A civilization can collapse for many causes such as drought, disease or being conquered.
the high mass star's core collapse because its gravity
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.
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.
When a star has burnt up all of its fuel and energy, it will collapse.
Anything that is a star now is something that has already collapsed to form a star.
Colony collapse is when bees mysteriously disappear. Vampire mites and nicotine-based insecticides are among the possible causes.
The life a star begins in nebulae. Clouds of dust and gas collapse upon themselves to form protostars. Further collapse from gravitational forces causes protostars to become main sequence stars. As time goes by, stars expand. Eventually, the star will collapse and explode. Depending on the original mass of the star, this explosion may result in a black dwarf, ,neutron star, or a black hole.
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole
The implosion process itself is called a "gravitational collapse". What remains of the star after the collapse can be a white dwarf, a neutron star, or a black hole.
Same as any cave collapse: erosion weakening the surrounding rock.
Causes of collapse for which rescue breathing may be needed are anaphylactic shock, heart attack, and poisoning.
The internal pressure of the star, and the 20 million degree heat, cause the star to expand. The massive gravity of the star causes it to collapse. As long as the Sun's nuclear fusion reaction is going on, it will maintain that balance. About 4 or 5 billion years from now, the Sun's hydrogen fuel will begin to run out, and it will start to collapse. The increasing pressure from the collapse will also increase the temperature, and when it reaches about 100 million degrees, the helium of the Sun will start fusing, causing the Sun to expand into a red giant. After a few billion more years, the Sun will slowly collapse again into a white dwarf star.
A higher-mass star will turn into a supergiant, then a supernova. Then, it will collapse and shed it's outer layer and leave behind a white dwarf. However, the star may collapse even further and become a black hole.
a strong gravitational force which means that the star will collapse in on itself
the cause of structures to collapse during earthquakes are upheavals of tectonic plates..
