Bringing the universe down to earth

Dr Peter Edwards from Durham University

17th June 2022

Dr Peter Edwards from Durham University gave a talk over Zoom

Talk entitled Bringing the universe down to earth

Dr Edwards started this interesting talk with an experiment of dropping a ball several times and asking why this was and saying it’s all down to gravity.  Isaac Newton wrote about gravity.

Distance, further apart the weaker the gravitational force.  Closer together the stronger gravitational force.  Mass, greater mass the greater the gravitational force.

Many galaxies have many stars which pull together to form clusters and Dr Edwards said that gravity can be traced back to super particles.

Big Questions

Where do we get our mass from?

What produces most of the gravity in the universe?

What happened in the Big Bang?

What is mass – Peter Hicks

Property mediated by Hicks Field – the following examples were given:

Barracuda in the ocean – lighter mass, Hump Back Whales in the ocean – heavier mass.

 

Hicks Field shake hard enough to create particles.

Hicks Bosons

5% atoms

27% Dark Matter – missing gravity can’t see them

68% Dark Energy – no idea what it is

What is Dark Matter – unknown substance (not an atom) maybe a fat cousin been around since the Big Bang.  How do we find answers, time machine emulating the very start of the universe?  Beginner’s guide take some protons and make them move.

LHC took 30 years to build, the accelerator takes electric waves to spread the particles and magnets bend them round in a circle which is 27 km long compare this to the Circle Line of London Underground which is just about 22km.  LHC super conducting magnets have a working temperature of -271C which is colder than outer space, 37,000 tons of metal colder than the universe.  1 billionth of a second after the big bang – bashed the protons together this to 3,000 scientists and engineers to build it.  There are 4 experiments at Cern, detectors reconstruct the debris from the collision. Detectors are cameras at about 100mg pixel resolution which takes 20 million pictures per second.  Atlas is the largest detector which will just fit inside Durham Cathedral and it was explained that the detectors have layers like that of onions.

Finding out answers by recreating the early universe (LHC) and observe what happens even mini black holes. LHC is not a doomsday machine do not panic, its 10 years since the discovery of the Hicks if it is a field it should have a particle assigned to it.

Run 2 its time to break physics, Higher energy more than 1.5 times greater – it was switched of 2 years ago – and still analysing the data and it is just about to be switched on again.

What will we find

Dark Matter                       Extra Dimensions

Antimatter                          Super Symmetry

It is a discovery machine.
