What would happen if all the hydrogen present in the Sun is converted into helium?

Explanation: When all the hydrogen is converted to helium the Star rearranges itself, its core shrinks and its outer layers expand, depending on its initial mass the Star then transforms into a giant or a super-giant.

Will the universe eventually run out of hydrogen?

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. These will run out of hydrogen about 1013 years from now, and slowly cool.

How much does hydrogen take up in the universe?

Approximately 73\% of the mass of the visible universe is in the form of hydrogen. Helium makes up about 25\% of the mass, and everything else represents only 2\%.

When the Sun has fused all of the hydrogen in its core into helium what will be its next fuel source?

If your star is more than 8 times the mass of the Sun, it will not only fuse hydrogen into helium and helium into carbon, but will initiate carbon fusion later on, leading to oxygen fusion, silicon fusion, and eventually, a spectacular death by supernova.

What will happen when all the hydrogen from the Sun is used up?

Once all the hydrogen gets used up, the sun will grow out of this stable phase. That’s when the sun will become a red giant. For about a billion years, the sun will burn as a red giant. Then, the hydrogen in that outer core will deplete, leaving an abundance of helium.

What will happen if hydrogen gas in the core of the sun is used up in a nuclear reaction?

In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

What happens when we run out of hydrogen?

Eventually the core of the star runs out of hydrogen. When that happens, the star can no longer hold up against gravity. Its inner layers start to collapse, which squishes the core, increasing the pressure and temperature in the core of the star.

What will happen to the Universe once all of the hydrogen has been consumed?

Low-Mass Post-Main Sequence Evolution Once they have consumed their core hydrogen, gravitational core collapse causes the core to heat up. For stars with less than 0.5 solar masses however, their is insufficient mass to generate the temperatures need for the helium in the core to start fusing.

Why does hydrogen make up most of the universe?

The element Hydrogen has only one proton and one electron and is the only element which has no neutrons. Therefore it is considered as the simplest element in the universe and gives a valid reason for it to be the most abundant and common element in the universe.
