the spiral form is the result if the two principal vectors at work on the particulate masses. These are the incoming linear velocity and the attraction to the centre of capture (Black Hole?) which exercises a high gravitational pull which increases the velocity of the particle.

∙ 13y agoGalaxies have a spiral pattern due to 'density waves' in the galaxy. Stars in a galaxy orbit much faster than the spiral arms, and pass through the spiral arms quite quickly. However many stars share similar orbits, that tend to line up and create dense packets of stars, what we see as a spiral arm.
They are essentially 'traffic jams' in a galaxy. A traffic jam can last for hours, even if the average car only sits in it for 10 minutes at a time.

What are the types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
How many galaxies are spiral?
Approximately 60% of all galaxies are spiral
How many barred spiral galaxies there?
It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.
How many types of spiral galaxies are there?
Yes. There are two types of spiral galaxies: "S" (normal spiral) and the less common "SB" (barred spiral, with an elongated center).
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
What are the 3 common galaxies?
galaxie 1, 2, 3, 4 and 5
Are there at least 60 billion spiral galaxies in the universe?
There at least 60 billion spiral galaxies in the universe because the spiral galaxies comprise of about 60 percent of all galaxies which are about 100 billion.
What are 5 different galaxies?
spiral, eliptical, cartwheel, barred spiral, and lenticular galaxies
The local group contains mainly spiral galaxies?
No. It has only 3 big spiral galaxies, but dozens of dwarf galaxies.
How did the spiral galaxies get its name?
because it was spiral
How old are barred galaxies?
Barred galaxies per se do not exist. They are just a sub category of spiral galaxies of which about 2/3rds are barred spiral galaxies.
