Submission + - Universe's dark ages may not be invisible after all

StartsWithABang writes: The Universe had two periods where light was abundant, separated by the cosmic dark ages. The first came at the moment of the hot Big Bang, as the Universe was flooded with (among the matter, antimatter and everything else imaginable) a sea of high-energy photons, including a large amount of visible light. As the Universe expanded and cooled, eventually the cosmic microwave background was emitted, leaving behind the barely visible, cooling photons. It took between 50 and 100 million years for the first stars to turn on, so in between these two epochs of the Universe being flooded with light, we had the dark ages. Yet the dark ages may not be totally invisible, as the forbidden spin-flip-transition of hydrogen may illuminate this time period after all.

'i don't know if GMO food is "dangerous" or not....i don't think anyone here really does....but i do know one thing. only a population with WAY more food then it could possibly dream of needing could ever have this debate.' Look at the effects of GMOs on lab rats! I rest my case... GMOs are pure evil, designed to kills us as part of a eugenics agenda. Oh, and for profit and power too. Control the world's food supply and you control the world. I can't believe so many people on here are dumb enough to think Monsanto are doing this to grow more crops to feed starving people! (Just like Bono reckoned) I bet these people also believe Bill Gates' vaccines are for the good of the children... :rolleyes:

As much as I love the GNU/Linux philosophy, I would rather give someone Linux Mint (over Ubuntu) as it plays multimedia out of the box! I have converted many to Linux this way (sorry, GNU/Linux) and the other week installed Xubuntu on a work mate's old laptop over Windows XP and had it running like new again. How chuffed he was, he said it was like having a brand new laptop again!!!!!
