We recently talked about time travel and parallel universes on Dreamland with Fred Alan Wolf. Japanese scientists report that they think it will soon be possible to create new, “baby universes” inside their labs. What will happen to these universes over time is anybody’s guess, because, once they are created, there will no longer be any way to detect them. Would they eventually expand into whole and complete universes like our own? It’s possible, Which leads to the question, where did WE come from?

Scientists now know that the universe is not infinite and that space is curved in on itself in the shape of a dodecahedron. Interestingly enough, the ancient Greeks, including Plato, thought the universe was made up of this geometrical shape, and the artist Leonardo da Vinci, who was the recipient of much ancient knowledge, studied these shapes as well.

Scientists have assumed our universe is young, but now they’re saying it’s middle aged and will stop expanding and start collapsing fairly soon. Of course, “soon” in astronomical terms means billions of years in the future. Right now, a mysterious “dark energy” is pushing the universe apart, but when this force loses its power, the cosmos will collapse.

Karl Glazebrook and Ivan Baldry, of Johns Hopkins University, announced in January that they had averaged all colors from the light of 200,000 galaxies and concluded that if the human could see this color, it would be a pale green?the color of the universe.

They now say they reached the wrong conclusion due to flawed software. The effect of the software error was that the computer picked a nonstandard white and mixed it with the other colors to come up with green. When the error was corrected and replaced with a standard white index, ?It looks like beige,? Glazebrook says. ?I don?t know what else to call it. I would welcome suggestions.? In January, Baldry called the color ?cosmic spectrum green.?
