Some 2.4 billion years ago when the Milky Way started upping its star production, cosmic rays--high-speed atomic particles--started pouring onto our planet, causing instability within the living. Populations of bacteria and algae repeatedly soared and crashed in the oceans.
The researchers counted the amount of carbon-13 within sedimentary rocks, the most common rocks exposed on the Earth's surface. When algae and bacteria were growing in the oceans, they took in carbon-12, so the ocean had an abundance of carbon-13.
Many sea creatures use carbon-13 to make their shells. If there is a lot of carbon-13 stored in rocks, it means life, the origin of which is still unknown, was booming. Therefore, variations in carbon-13 are a good indicator of the productivity of life on Earth.
The researchers found that the biggest fluctuation in productivity coincided with star formation, which had an affect on Earth's climate and therefore on the productivity of life on our planet.
According to one theory, when a star explodes far away in the Milky Way, cosmic rays penetrate through the Earth's atmosphere and produce ions and free electrons. The released electrons act as catalysts and accelerate the formation of small clusters of sulfuric acid and water molecules, the building blocks of clouds. Therefore, cosmic rays increase cloud cover on Earth, reflecting sunlight and keeping the planet relatively cool.
Although cold and icy times are generally considered unfriendly to life, the data reveals that biological productivity kept oscillating between very high and very low. The reason, the researchers suggest, is that stronger winds during icy epochs stirred the oceans and improved the supply of nutrients in the surface waters.
"The odds are 10,000-to-1 against this unexpected link between cosmic rays and the variable state of the biosphere being just a coincidence, and it offers a new perspective on the connection between the evolution of the Milky Way and the entire history of life over the last 4 billion years," said study author Henrik Svensmark of the Danish National Space Center.
The study was detailed in a recent issue of the journal Astronomische Nachrichten.

To those who have difficulty understanding the English language, the word 'how' is a question.
To make it even easier for you, "How about this?" is a fairly obvious question to the educated. Now, do you finally get it or are you still struggling with the basics.
Which part of "How about this?" do you not understand?

Hey r u trying to prove that GOD dosen't exist or what???
Well I say, how come u know this all....
its ur brain which helps u understand the theory, BUT u r still unable to understand that what was the reason behind all this happening???
Why all this happened???
Who forced this to happen??
WHo planned this to happen????
& I think what a great planner HE is !
& How great is it that HE made all that understandable for us......
GOD made every thing very sensibly & made it all linked to each other, so that this HUMAN MIND can understand more easily........
BUT Alaas!!
when the human understands it he just denies the creator of everything....
I think Scientists are trying to create a new religion or something
They have not understood much of ourselves......
But they try to prove many things which has no logic....
NO NO NO!!!
Actually the scientists are not wrong.....
They are just doing their work....
It is just non believers who take unauthetic & incomplete theories as their basics & try to spread it without proofs
How griefy this moment is!

Yeah, so what. How old are you in elephant years. We have no concept of what a Day is for God.
The big thing is creation. No one has yet to prove where the mass of the Universe has come from. No one has yet to prove that ramdomly things can gather and explode.
All you're document is a factor of Genesis.
Get to the heart of the matter. Prove a monkey can shake a box of parts from Radio Shack for a billion years and produce a fully functioning Xbox without a solidering iron and schematic.

According to scientists and numerologists the chance that life should exist on earth is one in one billion.

For the sake of education. Islam stands with scientific proof and evidence. if you have the patience to study the unknown then proof to me that this video is wrong.

Great, now who started the whole process? Who made all the stuff that formed the galaxy and the cosmic rays? Just because you proved the method by which it was done doesn't mean you've disproved the existance of the one(s) who set it motion.

thats a well thought out question, and just goes to show that science, and not religion, is winning the argument about whee life actually comes from. And, if I may say so, I'm a Christain, but I can stand up for science when its argument is good (Which it tends to be anyway). Religion is just organised proaganda designed to scare us into beliveing in the afterlife, whereas, science proves that life has eveolved and will continue to do so!

That's really interesting.
Haha, they won't even be able to get past the first sentence. 2.4 billion years ago? So much for that "the universe is 6,000 years old" theory. :-P
