The dangers can destroy mankind

Every scientist affirmed that the end of the world will not happen tomorrow, December 21, but some experts acknowledge that humans can be extinct by super volcanoes, dark meteorites or cancer.

Professor Jocelyn Bell Burnell, the British astrophysicist once discovered the pulsar (extremely fast rotating neutron stars), thinking that civilization could be a dark meteorite. According to her, if a dark meteorite is about 10 km wide hit the earth, human existence will end, Fox News reported.

Humans can detect most meteorites thanks to ice and snow on their surfaces. But dark meteorites do not have or have very little ice or snow. In addition, their surface is covered by a large amount of dust which makes their ability to detect them decrease.

A dark meteorite can hit the earth and cause famine across the planet.

Burnell said the collision between a dark meteorite and the earth could not destroy all people on the planet, but a huge amount of dust would fly into the air and spread across the globe, causing billions of people to die out of the disease. Respiratory. Due to dust blocking sunlight, spring, summer and autumn will disappear, giving way to the long winter. Because the temperature dropped to an extremely low level and the sunlight disappeared, a deadly food crop caused famine to erupt across the planet.

Dr. Dave Rothery, a volcanic researcher at the Open University in England, thinks civilization can perish by the outbreak of a super volcano. If a super volcano erupts, its dust also floats in the atmosphere, preventing sunlight and causing hunger like the scenario of Professor Burnell.

"Dust and sulfur dioxide gas from super volcanoes will paralyze the photosynthesis of plants , " Rothery said.

The apocalyptic scenario of Bryan Lovell, the former president of the British Geological Society, is a huge amount of methane (CH ₄ ) that will escape the ocean after an earthquake in the seabed. Methane is one of the greenhouse gases. Because the amount of methane in the atmosphere increases dramatically, the temperature on the earth's surface will increase sharply, making humans extinct by extreme weather phenomena.

Vivienne Parry, who once led the BBC television program Tomorow's World, thinks that one day humans will be annihilated by a cancer of the fox. The most intimate dog, the animal, will become a "bridge" for the cancer of the fox to infect people. The fox will bite the dog. The bite of the fox causes the dog to get cancer. Then, when the dog bites the person, the cancer will spread to humans.

Other theories about apocalyptic events include: a black hole devouring the earth, super solar storm attacking the Earth, reversing the Earth's magnetic field, extrasolar planets hitting the globe.
