When will the world end and what would happen?

Answer 1

answer 2 Yes, the world will end. Our Sun at the end of its life will become a Red Giant star, and will envelop the Earth. The earth and Solar system are about 4.5x109 years old. By 10x1010 years of age, the Sun will be a Red Giant, and by 10x1011 years of age, it will have shrunk to a White Dwarf.

(so we have experienced a few % of the Sun's life.)

These data may be derived from study of the Hertzsprung - Russell diagram.

i believe it won't end because that's what they said in 2006 and it didn't endd!!!

that above is lode of donkey poo

Answer 2

The world will end in approximately 5 billion years. The sun, having run out of hydrogen gas to fuel its nuclear fusion, will lose its hold on its outer gaseous layers. These superheated gasses will expand outward and either engulf the earth, completely destroying it, or settle past Venus, making the earth molten once more. After this red giant phase, the sun will become a luminous ball of superheated iron known as a white dwarf, which would be incapable of sustaining life on earth.
