Legendary author PMH Atwater tells how evolution is actually speeding up as the human species strives to create more and more intelligent children, who will be able to understand our situation on earth, and save the race. Then Linda Howe offers a stunner about the mystery of "dark matter," and what the invisible universe all around us may contain.
Newswise – A big part of the universe has been missing for 10 billionyears, since the time when the stars first formed, but nowscientists have solved the mystery. Where is it? It’sfloating in super-hot rivers of gas that are invisible tothe naked eye, surrounding galaxies like our own. And acompletely different kind of mystery matter?dark matter?mayhave put it there.

Two of the biggest mysteries in physics are: where is all the dark matter that scientists know is in the universe but can’t see??and are there extra dimensions beyond the 3 we can see? A team of scientists now think these mysteries may be connected. “For the most part, these two questions have been treated separately in the past, and for the first time we’re making a direct link,” says Konstantin Matchev. “We’re suggesting that the dark matter may be due to extra dimensions.”

Scientists know there are more than the 3 dimensions we experience (4, if you include time as one of them), but they don’t know what or where they are. “We have a number of hints from experiments and theoretical ideas that make us think they’re probably out there,” says Joseph Lykken of the Fermi National Accelerator Laboratory. Discovering these extra dimensions could tell us why the cosmos is expanding more rapidly than ever and what the mysterious dark force is that we can detect in the universe. And this all ties in with string theory.
