Would scientists on the other side of blast survive in a bunker? I got an alien using telekinesis abilities to move Moon with the speed of " 1 hour till collide from the moment Moon left the orbit". So how devastating the effect will be?
Also Mars is only twice the diameter of the Moon, and the moon is 1/9 the mass of Mars.
To move from Earth orbit to Mars in 1 hour, you need an average speed at least 73 million kilometers per hour, which is about 7% of the speed of light.
Calculating the pure kinetic energy of the Moon as it smacks into Mars, it comes down to approximately 30 x 1036 Joule (not counting relativistic effects). The Sun outputs 3.6 x 1026 Joule each second. So in that moment of collision, let us say it takes 1 second... this Moon-Mars system outputs the energy of 100 billion Suns.
Since the Earth is approximately the same distance from the Sun as from Mars — even a little bit closer — this means that when the shockwave of energy from this collision reaches Earth... the side of Earth that is facing Mars is instantly roasted to crisps.
Would you at this point chance that someone on a bunker on Mars, at the very epicenter of this 100 billion suns release of energy, will have any chance to survive; in a place where the surface of the Sun is — in comparison — freezing cold?
Short answer: No, not a chance... they will be blasted into elementary particles.
How devastating will the effects be? You obliterate the Moon and Mars into elementary particles... you vaporize half the surface of the Earth in the process... you make ripples on the surfaces of the Sun, Jupiter and Saturn.
