Do you know the magic number of the universe?

What number?

One over one hundred thirty-seven?

That's so random...why?

It's not random! It tells how light and electrons talk to each other

...light talks to matter?

Yes, without 1 over 137, atoms would not even hold together. No chemistry, no life.

So, no me, no you?

Exactly. No stars, no music, nothing.

That sounds impossible.

And yet, it's real. A pure number with no units. Scientists call it alpha...

Alpha 137
