An answer may come from the attempts the people are making to try to develop a theory of quantum gravity because under one of the models for this called up loop quantum gravity spacetime itself almost consists of, like, you can think of it is like a little a atom of spacetime; and one possibility is that when you start to cram everything very close together when space itself is packed down into a small enough point that it can't keep shrinking it, it can't keep compacting it.

Prime numbers — the numbers that can't be split up into smaller factors and are thus the atoms of arithmetic — have an almost holy status today.

If the amount is smaller than expected based on the number of positronium atoms that entered the chamber, then some of it may be turning into mirror matter.

Two and a half millennia ago, the ancient Greek philosopher Democritus imagined slicing bread into ever - smaller pieces, down to irreducible specks, and the concept of the atom was born.

Fusion is the opposite of fission, which frees energy when an atom like uranium splits into two smaller atomic nuclei.
