Parametric Invariance of the Relativistic Coordinate Pulsar Time Scales Arkady Avramenko Pushchino Observatory of the P.N.Lebedev Physical Institute RAS, Russia The accuracy of modern astronomical observations so high that in order to understand what we see and how you can, you must use meaningful relativistic models of the observable processes. ... The numerical values of the observed rotation period are coincide in any coordinate systems at the same epoch of local time. ... Pulsars and Time Scales. ...

... Mark Jaworsky will present one early next year. ... It is theorized that Dark Matter is responsible for holding galactic (Program, continued on page 3) (Program, continued from page 2) systems together and that without it, galaxy-mass structures just would have not come into existence. ... Researchers use the theory of Dark Matter to explain this discrepancy. ... The standard theory of gravity still applies and dark matter still exists, but somehow the dark matter emulates MOND. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
