What is the minimum amount of space that mass can fit into?

acording to einstein,objects are not in space,but are spatally extended.
Physical objects are not in space, but these objects are spatially extended (as fields). In this way the concept 'empty space' loses its meaning. ... The field thus becomes an irreducible element of physical description, irreducible in the same sense as the concept of matter (particles) in the theory of Newton. ... The physical reality of space is represented by a field whose components are continuous functions of four independent variables - the co-ordinates of space and time. Since the theory of general relativity implies the representation of physical reality by a continuous field, the concept of particles or material points cannot play a fundamental part, nor can the concept of motion. The particle can only appear as a limited region in space in which the field strength or the energy density are particularly high. (Albert Einstein, Metaphysics of Relativity, 1950)

But then I also heard that the minimum space that mass can fit in is defined by its event horizon.

More mass can not fit in that space ... OR else the EH would expand. Therefore a bit of information can be represented as an area on the surface of a Black hole.

maybe plancks distance=1.616x10 to -33 cm.?i beleive this is the smalleswt distance between 2 objects according to the mainstream.

And I think only a planck mass can fit in the planck distance^2 ... this is my understanding of a bit of energy ...

nassim haremin explains this.i didnt do the math so i dont know if he is right,but according to him if you took all the stars in the known universe and put them in a cubic centimeter of space[assuming you could squash it that much] using this distance between them,you would fall way short of filling it up.you wind up needing something like 10 to the 94 power to fill the space.if interested check him out on youtube.his 6th vidoe explains this.

The question is not answerable. The singularity in a BH in theory can consume any amount of matter, so matter/mass can be squeezed arbitrarily according to classical GR.

However, the theory of space-time breaks downs near the Planck mass. So it is not known whether matter actually becomes arbitrarily dense near a singularity.

Don't mistake density for volume. The circumfrence of a Neutron Star is about the same as the distance from one end of Manhattan to the other but the neutron star is usually between 1.3 - 2.1 solar masses (Our Sun is = to 1 solar mass).

A black hole has infinite density, the actual "core" of a black hole is extremely small.

i am going to assume that you are refering to dimension, or "space" as outlined by the 4 we are used to. L,W,H,T
i would imagine the Higgs Boson (if it exists) would be the smallest area that would have any mass wether measurable or not.
