The Difficult Birth of the “Many Worlds” Interpretation of Quantum Mechanics
Hugh Everett, creator of this radical idea during a drunken debate more than 60 years ago, died before he could see his theory gain widespread popularity …

If I think about the quantum theory and about the general theory of relativity, I feel a special difference in the way they are built. The theory of relativity is derived with the help of the concept of “local inertial frame” – therefore I expect that the theory will hold for systems which can contain an observer. To the contrary, the quantum theory is derived via the concept of an external observer – therefore I expect that it will hold for systems which cannot contain an observer. We can imagine the relativistic system as a big one and the quantum as a small one, but it is not necessary.
