This may be a dumb question, I’m not sure, but I’m asking sincerely.
As I understand it, in each atom, regardless of what kind of atom it is, the nucleus is a certain fixed distance from its electron shell and this does not change. (right?)
So, what if there were matter containing atoms all of whose constituents were closer together? (or farther apart I guess, but I’m asking about closer.)
Is it possible to speculate about the qualities of such matter? Would it be apparent (visible or detectable) to an observer made out of “regular” atoms? (live or machine.) Would it be able to interact with matter made of regular atoms?
Is it possible that what is called “dark matter” could be made up of these more compressed types of atoms?
Just wondering. Thanks!
