Re: Evolution for quacks.

For example, there are literally hundreds of data points which fit the Big Bang theory precisely, so we have confidence in the theory (e.g. nucleosynthesis of elements, red shifts of galaxies, microwave background radiation). It's a free country, so anyone can voice their aesthetic displeasure at the Big Bang theory, but not everyone can come up with a rival theory which explains these hundreds of data points! It's easy to criticize: it's much, much harder to come up with a better theory. Quote:
A singularity is a region of space-time in which gravitational forces are so strong that even general relativity, the well-proven gravitational theory of Einstein, and the best theory we have for describing the structure of the universe, breaks down there. A singularity marks a point where the curvature of space-time is infinite, or, in other words, it possesses zero volume and infinite density. General relativity demands that singularities arise under two circumstances. First, a singularity must form during the creation of a black hole. When a very massive star reaches the end of its life, its core, which was previously held up by the pressure of the nuclear fusion that was taking place, collapses and all the matter in the core gets crushed out of existence at the singularity. Second, general relativity shows that under certain reasonable assumptions, an expanding universe like ours must have begun as a singularity. However, it is known that by the end of the first second of time, the building blocks of matter had formed. By the end of the first three minutes, helium and other light nuclei (like deuterium) had formed but for a long time, temperatures remained too high for the formation of most atoms. At around one million years following the Big Bang, nuclei and electrons were at low enough temperatures to coalesce to form atoms. But the universe didn’t start to look like it does today until small perturbations in the matter distribution were able to condense to form the stars and galaxies we know today. Quote:
Tiny temperature fluctuations in the otherwise smooth cosmic background radiation represent the gravitational seeds in the early universe around which galaxies and galaxy clusters ultimately formed. Predicted by George Gamow and his collaborators in the 1940s and detected by Arno Penzias and Robert Wilson in the 1960s, the cosmic background radiation is the faint echo of the Big Bang. Following the explosive birth of our cosmos, the universe both expanded and cooled off rapidly. After roughly 300,000 years, its temperature had fallen to about 3000 kelvin (5000° Fahrenheit) and a big change was taking place. Before this time, conditions were too hot for atoms to form—protons and electrons each went their separate ways—and photons of light could travel only short distances before interacting with the free electrons. It was as if the universe existed in a thick fog that kept light from penetrating. But when the temperature reached 3000 kelvin, atomic nuclei finally captured electrons and formed stable atoms. Photons were then able to travel unimpeded—the fog lifted—and the universe became transparent to light. It’s that light we see as the background radiation, coming at us from all directions. However, in the 10 billion or more years since the Big Bang, the universe has expanded by a factor of a thousand, causing the temperature of the radiation to fall by the same amount. It now glows at just 3 kelvin (3° Celsius above absolute zero) in the microwave part of the electromagnetic spectrum, a faint reminder of our universe’s hot start. The background appears very smooth, varying by only one part in 100,000 across the sky. Quote:
The most famous of Einstein’s equations, E=mc2 says that energy (E) and mass (m) are equivalent. In other words, mass can be converted to energy and vice versa. The conversion factor is the speed of light (c) squared, an enormous number when you consider that the speed of light itself is a whopping 186,000 miles per second. This means that a small amount of matter can be transformed into a huge amount of energy. That’s the secret of stars, where high temperatures and densities permit lighter atoms to fuse into heavier ones. Each heavy atom weighs less than the combined weight of the lighter atoms that formed it, and that difference in mass becomes the energy that keeps stars shining. The process also works in reverse: Energy can be transformed into mass. Cosmologists think that’s how the matter in the universe arose—in the first second following the Big Bang, photons of incredible energy collided with one another, creating pairs of particles and antiparticles. |

pfffftt

Evolutionary theory doesn't predict the existence of fishmen, apemen, birddog, snaketree, beastasses, etc... Come back when you actually understand the theory enough to offer at least semi-educated commentary on the subject. |

I am so lonely. How long has it been scince we had a creationist that sticks around for more that five posts? Micheal144 was promising, but he's gone too.
Dog, I miss vanderzyden. |

awwwww, don't worry, didymus! *big hug* i'm sure a nice creationist who won't run off will eventually come around to play! it's not like we're hoarding the sand box.......

Sorry guys, but if you ask me "thebeast" was only providing a satirical chariciture of the average creationist, and a bloody funny one at that if you want my opinion. Read it from the perspective that it's an evolutionist harpooning the creationist stance, and you may just get the joke as I see it..... |
