A meteorite that hit the town of Murchison, Australia, hasn't quit giving up its secrets.
The Murchison meteorite is one of the most studied space rocks because many pieces were recovered after it was seen breaking up as it fell through the atmosphere in 1969. Approximately 100 kg of the carbonaceous chondrite was recovered.
Carbonaceous chondrites are extremely important to scientists as they were formed from material that existed in the solar system's planet-forming disk of gas and dust. They are, quite literally, time capsules holding onto a 4 billion year old record of the birth of our solar system.
In this case, the Murchison meteorite has given us another clue as to the abundance of organic chemicals that existed before the Earth had formed. In fact, this particular meteorite may have originated from material older than our sun.
"We are really excited. When I first studied it and saw the complexity I was so amazed," said Dr Phillipe Schmitt-Kopplin, of the Institute for Ecological Chemistry in Neuherberg, Germany.
"Meteorites are like some kind of fossil. When you try to understand them you are looking back in time."
This new research made use of high resolution spectroscopic tools to identify the various compounds inside. Although this meteorite has provided scientists with vast amounts of information about specific carbon-based organics before, this was the first non-targeted study. In other words, the researchers weren't tracking down just one type of chemical, they did a broad analysis for all the chemicals it might contain.
And what they found came as a shock, it appears that the primordial solar system probably had a higher chemical diversity than present-day Earth.
In this study, 14,000 specific compounds including 70 amino acids were identified. But this number appears to be the tip of the iceberg; the meteorite probably contains millions of different organic compounds. More detailed analysis will now be carried out.
But why is this important? To understand the diversity of organic chemicals that were floating around a primordial solar system will help us understand how life may have appeared on Earth. This particular chunk of carbonaceous chondrite drifted through the gas and dust of the early solar system, collecting all the basic organic chemistry from around that time, does that mean diverse organic chemistry is the "norm" for proto-planetary star systems?
These organic compounds are known to exist on comets, asteroids and other planetary bodies, so what makes Earth the hothouse of life when everywhere else seems to be lifeless?
If organic chemistry is ubiquitous, perhaps planning to "seed" young star systems with Earth-based life isn't such a good idea. The conditions for life may not be that rare after all.
This is interesting if confirmed.
But, just because you have a bunch of organic chemicals doesn’t mean that a planet covered with it would produce life.
You still need: RNA, DNA and cell protein structure to permit amino acid chains to link in a rather complex sequences.
No one has any idea how the “primordial soup” — if it existed on earth — might spring to life.
The conditions for life may not be that rare after all.
The earth is only ~8000 miles in diameter. The Milky Way alone is around 100,000 light years across, and is only one of ~3000 visible galaxies and an estimated 500 billion galaxies in the universe. It doesn’t seem surprising to me that there would be organic matter elsewhere in all of that. Incidentally, for those who say that they don’t believe there is a reason for all of this, and say they don’t believe in God, how can you truly believe that all of the vastness of the universe exists for no reason?
I'll be happy to recommend a book to you that explains it in fairly simple terms.
Well, when life has been found elsewhere, please ping us.
I just wonder when one molecule decided that splitting into two parts was boring and stopped and then noticed that cute guy molecule over there ....
OK, please recommend a book or article on that. I am quite interested.
Seems to me that there are guesses (hardly feasible) about how biochemistry evolved, but no coherent theory that might permit experimental evidence.
Ha ha ha Comic book HA ha evolution is just like global warm and the easter bunny. It’s all a crock.
I want to know what formed the dust and gas in the total emptiness of space. The material that formed the planets had to come from somewhere but no scientist covers that, they kind of skip over it as if we are to just except the fact that 10s of millions, or trillions or more, of tons of dust, gas and other debris was just floating around in space(which, BTW, seems endless)with no apparent beginning. so, if someone can tell me where that material came from, and do it convincingly, I would be grateful.
Ha. You sound like a blond cheerleader.
Energy. Before matter, time, and space...there was pure energy.
It's just a matter of where and when.
Or is it?
I don't think that anyone agrees that all matter and energy collapsed into a single spot. That is the steady state theory which I think has been shown to have some problems with the math.
It seems that the universe began as a pea sized singularity in which all matter, space and time was fused into one thing. As mind boggling as it may seem, there was no space around this pea sized ball because space and time only came into being as product of the explosion.
It just popped into existence. I guess that this kind of popping occurs on the sub atomic level all of the time.
Theists believe in a Creator who is outside of space and time and created the ball and caused it to explode. The big bang theory seems eerily like Geneses chapter one and the doctrine of Creation ex nilio (out of nothing).
However, as you might expect, there are physicists who try to come up with other explanations to deny what I think is the obvious answer (God did it). For them, the universe just popped into existence for no reason.
I think that is what the Disclosure Project is by this Dr Steven Brewer that the Government is keeping the secret of Alternative Energy by Alien life
The Disclosure Project is a nonprofit research project working to fully disclose the facts about UFOs, extraterrestrial intelligence, and classified advanced energy and propulsion systems. We have over 400 government, military, and intelligence community witnesses testifying to their direct, personal, first hand experience with UFOs, ETs, ET technology, and the cover-up that keeps this information secret.

I agree. No way would God create all this and only produce life here.
So, what do they do? They now are speculating(and have been for a while)that life came here on a meteor, asteroid, comet or whatever as if that explains it, totally ignoring the question of HOW that life came into being before it came here on some celestial body.
Many things remain unexplained, but instead of owning up to that and admitting it the scientists make up sh**, just like the global warming crowd.
People are saying the scientists that embraced global warming have disgraced science, but science has always had its liars and fabricators, making stuff up to prove a theory. Pure energy my a**.
You didn’t explain what I asked. Where did the material that exploded come from, and if there was no space what was there? You can’t have an explosion that creates matter, you can only scatter it with the explosion, and sometimes you turn matter into energy when it explodes, such as in a nuclear explosion. I would imagine the “big bang”(which I don’t subscribe to, BTW)would have many orders of magnitude above any nuke explosion we have ever witnessed. Nope, your little rambling comment explains nothing. Nothing I have ever read answers the question: Where did the original matter come from?
Einstein says matter and energy are interchangeable. Modern science says time and space are BOTH also intergangeable with energy.
Therefore, the theory is that energy existed first, and was later converted into matter. Some was converted into space and some into time also.
I don’t understand that part about time and space. But I can see the idea that matter is energy. Protons neutrons, and electrons are apparently made out of pure energy. And all matter is made of these things.
You have to take things by steps. The first step was taken by Einstein, who conceived of space-time. Lucretius makes a comment prescient of this, "Time also exists not of itself, but from things themselves is derived the sense of what has been done in the past". Remarkable.
With General Relativity, Einstein established what Wheeler calls Geometrodynamics, that is a physics OF space-time, rather than a physics that transpires IN a rigid framework of space-time. But the idea of an evolving or changing space-time begs the question of time. It seems to require a "time out of time". This is thinking at the limit of what it is possible to conceive.
A very old theology explains life on earth fairly well I think and would encompass this meteorites composition.
“Where conditions are favorable for matter life emerges, where favorable for life, intelligence emerges, where favorable for intelligence, consciousness emerges.”
In the only example we have this has been bourne out.
There it is, proof positive we came from a bunch of rocks. Well, maybe the liberals did.
I think it would be fair to say that they have lots of ideas; just no definitive evidence the confirm or disconfirm any of them.
Just pointing out the obvious ....
I am more likely to believe God created it all than I am to believe that matter just suddenly formed from nothing, not only that we are to believe that nothing(space)formed from nothing.
A good look around the Solar System would show the conditions are extremely rare. And by any objective measure, life is rare on Earth, but not as rare as other places.
It depends on what your definition of life is.
I believe just recently they found life at underwater volcanoes and are quite shocked that organisms could exist in a toxic enviroment..
I guess if you are looking at planets for brights light or freeways,people walking around etc you might be find nothing at all and conclude no life exists.
Galaxies exist that are Gazillions of years older than Earth,i ain’t a gambling man but somewhere a form of life exists..
No, we can’t rule out life elsewhere. And I think as far as biological life is concerned we can conclude life is rare. You can take insects, microorganisms around vents and elsewhere, but life is rare even here on Earth. What objective measure would you like to use, mass, volume, etc? The proportion of life is super small.
Proponents of the big bang say that it all began with a singularity, which isn't an object but a horizon.
When the temperature is a billion billion billion degrees, all four fundamental forces are melted down into one substance. When it explodes and cools, time-space geometry, mater and chemical compounds emerge.
Seems like the physicists have mathematical formula and other good evidence for all of this and it jives with basic theology.
But, you say that you don't believe in the big bang.
Why do you doubt it I wonder. So, you are a creationist?
