An experiment with implications almost beyond imaginationhas confirmed that earth’s rotation actually twists thefabric of space and time.

An international group of scientists assembled by NASA hasconfirmed that Einstein was correct in his theory thatplanetary rotation would do this.

Scientists at the Joint Centre for Earth System Technologyand the University of Maryland measured a ?frame-dragging?effect on satellites orbiting the earth, suggesting that thepull of the Earth?s rotation on surrounding space causessatellites to shift slightly on its axis.

It also may be responsible for a whole range of differentphysical and even perceptual effects that are presentlylittle understood.

Is the Earth unique in harboring intelligent life? Even ifanother civilization is trying to contact us, it will soonbe too late, according to SETI’s Frank Drake, because TV isbeing delivered more and more by cable and satellites, whichdo not leak radio waves into space.

David L. Chandler writes in New Scientist that according toDrake, for ETS, “the Earth is going to disappear” very soon,since these signals “are the strongest signs of our existence.”

Scientists are speculating about what will happen if the melting ice caps cause the Earth to change its tilt. Would life would still be possible if this happened? One way to find out is to study other planets with tilts that are greater than ours.

Penn State Astronomer Darren M. Williams says, “I suspect, based on simulations and our own solar system, that many Earth-like planets will have spin axes that are tipped more severely than Earth?s axis.” He used computer programs to create planets with no tilt and with tilts of 54, 70 and 85 degrees. Earth’s tilt today is about 23 degrees.

The Earth may once have been surrounded by rings, like Saturn, which would have cast a shadow on parts of the planet all day long. The rings could have been formed after a glancing blow from an asteroid, when a space rock carves debris from a planet, then bounces off into the atmosphere. The resulting debris would also have shot off into space, and some of it would have ended up orbiting the Earth, forming a ring.

Peter Fawcett of the University of New Mexico and Mark Boslough of Sandia Labs say the debris ring would have cooled the planet by blocking or reducing the amount of sunlight it received in the tropics and subtropics. The rest of the planet would cool down too, because less heat would be transported from tropical regions to higher latitudes.
