How small is the Universe – Small 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. Which profers the question: How small is the Small Universe.

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 small universe is just one of many.

Splitting the Atom was the easy bit
We all remember, from science lessons at school, about splitting the atom. We were taught about protons neutrons and electrons, we were also taught that these basic elements could be divided no further. These teaching were not the full story. We find out now that with advances in science we can peer much further down into the world of the very small; to learn about far more fascinating phenomena.
