Scientists in Scotland say Asteroid that hit the Earth until the dinosaurs disappeared Not just one, but two.
Foreign news agencies reported that A group of scientists has come out to prove that the giant asteroid that hit the Earth and caused the extinction of the dinosaurs 66 million years ago was not the one man But there is another, smaller asteroid. It also fell into the sea off the coast of West Africa at the same time. Until it caused a big hole called “Nadeer”
Scientists say that the fall of the second asteroid was terrible, creating a tsunami at least 800 meters high that spread over the Atlantic Ocean.
Dr. Eusdine MacNicholas from the University Harriet-Watt, in Scotland, was the first to be discovered. “Nadir Basin” (Nadir Crater) in 2022, at that time he did not know yet How did it happen? But Dr. Nicholson and his colleagues are now sure that the nine-kilometer-long fall is caused by an asteroid hitting the seabed.
They still cannot pinpoint the exact time when this happened. Or did this asteroid come before or after a large asteroid impact on Earth? which causes the 180-kilometer Chicxulub Crater in Mexico and brought an end to the dinosaur era.
However, a team of scientists said that Asteroids smaller It also came in the last period of the Cretaceous period. And his fall will turn into a big ball of fire.
“Imagine that Asteroid hits Glasgow And you’re in Edinburgh, about 50km away, and this fireball is 24 times bigger than the sun in the sky, strong enough for the trees in Edinburgh to set it on fire,” said Dr. Nicholson, adding that is what followed. loud noise before an impact as strong as a magnitude 7 earthquake occurred
A lot of water spreads out from the seabed. before you get back together again This leaves a unique mark on the ocean floor.
The fact that there is a large asteroid like this It will always hurt closer to our planet in a short time. This is unusual, and Dr. Nicholson’s team does not know why he fell into two Earths.
In addition, scientists believe that The asteroid that caused the Nadir Basin has a width of about 450-500 m and fell into the Earth at a speed of about 72,000 km / h. world that can be found there now
NASA estimates that if Bennu really does fall into the world It will happen on September 24, 2725, but the chance of it happening is about 1 in 2,700.
