...debris into the atmosphere, obscuring the sun, causing temperatures to drop and bringing on a long "winter" that killed much of the life on earth. But, at least for the dinosaur-extinction theory, there is a missing link: no one has yet discovered the huge 65 million-year-old crater that such a collision would have left...
...Triassic-Jurassic extinction, however, that evidence may exist. Less than 500 miles northwest of the Nova Scotia fossil find is the enormous Manicouagan impact crater, its outermost ring--clearly visible in satellite photographs--measuring more than 90 miles in diameter. Given the margins of error in dating, the age of the crater (about 214 million years) makes it suspect in the 200 million-year-old extinction...
...scene was numbingly familiar. A 550-lb. car bomb exploded in a crowded commercial section of Christian East Beirut, setting eight buildings ablaze and gouging out a 9-ft. crater in the street. The toll: 30 dead, l33 injured...
Disaster began when the celestial intruder crashed into what is now the Bering Sea, possibly creating a crater some 100 miles wide. The stupefying force of the impact, estimated at 100 million megatons, would have generated an enormous 3,000 degrees F fireball that would have spread outward at the speed of sound, igniting forest fires from North America to Asia. Several hundred billion tons of plants and animals would have been incinerated, sending great scarves of black smoke to join the impact dust in the stratosphere and circulate around the globe. What is more, because soot does not rain...
...results of the crater analysis were published in the British journal Nature, right beside the Nemesis report. Coincidentally, that same issue contained yet another paper on the death star. It was from Whitmire, who had independently conceived of a companion...
