One thing at least is certain, light has weight
Light rays, when near the Sun, do not go straight
Sir Arthur Stanley Eddington, May 1919

Above is Sir Eddington’s photograph (one of the 16 exposures taken) of the total solar eclipse of 29 May 1919 which appeared in his 1920 paper confirming that light can bend as postulated by Albert Einstein.

When I was learning Wing Chun we were taught that the shortest distance between two points is a straight line.

In science it is said that light also takes a straight line to get between two points. At least, that was the general wisdom until Einstein realized that it was not always the case.

I was reading another book in which a drawing was used to illustrate this point but I didn’t quite catch the implication. It was only on reading another book that I understood what this model meant.

Below is a drawing similar to the one I saw.

Did you get what I realized?
