Have black holes become larger since they were first discvered?

The size of the black hole - that is, the diameter of the event horizon - will increase if the mass of the black hole increases. Over time, black holes normally do gain extra mass from attracting it through gravity. However, they can also lose mass via Hawking radiation and eventually evaporate. Hence, the age of a black hole has little relevance to its size.

∙ 10y agoThat is very likely, since any matter that falls into a black hole will make it larger. However, I don't think this has been actually verified - the time elapsed since the first black hole was discovered is quite short, compared to the lifetime of a black hole.

It will first become a red giant, then turn into a white dwarf and in billions and billions of years it will become a black dwarf.
Do you put on the red terminal first or the black?
Always red first then black when assembling. When disassembling always black (neg) first.
Why does F have a larger first ionization energy than O?
First ionization energy increases as u move from left to right,so oxygen comes first than florine which means when u pass oxygen to florine the ionization energy become more than it was in oxygen.
What is a super-massive black hole?
A supermassive black hole is a black hole with a very large mass, millions to billions times the mass of the sun. The supermassive black hole in our galaxy is about 4 million times the mass of the sun.
How heavy do the star cause black hole?
When a stellar remnant is over about 3 to 4 times the mass of the sun (see Tolman-Oppenheimer-Volkoff limit) it is estimated to have insufficient outward pressure to resist gravitational collapse into a black hole. Note that larger stars would often explode into a supernova or become a planetary nebula, losing most of their mass this way first - perhaps over 75 percent - and thus the original star's mass needed to have a remnant heavy enough to collapse in a black hole would be much heavier than 3 times solar mass.
When a number is being added to a positive number does the first number become smaller or larger?

Why is the sun considred a black hole?
First of all, our sun can not become a black hole, it is too small for that. However if a star is three times bigger than our sun, then yes it will become a black hole.
