Does The Singularity Exist?

Singularity is a point in spacetime where incredible amount of matter is
compressed into a tiny space of zero size and infinite density. But,
the question is, ” Does it exist?”

Singularity is not a physical object, it is a mathematical entity. It
arises when the denominator is zero. We all know we cannot divide by
zero, so that’s a problem and mathematicians call that value
singularity. If a singularity popes up in an equation, it means that the equation has been to make predictions in areas where it doesn’t cover
like using Newton’s Gravitational Equation to describe a black hole.

General Relativity fails at the quantum scale and needs to be replaced
by Quantum Theory of Gravity which we don’t have.

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.
