CATACLYSM WILL COME AND THE WORLD WILL EXTINCT- WHAT DOES THE SCIENCE SAY?
Hydrogen, which is in large portion in the mass of the Sun changes by atomic bond into Helium atom sun gives light by this act. After 5oo years pass on, Hydrogen, which is in the center of the Sun, will be exhausted. At that time, no atomic bond will happen in the center of the Sun. As there is no thermal energy in the center, the central nucleus of the Sun will shrink by gravity. Due to this reason, the top layer enlarges and the sun gets the form of a monster. This is called as ‘red giant galaxy’. This is the cataclysm said by science. This kind of cataclysm will not come soon.
However, the earth meets many challenges like global warming, and seasonal changes. There is also a danger of polluting the environment artificially, by ourselves.
