how is the sun burning...?

Question

if there's no oxygen in space? is it a different type of fire or something?

Answer 1

The Sun is basically a thermonuclear bomb with a built-in thermostat. Just as in a hydrogen bomb, hydrogen atoms are fusing together to make helium atoms and this nuclear reaction produces heat (along with the light that we see). If the reactions go on too fast, the Sun expands slightly (just like a balloon expands when you heat up the air in it). This slows down the reactions and then the Sun cools and contracts. If it contracts too much, the nuclear reactions speed up, and then the Sun heats up and expands again. So the Sun stays at the same temperature, burning its nuclear fuel at a steady rate. At the rate it is going, we have about 4 billion years left until the Sun burns out .Your question was smart , so I stared you !!!!!!!!!!

Answer 2

The suns energy is not from the combustion of stored chemical energy. It is from the fusion or combination of hydrogen nuclei. Two protons combine to form another isotope of hydrogen known as deuterium. When two atoms fuse they lose a small amount of mass which becomes binding energy. This binding energy is described by Einstein's equation E=MC^2 Some of this energy is emitted. Energy is also produced from the formation of theoretical particles and their subsequent annihilation. Deuterium atoms also combine to form isotopes of helium releasing further energy. Theoretically this energy takes millions of years to reach the surface of the sun and head to earth.

You know truly everyone who has answered this question so far knows nothing of nuclear fusion. Some of the greatest scientists have tried to explain it in various theories. But I am a skeptic and believe no one except god truly understands any function of the universe. IF you passionately interested spend four years of undergraduate and graduate school learning how otherwise i might as well tell you there is a magical lamp in the sky and that is equally believable.

Answer 3

The sun does not burn. It generates heat and light through a process called fusion.

Fusion is when, under very high pressure, atoms are forced together (like two balls of clay) to form a new atom. In the case of the sun, hydrogen atoms are being fused to create helium.

The high pressure comes from the size of the sun - it's so big that it weighs on iself, and that creates the pressure that allows for fusion.

This process generates huge amounts of both light and heat, which make their way through space to Earth.

Answer 4

Someone asked this same question yesterday.

The Sun does not "burn". The sun is so massive that its gravity compresses hydrogen gas together, thereby raising its temperature so high that its hydrogen atoms undergo a type of nuclear reaction called "fusion".

So the sun and other stars are nuclear fusion reactors.

Answer 5

Technically its not burning as that implies it is combining with oxygen. It is a nuclear fusion reaction. Hydrogen is being converted to helium and releases a lot of energy in the process.

Answer 6

Atomic fusion -- the same process as the Hydrogen bomb.

A hydrogen atom and a deuterium atom are fused under extreme pressure to form an atom of helium, releasing a huge amount of energy in the process.

Answer 7

It is a different kind of fire called nuclear fusion:
Though there is some disagreement about the exact process, one view is:
1H + 1H → 1D + 1p (D is deuterium, p is positron)
1D + 1D → 1He + 1p + energy
2p + 2e → energy

Answer 8

It is not burning. It is nuclear reacting. That requires no oxygen and also makes MUCH more heat and light than filre could.

Answer 9

Fusion of hydrogen atoms.

Answer 10

Atomic fusion
