...confident that the technical yardstick by which they measure distant galaxies and quasars-the red shift of light from those bodies-is reasonably accurate. And by that measure, the most distant quasar so far observed by astronomers is about 8 billion light-years away. Furthermore, in the complex Einsteinian geometry of space, diameter is a naive measurement; normal concepts of shape are meaningless. Astronomers were also nettled by the way that NASA released its information. Ignoring the scientific community, the space agency has to date published its conclusions only in a press release that was issued on the first anniversary...
Tedious Trip. Spurred on by that hemmed-in feeling, Feinberg brazenly began questioning the inviolable Einsteinian speed limit more than a dec ade ago. But no matter how he analyzed the set of mathematical equations that define relativity, he could not es cape the conclusion that matter cannot be accelerated to the speed of light, to say nothing of higher velocities. The equations showed that at the velocity of light, the mass and energy of any ordinary particle would become infinite -a clearly impossible situation. Beyond it, his mathematics suggested, the mass and energy of the particle can only...
Negative Answer. A Faustian universe can even be justified mathematically, says Stannard, because the Einsteinian equation that expresses the time of one observer relative to the time of another observer moving at a different speed involves a square root. The square root of any number, he points out, can be a positive or a negative number. "What I suggest," says Stannard, "is that we accept the minus answer as a possibility. Thus we get negative, or Faustian, time...
...calculations made by Stanford University Physicist Leonard Schiff, the gyroscope should precess-change the direction of its axis of rotation-about 1/500th of a degree each year that it is in orbit. This gradual and almost imperceptible change would be caused by the continuous passage of the gyroscope through Einsteinian space, which is "warped" by the earth's gravitational field...
...raises such questions as whether the universe came into being suddenly, or whether it existed forever-and in that case, what is "forever"? What is eternity? "The subject," says Science Writer Leon Jaroff, "makes the mind boggle, especially when you get into the area of cosmology, into the Einsteinian concept of space...
