In the late 1980’s, there was very little acceptance among geologists and
geoscientists that giant asteroids, the size of mountains, had impacted our
planet.
Today,
a mere ten years later, there is almost universal agreement among scientists
that Earth has experienced several enormous impacts. Funny, isn’t it, how
science has radically changed its course of thought in such a short time! The
notion that Earth has been pummeled by giant asteroids was regarded as
scientific lunacy in 1978 when geoscientist Dr. Luis Alvarez, (University of
California at Berkeley) first advanced the idea that the dinosaurs became
extinct because of an asteroid impact. Today, however, the evidence of asteroid
impacts on Earth is indisputable. More than 150 impact sites have been
identified and studied. One of the largest impact craters (about 175 miles
across) is located in the Gulf of Mexico. In fact, many scientists now believe
the dinosaurs became extinct worldwide because of the Mexico impact.
