"Fantastic discovery" is thought to be Higgs Boson
The latest results from CERN’s Large Hadron Collider (LHC) in Switzerland further reinforce the idea that the particle discovered last year is a Higgs’ boson.
The until now theoretical, illusive matter was the dreamchild of the Bristol-born Professor Peter Higgs, who went to Cotham Grammar School in Bristol.

Having analysed more data, the CMS and ATLAS experiments at the Large Hadron Collider (LHC) have today presented their latest findings at the Moriond Conference in Italy. They find that the particle is looking more and more like a Higgs boson, the particle long-thought to give other particles mass.
Dr David Newbold, who leads the CMS team at the University of Bristol, said: “After last year's fantastic discovery, there's been an intense effort to measure the properties of the new particle in detail. We now have twice as much data as in 2012, and we've begun to explore whether this really is the boson predicted by Peter Higgs and his colleagues almost 50 years ago.

“So far everything looks consistent with the predictions of the Standard Model, which of course is a triumph in its own right – but there is the even more exciting possibility that the new particle is an 'imposter' that could point the way to new laws of physics. The full picture will only become clear when we restart the upgraded LHC in 2015 with double the current energy.”
If the new particle is a Higgs, it could be the Higgs as predicted in the 1960s, which would complete the Standard Model of particle physics, or it could be a more exotic particle that would lead us beyond the Standard Model.
The stakes are high. The Standard Model accounts for all the visible matter in the universe, including the stuff that we are made of, but it does not account for the 96 per cent of the universe that is invisible to us – the so-called dark universe.
Finding out what kind of Higgs it is will rely on carefully measuring the particle's interactions with other particles, and that may take several years to resolve.
UK particle physicist and ATLAS Spokesperson Professor Dave Charlton said: “The latest results mark a significant step in the measurements of the new boson, and use the full data sample collected so far by the LHC.
“It has been a great challenge for the experiments to produce such detailed analyses so quickly – it is a testament to the dedication of very many people that we could show them this week. With these results we see both that the decays, and the spin quantum number, of the new particle look like a Higgs boson.”
Another Bristol connection with the LHC is husband and wife team Greg and Helen Heath, from Bristol University, who have been working on the project for 20 years.
Dr Helen Heath works on a part of the detector which measures the energies of electrons and photons (particles of light), while her husband Professor Greg Heath works on a system that decides which single event is stored.

“New and old Science
In spite of two findings from Einstein and Planck, one to show the equation between atoms and energy and the other to discover the constant between waves' frequencies and energy, traditional science has never closed the circle. Still today, science does not recognize the transformation from waves to atoms.
A new and Progressive Science shows how Wavevolution, or the transformation from waves to atoms, is the connecting link that closes the circle of science to open our eyes toward new horizons never seen before.
The bureaucracy of traditional science prevents the recognition of any event unless certain criteria are first met. The problem of this science is buried deep in the compilation of these "laws" or criteria like the "uncertainty principle" introduced by a few scientists in the name of all science and from their erroneous understanding of the relation between Space and Time. This antiquated system of rules also results in misleading theories.
For example, Space is not "curved".
In Einstein's paradigm, a stone that falls on the ground from the window of a moving train also marks one parabola in Space. Although, this path is only apparent since the Earth is also moving and the Time spent by the stone to reach the ground has also changed to some degree that imaginary vertical line. At the Time of the initial Movement when the stone falls from the window its potential trajectory is one perpendicular Space that is no longer the same as the stone continues to move until it hits the ground. If the scientist had known that the coordinates of Space in Time are unique and unrepeatable then all the rest would have also been "straight". That perpendicular is straight but accounted as "curve" because of the limits imposed by the old science that makes it impossible to recognize the concept of simultaneity. In reference to each body at any moment in Time there are always only two coordinates in Space for one perpendicular.
And with two coordinates there is no curve.
One perpendicular is unrepeatable and never the same because while the measure of it is repeatable and any measurement can be applied for different segments instead one perpendicular marked in Time will never again have that same spatial positioning. The perpendicular changes in Time but Einstein believed that the concept of Space is independent from the concept of Time.
Another example is in the special theory of relativity which denies all absolutes and meanings of truth. This is in regard to Einstein's example of two beams of light hitting one same embankment of a railroad on two Points: Point A and Point B. In between the two there is also the middle point, Point M. If one train were to run over that track then on the train we would also have Point A1 on the wagon of the train correspondent to above Point A and also one other corresponding Point B1right above Point B. We would also have on the train the corresponding Point M1 above Point M. Einstein's theory is that as for Point M (not moving because on the embankment) those two beams are simultaneous and equidistant, instead, for the passenger sitting on M1 and moving towards Point B1 (and also toward Point B) the two beams are not simultaneous because the beam in Point B1 is being approached by the moving train, therefore closer to M1. In this example, while Einstein's concept of Time is rigidly kept unchanged in regard to the embankment, instead, the concept of Space is extended also to the next moment in Time when the traveler will move even if in that precise instant the traveler has not moved yet. Since the concept of simultaneity had been put aside, Einstein considered Time to be the same while Space instead had changed.
Also, this same scientist erroneously believed that all colors in the light spectrum travel at the same speed. Much confusion comes from these approximations.
