What is end of univers ???

Dear Student,
When the universe reaches heat death, everything and everywhere will be at the same temperature. All the stars will die, almost all matter will decay, and finally, all that will be left is a scattered soup of particles and radiation. The energy of that soup will be drained away over time by the expansion of the universe, leaving everything just a fraction of a degree above absolute zero. In this Big Freeze, the universe silent up with uniformly cold, dead, and empty everywhere.

If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually stop this expansion and precipitate the ultimate destruction. Galaxies, Stars, will smash into each other more frequently and kills off any life on the nearby planet.
Regards
