at reading this i thought what? but i thought they had solid proof that that's what happened!
but apparently that isn't the case, scientists (WISE group) that there is no evidence of this actually happening. apparently the asteroid they thought that had broke off more than 160 million years actually broke off more than 80 million years ago. how they figured this out was by studying the main belts of mars and Jupiter finding the ancestors of the original asteroid. they found in their studies that fact. they got this also by the fact that it takes more than ten million years for an asteroid to arrive to earth.
when i read this article i was very intrigued by the fact that it takes an asteroid more than ten million years to reach our planet. other than that it was really boring. i know that it may excite scientists and all but it completely bores me out of my mind. but i also couldn't find any other article so..... had to use what i got. here's what the people had to say:
NASA scientist Amy Mainzer said: "This process is thought to normally take many tens of millions of years."Another NASA expert, Lindley Johnson, said: "As a result of the WISE science team's investigation, the demise of the dinosaurs remains in the cold case files.
"The original calculations with visible light estimated the size and reflectivity of the Baptistina family members, leading to estimates of their age, but we now know those estimates were off.
"With infrared light, WISE was able to get a more accurate estimate, which throws the timing of the Baptistina theory into question."
So the asteroid family that produced the dinosaur-killing remnant remains at large.
