New evidence confirms that meteors once crashed into the earth

An international team of scientists has discovered nearly 13,000 years old sediment at the bottom of Lake Cuitzeo in central Mexico. This sediment contains a group of strange materials, including nanoscale diamond particles and small spheres formed after the collision between objects in the universe and the earth.

These data are the latest evidence to confirm the controversial hypothesis, that a collision between cosmic and earth objects occurred 12,900 years ago, when the earth was in an unusually cold period.

The researchers conducted a thorough examination, and discovered a family of diamond nanoparticles, including lonsdaleite - a diamond nano-form that only occurs when a collision occurs in the universe. The researchers also found small spheres that collided when moving rapidly during a collision. These objects cannot be formed by human intervention, volcanic eruptions or other natural processes on earth, but only appear during the collision with outer space objects, GS. James Kennett at UC Santa Barbara, explained.

These data indicate that a comet or a meteorite - possibly a radius of several hundred meters - has entered the atmosphere of the earth. The temperature emitted from this impact burned trees, melted rocks on the surface, and caused great environmental disturbances.

'These research findings are in line with previous North American discoveries about changes in ecosystems, the disappearance of large animals, changes in culture and human population. " Professor Kennett said.
