My 12 yr old kid asked me last night ...."dad is there air in space ?"
Being the all knowing Dad i said "no son theres no air in space ! it's a vacuum"
Well then he said ....how does the sun burn so brightly without oxygen?
D'OH !

I didn't know....so c'mon guys dont fall over in the rush but will someone give me the answer.......Thanks

The simple answer is that the sun isn't on fire, but rather that it is shining brightly because it is hot, just like a lightbulb.

The more elaborate answer is that the sun is actually made up of a super-heated plasma, plasma being a fourth state of matter, like solid, liquid, and gas.

Okay Thanks Aquatus !

I like hearing little 'uns asking good science questions! Maybe another Einstein on our hands.

Here's a handy link if interested further

The stars are sustained by a gigantic nuclear reaction. It accounts both for the heat and brightness (radiation) of a star.

Fission, right?

It depends on the chemical reaction cause to my understanding, some chemical just needs itself to burn

The Sun 'burns' nuclear fuel that does not need oxygen.  Nuclear energy
comes in two forms:  fission in which heavy elements are broken down into
lighter ones; and fusion in which light elements are 'fused' together to
make heavier elements.  Stars 'burn' by nuclear fusion.

Fission, is one way I believe.[attachmentid=11370] Fission is a nuclear reaction in which an atomic nucleus splits, or fissions, into fragments, usually two fragments of comparable mass, with the release of large amounts of energy in the form of heat and radiation. In the UWNR, Uranium-235 is the fuel and it is struck by a moving neutron, which combines with the U-235 to become U-236. Because of the mass and energy imparted to the nucleus by the neutron, the nucleus has enough energy to fission and breaks down into two (or more) smaller nuclei and two or three new neutrons which together have less mass than the original U-236 nucleus. This missing mass, sometimes known as the mass defect, is changed into energy.

Fusion also qualifies.[attachmentid=11372]Energy can also be produced by combining light nuclei in a process is called nuclear fusion. As an energy source, fusion has several advantages over fission: the light nuclei are plentiful and easy to obtain, and the end products of fusion are usually light, stable nuclei rather than heavy radioactive ones. There is one considerable disadvantage: before light nuclei can be combined however, their mutual repulsion must be overcome due to the fact that the positively charged protons of the nuclei repulse each other. Because of this problem, fusion reactors are not yet producing electrical power. This is an area of great research interest in the field of nuclear engineering and physics. We at the UWNR do not perform fusion experiments.

My belief has been that the sun gets it’s raw supply from the vacuum it’s self. Which contains infinite supplies of hydrogen and helium, space is not exactly just empty, hydrogen and helium is abundant in space. Yes I can fathom the theories by other members.

My thoughts.

Pfft, you handled that situation all wrong this is what your supposed to do.......

Kid:Dad, is there air in space?

Dad:No son, theres no air in space! it's a vacuum

Kid:How does the sun burn so brightly without oxygen?

Dad:............Go to your room!

There ya go, thats what you're supposed to tell him thumbsup.gif

I wish more kids asked those questions now days. laugh.gif
