[QUOTE="Janx, post: 6043872, member: 8835"] Conceptually, when we observe stars, we are looking at their state from millions of years ago (1 year in the past, per light year). technically, the star was broadcasting the info, and we just happen to catch it in the future. Though by Umbran's more technical assertion, we did not actualy go back in time and capture that info (thereby removing that energy). I suppose what Umbran means my Information = Energy, and what most of us mean might also be different. If I could go back and watch Licoln's assasination, the rays of light in the room are bouncing around and hitting me and my eyes, where previously there was an empty gap. I can assert that my brain is merely copying the information of what happened, but technically, I was blocking somebody's view of the play, and "taking" energy from the event. Us layman see that as a pretty passive event. Especially if I stood someplace out of the way. Scientists who pay attention to observation protocols would probably nitpick it based on the concept that the act of observing tends to interfere, if only slightly in the event being observed. Plus, I recall some phenomenon in quantum physics where you tend to find what you were looking for, but that trended toward hippy quantum physics. [/QUOTE]
