Are you aware that many highly qualified people do not agree with Einstein’s general and special relativity?

Einstein was a mathematician, not a physicist, and did not subect the results of his thought-experiments to the laboratory tests physicists use: testable hypothesis, test, and confirmation.

One enthusiastic but poorly-informed relativity defender told me relativity is built into cell phones. I corrected him with “A mathematics that approximates relativity is built into cell phones” and he caved.

For another instance, try producing a testable hypothesis that an object’s mass increases to near infinity as its velocity nears the speed of light.

His biographer, Walter Isaacson, wrote of Einstein’s rebellious nature. Whether or how it affected his work is not known.

Remember, no one has ever found a god walking among us.

Theory of relativity is confirmed 100 years later on numerous occasions. He was pretty smart.
