Why heat from the Sun Can propagate in the Vacuum Room?

As is known, outer space is a near-perfect vacuum; So how does the heat from the Sun propagate to Earth in this vacuum? Does heat need media for propagation? We will try to explain it scientifically in this article.

Actually, the answer is quite simple: heat is a form of energy released from sunlight and its propagation is done through radiation.

Still do not understand? You see, the heat energy in the sun can reach the Earth through the process of propagating energy (heat) in the form of electromagnetic waves without the need for intermediates.

That way, the heat from the Sun can reach the surface of the Earth without intermediates with this radiation process. An example of radiation heat transfer, for example, is when we conduct a fire activity.

When we are near a campfire, our bodies feel warm because of the heat transfer from the campfire to our body through the process of radiation. Although there is air around us that can transfer heat from convective awaiting fires, as we know the air is a poor conductor of heat (insulators).

In the process of radiation, heat moves in the form of light, because light can propagate in a vacuum, then the heat from the Sun can also travel in a vacuum so that it can warm our Earth.

The heat emitted by the Sun itself is the result of a process similar to that of an atomic bomb. That is, the Sun transforms the substance into a source of energy.

This is different from the burning process on Earth. Burning converts one substance into another, but when it is converted into a source of energy it requires very little substance to produce a large amount of energy.

Yes, the Sun is not really a massive flame like a fire on Earth's surface. The light and heat from the Sun come from a nuclear fusion reaction that converts hydrogen into helium. From that reaction, there is heat with a very high temperature, which we often complain in broad daylight.

The sun does not need oxygen to produce heat because it does not burn or comes from oxidation reactions, but fusion reactions like those mentioned above. The fusion reaction is the process of combining two "light" atoms (hydrogen) into a more "heavy" atom (helium).

The body of the Sun contains unusually high pressures so that this pressure forces two hydrogen atoms to combine to form a helium atom. However, in this fusion process, not all particles of hydrogen atoms are used to form helium atoms. Some of the particles of hydrogen atoms are released into energy or power sources.
