Question

what if there is no sun ​

Answer 1

Answer:

Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth's position in the solar system is optimal for the development of life.

Answer 2

If there is no Sun photosynthesis will be stop. The Sun,s immense mass draws all the other planets in the solar system toward it... If the sun were to suddenly disappear , Earth and the other planets would retain their forward motion, effectively flying off into outer space in a straight line . No one has any idea what would happen if that occured .
