Welcome to Crowd Science from the BBC World Service, where this week we're taking.
You on a little journey.
And when I say little, I mean really, really tiny.
Imagine that you shrink yourself by even a factor of 100.
I'm Anand Jagatiya, and this is cosmologist Andrew Ponson.
Okay, so now you're around about the size of an insect, say, and you can imagine already.
I mean, the world just seems so different if you shrank yourself just by a factor of 100.
Andrew is shrinking us down to minuscule proportions so that we can zoom right into the smallest parts of our world.
But we are a very, very long way away.
So if we shrink ourselves by another factor of 100, at this point, we're around about the size of the width of a human hair.
So if you shrink yourself down, you're now sort of lost in this forest of human hairs, and the world would seem a very, very frightening, very different place.
But we've still got a long way to go.
We're going to shrink down by another factor of 100.
Now, you're one micrometer across.
That's around about the size of a bacteria.
So now all of the kind of living world around you would be constructed out of these bizarre creatures that, you know, we can't see.
