Dinosaurs' extinction which happened 65 millions years ago is not an isolated phenomenon!
If we look at the extinctions curve, which indicates how many species have disppeared during each epochs, we see ten peaks!
These ten peaks are all separated by exactly 26.2 millions years!
That means for 250 millions years, two massive extinctions are always separarted by EXACTLY 26.2 millions years!
If dinosaurs' extinction was due to a meteorite, we don't understand why this meteorite would have struck the Earth and killed dinosaurs exactly at the expected time!
Probability that meteorites kick the Earth exactly each 26.2 millions years is...one upon one million!
On the contrary, the change of the gravitational constant G, and the
change of gravitation may be a regular phenomenon!
