Comet Comments

Hosts: Doug Sharp and Rich Geer

According to evolutionists, when comets hit Earth billions of years ago, they pelted the planet too fast and too steep for them to have delivered fragile organic molecules, according to a new study.

Using advances in computer simulations, a University of Cambridge-led team of researchers ran scenarios of comet strikes, comet interactions with an atmosphere, and gravity's influence on comet movements through space to determine whether they could have brought the chemical ingredients for life to Earth.

Rather than look at a bunch of important molecules, the researchers focused on one in particular: hydrogen cyanide, or HCN. Made of one hydrogen, one carbon, and one nitrogen atom, it's a simple molecule commonly carried on comets. They found that the immense heat would have literally vaporized most of those molecules on impact, challenging a theory on the origins of life that has existed for about a century.

Even in the rare case that HCN survived a crash to Earth, it would not have come in large enough quantities, said Richard Anslow, lead author of the paper, which appears in the journal Scientific Reports.

"It would really have to be a one-in-a-million occurrence," said Anslow, a Cambridge astronomer, in a statement. "We can't rule out for certain that it happened that way. But it seems to be a really rare occurrence — at best, a one-off fluke."

This is another case where scientists discover experimentally that their own theory fails them despite their desperate desire to verify an evolutionary claim.

In addition, Doug and Rich discuss the claim that a meteorite discovered four years ago in the Sahara Desert is from Mars and is dated 4.1 billion years old. They used Rubidium-Strontium dating. Rubidium is a relatively rare element and is an alkali metal that forms ions soluble in water. Strontium is on the other hand quite abundant and forms ions that are stronger bonding and less soluble in water. The assumption is that all of the Strontium found in the sample came from radioactive Rubidium and that no differential leaching occurred. Given these assumptions, it is no surprise that a deep time date is the result.
