Mars Rock Older Than Thought 37
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.

What makes you so sure that "time" is the same on Mars as it is on Earth?
What makes you think they might not be?

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

And there is a time in Mars' history that scientists are NOT eager to know more about?
Vapid. Utter waste of bits. 'turning point' no less so. Troll video included.

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

No more reason than to look back at the 80's, or the 60's, or the late 1700's.

Humans became a sentient species only recently, on the geological time scale.
So a rock being older that thought itself, is not so surprising.

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.
