    Two key predictions of Albert Einstein's general theory of relativity have been confirmed by NASA's Gravity Probe B mission, scientists announced this week.

    "We've completed this landmark experiment testing Einstein's universe, and Einstein survives," principal investigator Francis Everitt, of Stanford University in California, said during a press briefing.


    The change is so small, in fact, that Einstein didn't think measuring it was even possible.

    In his 1953 book The Meaning of Relativity, Einstein wrote that frame-dragging effects "are actually present according to our theory, although their magnitude is so small that confirmation of them by laboratory experiments is not to be thought of."

    But now, "thanks to NASA," Everitt said, "we've done more than think about them. We've actually measured them."


    Interesting article for us science nerds.
  2. Wow. Can anybody really understand this without having a physics Ph.D?
