... Our efforts were focused toward developing a quantum mechanical hypothesis for an effect already predicted by G.R., namely, how space-time is curved by electromagnetic radiation. Scientists have long pondered the relationship between electromagnetism and gravity, and have also sought to unify Q.M. ...

EXPOSITION OF TIME

... The time begins at the moment of the Big Bang, as the previous times are not defined… God may have created the Universe at any moment in the past. However, if the Universe is extending, there might be reasons why it has started to extend. We can still imagine, that God created the Universe at the mo ...

It then becomes immediately obvious that the influence on the standard results of the Euler force, which modifies the effective gravity by d2c/dt2, is utterly negligible. Of course one can choose the alternative route attempted by Wolff and Patrone of rema ...

A Study of the Nature and Representative Features of Supernova

... (Galactic) supernovae remnants exist, with a few dozen other heavily suspected. For a listing and summary see Green D.A. 2001. The remainder of this paper will focus on Galactic SNRs since they are the most accessible and easiest to study. The first extragalactic supernova was not observed until 188 ...
