Questions about the relationship between the metric tensor and the gravitational field In the linear approximation, the metric tensor g^uv is related to the gravitational field h^uv according to (k=sqrt(16 pi G)): g^uv = eta^uv + k h^uv (1) Further, the "graviton" field psi^uv is related to h^uv according to (what is the best thing to call psi^uv, in contrast to h^uv?): psi^uv = h^uv - .5... 18 Nov 2009 12:21
Einstein "fingers" and relativity I remember once I read some comments from Einstein himself in which he somehow said that he could imagine what happen with space/time through some weird play with his own fingers. Seriously. I am a theoretical physicist myself and to me that was a very weird, confusing and unpedagogical thing to hear, but I found ... 10 Dec 2009 23:24
There is no time dilation or physical length contraction. There is no time dilation. 1. Clocks in different frames runs at different rates. 2. A clock second does not represent the same duration (absolute time content) in different frames. In other words a clock second is not a universal interval of time in different frames. There is no physical length contraction. 1.... 23 Nov 2009 15:15

Dogs of CERN’s Boss threatened to put me into jail. Dogs of CERNs Boss threatened to put me into jail. Yesterday some man, possibly from Rolf Heuer environment, had phoned me and asked did I threaten to Heuer. The conversation was ended by the threat to put me into jail and by saying that our phone conversation was recorded. Dear CERN leaders, I feel myself ... 16 Nov 2009 11:17

Simultaneous events and accelerations - contradiction? The following seems contradictory. There are two identical rockets separated a distance L as measured on the x-axis in an inertial reference frame. Let the two rockets be on parallel lines to the x-axis. An observer in a frame moving at V relative to the x-axis turns on the thrusters of both rockets simultaneou... 9 Nov 2009 17:46
Riedt vs Einstein Riedt vs Einstein Einstein's first postulate of Special Relativity (Principle of Relativity): The laws of Physics are the same in all inertial systems.

An Absolute Chronometer An Absolute Chronometer If the space between observers here on earth and a distant optical source were a perfect vacuum then the speed of the light rays coming from that source would depend only on the motion of that source compared to our position or motion. In that case, time dilation and frequency shift would... 8 Nov 2009 22:59 |
