[From “Where Is the 1919 Data Proving General Relativity?”]

If I do a search on the Internet with the expression “Genius of the 20th Century”, almost certainly the first entry on the list will be Albert Einstein (1879-1955). Einstein won the Nobel Prize in Physics in 1921 “for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect”1. However, he is best known for his theories of special relativity (1905) and general relativity (1915)

Einstein became world-famous as a result of observations made during the May 19th, 1919 solar eclipse, which was visible in the tropics[…]
The analysis for the Príncipe observations was conducted by Eddington, while that for the Sobral observations was overseen by Dyson. It was concluded that the observations from the Príncipe telescope and from the 4-inch diameter lens in Sobral confirmed Einstein’s predictions[…]
Wait, what? Neither Eddington’s data analysis sheets nor his photographic plates have survived?[…]
This is for the observations that proved without a doubt that classical physics was wrong, and made Eddington a star and Einstein a superstar! So today we have no physical evidence that Eddington actually observed what he claimed to have observed[…]
Nevertheless, when the raw data from one of the most famous set of observations in human history has gone missing, one naturally speculates, What is going on? So, the topic of relativity, both special and general, will likely be the subject of numerous future posts
