I was reading this
morning the comedy of modern cosmology.
One positive note; of late these cosmologists seem to be worming up to
the idea “Who coverest thyself with light as with a garment: who stretchest out
the heavens like a curtain:” – Psalm 104: 2
You see some of them think the Universe has a diameter of 156 billion
light years while all the lemmings agree the Universe is about 13.7 billion
light years old. Read for yourself from CNN.com
“"All the distance covered
by the light in the early universe gets increased by the expansion of the
universe," explains Neil Cornish, an astrophysicist at Montana State
University. "Think of it like compound interest."
Need a visual? Imagine the
universe just a million years after it was born, Cornish suggests. A batch of
light travels for a year, covering one light-year. "At that time, the
universe was about 1,000 times smaller than it is today," he said.
"Thus, that one light-year has now stretched to become 1,000
light-years."
All the pieces add up to 78
billion-light-years. The light has not traveled that far, but "the
starting point of a photon reaching us today after traveling for 13.7 billion
years is now 78 billion light-years away," Cornish said. That would be the
radius of the universe, and twice that -- 156 billion light-years -- is the
diameter. That's based on a view going 90 percent of the way back in time, so
it might be slightly larger.”
If you extrapolate this idea just
a bit more, then a 6,000 year old Universe is not hard to see. I am reminded of a problem I gave my high
school students when I was a math teacher.
Just for fun let’s say that the
13.7 billion year age is an accurate coordinate time age for the Universe and
that the 78 billion light year radius is equally as good and that it all
started at the big bang. What would the
proper time number look like? Well, the
velocity of the expansion after the big bang is generally agreed to be
preposterous or insane or some other such adjective by these folks ( LUDICROUS SPEED).
Ok, maybe not ludicrous speed. Let’s try an average rate of expansion of 0.9999999999999c
where c is the speed of light. According
to the accepted formula, ΔƮ = ΔT*SQRT(1 – v^2/c^2), for proper time ΔƮ, then due to
the observable phenomenon of time dilation proper time would be about 6,128 years. In relativity, proper time is the elapsed
time between two events as measured by a clock that passes through both events.
In other words, if we would have
lived through the events of the supposed big bang as they unfolded the current
physics tells us that it would have taken no more than a few thousand years
(proper time) for the Universe as we know it to have formed.
