In his old age, Einstein became an atheist in the religion he founded. He came to the conclusion that Relativity and Mathematical ‘physics’ in general were nonsense:
“All these fifty years of conscious brooding have brought me no nearer to the answer to the question, ‘What are light quanta?’ Nowadays every Tom, Dick and Harry thinks he knows it, but he is mistaken… I consider it quite possible that physics cannot be based on the field concept, i.e., on continuous structures. In that case, nothing remains of my entire castle in the air, gravitation theory included, [and of] the rest of modern physics.”
(letter to Besso, August 10, 1954) in A. Pais,, p. 467
His disciples were so offended by Einstein’s change of heart that they isolated and ostracized him. As part of this process, they made Einstein a reluctant hero of General Relativity…
“I am generally regarded as a sort of petrified object, rendered blind and deaf by the years.”
(letter to Born, April 12, 1949) A. Pais,, p. 462.
“I have become an obstinate heretic in the eyes of my colleagues…”
(letter to Besso, August 8, 1949) A. Pais,, p. 462.
Einstein had realized in his latter years that the physical interpretations that Mathematical ‘physics’ offered for micro and macro phenomena were surrealistic and irrational.
Followers of Einstein usually are ignorant of his change of heart or downplay his ‘unfortunate’ latter-day conversion. Instead, they credit him for just about everything, including: black holes, gravity waves, and Big Bang in spite of the fact that Einstein wrote papers against each of these proposals:
Against black holes: On a Stationary System With Spherical Symmetry Consisting of Many Gravitating Masses (1939)
Against gravity waves: On Gravity Waves (1918)
Against Big Bang: On the cosmological problem of general relativity (1931)
Einstein also refused to believe or accept the surrealistic physical interpretations of Quantum Mechanics…
