Our universe originated from a big explosion 13.8 billion years ago, and after a long historical evolution, it gradually evolved into a colorful world today. Everything we see now is the product of the Big Bang.
The energy generated instantly by the Big Bang is incalculable. After the Big Bang, the most violent explosion in the universe was the collision of supernova explosion and neutron star , but these two explosions are nothing in front of the Big Bang.
On Earth, the huge burst of energy we can see may be a tsunami. For example, the super tsunami that occurred in Indonesian in 2004, released energy equivalent to the energy of hundreds of billions of tons of explosives exploded at the same time, and the energy of two thousand nuclear bombs.
Also, the energy generated by the impact of the asteroid hits the earth, and the impact instantly is also incalculable.
Scientists have predicted that every 100 million years, more than 25 kilograms of species on Earth will become extinct. The culprit is the meteorite in the sky. These meteorites are the residues from the birth of the sun 5 billion years ago, and are still aimlessly wandering in the solar system.
Some meteorites will change their orbits due to external factors and may head straight to the earth. When a meteorite hits the earth, due to its extremely fast speed, it usually brings super high energy and even brings catastrophe to the entire earth.
An asteroid with a diameter of only a few kilometers may cause a catastrophe to organisms on the surface of the earth. For example, the meteorite 65 million years ago has a diameter of only about 10 kilometers, which is not worth mentioning in front of the earth.
However, the moment when a meteorite hits the earth, it can reach more than 10 times the speed of the bullet. It can instantly shovel more than 100 million tons of rocks and throw them into the air, and the energy generated is equivalent to the power of a thousand nuclear bombs.
That meteorite impact on the earth directly led to the extinction of dinosaurs. You should know that dinosaurs have ruled the earth for more than 100 million years. In addition to dinosaurs, more than 3/4 of the species on Earth have also become extinct.
The reason for the extinction of species is not only because of the huge energy generated in the instant of impact, but the dust generated after impact almost covers the entire earth, blocking the sunlight, and the environment changes greatly. Many species cannot adapt to the environment and go to extinction!
In the solar system, the Kuiper belt, and the Ort Cloud, there are a large number of meteorites and comets and . They wander in the solar system, and slight orbital changes may make them head straight for the earth, causing devastating blows to the earth.
There have been five mass extinctions on Earth, and the most recent one happened 65 million years ago. The mass extinction of species predicted by scientists is only a probability that it will happen in 100 million years, and does not mean that it will happen, but as long as it happens, it will definitely be devastating, so humans must prepare for the future!
