How small is the Universe
Splitting the Atom, was the easy bit!
Horizon - Miniature World
Handheld Universe
Astronomers have long tried to understand our planets as tiny specs in the vastness of the universe. But there is another expanse of the universe to explore, a bizarre realm in which we are giants, the weird world of the very small.
This is a journey into the heart of matter, a journey down the biggest rabbit hole and history…
"It's perfectly possible that in the high-energy end of our data, right now we are occasionally making miniature black holes."
The journey smaller than you can see, smaller than an atom, where nothing is what it seems…
"The more fundamental things are, the nicer it is to look inside them."
Into a wonderland which seems far removed from reality…
"Gravity is looking into the extra dimensions."
Down to the very smallest structure of the universe.
"We should expect space time to be not smooth as we presently imagine, but more like the foam of a cappuccino."
The journey to find the smallest thing may take us into another universe altogether.
"But then of course, when you're down to this scale, you may have the whole universe in your hand."
And at the bottom of the rabbit hole, you may find that our universe is just one of many.
