Were there any sightings of white holes or black holes in the last 100 years?

Black holes have been detected (or at least evidence of their activity) White holes have never been observed, and remain theoretical for the time being.

Are black holes dangerous from where you are?
Not much. The closest (known) black hole is at a distance of about 3000 light-years.
Can black holes die?
They slowly evaporate over X amount of googleplex years.
Did scientist send unmanned spaceships into a black hole to gather information?
No. The nearest known black holes are many light-years away. Everything we know - everything we THINK we know - about black holes is theoretical. Guesswork.
What happens when two black holes collide?
If two black holes collide, they will orbit each other for months-years (depending on mass), unable to escape each others gravitational pull. The bigger black hole of the two will eventually suck in the smaller one when it reaches its event horizon, ultimately forming an even bigger black hole.
What is the closest a black hole has been to earth?
The closest known black hole is at a distance of about 3000 light-years; it seems likely that black holes closer than this will be found eventually.
Is there moor black holes than white dwarfs?
One black hole is created a week approxiametley. A white dwarf takes a GIANT amount of time, billions of years just to make one. And they have to go through the process of a medium sized star, which takes a couple billion years to go through.
How long is it to get to earth to the black holes?
The closest known stellar-mass black hole seems to be at a distance of a few thousand light-years. Of course, there may be black holes that are closer, but that are not known as such yet.The closest known stellar-mass black hole seems to be at a distance of a few thousand light-years.

Why are you safe from black holes?
Why am *I* safe from black holes? Because the nearest one from my planet is 1600 light years away. I don't know if that means YOU are safe from black holes -- I don't know the distance between your planet and the nearest black hole -- but I know my safety is assured.
If the Universe is devoured by black holes and since black holes don't have an end does that mean the Universe never ends?
The black holes may not devour everything since the outward velocity of the matter in the universe may escapethe gravitational pull of the black holes. Stephen Hawkins reckons that even the mass in the black holes would diminish over time, though over trillions and trillions of years.
Are black holes dangerous to people?
Black holes could be dangerous to people if people were close to a black hole, but there are no black holes near the planet Earth (as far as we know) and the closest one is probably in the center of the Milky Way galaxy, which is about 80,000 light years from Earth, which is a safe distance.
Where can black holes be found?
If space men are brave enough they can go far far far away into space and that is probably find one.There are black holes all over the galaxy. They result from the collapse of larger stars. The closest known black hole is a few thousand light-years away, but there may well be black holes nearer to us.There are black holes all over the galaxy.

Black holes where can you find them?
The nearest know black hole is at a distance of several thousand light-years. There are probably black holes closer by, but they are hard to detect, if they don't happen to be part of a close binary star system.The nearest know black hole is at a distance of several thousand light-years.

Where do you find a black hole?
The nearest known black hole is at a distance of about 6000 light-years, but it is quite possible that there are black holes closer to us.
Where is the closeies black hole?
The nearest known black hole is a few thousand light years away, but it is likely that there are black holes nearer to us.
