A giant asteroid hit Earth and killed the dinosaurs 66 million years ago – or did it really do it?

A recent study has cast doubt on the popular theory that an asteroid strike killed the dinosaurs.

Are all the techniques used to track and discover details about asteroid strikes and their impact on planets, especially Earth, wrong? The most popular scientific theory says that 66 million years ago, an asteroid collided with Earth and caused the extinction of all dinosaurs. The best technological tools for examining the evidence have been published to reach this conclusion. But is that really how things happened? A new study, shocking, disagrees. Accordingly, asteroids have nothing to do with the demise of the dinosaurs. Contrary to popular belief, it was volcanic eruptions that contributed to the death of all kinds of dinosaurs. This may sound silly, but the study has some evidence to support its claim. Read on to find out what it is.

Study challenges asteroid theory and technology behind it

A large amount of data was collected by seismographs in 1996. A total of 650 km of area was explored to confirm that Chicxulub crater on the Yucatan Peninsula actually coincided with carbon dating of the time when the dinosaurs became extinct. Later, in 2005, a deep two-dimensional penetration of the area was carried out using seismometers on the ocean floor to perform a comprehensive analysis of the velocity of the structure. This set of data helped locate the craters to find the signature of the asteroid’s remains.

Asteroid or volcanoes: What killed the dinosaurs?

This study was published In Proceedings of the National Academy of Sciences (PNAS). The researchers claimed that continent-wide volcanic eruptions caused this mass extinction. But at the same time, the study does not denounce the role of the asteroid in all this. But for them, instead of being the main catalyst, it only adds fuel to the fire.

“All other theories that tried to explain why the dinosaurs were killed, fell out of favor when the asteroid crater was discovered,” he said. He said Brianne Keeler, associate professor of earth sciences at Dartmouth College in New Hampshire and co-author of the study.

And he feels confident in his assertion, backed by the data. After looking at the data of similar impacts that caused the extinction, inconclusive evidence was abandoned, which means that the relationship between the Chicxulub asteroid and the extinction of the dinosaurs was not a definitive theory.

However, researchers discovered that four out of five mass extinctions occurred due to volcanic eruptions. “While it is difficult to determine whether a particular volcanic eruption caused a particular mass extinction, our results make it difficult to ignore the role of volcanoes in the extinction,” Keeler said.

The volcanic eruption caused by the extinction would be preceded by massive amounts of lava that filled large parts of the Earth’s surface, making it uninhabitable. Carbon dioxide and other toxic gases will also fill the atmosphere, creating a large toxic chamber. Also, soot and dust would rise high and cover the sky to block out the sun’s rays and cause a mini ice age on the planet.

Could it be how the dinosaurs died? As yet there is no way to prove it, and while it is an idea worth considering, it is also true that there is a huge amount of evidence for the fact that an asteroid caused the extinction of the dinosaurs. Of course, the truth will be discovered in the court of science.
