- Our donors believe that discoveries made in theoretical physics are really important for humanity.
- This is certainly true if you look at the past:
- Without theoretical physics we wouldn't have modern technology and a vast array of sciences.
- We know that the world is made of atoms. Who found that out? Physicists!
- We know that atoms stick together to molecules. Who discovered that? Physicists!
- The Higgs boson, a billion times smaller that the atom, predicted 50 years earlier on the basis of quantum theory and relativity, was found in a 10 billion Euro LHC machine ...
- The second great discovery was made by the Planck satellite as a pattern of density variations from the Big Bang...very precise...although a few unknowns like dark matter and energy...
- The level of agreement between theory and data is extraordinary and not matched in any other area of science.
- Yet, what we are describing is the whole universe itself, which turns out to be very simple on very large scales and on very small scales.
- The level of precision and reach of physics is beyond any other area of science.
- That is the good news about physics: It is the most successful field in science and the most conceptually simple.
- What is is going on?
- Why is it that human beings have this capacity to see into the heart of nature way beyond the world of everyday experience?
- We don't know.
- Theoretical physics is at a crossroads.
- We have entered a very deep crisis...grand unified models, supersymmetric models, superstring models, loop quantum models, models, models...
- Nature turns out to more simple than all these models.
- Theorists are in state of confusion. What is going on?
- Theories have failed, because they did not really introduce new concepts.
- The number of parameters in supersymmetric models is 120, and explodes into thousands...
- String theory seems to predict $10^{1000}$ different possible laws of physics:
- The multiverse: The ultimate catastrophe. Crazy situation.
- Theorists utterly confused...seem to have no predictions at all.
- Very deep crisis. The vacuum is not empty...it has energy...
- Theory has kind of selfdestructed.
- The theories we know are missing some very important principle.
- You are entering a field which requires a complete re-invention.
- What type theory will replace quantum theory and relativity?
- You will need to develop your own ideas...
Note that this post connects to an earlier post on the same theme. The reason I am returning is to find motivation in my own search for new models, in which endevour I may have as good chance of finding something as any other confused physicist.
