Hello, Brian Cox.
I have only one question for you: In macroscopy, and more particularly in the context of Einstein’s General Relativity, Is this the mass of an object like the Earth or the Sun or would it be the electromagnetism emanating from these objects who curves the space-time? Thank you for your reply ! Mass or E.M?
