I think the solar nebula theory.
No, nobody uses the term "solar galactic hypothesis". You may be referring to a "solar nebula", in which a cloud of gas and dust collapses under its internal gravity to form a star and perhaps some planets.
That is called an accretion disk or a proto-Solar system.
the solar nebula was 98% hydrogen and helium gas

A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.

Interstellar dust
the solar nebula was 98% hydrogen and helium gas
young stars are found to have hot disks that surround them.
One theory is the Big Bang - after that, matter, including Earth, formed inside a solar nebula which later became our Sun.
An explosion from outside the nebula
The solar system was produced by solar nebula. The nebula was disrupted by an unknow substance in the air.
