So why exactly can't two or more things occupy the same

So why exactly can't two or more things occupy the same space at the same time?

because there's only space for 1 thing

They actually can, there's a possibility that the atoms of two masses can overlap with each other so they have twice a density in one space.

There's about a 1 in 4 million chance this happens when two objects interact with each other.

Science can only answer "How" the universe works, not "Why" the universe works a certain way.

A "Why" question assumes intend, which means there needs to an entity with intentions. If you want "Why" questions answered, ask your local priest, shaman, rabbi or whatever.

>>8247517
Somethings can occupy the same space at the same time as others. Light can occupy the same space as other light. The same goes for other bosons.

I am however a pleb can't answer your questions further.

Because we only perceive the dimension of matter and energy. Energy can possess the same space as you. Other matter cannot, not without becoming you. This is in part because when two atoms get close to one another the electric charges push against each other and prevent them from actually touching one another

If you define that two things are the same when they share the same space simultaneously, then those two things cannot since they would be the same thing.
If you don't, then they can occupy same space and time.
>>
>>8247517
This can happen if there is no time, or in better terms, if a physical absence of time ie possible. In this case a human will exist in every cell of space he's been through in his whole life. And without time, no chemical reaction is possible either. Think about a ghost. Now you have the picture.

go to /philosophy/ pls

>>8247517

this happens because of the electromagnetic property of matter.

I don't have time for a full reply, but the answer is quantum mechanical, and has to do with identical particles, particle exchange, and spin. How all this works together requires examining the symmetries of Lorentz (relativistic) transformations, and is summed up in the spin statistic theorem.

The short of it is, when you consider 2+ particle systems, you have to construct your wavefunction (the thing that fully describes particles in QM) in such a way that it takes into account you can't distinguish between particles of the same kind (say, electrons). Depending on the spin of the particles under consideration, the math tells you either the resulting wavefunction is some combination of the two wavefunctions, or 0 everywhere. Since a |wavefunction|^2 is a probability density, and you have to be able to find a particle SOMEWHERE (area under |w|^2 = 1), the 0 solution cannot exist. The zero solution occurs with spin-1/2-integer particles (fermions), the non-zero function occurs with spin-integer particles (bosons).

So actually, particles (read wavefunctions) can and do occupy the same space at the same time. Wavefunctions are very ghostly in that respect. However, if considering fermions, no two wavefunctions may be identical because you get that 0 solution, so they get a sense of rigidity. This is why all electrons don't "shake down" to the lowest energy state of an atom (know as the Pauli Exclusion Principle), and why >>8247672 is wrong saying it's EM in nature. In contrast, bosons (like photons) CAN occupy the same wavefunction state at the same time. This has the effect of making particles seem farther away from each other for fermions, and closer for bosons.

TL;DR generalized Pauli Exclusion Principle. Read about spin-statistics.

Technically, you can. Just pack the atoms of one thing in between the other item's atoms. There's plenty of space.

Fun fact: The only thing keeping a neutron star from collapsing down to a black hole is this effect. The force associated with it is called the degeneracy pressure. The force is not caused by force carrying particles, but rather the wavefunctions of fermions "excluding" each other.
>>
Holy shit, everyone on this thread is retarded:

The answer is that it depends on what things you're talking about and on what scale you're considering.

Ultimately, as far as we know, things can occupy the same space as other things. This is a black hole.

At various scales there are various forces which prevent things from occupying the same space.

If two things occupied the same space they wouldn't be different things.

Why does not assume intelligent intent. Stop basing all of your logic around anti-theism.
>>
>>8247747
This thread is great what the fuck are you talking about.

But anyways, short and sweet, >>8247735 this guy gets it.

Only fermions, particles with half integer spin, can't occupy the same quantum states as one another. Bosons, particles with integer spin, can totes do that. Bose-Einstein condensation is a manifestation of this fact.

As for what happens to matter in a black hole, we're not actually sure how its distributed, but what that other anon said follows from the fact that the Schwarzchild metric is based on a point-like solution to Einstein's field equations.
