Why is CERN important?
The Large Hadron Collider and other unique facilities at CERN provide the necessary infrastructure for scientists around the world to gain more knowledge about the smallest constituents of matter, their interactions, and the origin and evolution of the Universe.
What countries are involved in CERN?
Today CERN has 23 Member States: Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Israel, Italy, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovak Republic, Spain, Sweden, Switzerland and United Kingdom.
Does supersymmetry exist?
There are many different ways of achieving supersymmetry, all predicting different masses for the selectrons, the stop quarks, the sneutrinos and everybody else. To date, no evidence for supersymmetry has been found, and experiments at the Large Hadron Collider have ruled out the simplest supersymmetric models.
Why does string theory need supersymmetry?
Also, the work assumes supersymmetry, which means that all the standard model particles have partner particles. String theory needs this symmetry in order to ensure the mathematical consistency of solutions.
Has string theory been proven?
No one has proved the swampland conjecture, and several string theorists still expect that the final form of the theory will have no problem with inflation. But many believe that although the conjecture might not hold up rigidly, something close to it will.
What are the 4 known dimensions?
Summary table
| Dimension | Figure | Face |
|---|---|---|
| 1 | interval | point |
| 2 | square | interval |
| 3 | cube | square |
| 4 | tesseract | cube |
What is 5th Dimension in Space?
The fifth dimension is a micro-dimension which is accepted in physics and mathematics. It’s here to have a nice and seamless tie between gravity and electromagnetism, or the main fundamental forces, which seem unrelated in the regular four-dimensional spacetime.
