This unlocked a song that has been buried in my mind for YEARS:
Now some of you may think that gravity is strong
Cuz when you fall
Off your bicycle
It don’t take long
Until you hit the earth
And you say, “Dang that hurt!”
But if you think the force
Is powerful
You’re wrong
You see, gravity
It’s weaker than weak!
And the reason why
Is something many
Scientists seek
They think about dimensions
We live in just three
But maybe there are others
That are too small to see
It’s into these dimensions that gravity extends
Which makes it seem weaker here on our end
And these dimensions are rolled up, curled so tight
That they don’t affect you in your day-to-day life
But if you were as tiny as a graviton
You could enter these dimensions and go wandering on
And they’d find you…
Yes, it’s the obvious extension from what we have now, and quite coherent for explaining some universe that isn’t the one we live in.
It just shouldn’t have monopolized theoretical physics for a generation. It’s really hard to imagine something different, but this is even more reason to celebrate the people trying that, not to shun then and focus on what you already have.

LHCb sees where the antimatter’s gone, ALICE looks at collisions of lead ions
Oh, a song from the time superstrings were still cool?
A brave little theory, and actually quite coherent for a system of five or seven dimensions — if only we lived in one.

“Gravity is weaker than weak” is such a strong line.
Wasn’t this in Particle Fever? That doc is incredible.
