Professor Simone Marzani of Manchester University will lead our discussion of the vacuum structure. Is it really “nothing at all” or is it stuffed with interesting things designed to appear to be nothing – mostly?

This session originated from our SciBar visit to the Rutherford Laboratories where one of their lasers was so powerful that its progress through the vacuum kept causing lots of virtual particles to be created “from nothing”. They thought they may be approaching the power limit for transmitting through “empty space”.

So what goes on out there where there is “nothing”?  Come along and find out.

Look left to see why there is nothing in space — the vacuum of space.
