IT'S an ambitious task, recreating the universe in a bucket. But if it is successful, the experiment could help solve the twin puzzles of why we're made of matter rather than antimatter and where the huge magnetic fields that span galaxies come from.
At last month's Cosmology Meets Condensed Matter conference in London, it emerged that space-time could be simulated in the lab using weird substances known as "superfluids", which flow without resistance and can even climb up the walls of jars. Intriguingly, the equations governing the particles inside superfluids are similar to those that represent the early universe, says Ray Rivers at Imperial College London. "We hope that we can use these to check things in the lab that frankly we don't have any hope of seeing through astrophysical observations."
Tanmay Vachaspati at Princeton University thinks that studying superfluid helium-3 could help solve two mysteries: why the ...
