Even before I saw this video, I suspected that more than one asteroid killed the dinosaurs. In fact, so many space rocks of all sizes hit earth throughout its history that it added to the size and mass of the earth. More mass means more gravity. Stronger gravity meant land animals could no longer grow as big as dinosaurs. That explains why today's animals cannot grow much bigger than the African elephant. It also explains how some Pterosaurs could fly back then when they were as big as today's Giraffe (earth was smaller back then, hence it had less gravity).

Pete, I always suspected that millions more asteroids/meteor hit earth throughout its early history than just one that killed the dinosaurs. Look at the surface of the moon for reference. But here's a kicker that no one came up with except me: All those millions upon millions of rocks that hit earth throughout its history added more mass to the earth. More mass means stronger gravity. Stronger gravity means land animals can no longer grow as big as dinosaurs. I am surprised no scientists proposed such a hypothesis.

Here's an interesting phenomenon: According to Einstein, the closer you are to a source of gravity (or the stronger the force of gravity), the slower you age. Since Voyager is now very far from Earth and the Sun (source of gravity), does it age a lot faster than if it had been on earth? Does that mean that it is not 44 years old but over 100 years old? Any Theory of Relativity experts out there care to chime in?
