And the largest? The distance of the most distant QUASAR in nanometers! Or picometers!

How about in yoctometers?

The smallest: the distance traveled by an object, moving at 1 yoctometer per yottasecond, in one yoctosecond.

]]>OK. So maybe I should find some way of making it possible for you to post here.

Anybody have any idea what the smallest distance knows is?

And the longest?

The smallest distance? The radius of an atom! Or still better, the radius of a quark!

And the largest? The distance of the most distant QUASAR in nanometers! Or picometers!

That would still be much larger than a googolth!

I have Metric Numbers, but maybe I could add some more examples?

I think yes, because Nano, Pico, Femto, Atto etc. may not be there!

]]>A yoctosecond is probably the time it takes an electron to make 1/10^99 of a revolution around its nucleus.

Measures are odd in that they may seem to be infinite, but they have a finite nature to them; there is a point at which a measure is so small or large that it is meaningless. For example, a yoctosecond (20^-24 seconds) is so short that nothing can happen during that time, therefore, it is meaningless. On the other hand, a yottasecond is longer than the current age of the universe, so it's pretty meaningless; it's longer than the time it would take a photon to go one yottameter.

Yocto: 10^-24

An atom is roughly between 10 and 100 nanometers across.

A quark is roughly 10 to 100 femtometers across (I said elsewhere that it was 1 or 2 attometers, but that was exagerated).

An exameter is roughly 9000 light-years.

A petameter is about 9 light-years.

As for the mostrecent additions to this list (Yotta, Zetta, Zepto, Yocto), they are beyond comprehension as far as measures go (the truth is, I can't really find anything to put them in perspective).
