I feel i need to ask this fundamental question, because everywhere i look i just get a very bland definition with no discussion.
So what actually IS energy? Is it just a mathematical thing that we have worked out that just works in a kindo of"number crunching" fashion, or is it more fundimental than that, more like an "entity" of some sort? I don't see how it can just be a number cruching principle, since in relativity, mass is converted to energy and vice versa - is mass if lost then i must become SOMETHING - that something is obviously energy but, but what is energy?
Please feel free to discuss this and elaborate on this as much as possible - I feel that it is a key part of physics to really unddertand properly.
Thanks in advance.![Wink :wink: :wink:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
