The “Faint Young Sun” Paradox

The “Faint Young Sun” Paradox

Old earth scientists have an insurmountable contradiction on their hands; if the earth really is billions of years, as they claim, a much younger sun would have been too weak to warm the earth, making evolution impossible.

Scientists working in Australia uncovered fossil algae in rocks which old earth evolutionists claim to be evidence that life developed between 3.0 to 3.5 billion years ago. This, however, sets
up a paradox that scientists have been unable to resolve.


Here is the problem for secular scientists, there is substantial scientific evidence that the sun’s power comes from the fusion of hydrogen into helium in the sun’s core. The reason that this creates a giant problem for them is that the sun gets hotter as it gets older. As hydrogen fuses, it changes the composition of the sun’s core, gradually increasing the sun’s temperature. As a result, the earth would have been much colder in the long past. In fact, the earth would have been well below freezing if it existed 3 billion years ago, (when life supposedly evolved). The rate of nuclear fusion depends upon the temperature. As the sun’s core temperatures increase, the sun’s energy output would also increase, causing the sun to brighten over time. Calculations show that the sun would have brightened by between 25% and 70%. This means that if the sun existed 3.5 billion years ago it would have been fainter, warming the earth much less than it does today. At the time when life was supposed to be bubbling in the primordial soup, the soup would have been frozen.


Inside ExplosionAll scientists acknowledge that there is no evidence that the sun was once much fainter in the geologic record. Evolutionists call this problem the “faint young sun paradox”. Over the years old earth scientists have proposed several mechanisms (rescuing devices) to explain away this problem. The primary of these theories was that the earth’s atmosphere has changed significantly over the 3.5 billion years. More greenhouse gases early in earth’s history, they say, would have retained more heat. To investigate this possibility, authors writing for the magazine Science sampled quartz veins from the Dresser and Apex formations in Western Australia that were thought to be nearly 3.5 billion years old. These quartz veins were formed by hydrothermal activity and contain trapped gases and fluids locked in crystals. The study authors assumed the trapped gases represent the “ancient” atmospheric gas levels. However, the results were not what the scientists expected to find. Dr. Ray Burgess from the University of Manchester said,

“The amount of nitrogen in the [supposed ancient] atmosphere was too low to enhance the greenhouse effect of carbon dioxide sufficiently to warm the planet.”

(Translation: Oops, I guess we were wrong ). In fact, the study showed that the socalled ancient atmosphere contained slightly less than today’s levels of atmospheric nitrogen, making the “faint young sun paradox” even more perplexing. When you think about, it its silly to believe that a mechanism totally unrelated to the sun’s brightness could compensate for the sun’s changing emission so precisely for billions of years. But then again, many of the rescuing devices of secular science border on the absurd.


The bottom line is that science has no sensible answer for this so-called paradox. However, if you assume that the earth is thousands of years old (like it says in the Bible), and not billions of years old then there would be no need to solve this problem. Over thousands of years the sun’s temperature would have changed very little. Once again modern science confirms the Creation account in Genesis.
