How the LHC works – demonstrated with mince pies.

The Large Hadron Collider appears frequently in the science news, and is certainly no stranger to this blog. It is the biggest particle laboratory ever built, and possibly the most significant Physics experiment of all time, so that’s kind of understandable.

But, for those of you who are slightly unaware or unsure of what the LHC is, what it does, or how it works – fear not. Here is Professor Heinz Wolff, explaining how the Large Hadron Collider works in simple terms – using mince pies.


LHC may make time travel possible … to particles at least

It can accelerate particles to within a fraction of the speed of light. It can re-create the conditions of the Universe when it was less than one second old. It aims to find the Higgs boson and produce a grand unification theory, thereby changing Physics forever. Now, the latest theory is that it will make time travel possible. Is there anything The Large Hadron Collider can’t do? 

It should be noted that this theoretical “time travel” will occur only on the microscopic scale, so the LHC won’t become a magic tunnel where people can dive in head-first and visit the Stone Age or the year 3000. However, it will produce particles that can hop between the past and future: some scientists believe that if the LHC can produce the Higgs boson, it will create another theoretical particle called the Higgs singlet, which can jump into an extra fifth dimension, thus being able to move forward or backward in time.

The scientists proposing this theory admit it is “a long shot”. However, the theory is kept alive as “it doesn’t violate any laws of physics or experimental constraints.” And it remains an exciting theory, as information and messages could be sent to the past or the future if production of Higgs singlets could be controlled.

The mind-blowing image of the sun blowing its top

It looks so beautiful, so calm,  so intriguing – and yet it is a photograph of something so violent and explosive. Astronomical photographer Alan Friedman captured this image of “Sun Spots” – massive eruptions taking place on the Sun’s surface.
