What causes a nebula to collapse into a dense of mass?
A nebula can collapse into a dense mass when its gravitational attraction overcomes the outward pressure of gas and dust within it. This collapse can be triggered by external forces, such as a nearby supernova explosion or a shock wave from a passing star, causing the nebula to start contracting due to gravity. As the material compacts, its density increases, eventually leading to the formation of a protostar or a star.
What are two competing forces in a star?
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.
What force makes a red super giant collapse?
a strong gravitational force which means that the star will collapse in on itself
What causes a meteor to shine like a star?
Meteors shine like a star because of the friction with Earth's atmosphere as they travel at high speeds. This causes the meteor to heat up and glow.
Is a stellar nursery the same as a star nursery?
Yes. It's where stars are "born" and start undergoing fusion on their own.
What causes the collapse of a star?
The collapse of a star is based on its age. When it runs out of "Fuel" its inside contracts as the outside expands. it can then super nova or collapse into a tiny star.

What is the main force that causes a star to undergo gravitational collapse and transform into a black hole?
The main force that causes a star to undergo gravitational collapse and transform into a black hole is the inward pull of gravity, which becomes stronger as the star's core runs out of fuel and can no longer support itself against its own gravity. This collapse results in a dense, compact object with a gravitational pull so strong that not even light can escape, creating a black hole.
Is friction responsible for the formation of a star?
No. A star forms when gravity causes a nebula to collapse. As the gas compresses it heats up. eventually, the heat and pressure ignite nuclear fusion.
How are a black holes started?
It is believed that they usually start from the gravitational collapse of a massive star - once it runs out of fuel.
What happens when a star uses its hydrogen?
When a star uses the hydrogen in its core it will start burning hydrogen in a shell around the core and become a red giant. After that the star will either collapse into a white dwarf or start fusing helium, depending on its mass.
How do all-stars start as?
They begin as a Nebula star, than they evolve into a main sequence star, then to red giant (which would be doomsday), then to white dwarf, then finally, to a super nova star which has a core that could turn into a neutron star.
Why can an iron core not support a star?
An iron core cannot support a star because iron cannot undergo nuclear fusion to release energy, which is necessary to counteract the force of gravity pushing inwards on the star. This lack of energy production causes the star to collapse under its own weight, leading to a catastrophic event like a supernova.
What happens star's furnace stops?
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
Were did a black hole come from?
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole
Why can iron fusion not support a star because of iron?
Iron fusion cannot support a star because iron is the most stable element and cannot release energy through fusion reactions. This causes the star to collapse, leading to a supernova explosion.
How stars go supernova?
Massive stars. See related question: 2nd Answer: Yes, massive stars, but ones with another star like a red giant orbiting each other. The to-be supernova 'sucks' material from the other star near it until its mass is large enough to make the star collapse and burst.
