They seem to have maybe found a Higgs-like boson,probably…

I wrote about the Higgs boson discovery in Scottish Times today.

Higgs boson: what is this ‘God particle’ and has it finally been discovered?

The LHC which was used to discover Higgs

What has happened?

This morning, scientists working at the Large Hadron Collider (LHC) base in Cern, near Geneva, have claimed to have discovered a subatomic particle consistent with the Higgs particle.

In other words, they seem to have found evidence of a particle similar enough to Higgs to name this the ‘Higgs discovery’. This may not sound definitive – it is a Higgs-like boson rather than the Higgs boson – but it is certainly big news for science.

The elusive but crucial particle was named after British theoretical physicist Professor Peter Higgs, an emeritus professor at the University of Edinburgh (the word ‘boson’ is just the name of a certain kind of subatomic particle).

Director-general of Cern’s European Organization for Nuclear Research, Rolf Heuer, commented: “I would now say I think we have it. We have a discovery – we have observed a new particle consistent with a Higgs boson. But which one? That remains open. It is a historic milestone but it is only the beginning.”

For the last 45 years scientists have been trying to explain how matter gets its mass and it is thought that this kind of particle is key to the explanation. Professor Peter Higgs wiped a tear from his eye as the teams finished their presentations in the Cern auditorium to loud applause and cheers this morning.

Elsewhere today Professor Stephen Hawking said that the discovery has cost him $100, as he placed a bet with a Professor at Michigan University that the Higgs boson would not be found in his lifetime.

The Universe is Expanding?

I’m doing a beginners’ astronomy course at the moment. It just covers the basics and, having an interest, I have read a thing or two about cosmology and astronomy previously. But last week blew my tiny mind a bit – our lecturer is a physicist who believes the universe is NOT expanding. Arghhhhhhh…if the universe is not expanding, then there was probably no big bang…aarghhhh… Continue reading
