> Does The Singularity Exist?
Only physical objects exist.
For example: Black Holes, Stars, planets and muons.
(Humans in an airplane are considered as part of one object)
Physical objects always have a size.
Points, objects which have no size, physical don't exist.
The same with singularities.
The physical world, i.e. the movements of the stars and planets, can be
described by mathematical laws i.e Newton's law.
When we do that (to make things simple) we consider all the objects
studied as a point with a finite mass.
(Or the all the mass is concentrated at one point)
Newton's Law is described as F = m1*m2/d^2
This is no problem, in a simulation, aslong as the distance d between the
planets, is large compared to r=r1+r2.
With r1 being the radius of m1 and r2 the radius of m2.
When d is equal r1+r2 or smaller, the two objects collide and both masses
have to be replaced by a new object with a mass m1+m2.
When you implement these constraints in a simulation, the distance d never
becomes zero and the singularity issue (dividing by zero) is prevented.
The collapse of a star is a physical process and the laws that describe
this collapse should match of what is observed.
If the collapse has a finite duration and the result is an object with
a smaller size and a higher density, than the laws (mathematics) which
describe this, should show the same results (in a simulation).
When the result is an explosion than the (laws) simulation also should
end in an explosion.
Hopes this helps.
