A Universe Smaller Than A Marble

Scientists at Lancaster University have created a Universe (or something very much like it).

It lies at the bottom of a chamber no bigger than your little finger, filled with helium and cooled to 0.0003 degrees Fahrenheit above absolute zero.

'By placing helium in a state which most closely resembles the form it held at the beginning of the universe, scientists have created an opportunity for the gas to go through several low-energy evolutions. These defects in space-time, are represented by tiny whirlpools in the helium, which are created by the rapid expansion, and equally rapid slowing of the expansion; something that it’s believed our own universe did at the big bang and in the moments thereafter.'
