 Posted: Tue Jul 29, 2008 4:26 pm Post subject: Diamonds May Have Jump-started Life on Earth |
 |
|
| Quote: | One of the greatest mysteries in science is how life began. Now one group of researchers says diamonds may have been life's best friend.
Scientists have long theorized that life on Earth got going in a primordial soup of precursor chemicals. But nobody knows how these simple amino acids, known to be the building blocks of life, were assembled into complex polymers needed as a platform for genesis.
Diamonds are crystallized forms of carbon that predate the oldest known life on the planet. In lab experiments aimed to confirm work done more than three decades ago, researchers found that when treated with hydrogen, natural diamonds formed crystalline layers of water on the surface. Water is essential for life as we know it. Also, the tests found electrical conductivity that could have been key to forcing chemical reactions needed to generate the first life.
When primitive molecules landed a few billion years ago on the surface of these hydrogenated diamonds in the atmosphere of early Earth, the resulting reaction may have been sufficient enough to generate more complex organic molecules that eventually gave rise to life, the researchers say.
The research, by German scientists Andrei Sommer, Dan Zhu, and Hans-Joerg Fecht at the University of Ulm, is detailed in the Aug. 6 issue of the American Chemical Society's journal Crystal Growth & Design. Funding was provided by the Landesstiftung Baden-Wurttemberg Bionics Network.
Another theory, called panspermia, holds that life on Earth arrived from space, as organisms rained down inside tiny meteors or giant comets.
The new research does not conclusively determine how life began, but it lends support to one possible way.
"Hydrogenated diamond advances to the best of all possible origin-of-life platforms," the researchers contend. |

So, I wonder where those came from.

I'm told they (ultimately) came from nothing. I believe otherwise.

 Some people believe everything they read. Scientists are as clueless about how life started as infants are. They just look foolish when they try to play God because they change their minds all the time. One thing we can always count on from scientists is the fact that they'll keep changing their old theories and replace them with new ones with the adage; "We now know that what we once thought was true is not true."  And that will continue until the end of life on earth.

The only thing nothing can produce is, well....nothing!
Glad we're on the same page.

Rom 1:22 - 23 Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Glad we agree.

Ooh, needless exaggeration. Good show!

Define what you mean by "all the time," I'm honestly curious.

"All the time" means that we can always count on scientists changing their minds. Again, "We now know that what we once thought was true is not true" is a common phrase by scientists that will always be common. The reason is that if scientists had the truth, they would stop exploring. But they never stop exploring because they don't have the truth but instead are always in search of the truth. That's because they're looking in the wrong place for the truth; the human imagination. So they speculate on what they see and claim their speculations are the infallible truth...that is, until they change their minds again and realize they were wrong, as they always do.

Searching for truth is a good thing. It's honesty in action. I'm sorry that you lack the intellectual honesty to appreciate the pursuit of truth. |

One of the signs of mental health is being able to account for evidence which in some way rebuts something already accepted. Science is able to handle it, religion simply isn't.
