Testimony by Leading Physicist Leonard Susskind

Leading theoretical physicist Leonard Susskind sums up his experience at the end of his career as follows:

• I can tell you with absolute certainty that String Theory is not about the world we live in.
• We have to describe our world. That is our purpose.
• So we need to start over. We have a lot of work to do. I do not know of any young people doing that. 
• String Theory combines quantum mechanics and relativity in a very beautiful way. There is no other theory that reconciles quantum mechanics and relativity. 
• String Theory does not describe the real world. 
• Is there anything else? Not to my knowledge.Wolfram's hypergraph is a failure. I do not know who Eric Weinstein is. Penrose believes in all sorts of stuff that I do not believe in.
• So we need to start over again.
• To students: Think for yourself and do not listen to old people. What should you work on? I don't know and if I knew I would be working on it myself. Don't be afraid, follow your curiosity. 
• If you do not think that you can do that, you are probably in the wrong field.
• So we need to start over...

What can we get out of this? Well, yet another confession that modern theoretical physics is in deep crisis.

Anything new? Yes, Real Quantum Mechanics is in perfect harmony with Neo-Newtonian gravitation/cosmology. Don't be afraid to check out. Do not listen to old physicists.
