Thanks for this direct explanation. I've been collecting such difinitive works for my website. I will check your website after this response.
My question has nothing to do with this topic but perhaps it does.
I collected the following list over a year ago and was wondering if you could supply comments or updates on it. Thankyou in advance. I don't understand the list but perhaps my readers will so no need to bring it down to my level. It's hard to find
physicists to ask such questions of. If the list is a crock then say so. Could you give me such a list that is relevant today.
The ten unanswered questions of Supersymmetry (String theory)
- Are all measurable dimensionless parameters that characterize the physical universe calculable in principle or are some merely determined by historical or quantum mechanical accident and incalculable?
- How can quantum gravity help explain the origin of the universe?
- What is the lifetime of a proton and how do we understand it?
- Is nature supersymmetric and if so, how is supersymmetery broken?
- Why does the universe appear to have one time and three space dimensions?
- Why does the cosmological constant have the value that it has? Is it zero and is it really constant?
- What are the fundamental degrees of freedom of M-theory and does the theory describe nature?
- What is the resolution of the black hole information paradox?
- What physics explains the enormous disparity between the gravitational scale and the typical mass scale of elementary particles?
- Can we quantitatively understand quark and gluon confinement in quantum chromodynamics and the existence of the mass gap?
