Why would a nebulae explode if the pressure inside greater than the force of gravity?
A nebula can explode if the internal pressure exceeds the gravitational force holding it together because the gas and dust within it become unstable. When the pressure, often due to nuclear fusion or radiation from nearby stars, surpasses the gravitational pull, the material can no longer be contained. This imbalance causes the nebula to expand rapidly, resulting in an explosive event, such as a supernova or the dispersal of the nebula's material into space. Ultimately, this process contributes to star formation and the distribution of elements throughout the galaxy.

What two events can upset the balance between gravity and pressure in a nebula?
Two events that can upset the balance between gravity and pressure in a nebula are a supernova explosion or the collision of two nebulae. A supernova explosion releases an enormous amount of energy and can disrupt the delicate equilibrium between gravity and pressure. The collision of two nebulae can also disturb the balance by introducing additional gravitational forces and increasing the overall pressure within the system.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
What is a galaxy and what force holds it together?
An island comprising billions of stars and nebulae, held together by gravity.
Does a nebula move?
Nebulae can appear to move due to the effects of gas and dust within them being pushed and pulled by various forces such as gravity, radiation pressure, and stellar winds. However, their movement is relatively slow on human timescales.
What do astronomers believe are 'born' in nebulae?
Astronomers believe that stars, planets, and other celestial objects are 'born' in nebulae. Nebulae are vast clouds of gas and dust in space that can eventually collapse under their own gravity to form new celestial bodies. This process of stellar birth is essential for the formation and evolution of galaxies.

What is nebulae gravity?
The answer will depend on the amount of matter in the nebula.
What it be like if there was no gravity?
Without gravity, objects would float freely in space, and there would be no weight or pressure on our bodies. Everything would move in straight lines unless acted upon by another force. The lack of gravity would have a profound impact on how we live and interact with our environment.
Do nebulae change gravity?
Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.

This type of force keeps the sun and planets in their place?
Gravity put all matters of the Universe together, Stars, Galaxy, Nebulae and many other things.

What caused the interstellar cloud to collapse?
Nebulae are massive collections of gas and dust that usually are very cool around 5-30 kelvin. These nebulae are the remains of dead stars that have long died and have had enough time to cool themselves from the original energy release of the nova or supernova that created them. As the nebula cools the particles begin to slow down and once cool enough gravity will begin to collapse the nebulae and form what is known as a protostar. This is the birth of stars, and is essential for star formation.
