Why is the sun on fire even if there is no air present in space?


What is weather actually? State of atmosphere surrounding the earth is what is called weather. Atmosphere is considered the gaseous mantle (mostly oxygen and nitrogen) encasing the earth and rotating with it in space. Of the three significant segments making up a fire situation (Fuel, Weather and Topography), the weather is the most significant, yet it is constantly evolving. 

But did it ever occur to you, Why is the sun on fire even if there is no air present in space? Yes, I know you are wondering why did it never cross your mind before? Hello and Welcome to another mindblowing episode of random thoughts. 

In this episode, we are going to discuss facts about sun being on fire when there is no air present in space. Before moving further let me remind you of subscribing to our channel and press the bell icon so you will get the notification for our next videos. Let’s think…

How is the sun burning

The sun doesn’t really “burn” in a way like a fire. The sun is for the most part included hydrogen and helium which is under massive pressure made by gravitational force in the sun’s core. The pressure is extraordinary to the point that it raises the temperature of these gases so unimaginably high that atomic fusion happens. The procedure of atomic fusion consolidates lighter atoms into new, heavier elements and discharges an enormous measure of energy as light, heat and other electromagnetic radiation. These various types of radiation is the thing that makes the sun so sweltering and brilliant.

In about 5 billion years, the sun will go through the entirety of its hydrogen and helium fuel, become a red mammoth and may expand out the extent that the circle of the Earth, conceivably immersing our planet all the while. In the end, the expansion will stop, and the external layers of the sun will scatter into space deserting a white smaller person, which is a similarly little and thick sphere of issue that will shine and radiate (with no further combination) for billions of years past the presence of the sun in its present state. Sooner or later, the entirety of its residual energy will dissipate abandoning a dark diminutive person. On account of bigger, progressively massive stars, their lives can end in increasingly fantastic style with a supernova explosion, which is one of the most enthusiastic infinite marvels at any point found. 

Individuals will in general utilize the expression “burn” freely with regards to stars, since they take fuel (gases), and transform their atoms into energy through combination. On Earth, “consuming” commonly alludes to the procedure of combustion, which includes a fuel joined with heat and an oxidizer (most every now and again oxygen from the atmosphere) to create flame just as energy. Despite the fact that they are totally various procedures, the distinguishable final product is heat and light.

It is accepted that similarity is the reason the expression “burn” is utilized all the more by and large with regards to talking about how stars utilize their fuel, despite the fact that it’s not actually precise. For certain individuals, it feels increasingly normal to state, “the sun burns gases to create energy” instead of all the more effectively expressing, “the sun wires hydrogen and helium into heavier components to deliver energy”. Albeit “burning” may not be actually right in reference to stars, it sounds progressively natural, when as a general rule, the sun is basically a gravity-moderated nuclear fusion reactor.

No burning response in Sun

There is no burning response in the sun. The sun has enough mass to generate inside of it the high pressure region, where hydrogen molecules transform into helium iotas with nuclear combination which releases a significant amount  of energy. 

You realize that there are nuclear reactors on earth that create electricity, they don’t “ignite with oxygen” not one or the other. The sun is the greatest nuclear reactor in our star system.

Sun sure is the Hottest

The Sun is made up primarily of hydrogen gas.Its core is by far its hottest part.

In addition to the intense heat, there is an incredible amount of pressure at the Sun’s core. In fact, the vast amounts of hydrogen atoms in the Sun’s core are compressed and heated so much that they fuse together.

This reaction, known as nuclear fusion, converts hydrogen atoms into helium. The by-product of nuclear fusion in the Sun’s core is a massive volume of energy that gets released and radiates outward toward the surface of the Sun and then into the solar system beyond it.

The nuclear fusion reaction that occurs in the Sun’s core is similar to the reaction that produces the mighty explosion in a hydrogen bomb. Of course, the fusion reactions that occur in the Sun’s core are almost-infinitely more powerful than a hydrogen bomb. So why doesn’t the Sun explode?

The outward pressure created by the fusion reactions in the Sun’s core are balanced by the inward pressure created by the gravitational force of all the gases that surround the core. Stars can and do collapse or explode if the fusion reactions at their cores become too weak or too strong.

Fortunately for those of us living on Earth, the Sun’s outward and inward pressures are nicely balanced for the next 1 billion years resulting in a steady stream of energy coming our way.

If Space is Vacuum How are we breathing?

Humans are on a planet where gravity holds down an atmosphere. The sun has an atmosphere as well yet it is so fantastically enormous that at its center, the weight from all that gravity makes lighter components intertwine and discharge gigantic measures of energy. That energy in the end makes it way out and we see sunlight. 

There is some ‘burning’ occurring in the sun’s upper atmosphere. Any oxygen that lands in its atmosphere would rapidly respond with different things and ‘consume’ however as it went deeper it’d separate again rapidly. The measure of burning material is endlessly little and insignificant yet it’s not 100% precise to state there is NO ‘burning’.

Hence, The point is made that sun isn’t burning in the space it is something similar to the earth burning at it very core like lava. Sun also had its own atmosphere and sun has the gases like helium and hydrogen and the sun is a. star so it has enough high temperature to nuclear fusion so that release the energy and that is light energy but that is not the burning of the sun.
