How The Sun Burns Without Oxygen In Space

Outer space holds astonishing mysteries of the universe that force us to completely rethink our familiar earthly experience. The main question that perplexes researchers and amateur astronomers is why the Sun burns in a vacuum, if there is no oxygen in outer space. On Earth, absolutely any fire instantly goes out without fresh air, but our star has been emitting enormous amounts of heat and light for over four billion years. The secret lies in the fact that in the depths of this star, not the usual chemical combustion occurs, but a powerful thermonuclear fusion. Scientific facts explain in detail how, under the monstrous pressure of gravity, a hydrogen nucleus overcomes resistance and fuses into helium. At this moment, a tiny fraction of the mass is converted into pure radiation, according to Einstein's famous formula. Every second, the star loses millions of tons of matter, converting it into light, which pierces the incandescent labyrinth of density for over one hundred thousand years. Gravity compresses the gas, and the thermonuclear explosion pushes it outward, creating a perfect natural balance. This thermostat keeps the star stable and prevents it from detonating. But what happens when its hydrogen fuel runs out? The star will rapidly swell, turning into a red giant, engulfing nearby planets and scorching their oceans. Our Earth is also involved in the final stages of becoming a hydrogen giant, becoming a hot desert until its core transforms into a white dwarf.
