What happens to the number zero on the brink and inside a black hole?

 

Or does a black hole not discriminate information? Or perhaps regarding zero "non-information"?

 

And if zero is not non-information, why is it not?

What happens to the number zero near a black hole is uninteresting. What happens to the mathematician thinking about the number zero as he enters a black hole is.

Nothing. Numbers, as abstracta, are immune to the effects of gravity.

So, thinking of zero is abstract? That means zero does not exist outside thinking minds capable of producing zero.

perhaps then thinking on its self is abstract, but the number zero is "information" any which way you look at it.

All information is lost in a black hole as far as the theorem is concerned.

 

I only asked because everything that goes into a black hole from our perspective is doomed to be "zero". Right? Or not?

Classically what the theorems tell us is that black holes don't care what they eat, the only properties they have are mass, charge and angular momentum. This means that you cannot tell what has fallen into a black hole.

 

In this respect the information about what the black hole has eaten cannot be viewed from outside the horizon.

What if a "black hole"is made to eat a 20MT thermonuclear bomb, which we drop in. When the bomb detonates, what effect will it have?

It's event horizon will get a little bigger as it gets a little more massive - and that's about it.

 

The gravity around a smallish sized black hole is such that a small object falling in would have far more energy than any nuclear device we can produce. If you think of neutron stars - where we could imagine being on a defined surface even if it is untenable in reality - the acceleration due to gravity is around 10^11 times higher than we experience on earth; something dropped from a metre up would hit the floor in a microsecond at millions of metres of per second - a falling mosquito would hit with a greater oomph than a 15inch shell fired from a battleship

But if there are regions in the universe that do not care about numbers, or whatever information, does that not imply that the laws of physics are not the same throughout the universe always?

 

if a black hole is a bath tub drain in our galaxy it means it makes disappear matter and thus energy forever to be lost.

I always thought there was a law that says that all energy is preserved and never gets lost.

You have the classical laws of black hole thermodynamics. The first law is essentially conservation of energy.
