Some scientists, esoteric and scientific fiction periodically predict the death of all life on our planet as a result of the end of the world. In this issue we will talk about those creatures that can survive such global catastrophes.
Of course, everyone heard about the extinction of dinosaurs 65.5 million years ago, as a result of the Earth’s collision with an asteroid. But few people know that this has happened to our planet more than once. For example, 199 million years ago, under unexplained circumstances, half of the currently known species that lived on Earth at that time died out. The probable reasons for this are a massive volcanic eruption or, again, a collision with an asteroid. And, of course, we could not get past the so-called Great Permian extinction that happened 251 million years ago. At that time, 95% of all marine species and about 70% of terrestrial vertebrates died. The catastrophic consequences could be caused by a sudden release of methane from the seabed, as well as increased volcanic activity in Siberia, which is currently taken as an aspen hypothesis.
At the moment, mankind is threatened by a huge number of factors that can lead to global extinction. These are technogenic accidents, nuclear wars, global warming and, of course, the fall of asteroids on Earth, from which we have not yet learned how to defend ourselves. You can find out more about this in our previous release, a link to which can be found at the end of the video.
So after all, which creature can survive in almost any conditions? These are microscopic low-speed invertebrates, the first records of which date back to 1773. Modern scientists have repeatedly argued that these cute creatures, whose size can barely reach a millimeter, will give odds to any plants and animals in terms of survival in the most extreme conditions. They are able to withstand up to +150 degrees Celsius and the temperature of absolute zero, and this is for a moment -272 degrees! Zero pressure for them is absolutely harmless, however, as well as what is at the bottom of the Mariana Trench – the deepest on our planet. If we talk about radiation, then the radiation dose of 10 gray, deadly to humans, will not be felt at all by these animals, because they can withstand radiation 620 times more!
In conclusion, we would like to emphasize that a supernova explosion or the fall of a huge asteroid will erase all references to man forever, but the sluggish ones will most likely live here until the Sun expands, which is planned in about one billion years. Then it will begin to turn into a red giant, which in consequence will absorb not only the Earth, then Mercury and Venus.
