I'm thrilled by the dimention factor of viruses. Check this:
If you divide 1 meter in a thousand parts you have a millimeter (0.0393701 in).
Now, if you divide 1 millimeter in ONE MILLON PARTS, you have a nanometer (1 nm = 3.937E-8 in).
The Corona 19 virus measures about 120 nm and it's not even the smallest virus out there that may extinguish the human species. By comparison, an atom measures about 0.1 to 0.5 nm. Amazing. Also, believe it or not, let me quote:
In terms of their absolute numbers, viruses appear to be the most abundant biological entities on planet Earth. The best current estimate is that there are a whopping 1031 virus particles in the biosphere. We can begin to come to terms with these astronomical numbers by realizing that this implies that for every human on the planet there are nearly Avogadro's number worth of viruses. This corresponds to roughly 108 viruses to match every cell in our bodies.
