Energy increases and entropy diminishes in an opening system. Where is the mass in a 2-dimensional single-sided only (one-sided only) entity? Where is the mass in the strictly 1-dimensional string (the strictly 1-dimensional arrow) of the "observable universe"? Light does not build up to c, it has no momentum (its sources have momentum -- including absorption masses), it starts there (c) and ends there (c) and is measurably c on the spot at any local point of duration (the speed of light is constant in a vacuum). It is at 'rest' at c (photo-time-stopped), equal and opposite to mass at 'rest'. Mass has been converted to energy (past tense! past tense! past tense!), a completed change of one dimension to another (a greater dimension to a lesser dimension (brought down in complexity)), it's not being converted (it's no longer in process (e=mc^2....whatever)). GLB =====================

That number would be determined by *measurement*. You don't look at a formula and decide what the value is by looking at the formula. Tell me, Porat, surely you've learned Newton's second law: F=ma. Can you tell by looking at that formula whether a is zero or nonzero? Does the formula only apply for one case or the other? Please be careful in answering this question. > > are you out of your mind ?? > if m was zero > th e formula should be > > E^2 > = 0^2 plus ( o ) ^2 No, because the pc term doesn't have anything to do with mass. pc has the same dimensions as mc^2, but this doesn't mean that you can use the number of m in the first term to tell you anything about p in the second term. You said this yourself. Just because the dimensions are the same does not mean the values are the same. > there was a Turkish Admiral > that was sent to a mission in the iland Malta > but the poor Admiral lost its way > so he came back to turkey to his Boses > and declared > > MALTA YOCK !!! > (Yok in Turkish is disappeared ) .... > > Keep well > Y.Porat > -------------------------------- > > BYE > Y.P > ------------------------------- |
