The gravity generated by a collapsed star massive enough to form a black hole compresses the fabric of four dimensional time-space into a single dimension (called, appropriately enough, a singularity).
If you were immune to the effects of gravity and able to approach the singularity at the center of a black hole with a flashlight (whose beam was equally immune to the effects of gravity), you still wouldn't be able to see the collapsed solar mass since it exists in a lower dimension than the one we reference (1 dimensional instead of 4 dimensional).
When a star is old and expands it turns into a black hole.
When it turns into a black dwarf neutron star or black hole.
The collapses star gets squeezed by collapses gas and turns into a black hole.
The collapses star gets squeezed by collapses gas and turns into a black hole.
A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
A black hole originated as a star, that is, the star converted to a black hole.
A black hole does not create a star. A black hole is formed when a star dies.
A neutron star or a pulsar, or a black hole.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
It happens when a star 8 times bigger than the sun(if the star is bigger it uses up more fuel/hydrogen)starts to run out of fuel and turns helium into heavier elements and when it finally reaches iron it collapses and turn into a neutron star, then a black hole.
There's no mass range that's between "collapses into a neutron star or pulsar" and "collapses into a black hole". It'll be one or the other.
A black hole starts as a dying star. As the star gets smaller as it dies, the inner pressure becomes so powerful that the star implodes. When this happens, the smashed atoms of the dead star come together to form a neutron star. When this is crushed to nothing, a black hole is formed. If a black hole does not get enough energy, it will decrease in size and eventually explode.
