butt, you were not able to add one centimeter of curvature...you do not even understand or know, according to your own declaration, the current situation in cosmology...let me refresh your memory...
Here is a short version of the Faint Young Sun Paradox (see, guynicebutt, when you talk to me, you have a chance to learn the best arguments, to gain a much better understanding)...
Supposedly the Sun has been a main-sequence star since its formation about 4.6 billion years ago. This time represents about half the assumed ten-billion-year main-sequence lifetime of the Sun, so the Sun should have used about half its energy store. This means that about half the hydrogen in the core of the Sun has been used up and replaced by helium. This change in chemical composition changes the structure of the core. The overall structure of the Sun would have to change as well, so that today, the Sun should be nearly 40% brighter than it was 4.6 billion years ago.
This obviously has consequences for the temperatures of the planets. It is generally believed that even small fluctuations in the Sun's luminosity would have devastating consequences on Earth's climate. A 40% change in solar luminosity should have produced dramatic climatic changes.
According to evolution, about four billion years ago when life supposedly first arose on Earth, the temperature had to have been close to what the temperature is today. But if that were the case, the subsequent increase in the Sun's luminosity would have made Earth far too hot for life today. One could naively suggest that Earth began cooler than it is today and has been slowly warming with time. But this is not an option because geologists note that Earth's rock record insists that Earth's average temperature has not varied much over the past four billion years, and biologists require a nearly constant average temperature for the development and evolution of life. This problem is called the early faint Sun paradox.
Evolution proposes that the early atmosphere contained a greater amount of greenhouse gases (such as methane) than today. This would have produced average temperatures close to those today, even with a much fainter Sun. As the Sun gradually increased in luminosity, Earth's atmosphere is supposed to have evolved along with it, so that the amount of greenhouse gases have slowly decreased to compensate for the increasing solar luminosity.
The precise tuning of this alleged co-evolution is nothing short of miraculous. The mechanism driving this would have to be a complex system of negative feedbacks working very gradually, though it is not at all clear how such feedbacks could occur. At any point, a slight positive feedback would have completely disrupted the system, with catastrophic consequences similar to those of Venus or Mars. For instance, the current makeup of Earth's atmosphere is in a non-equilibrium state that is maintained by the widespread diversity of life. There is no evolutionary imperative that this be the case: it is just the way it is. Thus the incredibly unlikely origin and evolution of life had to be accompanied by the evolution of Earth's atmosphere in concert with the Sun.
The implausibility of such a process has caused Lovelock to propose his Gaia hypothesis. According to this, the biosphere (consisting of Earth's oceans, atmosphere, crust, and all living things) constitutes a sort of super organism that has evolved. Life has developed in such a way that the atmosphere has been altered to protect it in the face of increasing solar luminosity. Lovelock's hypothesis has not been generally accepted, largely because of the spiritual implications. Indeed, it does seem to lead to a mystical sort of view.
If billions of years were true, the sun would have been much fainter in the past. However, there is no evidence that the sun was fainter at any time in the earth's history. Astronomers call this the faint young sun paradox.
Evolutionists and long-agers believe that life appeared on the earth about 3.8 billion years ago. But if that timescale were true, the sun would be 25% brighter today than it was back then. This implies that the earth would have been frozen at an average temperature of -3 C. However, most paleontologists believe that, if anything, the earth was warmer in the past. The only way around this is to make arbitrary and unrealistic assumptions of a far greater greenhouse effect at that time than exists today, with about 1,000 times more CO2 in the atmosphere than there is today.
The physical principles that cause the early faint Sun paradox are well established, so astrophysicists are confident that the effect is real. Consequently, evolutionists have a choice of two explanations as to how Earth has maintained nearly constant temperature in spite of a steadily increasing influx of energy. In the first alternative, one can believe that through undirected change, the atmosphere has evolved to counteract heating. At best this means that the atmosphere has evolved through a series of states of unstable equilibrium or even non-equilibrium. Individual living organisms do something akin to this, driven by complex instructions encoded into DNA. Death is a process in which the complex chemical reactions of life ceases and cells rapidly approach chemical equilibrium. Short of some guiding intelligence or design, a similar process for the atmosphere seems incredibly improbable. Any sort of symbioses or true feedback with the Sun is entirely out of the question. On the other hand, one can believe that some sort of life force has directed the atmosphere's evolution through this ordeal. Most find the teleological or spiritual implications of this unpalatable, though there is a trend in this direction in physics.
A much higher concentration of carbon dioxide in Earth's atmosphere has been suggested to maintain a proper temperature. This is an inferrence supported by no geological evidence whatsoever. Studies of iron carbonates by Rye et al. conclusively show that Earth had at most 20 percent the required amount of CO2. We have evidence that Mars also had temperatures suitable for liquid in its distant past. It is unlikely that CO2 would custom-heat both planets.
http://www.creationscience.com/onlinebook/AstroPhysicalSciences10.htmlConditions on the very early earth that permit the appearance and early evolution of life seem to be achievable without invoking too many improbabilities. As the sun then became hotter, however, we have a problem; if the greenhouse atmosphere is maintained for too long, as the sun brightens, a runaway greenhouse effect may result from positive feedback, creating a Venus-like situation and rendering the earth uninhabitable. A compensating negative feedback is required.
Some geochemical feedback may be possible, but it appears unlikely to be sufficient. Living organisms, too, started converting carbon dioxide into oxygen and organic matter, substantially decreasing the greenhouse effect as soon as photosynthesis got going. There is, however, no obvious reason for this process to keep exactly in step with the sun's increasing luminosity. It may be that we have simply been lucky, but as an explanation that is not entirely satisfactory. If the tuning did need to be very precise, Faulkner would have a point in calling it 'miraculous'.
As a result of a fainter Sun, the temperature on ancient Earth should have been some 25 C lower than today. Such a low temperature should have kept large parts of Earth frozen until about one to two billion years ago. The case for Mars is even more extreme due to its greater distance from the Sun. Yet there is compelling geologic evidence suggesting that liquid water was abundant on both planets three to four billion years ago.
Earth's oldest rocks, which are found in northern Canada and in the southwestern part of Greenland, date back nearly four billion years to the early Archean eon. Within these ancient rock samples are rounded 'pebbles' that appear to be sedimentary, laid down in a liquid-water environment. Rocks as old as 3.2 billion years exhibit mud cracks, ripple marks, and microfossil algae. All of these pieces of evidence indicate that early Earth must have had an abundant supply of liquid water in the form of lakes or oceans.
This apparent contradiction, between the icehouse that one would expect based upon stellar evolution models and the geologic evidence for copious amounts of liquid water, has become known as the 'faint young sun paradox.'
