Okay. Thank you everyone for the replies. This clears everything up and hopefully someone else finds/found it useful too.

What's interesting is that a quick scan of history in say the american culture (where we have had the focus on rap, rock and roll, television, money, sex, and the bazillion other things that don't even come to mind right now) shows us that these studies keep popping up with the same underlying...

Let's say you have two batteries in parallel and at the same voltage. Well batteries fluctuate in voltage and when they are drained they will have a somewhat lower voltage than what they started with when fully charged. Because of this, when power (or current rather) is being drawn from a...

Ah, okay. I think I understand now. So I shouldn't think of mass as 'occupying space', but as a construct to describe a mathematically observed difference between differing objects due to gravitational forces. So when I think of photons not occupying space, that is incorrect to say, in this...

Thanks for your responses. I guess I'm having a hard time accepting this since I can't think of all the energy of the world around me in terms of a 'unit of space' or 'unit of some physical size'. I don't know how to imagine photons if they don't occupy a space and thus have some kind of mass...

Hello, I'm quite confused about something. Maybe you all can help :) I'm not sure I understand why the science community seems to assume photons have no mass. I can understand how it wouldn't make sense to say a photon has mass by the mathematics that is used to describe the energy of a...
