About hydrogen in sun?

Question

The sun is made up of hydrogen. What if all the hydrogen in it is used up?

Answer 1

Hydrogen has many uses here on the earth. Depleting it from the sun can be fatal. It can get to situation which no man can control hence I prey it doesn't happen. 

Comments

Have you ever imagine a world without the sun? I mean nowadays lots of things are going around us which is unpredictable.

Answer 2

You already know that the sun contains atoms of hydrogen which are continuously fusing into helium. So if all the hydrogen is converted to helium then the inner core of sun contracts and 

outer layer will get expand.

After that it will be converted into giant .

Comments

So, it is possible that one day, such time will occur, when all hydrogen will get used up and there will be no sun?

Nothing can be said about that.

It  depends on God.

Hope that may not happen!

Answer 3

As we all know the sun is the mixture of various gases in which the percentage of hydrogen is very high which is about 73% so we can say that without hydrogen there is no sun in our galaxy.

Answer 4

The gravity of the Sun, which is almost 28 times that of Earth, ''traps'' hydrogen from its atmosphere and this hydrogen fuels the Sun's fusion reaction. At temperatures of 15 million degree Celcius in the Sun's core, hydrogen gas becomes plasma, the fourth state of matter.

Answer 5

It is composed of a mixture of 73% hydrogen, 25% helium, and 2% other elements by weight. The nuclear fusion reactions that produce the sun's energy are converting hydrogen into helium, changing the relative amount of these two elements present in the Sun.

Answer 6

Through nuclear fusion, the sun is constantly using up the hydrogen in its core: Every second, the sun fuses around 620 million metric tons of hydrogen into helium. At this stage in the sun's life, its core is about 74 percent hydrogen.

Answer 7

So if all the hydrogen is converted to helium then the inner core of sun contracts and 

outer layer will get expand.

After that it will be converted into giant .
