Earth's Oldest Rock Found on the Moon

realDonaldTrump inform us of a story:

Scientists may have discovered the oldest Earth rock ever—on the Moon. A lunar sample returned by the Apollo 14 astronauts may contain a bit of Earth from about 4 billion years ago. The research about this possible relic from the Hadean Earth is published today in the journal Earth and Planetary Science Letters.

An international team of scientists associated with the Center for Lunar Science and Exploration (CLSE), part of NASA's Solar System Exploration Research Virtual Institute, found evidence that the rock was launched from Earth by a large impacting asteroid or comet. This impact jettisoned material through Earth's primitive atmosphere, into space, where it collided with the surface of the Moon (which was three times closer to Earth than it is now) about 4 billion years ago. The rock was subsequently mixed with other lunar surface materials into one sample.

    You're being ridiculous: everyone knows that time travel is impossible.

    Blame it on Aristarchus. He's old enough to have left it there after a family picnic.

    I have seen the future:

    It's Donald Trump for 6 more years until 2024, then Ivana Trump 2024-2032. Next Donald Trump Jr. in 2032-2040, and Eric Trump in 2040-2048. Finally Barron Trump in 2048-2056.

      That wasn't the future you were seeing, it was a nightmare. The idea of a dynasty such as you describe is more appalling to me than a Hillary Clinton presidency. There probably ought to be an amendment preventing any such dynasty from happening. It would be a bitch trying to write it though. How to cover all the bases, without leaving loopholes, and at the same time not being overly restrictive?

        Yea, I always vote against dynasties. People seem to love them for some reason though...

        If people are willing to vote for that many Trumps in a row, then so be it.
