or is it 30-miles wide? sigh the article is not clear.
“The 300-mile-wide crater lies hidden more than a mile beneath the East Antarctic Ice Sheet. And the gravity measurements that reveal its existence suggest that it could date back about 250 million years — the time of the Permian-Triassic extinction, when almost all animal life on Earth died out.
Its size and location — in the Wilkes Land region of East Antarctica, south of Australia — also suggest that it could have begun the breakup of the Gondwana supercontinent by creating the tectonic rift that pushed Australia northward.
Scientists believe that the Permian-Triassic extinction paved the way for the dinosaurs to rise to prominence. The Wilkes Land crater is more than twice the size of the Chicxulub crater in the Yucatan peninsula, which marks the impact that may have ultimately killed the dinosaurs 65 million years ago. The Chicxulub meteor is thought to have been 6 miles wide, while the Wilkes Land meteor could have been up to 30 miles wide — four or five times wider.”
They’re saying that the metor itself may have been 30 miles wide, so a 300-mile-wide crater would not be implausible.
The real question is, how did Karl Rove do it? And why?
What nefarious reason did the Rethulican Master of Minds have to go back into time and wipe out all living things? What was it that had grown up during that time that would have given the DNC an advantage in the next election?

No wonder lefty trolls do this. It’s actually kind of fun trying to think this crap up.
