A white dwarf is the final stage after the death of a star roughly the size of our sun. It is composed mostly of nickle and iron metal (the end products of nuclear fusion) and is initially very hot (i.e. "white"). Eventually it will cool off becoming a black dwarf and nearly impossible to detect.
A black hole is the final stage after the death of very massive stars. The mass of the star is so great that the force of gravity completely overwhelms any repulsion of the other three forces and quantum effects that prohibit matter from occupying the same place. The entire star's mass collapses into a single infinitesimally small point and an "event horizon" forms around this point where gravity is so strong that nothing including light can escape out of and anything falling through it will fall into that point with no chance of escape.
Stephen Hawking also hypothesized that the big bang also created many microscopic black holes that due to quantum effects radiate mass and energy faster and faster as they get smaller, until they suddenly explode destroying themselves. (Note: black holes created by the collapse of large dead stars cannot do this)
What else can I help you with?
What is the difference between white dwarfs and black dwarfs?
their colour is one thing but a black dwarf originates from a white dwarf
What difference between a white dwarf and a black hole?
A white dwarf is a white hot solid ball of nickel-iron alloy, a black hole is an infinitesimal singularity of infinite density surrounded by total emptiness.
What is the difference between a red giant and a white dwarf?
size and color
What is the relationship between a black dwarf and a white dwarf?
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.
What does a white dwarf eventually become?
A black dwarf.
Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
What is the difference between black and white shade?
there isnt, or white can be black shade with white color pencil
White dwarf which has stopped radiating energy?
a black dwarf
What do you think the difference is between a black dwarf and a supernova explosion?
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
What is a cooled white dwarf star that is extremely dense?
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
What is formed as a white dwarf loses its energy and is smaller than a black dwarf?
As a white dwarf loses energy and cools down, it eventually transitions into a black dwarf. A black dwarf is a hypothetical stellar remnant that has cooled to the point where it no longer emits heat or light. It is smaller and denser than a white dwarf.
What is the difference between orange and black tigers and white and black tigers?
White Tiger : White with Black stripes Leopard : Golden with Black unique spots Jaguar : Black with No markings
