The lighter the star, the longer near-life could exist.
A group of international astrophysicists from Harvard and Oxford in the course of their research identified the time during which still survive humanity.
According to scientists life on Earth will become impossible after 3-4 billion years.
The corresponding statement of the scientists appeared on the pages of foreign scientific publications. The fact is, as explained by the experts, as long will exist the light, by which life began on the planet.
Since life originated on Earth due to the Sun, and all living things will die because of him. Today the Sun is under development, which is called “yellow dwarf”. His next step will be “subgiant” which the Sun will reach approximately 6.5 billion years. Reaching this stage, the Sun would simply “dissolve” the Earth in its plasma. However, scientists suggest that humanity will disappear sooner, namely after 3-4 billion years.
