who shocked the world with a new theory toexplain the extinction of dinosours from the earth​

Answer 1

Answer:

Joseph Shklovsky

It Came From Outer Space. In 1956, Russian astronomer Joseph Shklovsky (1916-85) became the first scientist to consider the extinction was due to a single catastrophic event when he theorized that a supernova (the explosion of a dying star) showered the earth in radiation that could have killed the dinosaurs.
