reports
that the Sagnac effect has been observed in neutron interferometry. The
coupling of the neutron to the gravitational field has also attracted interest
as it offers a way of testing some of the connections between gravity and
quantum fields. The effect of the Earth's gravitational field manifests itself
when the interferometer crystal is rotated around a horizontal axis in
such a way that one beam path experiences a higher gravitational potential
[energy] that the other. The induced phase shift therefore contains
terms of both gravitational and quantum mechanical origin. Neutron interferometry
also permitted the observation of the Sagnac effect, which is
the phase shift between two paths oriented in opposite directions about
the Earths rotation axis. The Sagnac effect cannot be explained by the
theory of relativity and it also cannot distinguish whether the earth is
rotating inside the universe or the universe rotates in the opposite direction
about the earth. When contrasted with the Michelson-Morley experiment
which failed to find the motion of the earth about the sun, the Sagnac
effect becomes a potent experiment in favor of the geocentric
hypothesis. Now its been observed using neutrons, too.
Hubble trouble
As every thinking, educated person knows, evolution is a proven
fact and the universe was formed in a big bang some 15 billion years ago.
So what if the oldest stars in the Milky Way are supposed to be 12 billion
years old, we have plenty of time to fill in those minor gaps in the theory.
Or do we?
The Hubble space telescope now confirms evidence that the oldest
stars are older than the universe. A team of researchers have looked at
the galaxy, Messier 100 in the Virgo cluster of galaxies with the Hubble
scope, in particular, looking at Cepheid variables. The properties of
Cepheid variables (the most famous is Polaris, the pole star) are well
defined and thus they are used as a cosmic distance ruler. The Hubble
telescope has thus been used to refine the Hubble constant, the unit
held as a measure of the expansion rate of the universe.
For several decades now, pressure has been on to lower the value of
the Hubble constant and to keep it well below 50 km/sec/megaparsec (1
megaparsec = 3.26 million light years). The Hubble scope places the
value at 80 (between 63 and 97). This gives an age in the range of 8 to
12 billion years. Globular clusters have ages estimated at 16 billion
years.
Be careful in claiming this a death-knell for the big bang, however.
Other lines of evidence point to values of 25 to 55 indicating an age in
the range of 18 to 20 billion years. (Earlier this year8 we looked at the
Hubble constant from a young-age universe perspective.) Besides, the
Hubble constant is not necessarily an expansion rate for the universe as a
whole. It may be local value which is far different from a universal one.
Still, it's one more piece of evidence. Actually, the Hubble constant is itself
a piece of evidence for geocentricity since it is the same in all directions
centered on the earth.
Old stars may not be so old after all
Above we noted that the assumption that stars in elliptical galaxies
are old may have led to the erroneous conclusion that our region of the
universe is being drawn into the Great Attractor. It is the standard
astronomical assumption that any region of stars which contains little or
no dust is a region containing old stars. Thus it has been assumed that the
stars in the bulge of the Milky Way must also be old. A study by Jon A.
Holtzman of Lowell Observatory in Flagstaff Arizona, using the Hubble
Space telescope, has now shown that the stars in the Milky Way's bulge
may only be middle age instead of old, if, that is, the assumption that
massive stars age more quickly and die off sooner than less massive stars
is true (and from all evidence it seems to be true regardless of the actual
age of the universe). The same seems to be true for the bulge stars of
other neighboring galaxies such as the Andromeda Galaxy, one of its
satellites, and M33. The problem is that such stars should be old if the
collapsing cloud model of galactic origin is correct. Evolutionists
propose that collisions between galaxies have triggered star formation in
the halos at a later date than the formation of the galaxy itself. The
problem is, how many collisions can there be if all four of these galaxies
have undergone collisions at about the same time. Still, one can always
add more and more hypothesis to save any theory.
Speaking of Sagnac effect
Hitachi has developed an optical fiber gyro for automotive (yes, that's
right, automotive) navigational systems. The gyroscope, which works by
circulating light beams in opposite directions around a spool, detects rotation
of the car and thus provides an azimuth (angle from north) reading.
It's already been installed as an azimuth sensor in certain Toyota
vehicles.
