Dear Friends:

Re "Dark" matter

Is it really "dark" or is it that it appears that way to our
eyes? Inn
order to "see" it has to radiate some kind of influence (which
may be in
another level of the electro-magnetic range of vibrations) but to
our
eyesight is seems "dark."

However. The fact that it exists implies there are transparencies
and
opaque nesses all over the Universe of which we are gradually
becoming
aware.

In fact it is highly probable that there is a very fine balance
between
"light" and :darkness" that has existed for billions of years,
and which
forms the pivotal point of life and living in the entire
universe.

I was just reading that the "pure water" we get from mountain
springs,
etc. has been endlessly recycled for billions of years since it
was
first formed.

We need to ask ourselves how and why any energy is first
developed. Hen
does it "manifest?" when does it become quiet and "rests?" Are
manvantara and pralayas facts ?

These are theories under investigation, and they show how the
science
we know of today is developing into a philosophical and even a
metaphysical area.

If we study the SECRET DOCTRINE we find that this is discussed
there 125
years ago and the important root ideas are detailed for us to
consider.

We need not entirely believe the whole Universe operates or
responds
solely on our views and measurements of energy in our little
world.

There are many factors that could make for variances of
"life-forms" out
there.

Theosophy is never "dated."


Best wishes,


Dallas

Dark Energy Changes the Universe	02.27.04


Dark energy has the cosmoslogists scratching their heads.

Observations taken by NASA's Hubble Space Telescope and future
space
telescopes will be needed in order to determine the properties of
dark energy, which makes up about 70 percent of the universe.

Probing dark energy, the energy in empty space causing the
expanding
universe
to accelerate, calls for accurately measuring how that expansion
rate
is increasing with time.

Dark energy is thought to drive space
apart.


The diagram at right shows the changes in the rate of expansion
since the universe's birth 15 billion years ago. The more shallow
the
curve, the faster the rate of expansion. The curve changes
noticeably
about 7.5 billion years ago, when objects in the universe began
flying apart at a faster rate. Astronomers theorize that the
faster
expansion rate is due to a mysterious, dark force that is pulling
galaxies apart. Image courtesy of NASA/STScI/Ann Feild. Click on

Telescope
to hunt for supernovae (an energetic explosive event that occurs
at
the end of a star's lifetime), using their brightness,
astronomers
could measure if the universe was expanding faster or slower in
the
distant past. In its search, Hubble discovered 42 new supernovae,
including six that are among the most distant ever found. The
farthest supernovae show that the universe was decelerating long
ago,
but then "changed gears" and began to accelerate. Albert Einstein
coined the term "cosmological constant" to represent the
possibility
that even empty space has energy and couples to gravity. Like
other
astronomers of the time, he thought that the universe was static
and
so proposed there was a repulsive force from space that kept the
universe in balance.Einstein discarded his own findings in 1929,
when
Edwin Hubble found through his research that the universe was
expanding and not static. Today, new data from Hubble may well
prove
Einstein was on the right track. The pull of gravity and the push
of
dark energy have been trying to outmuscle each other since the
beginning of time. About seven billion years ago, dark energy got
the
upper hand because the universe had grown so large and matter
(the
source of gravity) had expanded and scattered.At left is an
illustration of the possible fates of the universe. Unstable dark
energy could cause a "big rip" (the universe expands violently,
then
the stars, planets and atoms come unglued) or a "big crunch" (the
universe implodes or compresses). Image courtesy of
NASA/STScI/Ann
Feild. Click on image for larger view.Cosmologists believe about
70
percent of the universe consists of dark energy, 25 percent is
dark
matter, and only four percent normal matter (the stuff that
stars,
planets and people are made of). Hubble observations suggest the
dark
energy may be Einstein's cosmological constant, an energy
percolating
out of the vacuum of the space between galaxies.The energy of the
universe is dominated by empty space emitting a repulsive form of
gravity that is pushing the universe apart. But what does all
this
mean to Earth? Even if Einstein's theory was correct, we won't
have
to be concerned about the "dark side" for about 30 billion years,
according to Hubble researchers.For further information, visit:
