5. black hole
A point in space with infinite mass and infinite density. Not even light can escape it's gravitational pull.
Scientists study black holes in order to determine how intense gravity dilates time relative between those near it and those observing it.

1. black hole
An area of space-time with a quantum singularity at its center. The singularity has a theoretically infinite mass, making it impossible for even light to escape. Around the singularity is an Event-Horizon. This is also known as the point of no return because it is the critical area that light can no longer escape from, and time itself comes to an end, or is at the same time ad-infinitum. Much work has been done on this subject by Stephen Hawking.
A black hole is an inescapable point of space time.

2. Black hole
The vagina of a woman who has sex very often. It is very stretched and gapping. And once something goes in, in never comes out
I heard that Tomy fell into Gina's black hole. He aint never comin back.

3. Black Hole
A black hole is a point of infinitely dense space with such a high density that no matter or energy may escape. It is formed when a supermassive star supernovaes. It has enough gravity, however, that it will collapse inward on itself. Normally, when this happens, the Palaui Force cannot resist gravity's push (this means that electrons orbiting a nucleus of an atom are pushed inward to the nucleus), and forms neutronium (a superdense form of matter made of only neutrons). Normally, this dense ball of matter forms a neutron star, but in extreme cases, the ball of matter is so dense that it collapses inward on itself. Nothing can stop this collapse once it has started, and it will not end until the matter reaches a point of 0 dimensions (0 feet high, wide, and deep). This forms the singularity of the black hole. There is also a "point of no return", or the event horizon. Once you have crossed this sphere circling the black hole, you will be ripped apart atom by atom, and strung out to an infinite length (called spaghettification). This process will take an infinite amount of time, and nothing will ever get you out. There are also two different types of singularities (that we know about). There are stationary and spinning. In a stationary singularity, the singularity is a single point where the curvature becomes infinite. However, in a spinning singularity, said singularity becomes 2 dimensional, stretching in both space & longitud...

4. black hole
The vagina of a emo. It gives no pleasure and is a void of nothingness.
Guy 1-"Damn, that girl was hot!"
Guy 2-"Yeah but dont walk to close, shes got a black hole."

6. black hole
Apparently in the black community, this is a racist term because it has the word "black" in it without any words of praise surrounding it. Because of its political incorrectness, please note that it has now been renamed an African American Quantum Singularity.
John Wiley Price, the Mayor of Dallas and a black judge recently were offended and demanded an apology (no, I'm not making this up) for a white councilman referring to the traffic office as a "black hole" where paperwork is sent and never seen again. "How would you like it if I called it a 'white hole'?" Mr. Wiley-Price immediately retorted. Next on the list: Blackjack, Blackberry and Blackbird.

Some crazy ass outerspace shit that will completely fuck you up if you go near it.
Yo, jimmy went to chill wit that black hole, and he got fucked up!!!
