What really killed off the dinosaurs?

 Broken chunks of an asteroid may have doomed the dinosaurs

What doomed me?

 We already know that the climate-changing consequences of a large asteroid or other object hit the earth near the Yucatan peninsula in Mexico 66 million years ago. This object is called the Chicxulub Impactor, with an impactor being something that hit or impacted the earth and Chicxulub referring to its location. We don't know yet much about the actual nature of this impactor, but presumably it was an asteroid. The impact of this object, which was between 3 to 50 miles wide, killed off 75% of life on earth, including all of the dinosaurs except birds. Now a new theory from an astrophysicist and his student at Harvard university hypothesizes that the object was in fact not an asteroid, but a part of an asteroid that broke up as it bounced off the gravitational fields of different planets. This object pin-balled off of Jupiter's immense gravitational field and slammed into earth at an angle that made it uniquely destructive. However, other scientists do not accept this theory and prefer to stick with the older asteroid idea. See the video and articles to learn more:
