The mystery of dinosaur extinction has long been a contentious topic in the scientific community. Darwin's theory of evolution suggested that dinosaurs became extinct due to aging and competition from emerging mammals, but this perspective fails to explain why dinosaurs vanished so suddenly in just a few million years. Another theory posits that dinosaurs suffered from chronic poisoning due to consuming toxic alkaloids from gymnosperms, ultimately leading to their extinction. However, modern scientists argue that these viewpoints overlook the time required for species extinction, which does not align with actual evidence.
As research progressed, an increasing number of scientists turned to astrophysics for answers. In 1979, Luis Alvarez from the University of California, Berkeley, proposed the "asteroid impact hypothesis," suggesting that an asteroid collision with Earth could be a key factor in the dinosaurs' extinction. Subsequently, several hypotheses such as the "Nemesis hypothesis" and the "galactic wandering hypothesis" were introduced to explore the deeper reasons behind dinosaur extinction. These theories not only involve planetary movements and stellar systems but also investigate the power of cosmic rays and their impact on Earth's life forms.
Recent studies indicate that dinosaur extinction was a gradual process rather than a sudden event. This complexity adds to the challenges of existing theories in fully explaining this phenomenon. Nevertheless, scientists continue to explore and strive to uncover this ancient mystery.
