- That's the floor, or rather the atomic bonds in the floor and in the ground below.
- Well, looks like it somehow got transmuted on the atomic level into oxygen.
- They'd radiate, lose energy, and plunge into the atomic nucleus.
- OK, that is about the same magnitude as the width of an atomic nucleus.
- So today we are building molecular machines versus atomic machines.
- These are the atomic bonds and the molecular bonds that create solid objects.
- Because neutron stars are super dense objects, they are like giant atomic nucleuses.
- This forces electrons into the atomic nuclei, where they turn protons into neutrons.
- So the dark matter fluctuations tend to attract more dark matter and the atomic matter follows that.

Etymology
The word atomic comes from the Greek atomos, which means 'not cut' or 'indivisible' and comes from a- 'not' and tomos 'cut'. Because early scientists thought atoms were the smallest uncut pieces of matter, atomic now means 'relating to atoms'.
