Asteroid YR4

What if... a rogue planet grazed the Earth? the Earth left its orbit? the Earth stopped rotating? a meteorite crashed into the middle of the Atlantic Ocean? the Sun suddenly went out? a supervolcano erupted in the United States? humanity fell victim to a giant solar storm? a neutron star hurtled towards Earth? a black hole the size of a soccer ball grazed Earth? the star Betelgeuse exploded into a supernova? These are eleven apocalyptic scenarios exploring an unlikely but possible future. All of these extraordinary events are scientifically credible. Some of these catastrophes have even already occurred in the recent past. Proof of this can be found in the meteorite that crashed into the Yucatán and wiped out the dinosaurs... Each scenario is explained by a scientist recognized in their field.
