New study suggests that dinosaurs were not extinct because of an asteroid, this would be their terrible fate

The devastating impact remains firm in theory. However, there is new data showing in this new study.

Although there are different theories that address the extinction of the dinosaurs, this historical event is not stopped investigating. On this event there is a new study led by Harvard scientists. In it they detail that the disappearance of these species and many others from the planet was not due to a asteroid, but by another space body.

First of all, these scientists from Harvard they maintain the theory of the strong impact against the planet. In addition, they reaffirm that the crash was where it is today Chicxulub, on the peninsula of Yucatan, Mexico. However, new stellar data changes the object that collided with Earth.

The situation is like this: these experts say that instead of an asteroid, what hit our world was a comet. Is not the same? Many will wonder and the reality is what not. Therefore, we are going to make the differences clear. All with the intention of making understandable what the researchers are trying to explain.

Comet or asteroid?

In a brief explanation made by Astro Afición, they highlight that comets have a different formation than asteroids. Comets are made up of ice, dust, stone Y compounds organic. Consequently, when they approach the Sun they react by breaking up into several parts. Also, the force gravitational makes them pick up speed and they are shot everywhere in the solar system.

While asteroids are much more solid elements, made up of metals and rocks. They are much more stable and do not suffer as much from the consequences of approaching the massive star.

In this vein, the theory says that what impacted the land it was an object smaller than an asteroid, but at a higher speed. Something that made its consequences much more devastating.

The fragmented comet

The Study Finds portal reports that the comet in its maximum extension originated in the oort cloud. Massive objects like Jupiter are found in the path of these objects. The gravitational fields drive them to the Sun and this is when the devastating fragmentation occurs.

In a sun rubbing event, the part of the comet closest to the sun feels a stronger gravitational pull than the part farther away, resulting in a tidal force through the object. You can get what’s called a tidal disruption event, in which a large comet breaks into many smaller pieces. And what is more important, on the return trip to the Oort cloud, there is a greater probability that one of these fragments will hit the Earth « , is the explanation of Amir Siraj, one of the leaders of the investigation.

The age of the calculations they made on the separation of this comet is consistent with the age of Chicxulub. Not a minor fact when it comes to theorizing about the extinction of the dinosaurs.
