I'm back from a business and vacation trip. One of the highlights was a highly interesting and impressive visit to CERN's experiments Atlas and LHCb. This picture was taken about 100m underground. You can get a sense of scale by looking at the two workers on the blue spot at the bottom right of the picture.
"Fourteen billion years ago, the Universe began with a bang. Crammed within an infinitely small space, energy coalesced to form equal quantities of matter and antimatter.
But as the Universe cooled and expanded, its composition changed. Just one second after the Big Bang, antimatter had all but disappeared, leaving matter to form everything that we see around us – from the stars and galaxies, to the Earth and all life that it supports.
LHCb is an experiment set up to explore what happened after the Big Bang that allowed matter to survive and build the Universe we inhabit today."
