Are we safe from a sudden asteroid strike? No, says India's first meteor scientist

The most devastating extinctions, when almost the entire life on earth was wiped out, had happened in prehistoric times. The most recent was 66 million years ago when dinosaurs were killed off.

Though scientists are still not agreed on what caused these mass extinctions - global warming or oxygen depletion in seas or meteor hits or massive methane leaks from ocean ice or COVID-like epidemics or hell-hot hurricanes called hypercanes - there is a general consensus that the dinosaur-ending disaster, called the Cretaceous Event, was caused by an asteroid hit.

Acid attack
It is said that a giant asteroid some 15 km wide had dropped on the Earth obliterating nearly 70 per cent of the Earth's species including dinosaurs. It is not as if right on impact a 15-km wide asteroid crushed the entire life on earth with a circumference of over 40,000 kilometres.
