Mars Rock Older Than Thought

Rambo Tribble writes "The BBC reports on a finding, reported in Nature, (abstract), that the so-called 'Black Beauty' rock, discovered in the Sahara, is over twice as old as previously thought. The meteorite is now thought to be 4.4 billion years old, dating from a time in a nascent Mars' history that scientists are eager to know more about."

    Does Mars exist in this universe? Yes. Is it traveling at relativistic speeds? No.
    Therefore Mars and Earth time are similar if not the same.

    Also, we can communicate with Curiosity fine, except for a delay due to distance.

      To be older than human thought it easy. However, to be older than thought would require that the rock be older than thought anywhere in the universe. We lack evidence to decide that one.

    I think we can all agree that there is no reason to look back at the '70s.

    Assuming you are talking about time dilation, they are not going NEARLY fast enough (even on the ISS) for even a very expensive watch to be noticeably out of sync. The time difference is so minute you'd need 2 atomic clocks to even be able to measure it (1 on earth, the other in space).

    Time runs at different speeds at different points in space. The poster has a point. When astronauts return to earth their watches are slightly out of synch with clocks on earth

    RELATIVITY DOES NOT WORK THAT WAY

    The emphasized bit is correct, and another AC claimed "relativity does not work that way", which is incorrect, because relativity does work that way. Astronauts on the ISS experience a net dilation of 21 or so microseconds per day -- dilation of about 25 microseconds due to velocity relative to ground and compression of about 4 microseconds due to being higher up the gravity well. Over a 6-month stay, that would be about 4 milliseconds.

    While that's probably well within the margin of error of any mechanical watch, GPS devices are a different story. They have rather accurate internal clocks, and relativistic errors are large enough that GPS satellites have to compensate for the discrepancy.

    Thank you for doing the math. The 2 atomic clocks would definitely work then.
