Rutgers scientists debunk a life-origin theory

For the first time, there are solid data to refute a popular theory that life came to the Earth aboard a comet, Rutgers researchers said Monday.

Deteriorated DNA from microbes, frozen for millions of years in the Antarctic ice, shows that organisms could not have survived the bombardment of cosmic radiation during deep space travel from outside the solar system, said Paul Falkowski, a Rutgers biologist and oceanographer.

"It's almost an impossibility for comets to seed other planets with life after they've been in space for millions of years," Falkowski said.

That's because genetic material is severely damaged or destroyed by exposure to so-called "cosmic radiation flux," he said. Falkowski is co-director of the two-year study of frozen glacial microbes, conducted in conjunction with Boston University, and published in the Proceedings of the National

This is from comet to planet, I'm still holding out that you can cross-contaminate from planet to planet. Still an interesting theory

Important research.

This theory was promoted about a century ago by Arrhenius. Although it obviates stewing about the origin of life on earth, it really begs the question as it brings about the question, How did life originate on planet X

I wonder how much money and years of education it took, to realize that life can't nakedly withstand deep space?

Yet, that won't stop those who would debunk revealed truth.

“It’s almost an impossibility for comets to seed other planets with life after they’ve been in space for millions of years,” Falkowski said.

but perhaps it is possible for comets to seed other planets with life after they’ve been in space for thousands of years.

"How did life originate on planet X"

That's any easy one.

In the future, super-intelligent androids from our planet will build a time machine so they can go back and seed the original planets with living matter.

If so, there should be significant evidence on Mars and Venus that would support that theory.

It just breaks my heart that we haven't sent people to Mars yet. It's so silly that we waste so many resources, and we don't do something worthwhile like exploring the solar system. We should have condos on Neptune by now. But I suppose it's just as well we spend billions for illegal immigrant healthcare.

Life is amazingly tenacious so it’s really hard to say that it can’t happen.

Thought so.

Oh sure, there are all sorts of bacterial spores that just hang on for dear life in the harshest of environments. Who knows. I wouldn't put it past them to survive in space.

In my opinion, duration of the exposure to radiation would be the biggest hurdle. A few decades is one thing but billions of years is another thing altogether.

Springtime is blooming on Neptune! This might sound like an oxymoron because Neptune is the farthest and coldest of the major planets. But NASA Hubble Space Telescope observations are revealing an increase in Neptune's brightness in the southern hemisphere, which is considered a harbinger of seasonal change, say astronomers.

Observations of Neptune made over six years by a group of scientists from the University of Wisconsin-Madison and NASA's Jet Propulsion Laboratory (JPL) show a distinct increase in the amount and brightness of the banded cloud features located mostly in the planet's southern hemisphere.

"Neptune's cloud bands have been getting wider and brighter," says Lawrence A. Sromovsky, a senior scientist at University of Wisconsin- Madison's Space Science and Engineering Center and a leading authority on Neptune's atmosphere. "This change seems to be a response to seasonal variations in sunlight, like the seasonal changes we see on Earth."

The findings are reported in the current issue (May, 2003) of Icarus, a leading planetary science journal.

Neptune, the eighth planet from the Sun, is known for its weird and violent weather. It has massive storm systems and ferocious winds that sometimes gust to 900 miles per hour, but the new Hubble observations are the first to suggest that the planet undergoes a change of seasons.
Based on the weather, housing should be relatively inexpensive.

How did life originate on planet X

Well, that life was seeded from planet W, whose life was seeded from planet V, and so it goes....

If they keep pushing it back far enough, they can maybe ignore that life cannot spontaneously arise from non-living matter (spontaneous generation) and can avoid that complicating little factor.

"It's almost an impossibility "

Good news. Then all you need is time and it will happen.

I didn't know the Bible said anything about the deterioration rate of DNA in ice.

“I didn’t know the Bible said anything about the deterioration rate of DNA in ice.” ..... If it can not be found in there, it may appear in a revised scripture 100 yrs from now.
