Like when our body goes through MRI , current would arbitrarily be produced in different parts of our brain which should cause random movement of limbs and many such effects but it doesn't why?

In stars with enough mass to collapse into a black hole specifically, what causes the "shock wave" that blows apart the rest of the star in a supernova?

As I understand it in stars that collapse into neutron stars, the "shock wave" is created by the rapid collapse of the stars core into a ball of neutrons and then abruptly stopping once neutron degeneracy pressure prevents the core from collapsing any further into a black hole, and leaving behind a neutron star.

In more massive stars, neutron degeneracy pressure is overcome and the core collapses into a black hole, but at what point in this scenario does the shock wave happen and what causes it if there is nothing stopping the collapse?

Is capillary action free energy?

Assuming a substance (example: water in a tree) has risen in height, it now has the potential energy that it didn't have at the bottom of its path.

Do other animals have blood types similar to humans?

Humans have several different blood types A, B, AB, and O. Do other animals have something similar and does it work the same way as humans? Do some animals need a specific type?

Are there known limits to lossless file compression?

Have we hit the known limits for things like text, image, and video lossless compression? Can those be calculated somehow?
