Galaxies are Billions of Light Years Away, so isn't the Universe Billions of Years Old?by Dr. Walt Brown

For a complementary article on this same subject, be sure to also read this article: Why Does the Universe Appear to be Expanding?
- Was space, along with light emitted by stars, rapidly stretched out soon after creation began? If so, energy would have been added to the universe and starlight during that stretching. Pages 334–338 show that the scientific evidence clearly favors this stretching explanation over the big bang theory, which also claims that space expanded rapidly. (Yet, the big bang theory says all this expansion energy, plus all the matter in the universe, was, at the beginning of time, inside a volume much smaller than a pinhead.
- Has starlight always traveled at its present speed—about 186,000 miles per second or, more precisely, 299,792.458 kilometers per second?
If either (a) space and its starlight were stretched out, or (b) the speed of light was much faster in the past, then distant stars should be visible in a young universe. Here we will address possibility (b) by examining the historical measurements of the speed of light.
Historical MeasurementsDuring the past 300 years, at least 164 separate measurements of the speed of light have been published. Sixteen different measurement techniques were used. Astronomer Barry Setterfield of Australia has studied these measurements, especially their precision and experimental errors.1 His results show that the speed of light has apparently decreased so rapidly that experimental error cannot explain it! In the seven instances where the same scientists remeasured the speed of light with the same equipment years later, a decrease was always reported. The decreases were often several times greater than the reported experimental errors. I have conducted other analyses that weight (or give significance to) each measurement according to its accuracy. Even after considering the wide range of accuracies, it is hard to see how one can claim, with any statistical rigor, that the speed of light has remained constant.2
M. E. J. Gheury de Bray, in 1927, was probably the first to propose a decreasing speed of light.3 He based his conclusion on measurements spanning 75 years. Later, he became more convinced and twice published his results in Nature,4 possibly the most prestigious scientific journal in the world. He emphasized, “If the velocity of light is constant, how is it that, invariably, new determinations give values which are lower than the last one obtained ... There are twenty-two coincidences in favour of a decrease of the velocity of light, while there is not a single one against it.”5 [emphasis in original]
Although the measured speed of light has decreased only about 1% during the past three centuries, the decrease is statistically significant, because measurement techniques can detect changes thousands of times smaller. While the older measurements have greater errors, the trend of the data is startling. The farther back one looks in time, the more rapidly the speed of light seems to have been decreasing. Various mathematical curves fit these three centuries of data. When some of those curves are projected back in time, the speed of light becomes so fast that light from distant galaxies conceivably could have reached Earth in several thousand years.
No scientific law requires the speed of light to be constant.6 Many simply assume that it is constant, and of course, changing old ways of thinking is sometimes difficult. Russian cosmologist, V. S. Troitskii, at the Radiophysical Research Institute in Gorky, is also questioning some old beliefs. He concluded, independently of Setterfield, that the speed of light was 10 billion times faster at time zero!7 Furthermore, he attributed the cosmic microwave background radiation and most redshifts to this rapidly decreasing speed of light. Setterfield reached the same conclusion concerning redshifts by a different method. If either Setterfield or Troitskii is correct, the big bang theory will fall (with a big bang).
Other cosmologists are proposing an enormous decay in the speed of light.8 Several of their theoretical problems with the big bang theory are solved if light once traveled millions of times faster.9
Atomic vs. Orbital TimeWhy would the speed of light decrease? T. C. Van Flandern, working at the U.S. Naval Observatory, showed that atomic clocks are probably slowing relative to orbital clocks.10 Orbital clocks are based on orbiting astronomical bodies, especially Earth’s one-year period about the Sun. Before 1967, one second of time was defined by international agreement as 1/31,556,925.9747 of the average time it takes Earth to orbit the Sun. On the other hand, atomic clocks are based on the vibrational period of the cesium-133 atom. In 1967, a second was redefined as 9,192,631,770 oscillations of the cesium-133 atom. Van Flandern showed that if atomic clocks are “correct,” the orbital speeds of Mercury, Venus, and Mars are increasing. Consequently, the gravitational “constant” should be changing. However, he noted that if orbital clocks are “correct,” then the gravitational constant is truly constant, but atomic vibrations and the speed of light are decreasing. The drift between the two types of clocks was only several parts per billion per year. But again, the precision of the measurements is so good that the discrepancy is probably real.
For the following four reasons, orbital clocks seem to be correct and atomic frequencies are probably slowing very slightly.
- If atomic clocks and Van Flandern’s study are correct, the gravitational “constant” should be changing. Other studies have not detected variations in the gravitational constant.
- If a planet’s orbital speed increased (and all other orbital parameters remained the same), the planet’s energy would increase. That would violate the law of conservation of mass-energy.
- If atomic time is slowing, then clocks based on the radioactive decay of atoms should also be slowing. Radiometric dating techniques would give ages that are too old. This would bring radiometric clocks more in line with most dating clocks. It would also explain why no primordial isotopes have half-lives of less than 50 million years. Such isotopes simply decayed away when radioactive decay rates were much greater.11
- If atomic frequencies are decreasing, then five “properties” of the atom, such as Planck’s constant, should also be changing. Statistical studies of past measurements show that four of the five “constants” are changing—and in the right direction.12
So, orbital clocks seem to be more accurate than the extremely precise atomic clocks.13
Many of us were skeptical of Setterfield’s initial claim, because the decrease in the speed-of-light measurements ceased in 1960. Large, one-time changes seldom occur in nature. The measurement techniques were precise enough to detect any decrease in the speed of light after 1960, if the trend of the prior three centuries had continued. Later, Setterfield realized that beginning in the 1960s, atomic clocks were used to measure the speed of light. If atomic frequencies are decreasing, then both the measured quantity (the speed of light) and the newly adopted measuring tool (atomic clocks) are changing at the same rate. Naturally, no relative change would be detected, and the speed of light would be constant in atomic time—but not orbital time.
MisconceptionsDoes the decrease in the speed of light conflict with the statement frequently attributed to Albert Einstein that the speed of light is constant? Not really. Einstein said that the speed of light was not altered by the velocity of the light’s source. Setterfield says that the speed of light decreases over time.
Einstein’s statement that the speed of light is independent of the velocity of the light source, is called Einstein’s Second Postulate. (Many have misinterpreted it to mean that “Einstein said the speed of light is constant over time.”) Einstein’s Second Postulate is surprising, but probably true. Wouldn’t we expect a ball thrown from a fast train in the forward direction to travel faster than one thrown in the opposite direction, at least to an observer on the ground? While that is true for a thrown ball, some experimental evidence indicates it is not true for light.14 Light, launched from a fast-moving train, will travel at the same speed in all directions. This strange property of light led to the more extensive theory of special relativity.15
Some people give another explanation for why we see distant stars in a young universe. They believe that God created a beam of light between Earth and each star. Of course, a creation would immediately produce completed things. Instantly, they would look much older than they really were. This is called “creation with the appearance of age.” The concept is sound. However, for starlight, this presents two difficulties:
- Bright, exploding stars are called “supernovas.” If starlight, seemingly from a supernova, had been created en route to Earth and did not originate at the surface of an exploding star, then what exploded? Only a relatively short beam would have been created near Earth. If the image of an explosion was created on that short beam of light, then the star never existed and the explosion never happened. One finds this hard to accept.
- Every hot gas radiates a unique set of precise colors, called its emission spectrum. The gaseous envelope around each star also emits specific colors that identify the chemical composition of the gas. Because all starlight has emission spectra, this strongly suggests that a star’s light originated at the star—not in cold, empty space. Each beam of starlight also carries other information, such as the star’s spin rate, magnetic field, surface temperature, and the chemical composition of the cold gases between the star and Earth. Of course, God could have created this beam of light with all this information in it. However, the real question is not “Could God have done it?” but “Did He?”
Therefore, starlight seems to have originated at stellar surfaces, not in empty space.
Surprising ObservationsStarlight from distant stars and galaxies is redshifted—meaning that their light is redder than one might expect. Although other interpretations are possible, most astronomers have interpreted redshifted light to be a wave effect, similar to that of the lower pitch of a train’s whistle when the train is going away from an observer. As the wave emitter (train or star) moves away from an observer, the waves are stretched, making them lower in pitch (for the train) or redder in color (for the star or galaxy). The greater a star’s or galaxy’s redshift, the faster it is supposedly moving away from us.
All atoms give off tiny bundles of energy (called quanta) of fixed amounts—and nothing in between. So, Setterfield believes that the “quantization of redshifts,” as many describe it, is an atomic effect, not a strange recessional-velocity effect. If space slowly absorbs energy from all emitted light, it would do so in fixed increments, which would redshift starlight, with the farthest star’s light red-shifting the most. Setterfield is working on a theory to tie this and the decay in the speed of light together. If he is correct, we should soon see the redshifts of a few distant galaxies suddenly decrease. This may explain why two distinct redshifts are seen in each of several well-studied galaxies;22 they are obviously not flying apart!
Another surprising observation is that most distant galaxies look remarkably similar to nearer galaxies. For example, galaxies are fully developed and show no signs of evolving. This puzzles astronomers.23 If the speed of light has decreased drastically, these distant, yet mature, galaxies no longer need explaining. Also, the light from a distant galaxy would have reached Earth not too long after the light from nearby galaxies. This may be why spiral galaxies, both near and far, have similar twists. [See Figure 170.]
The arms in these six representative spiral galaxies have about the same amount of twist. Their distances from Earth are shown in light-years. (One light-year, the distance light travels in one year, equals 5,879,000,000,000 miles.) For the light from all galaxies to arrive at Earth tonight, the more distant galaxies, which had to release their light long before the closer galaxies, did not have as much time to rotate and twist their arms. Therefore, farther galaxies should have less twist. Of course, if light traveled millions of times faster in the past, the farthest galaxies did not have to send their light long before the nearest galaxies. Spiral galaxies should have similar twists. This turns out to be the case.21 The galaxies are: A) M33 or NGC 598; B) M101 or NGC 5457; C) M51 or NGC 5194; D) NGC 4559; E) M88 or NGC 4501; and F) NGC 772. All distances are taken from R. Brent Tully, Nearby Galaxies Catalog (New York: Cambridge University Press, 1988).
A Critical TestIf the speed of light has decreased a millionfold, we should observe events in outer space in extreme slow motion. Here is why.
Imagine a time in the distant past when the speed of light was a million times faster than it is today. On a hypothetical planet, billions of light-years from Earth, a light started flashing toward Earth every second. Each flash then began a very long trip to Earth. Because the speed of light was a million times greater than it is today, those initial flashes were spaced a million times farther apart than they would have been at today’s slower speed of light.
Now, thousands of years later, imagine that throughout the universe, the speed of light has slowed to today’s speed. The first of those light flashes—strung out like beads sliding down a long string—are approaching Earth. The large distances separating adjacent flashes have remained constant during those thousands of years, so the moving flashes slowed in unison. Because the first flashes to strike Earth are spaced so far apart, they will strike Earth every million seconds. In other words, we are seeing past events on that planet (the flashing of a light) in slow motion. If the speed of light has been decreasing since the creation, then the farther out in space we look, the more extreme this slow motion becomes.
About half the stars in our galaxy are binary. That is, they and a companion star are in a tight orbit around their common center of mass. If there is a “slow-motion effect,” the apparent orbital periods of binary stars should tend to increase with increasing distance from Earth. If the speed of light has been decreasing, the Hubble Space Telescope may eventually find that binary stars at great distances have very long orbital periods, showing that we are observing them in slow motion.

- In two published experiments, the speed of light was exceeded by as much as a factor of 100! The first experiment involved radio signals which, of course, are a type of light. [See P. T. Pappas and Alexis Guy Obolensky, “Thirty Six Nanoseconds Faster Than Light,” Electronics and Wireless World, December 1988, pp. 1162–1165.] The second report referred to a theoretical derivation and a simple experiment that allowed electrical signals to greatly exceed the speed of light. This derivation follows directly from Maxwell’s equations. The special conditions involved extremely thin electrical conductors with very low capacitance and inductance. [See Harold W. Milnes, “Faster Than Light?” Radio-Electronics, Vol. 54, January 1983, pp. 55–58.]
- Another phenomenon allows light to slightly exceed its normal speed. [See Julian Brown, “Faster Than the Speed of Light,” New Scientist, 1 April 1995, pp. 26–29.

Two comments. First, each problem Barrow mentions is actually a reason for concluding the big bang theory is wrong. Second, no scientific law says that the speed of light is a constant. It has only been assumed to be such. In fact, today it is arbitrarily defined as a constant.
9. For example, “the horizon problem” recognizes that opposite extremes of the universe have the same temperature. Why should this be? The universe isn’t old enough for such vastly separated regions ever to have had contact with each other. Light doesn’t travel fast enough—at least not today.

11. Some who believe in an old universe have a different explanation. Those isotopes are extinct because so much time has passed. However, this explanation raises a counterbalancing question: How did those isotopes, and 97% of all elements, form? The standard answer is that these elements appeared during 13.7 billion years’ worth of supernova explosions. This is speculation, because no supporting evidence has been found. Besides, in our galaxy, we see the remnants of only 7,000 years’ worth of supernovas. [See “Supernova Remnants” on page 39.]

13. “Precision” should not be confused with “accuracy.” Atomic clocks are very precise, but not necessarily accurate. They keep very consistent time with each other, and each atomic clock can subdivide a second into 9 billion parts. This is remarkable precision. But what if this entire global network of atomic clocks is drifting—speeding up or slowing down? Precision, while impressive, is a necessary but not sufficient requirement for accuracy.

15. Another question concerns Einstein’s well-known formula, E=mc2, which gives the energy (E) released when a nuclear reaction annihilates a mass (m). If the speed of light (c) decreases, then one might think that either E must decrease or m must increase. Not necessarily.
- In the universe, time could flow according to either atomic time or orbital time. Under which standard would E=mc2 be a true statement? Mass-energy would be conserved under both; in other words, the energy or mass of an isolated system would not depend on how fast time passed. Obviously, E=mc2 would be true in atomic time where c is constant, but not in orbital time where c appears to decrease. Today, E=mc2 will be approximately correct even in orbital time.
- Nuclear reactions convert mass to energy. Unfortunately, the extremely small mass lost and large energy produced cannot be measured precisely enough to test whether E=mc2 is absolutely true in orbital time. Even if mass and energy were precisely measured, this formula has embedded in it an experimentally-derived, unit-conversion factor that requires a time measurement by some clock. Which type of clock should be used: an orbital clock or an atomic clock? Again, we can see that E=mc2 is “clock dependent.”
- If c has decreased (using the orbital time standard), neither length, electrical charge, nor temperature standards would change. Therefore, chemical and nuclear reactions would not change. However, the speed of chemical and nuclear reactions would change, because the vibrational frequencies of atoms and nuclei would change. Also, radioactive decay rates, which depend on the vibrational frequency of the nucleus, would decrease if c decreased.
