RE: New phenomena in particle physics - searching for our dear SUSY (aka supersymmetry)
One question, when you say “And as a result, the three fundamental interaction couplings unify at a scale roughly lying three orders of magnitude below the Planck scale. We have now an energy regime where three of the fundamental forces can potentially unify.” is it then that that Gravity is the only fundamental force left over, and if so what happened to the other 3 forces. Did they rap space into a black hole. I did not know that there are magnitudes below the Planck scale. I thought that was the smallest unit, or is that just for the Standard Model.
It actually depends which Planck scale one is talking about.
What I call the Planck scale is the Planck energy scale which is huge, roughly equal to 10^19 GeV. The unification scale is thus roughly 10^16 GeV. And for the sake for the comparison, the scale probed at the LHC is roughly of 10^3-10^4 GeV. We still have a long way to go.
You can always convert the Planck mass into a Planck length by adjusting a prefactor depending on the Planck constant and the speed of light. And this one is small, as a length is the inverse of an energy in the unit system commonly used in particle physics.
I have edited my post to make this clearer. Thanks for reading it, and pointing it out!
