I don't know if there is enough knowledge acquired yet about Bose-Einstein condensates to answer my question, but here it goes....

From what I have read about the subject, I understand that the atoms in such a condensate appear to occupy the same space.

If this is so, is there a limit to the number of atoms that can occupy that same space?
How would this affect the actual matter density of the element in question?

My understanding of this, and others may correct me if I am wrong, is:

a) there is no theoretical limit that is known as to how many atoms (or other bosons) may condense into a Bose-Einstein condensate.

b) that they occupy the same space is not the same as saying they occupy the space that would be otherwise occupied by a single atom - on the contrary, my understanding is that each atom (or other bosons that is condensed - it does not only apply to atoms) will spread out to occupy the space also occupied by the other bosons, so there is no increase in density, only a smearing of the boundaries between one boson and its neighbours.

Neutron stars can be considered as similar to a Bose-Einstein condensate where the density reaches about 10^14 grams/cm^3 before they collapse into a singularity

Neutron stars are cool.

Neutron stars are cool.

Not if you happen to be standing on one at the time []

[Mjhavok]

True.

I literally laughed out loud at that reply!  []

Neutron stars are cool.

They are actually immensely hot between 500 000°C and 1000 000 000°C...

They are quite small so don't have much area to loose heat over, and made in supernovae.
