Gravity.
Gravity and Inertia
the pressure pushes the nebula together just like magnets to keep it from falling or collapsing, and the gravity pulls the exess debri into the nebula to keep it packed tight.
Gravity works with Pressure to keep a Nebula from collapsing.
The nebula will explode.
All bodies that have mass, have gravity. The Helix Nebula is a large planetary nebula and will have "loads" of gravity.
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
Yes, particles in the nebula attracted to one another by gravity?
A nebula IS a cloud of dust and gas loosely held together by gravity.

The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
The answer will depend on the amount of matter in the nebula.
