After blowing up the Moon, making it lose more than half of its mass, what did
Koro-sensei do to prevent it from crashing onto the Earth? Given the loss of
mass, the Moon would have lost the centrifugal force that kept it from
crashing onto the Earth. So, there must be something that he done to prevent
it, because if not, the World Leaders would've noticed and said something
about the Moon getting closer.

How did Koro-sensei prevent the Moon from falling onto the Earth?


Physically speaking, assuming there weren't any debris from the moon blowing
up and hitting the earth, there's no real reason for the moon to fall down.

Gravity is determined by (among other things), the product of the Earth's and
the Moon's masses. The acceleration is determined by the force of gravity
divided by the moon's mass, so if you do the math, the only thing that matters
in this problem space is the Earth's mass. The moon has no say in it.

It's similar to the reason all objects fall at the same acceleration on Earth,
regardless of mass/weight.
