How does gravity affect stars?

How does gravity affect stars?

Gravity plays a crucial role in the formation, evolution, and death of stars. It is the force that causes gas and dust in space to collapse and form stars.

Can you explain the process of star formation?

Sure! Star formation begins in molecular clouds, where gravity pulls together gas and dust. As the material collapses, it heats up and eventually forms a protostar.

What happens to a star when it runs out of fuel?

When a star exhausts its nuclear fuel, gravity causes it to collapse. Depending on its mass, it may become a white dwarf, neutron star, or black hole.

How does gravity influence a star's lifespan?

Gravity affects a star's lifespan by determining its mass. More massive stars burn their fuel faster and have shorter lifespans, while less massive stars can live for billions of years.

Are there any exceptions to these rules?

Yes, there are exceptions! For example, some stars can undergo unusual processes like supernova explosions, which can alter their expected life cycles.
