What happens when all the stars in the universe burn out?

Eventually the cycle of star birth and death will come to an end. Gravity will have won, a victory delayed by the ability of stars to call on the resources of nuclear fusion. But ultimately, gravity will reduce all stars to a super-dense state as black holes, neutron stars or cold white dwarfs.

Will the universe fade away?

Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black. All lingering matter will be gobbled up by black holes until there’s nothing left.

Will the universe ever run out of stars?

Of course, no matter what happens, the birth of new stars must eventually cease, since there’s a limited amount of hydrogen, helium, and other stuff that can undergo fusion. This means that all the stars will eventually burn out. These will run out of hydrogen about 1013 years from now, and slowly cool.

Are we going to run out of energy?

Conclusion: how long will fossil fuels last? It is predicted that we will run out of fossil fuels in this century. Oil can last up to 50 years, natural gas up to 53 years, and coal up to 114 years.

What will happen if there are no stars in the universe?

An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. There will also be neutron stars and black holes left over from the time where there were stars in the Universe. The Universe will be completely dark.

Is it possible for the universe to become completely dark?

Technically, it will never be totally dark. Assuming that the universe end via the “Big Freeze”, that is. The background microwave radiation will always be out there, it will just get colder and colder as space expands.

What will the universe look like in the future?

There will also be neutron stars and black holes left over from the time where there were stars in the Universe. The Universe will be completely dark. A future observer might notice the occasional flash, when some object interacts with a black hole.

Will the dark ever go away?

Yes, finally it will. To a “when….” question like this, there is only one answer : Yes, it will, but it’s correct answer depends also on the when-factor. Light can “travel” for trillions of years and “dark” is just our notion of observing light. It say’s nothing about reality.
