If the
earth is only 6,000 years old, how do we see stars billions of light years
away?
Answer:
This is
one of the most commonly asked questions and deserves a good answer. Below is
first a short answer then a more thorough answer. There are three things we
need to consider when answering the starlight question.
1. Scientists cannot
measure distances beyond 100 light years accurately.
2. No one knows what light
is or that it always travels the same speed throughout all time, space and
matter.
3. The creation was
finished or mature when God made it. Adam was full-grown, the trees had fruit
on them, the starlight was visible, etc.
Let
me elaborate on these 3 points.
First, no one can measure star
distance accurately. The farthest accurate distance man can measure is 20 light
years (some textbooks say up to 100), not several billion light years. Man
measures star distances using parallax trigonometry. By choosing two measurable
observation points and making an imaginary triangle to a third point, and using
simple trigonometry, man calculates the distance to the third point. The most
distant observation points available are the positions of the earth in solar
orbit six months apart, say June and December. This would be a base for our
imaginary triangle of 186,000,000 miles or 16 light minutes. There are 525,948
minutes in a year. Even if the nearest star were only one light year away (and
it isn’t), the angle at the third point measures .017 degrees. In simpler
terms, a triangle like this would be the same angle two surveyors would see if
they were standing sixteen inches apart and focusing on a third point 8.24
miles away. If they stayed 16 inches apart and focused on a dot 824 miles away,
they would have the same angle as an astronomer measuring a point 100 light
years away. A point 5 million light years away is impossible to figure with
trigonometry. The stars may be that far away but modern man has no way of
measuring those great distances. No one can state definitively the distance to
the stars. The stars may indeed be billions of light years away, but man cannot
measure those distances.
Several other methods such as
luminosity and red shift are employed to try to guess at greater distances but
all such methods have serious problems and assumptions involved. For a more
complex and slightly different answer to the star light question from a
Christian perspective, see the book Starlight and Time by Russell Humphry
available from www.icr.org.
Second, the speed of light may
not be a constant. It does vary in different media (hence the rainbow effect of
light going through a prism) and may vary in different places in space. The
entire idea behind the black hole theory is that light can be attracted by
gravity and be unable to escape the great pull of these imaginary black holes.
No one knows what light is let alone that its velocity has been the same all
through time and space. Since atomic clocks use the wavelength of the Cesium
133 atom as a standard of time, if the speed of light is decaying, the clock
would be changing at the same rate and therefore not be noticed.
On February 18, 1999, Houston
Chronicle ran an article on page 10A about a Danish Physicist, Dr. Hau working
at Harvard, being able to slow down light by cooling it. They cool it to
fifty-billionths of a degree above absolute zero -459.67. The light was slowed
down to 38 MPH!
In Dallas Morning News on
2-28-2000 the article says they have now slowed it to 1 MPH! See also New
Scientist, July 24, 1999 pp. 28-32 and Science News, June 9, 1984, p.359 for
more on gravity effecting light.
"Eureka! Scientists break
speed of light", Jonathan Leake, Science Editor, Sunday Times [UK] June 4,
2000.
UNITED STATES SCIENTISTS claim they have broken the ultimate speed barrier: the
speed of light. In research carried out in the United States, particle
physicists have shown that light pulses can be accelerated to up to 300 times
their normal velocity of 186,000 miles per second.
The work was carried out by Dr Lijun Wang, of the NEC research institute in
Princeton, who transmitted a pulse of light towards a chamber filled with
specially treated cesium gas. See also: New York Times May, 30, 2000 www.nytimes.com
Scientists Bring Light To Full
Stop, Hold It, Then Send It On Its Way

Researchers say they have slowed
light to a dead stop, stored it and then released it as if it were an ordinary
material particle.
The achievement is a landmark feat that, by reining in nature's swiftest and
most ethereal form of energy for the first time, could help realize what are
now theoretical concepts for vastly increasing the speed of computers and the
security of communications.
Two independent teams of physicists have achieved the result, one led by Dr.
Lene Vestergaard Hau of Harvard University and the Rowland Institute for
Science in Cambridge, Mass., and the other by Dr. Ronald L. Walsworth and Dr.
Mikhail D. Lukin of the Harvard-Smithsonian Center for Astrophysics, also in
Cambridge.
During the last 300 years, at
least 164 separate measurements of the speed of light have been published.
Sixteen different measurement techniques were used.

"A shocking possibility is
that the speed of light might change in time during the life of the
universe."

The atomic clock. In 1956,
following several years of work, two astronomers at the U.S. Naval Observatory
(USNO) and two astronomers at the National Physical Laboratory (Teddington,
England) determined the relationship between the frequency of the Cesium atom
(the standard of time) and the rotation of the Earth at a particular epoch. As
a result, they defined the second of atomic time as the length of time required
for 9 192 631 770 cycles of the Cesium atom at zero magnetic field. The second
thus defined was equivalent to the second defined by the fraction 1 / 31 556
925.9747 of the year 1900.
Third, the creation account
states that God made light before He made the sun, moon, or stars. The rest of
creation was mature, so starlight was probably mature at creation as well. I
would ask the question, How old was Adam when God made him? Obviously he was
zero years old. But how old did he look? He was a full-grown man. The trees
were full-grown with fruit on them the first day they were made. The creation
had to be that way; it would not work otherwise. Stars and their light were
made at the same time. The God that I worship is not limited by anything
involving time, space or matter.
Finally, I would also like to
point out that the evolutionists have no answer to the basic questions like;
Where did the original matter space and energy come from for the stars? I
suspect God built the universe so we would say "Wow!" When we see the
stars we should be reminded of the glory of God not evolution. See Psalms 8.
