But this is true for every physical quantity. Hence, if one claims that "no one knows" what energy is, this also applies to all other quantities like mass, momentum, charge, time, etc. There's no fundamental difference between our knowledge of what energy "is" and, say, our knowledge of what charge "is.". | |
