A large asteroid impact (like the one that killed dinosaurs, approximately 6 miles wide) would cause immediate flash brighter than the sun, followed by shockwaves flattening cities, firestorms, mega tsunamis hundreds of feet tall, and global temperature crashes from dust blocking sunlight, potentially causing civilization collapse within weeks rather than years.

Earth is DOOMEDAñadido:
What if Earth had 24 hours left?
Scientists say a large [music] asteroid impact is one of the most realistic extinction threats. The asteroid that [music] killed the dinosaurs was about 6 miles wide. If something like that hit Earth today, the first thing you'd see is [music] a flash brighter than the sun.
Then a shockwave moving faster than sound would flatten cities.
Anything near impact, gone instantly.
Then comes the firestorms. Superheated debris would rain across continents.
The oceans would explode upwards. Mega tsunamis hundreds of feet tall would erase coastlines. Then the real nightmare begins. Dust and ash block sunlight. Temperatures crash.
Crops fail globally. Food disappears.
Civilization wouldn't [music] collapse in years. It could happen in weeks. And here's something wild. 99.4% [music] of people watching these videos aren't subscribed. Meaning only 0.6% [music] are.
So if you love crazy space facts, don't forget to like and subscribe for more interesting facts.
Now the scary question.
If scientists discovered an extinction asteroid heading for Earth tomorrow, would humanity actually work together?
