A decrease in the overall volume of gases like hydrogen can prevent nuclear fusion in a nebula.
Explanation:
Nuclear fusion: The reaction of combining two or more atomic nuclei to form one or more different atomic nuclei and subatomic particles is known as nuclear fusion. A single heavy nucleus is formed from two lighter nuclei. Helium is made by fusing Hydrogen atoms together.
Nebula: A nebula is a giant cloud dust and gas in space. Nebulae are formed out of the gas and dust that are thrown out by the explosion of a dying star.
A decrease in the overall volume of gases like hydrogen can prevent nuclear fusion in a nebula.

Explanation:
Extremophiles are organisms that have been discovered on Earth that survive in environments that were once thought not to be able to sustain life. These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold. Different organisms have developed varying ways of adapting to these environments, but most scientists agree that it is unlikely that life on Earth originated under such extremes.
