Zooming across time and space simultaneously with superresolution to understand how cells divide

2. That's kinda because ... there's always more one could know about everything

There was a time when it was a great revelation that all matter was made up a collection of fundamental atoms (elements) like hydrogen, helium, lithium, etc.

Then it was determined there were protons and electrons in atoms, valency states were discovered, etc.

Then science tried to break these down further into more fundamental entities like quarks and tried to understand those.

There's always 'more to know' as you delve further and further into the minute details of how something (anything) in the universe operates, on very, very microscales.
