WHAT MAKES THE SUN BURN?
Date: 1993 - 1999
Does space have oxygen?
If it doesn't, how does the sun burn?
The sun is like a continuously exploding H-bomb: it burns
by thermonuclear fusion reactions, that is, it emits energy
by fusing hydrogen nuclei into helium nuclei. You're right,
space doesn't have
Oxygen, that's why airplanes can't fly into space and
astronauts have to wear spacesuits.
