People can destroy themselves long before the death of the Sun Source:

over time, our native star will become hot

Once, in about five billion years will destroy our planet. When the life cycle of this heavenly body will come to an end, the number of atoms of hydrogen and helium in the core of the star will decrease, which will cause the Sun to glow brighter and brighter, destroying the next planet and Earth including. In the end, the Sun will become a red dwarf — a small and relatively cool star, emitting little light. However, we don't have to worry about what will happen with our planet over billions of years. Most likely, human civilization will disappear much earlier.

Why you need to look for other planets?

Because in the Universe nothing is forever, at some point, our planet will not remain and a trace. And that's fine. As he writes in his newspaper column in the astronomer and chair of astronomy Department, Harvard University AVI Loeb is very important to our species moved to other parts of the Universe that are not so close to the fluctuating brightness . According to Loeb, we should not remain confined to the existing planets and moons. After the successful colonization and nearby interstellar space, we can create genetically identical copies of themselves, as well as flora and fauna, to sow life on other planets. Note that AVI Loeb no doubt that extraterrestrial life in the Universe exists or existed before.

Thinking about the future of humanity, Loeb notes that once we solve the main problems associated with space flight that will be very difficult, mankind should focus on copying themselves and other species, before we will all be destroyed by the blinding brightness of the home star. According to astronomer we also need to focus on the search for exoplanets. Recall that in September, scientists announced the discovery of water vapor on a potentially habitable planet K2-18b. This exoplanet is a super-Earth which orbits a star at a distance of 110 light years. K2-18b — the only known planet outside the Solar system that has water, an atmosphere and temperature range that allows the water not to freeze on the surface. However, her column Loeb finishes pretty grim, considering that our civilization will continue to exist very long:

I'm inclined to believe that our civilization will disappear as a result of wounds inflicted on ourselves long before begins to pose a threat. Why do I think so? Because it was discovered a huge number of potentially habitable exoplanets, but no traces of intelligent life is still not detected. This may indicate that advanced civilizations have a life much shorter than their stars.

it is possible that our species will cease to exist within 100 years

What are the threats facing our civilization?

Scientists from Oxford University argue that 99% of ever species on our planet . Especially amazing looks our desire to consider ourselves invincible. According to scientists our existence is as fragile as everything else on this planet, and the odds that human civilization will disappear at any moment, frighteningly high. Analyzing man-made disaster such as nuclear war, and linking it with natural disasters such as volcanic eruption or asteroid impact, a team of researchers from Oxford University found that in 2020 the probability of death of our civilization is 200 times the chance of winning the lottery. published in the journal .

Moreover, according to some scientists right now we are in the midst of the sixth mass extinction, which was caused by man. Given the number of threats facing humanity, the destruction of life on Earth as a result of the growing brightness of the Sun over billions of years looks the least scary.
