of rocks to dislocate from the Moon and fly towards Earth, which Klaus catches.
White Violins frequencies cause large chunks of the Moon to be dislocated and travel to Earth. We're given a value of how heavy the meteor is above (40,000 tons, or 40,000,000kg). It takes less than an hour for the meteorite to reach the Earth. The distance from the Moon to the Earth is 384,400km.

T = 384,400km/60min
= 106777.778/340.29
= Mach 313.784648

KE = (0.5)mv^2
= (0.5) X 40,000,000 X 106777.778^2
= 2.28029877e17 joules
= 54.500448613766728556 megatons


Final Results
Seance stops meteorite (energy) = >54.500 megatons
Seance stops meteorite (speed) = >Mach 313.785

Said meteorite(s) would have killed all humanity (and did so in a bad timeline), so I'm more than pretty sure this would ultimately be even higher (I have a feeling that 40000 tons is just "an impressive sounding number" thrown out there). Plus the sound vibrations that did that to the Moon would be ridiculous.
