Dark matter (dark matter) is not meteorite or climate change that dinosaurs were extinct?

ByNASA's Marshall Space Fligh

It is said that on the earth 5 times in the past, organisms are mass extinct at the same time. One of them is mass extinction, which is thought to have occurred at the end of the Cretaceous period about 66 million years ago from now, so that it is thought that the dinosaur has disappeared from the earth. There are a lot of reasons why the dinosaurs who had been struggling with the face of the time to the extinction to the extinction of the earth at that time, the theory caused by the meteorite and the theory caused by the global volcanism activity However, Dr. Michael Rampino of New York University in the United States of America "Dark matter(Dark matter)I think that is the cause.

◆ Dark matter (dark matter)
Dark matter is a substance that can not be observed either by human eyes or even by optical instruments. It is dark matter that does not have electromagnetic interaction and does not have color charges, and has never been successful in observing with human hands. However, there are many phenomena in the universe that can not be explained by only substances and physical laws that can be observed at the moment, and what is necessary for explaining such events is a dark matter. In addition, it is believed that dark matter accounts for 85% of the substances present in the universe.

◆ Dr. Michael Rampino
Dr. Michael Rampino of New York University said that several years ago "Oult cloud"It was hypothesized that the comet might fly and it might have collided with the earth. This altitude cloud is a virtual celestial body which exists in the vicinity of about 50 thousand astronomical units from the sun, surrounds the solar system in a spherical shell shape, and it is thought that there are many comets here. Dr. Rampino said at the Astrophysical Journal Letters that a meteorite flew from Oort CloudHypothesis announcedwas doing.

However, in February 2015 Dr. RampinoMNRASPublished atThe latest paperThen, I guess that the cause of mass extinction is caused not by "meteorite collision" but by "dark matter". And it shows that this is also the cause of ancient large-scale volcanic activity.

Dark matter and galactic disk
Unlike substances composed of atoms, dark matter is thought to interact with each other by atoms and gravity. Astronomers can confirm that dark matter is present everywhere due to the influence of attractive forces (gravitational force) between dark matter, but it has not been possible to actually observe.

When looking at the photographs of the galaxy, things like light are spreading on the disk like a whirlpool from the center. This disk is called "Galactic disk"This galaxy disk is inconceivable unless gravity of dark matter exists. In the latest paper, Dr. Rampino reported that the solar system where the Earth exists is passing through the galactic disk at the cycle of 30 million years, and the gravity of the disk part and the gravity of the Earth act together each time it passes through, and the orbits of the heavenly body are disturbed It may be that it caused the "meteorite that caused dinosaur extinction" to be invoked to the earth.

◆ Dark matter and the earth
Dr. Lampino is not the only person claiming that "dark matter is the cause of dinosaur annihilation", but among them Dr. Lampino said "The mutual attraction between the dark matter and the earth causes dark matter We are accumulating "that is." In addition, Dr. Rampino said the particles that make up the dark matter are "Anti particleIt is also suggested that it is composed of.

If dark matter gathers on the core part of the earth, particles and anti-particlesPair annihilationIt creates big energy. The more dark matter gathered, the higher the rate at which particles and antiparticles pair annihilate. If pair annihilation occurs, large energy is born, Dr. Lampino presumes that this energy is enough energy to cause large volcanic activity.

In other words, the possibility that "dark matter accumulated over the years in the core part of the earth has annihilated, causing extensive volcanism and extinction of the dinosaurs" and the possibility that "as the earth passes through the galaxy disk Dr. Rampino seems to suggest both possibilities that it acted with dark matter, the orbit of the celestial body was disturbed, and the meteorite dropped.
