Waspie_Dwarf Posted March 22, 2013 #1 Share Posted March 22, 2013 Dinosaur-killing space rock 'was a comet' The space rock that hit Earth 65 million years ago and is widely implicated in the end of the dinosaurs was likely a speeding comet.That is the conclusion of research which suggests the 180km-wide Chicxulub crater in Mexico was carved out by a smaller object than previously thought. Many scientists consider a large and relatively slow moving asteroid to have been the likely culprit. Details were outlined at the 44th Lunar and Planetary Science Conference. But other researchers were more cautious about the results. Read more... Link to comment Share on other sites More sharing options...
ozman Posted March 23, 2013 #2 Share Posted March 23, 2013 (edited) Study suggests a massive comet killed dinosaurs, not an asteroid The story of dinosaur extinction may be wrong, if a new scientific study of the Chicxulub crater in Mexico proves correct. The study’s authors argue that it wasn’t an asteroid that killed the dinosaurs off, but rather a comet. Edited March 23, 2013 by ozman Link to comment Share on other sites More sharing options...
tyrant lizard Posted March 23, 2013 #3 Share Posted March 23, 2013 I was going to write potato potato, but then I realised they were spelt the same. Not sure it made that much difference to the dinosaurs Link to comment Share on other sites More sharing options...
Frank Merton Posted March 23, 2013 #4 Share Posted March 23, 2013 It would be kinda ironic. The Chichilub event has been the main thing motivating the search for potentially dangerous asteroids. Link to comment Share on other sites More sharing options...
Zeta Reticulum Posted March 24, 2013 #5 Share Posted March 24, 2013 From what we are told, large meteors or comets impact every few million years or so. Galaxies collide, supernovas happen and black holes swallow stars, and maybe solar systems with them. Just like the continued warming and cooling of this planet over the eons - its going to happen no matter what we do. Link to comment Share on other sites More sharing options...
Waspie_Dwarf Posted March 26, 2013 Author #6 Share Posted March 26, 2013 its going to happen no matter what we do. Absolutely untrue. There is no physical reason why we can't deflect asteroids into safe orbits. There are many ways this could be achieved in theory and there are many people working on it practically. There are many natural disasters we are clueless about how to avoid, collisions with lumps of space rock are not one of them, Link to comment Share on other sites More sharing options...
xYlvax Posted March 26, 2013 #7 Share Posted March 26, 2013 Poor creatures.. I imagine what would evolve if we were to ever be wiped out by one. Link to comment Share on other sites More sharing options...
wolfknight Posted March 26, 2013 #8 Share Posted March 26, 2013 There is proof of a crater in Mexico. Some think it took about 100,000 year for them to all die out. Link to comment Share on other sites More sharing options...
