More ruthless than meteorites life killer! Scientists: Creating the largest extinction of life on Earth
The Earth, from a chance 3.8 billion years ago, began to derive its history of life! Life, from scratch, has experienced hundreds of millions of years of reproduction, evolution, and change, but for most of them, in the end, can not escape the grand and wonderful after the curtain - biological extinction. This process is no longer a simple cycle of life and death, but rather a sudden restart button for life on earth, in a relatively extremely short geological time, the number of living organisms and populations of the rare dramatic decline occurred.

How long has it been on Earth since we left at the speed of light and returned at the speed of light a year later?
If an astronaut leaves Earth at the speed of light and returns at the speed of light a year later, by common sense, two years should have passed on Earth by the time the astronaut returns.

Study finds that sharks use Earth's magnetic field to guide them like a map
Sea turtles are known to rely on magnetic signals to find their way across thousands of miles to the beaches where they hatch. Now, in the May 6 issue of Current Biology, researchers report some of the earliest conclusive evidence that sharks also rely on magnetic fields for long-distance trans-oceanic voyages.

Don't look for extraterrestrial civilization, there is one within the Earth, scientists: in front of it human is a higher civilization
In the wilderness of the northeastern region of Brazil, there is a large colony of huge white ant nests, presumed to have existed 3,000 to 800 years ago and still in use and under construction until now. Its total area is about 228,000 square kilometers, and the mounds of earth visible on the surface exceed 200 million, which can even be photographed in outer space. By no coincidence, there is a giant red ant 1 on the seashore of Hokkaido The colony contains more than 300 million worker ants and 1.08 million queens, which live in 45,000 interconnected crypts that spread over an area of 27,000 square kilometers.

Newly discovered a super-Earth! 30% is water, only 100 light years away, there may be life
Everything in the universe is made up of various elements, but the proportion of these elements in the universe is very uneven. Two elements, hydrogen, and helium occupy 73.9% and 24% of the mass of the observable universe, respectively, while among the other elements, oxygen occupies the largest proportion, with its mass occupying about 1% of the observable universe.

If the end of the world comes, how many people, at least, will be needed to continue the human race?
You might not imagine that it doesn't take very, very many people to continue the human race as you might think. There are so many end-of-the-world scenarios in movies and TV shows, and the environment of the earth is deteriorating in real life, so we can't help but worry. Whether it is a biological crisis or a super earthquake, or climate deterioration, humans always have the instinct to survive and the desire to continue the race. So, if the end of the world does happen, how many people do we need, at least, to be able to continue the human race?
