Five ancient rocky planets discovered

A solar system dating back billions of years points to the likelihood that Earth-sized worlds are common.
The five rocky planets, which are located within our own galaxy, are too close to their parent star to support life but the importance of the discovery lies in the fact that they were formed several billion years ago when the Milky Way was still in its infancy.

Their existence points to the likelihood that Earth-sized worlds have been forming throughout most of the time that the universe has been around and should therefore be extremely common.
The planets were found thanks to data collected by the Kepler Space Telescope which has so far identified 1,103 worlds orbiting distant stars and over 4,000 additional planetary candidates.

"There are far-reaching implications for this discovery," said Tiago Campante of the University of Birmingham. "We now know that earth-sized planets have formed throughout most of the Universe’s 13.8 billion-year history, which could provide scope of the existence of ancient life."

i knpow about science i got a's in school. except when it came to dissecting the idea made me sick. or maybe it was the preserving fluid.

There is lots of evidence of that though Daniel, that's the difference that you have not picked up on. Religion has none. You should read a Universe from nothing, to understand that "nothing" is filled with stuff. LINK - What Is Nothing? Physicists Debate what is that stuff. i believe it was our souls and god. i believe god made the rules of the universe and then started the universe. here both the bible and big bang agree. first there was nothing and then there was light. then the light separated from the darkness. in science that is when the first stars were formed. but they both agree with ...

What is that stuff? It is a temporary change in the amount of energy in a point in space. No the Bible does not agree with that, you are just using lack of direct observation to slot God in. It is a trail to follow, not a ready made answer. First there was nothing, and then there was heat, not light, for the first 380,000 years or so, the universe was essentially too hot for light to shine. Not a lot of agreeing happening there to be honest. ok you are correct, but the light was a close second.

ok you are correct, but the light was a close second. LOL, I can live with that!

but, you can't see a simulaity of both ideas. http://www.kingjamesbibleonline.org/book.php?book=Genesis&chapter=1&verse= The Creation of Light Genesis 1 1 In the beginning God created the heaven and the earth. 2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. 3 And God said, Let there be light: and there was light. as i said earlier science has found that water is an important element in the formation of stars.

I don't think anyone has questioned your right to have an opinion ? i also have the right to voice my opinion. I think you will find that in the very first sentence you responded to, I was defending your right to have an opinion. Next time you respond with indignation to any of my posts, try reading them first please ! Nor did you ever answer my question of what you believed in before you had your encounter with god ? That was in the same post. I know it's a little thing, but you allways capitalize the first letter in a sentence !

This is the Timewarrior speaking: Prayer has no place in the public schools, just like facts have no place in organized religion. - Superintendent Chalmers Congress shall make no law respecting an establishment of religion - U.S constitution, first admendment. What many fail to comprehend in the whole Intelligent Design in public school debate is that the concept is both unprovable and quite frankly at risk of discriminating against most religions. Who is the Intelligent designer. . .is it god? Then which god? The Christian verison? The Jewish version? What about the beliefs of the Hindus? Or ... [More]

i also have the right to voice my opinion. Not trying to be a mod but you have the right to free speech as a citizen of the US but you do not have that right on this forum. You agreed to certain rules, when you joined UM, which specify that certain subjects are brought up in specific forums and that means you gave up your right to say anything you want, anywhere you want on UM when you clicked on yes. As Waspie said, this is the science section, not the spirituality section, so you should start a thread that addresses the place of God in the universe, with a link to this article, in the spirit...

i also have the right to voice my opinion. Yes, but as Merc pointed out, you do not have the right to divert the topic based on what you agreed to when you signed up here. This is the science forum, I couldn't care less about your faith, but it has no place here. Cheers, Badeskov
