how does the sun burn when there is no oxygen by it?

The sun burns via nuclear fusion, a physical reaction, not fire which is a chemical reaction.

In 1:36 she says "as magnetic field lines emerge they form loops." Why are they loops instead of a straight line bursting through?

Magnetic fields always form loops instead of straight lines, it is a property inherent to magnetic fields.
