− | | | + | | Black holes are created by stars going into supernova, and occasionally by two stars colliding. On the contrary, regular holes are often created by humans using shovels, as well as small mammals such as moles or dogs. Of course, this is by no means limited only to small mammals. Many animals, from elephants to ants, are also known to create this kind of hole. |

Those metals are often underground, and are thus recovered by a mine, i.e. a regular hole. |

It is considered possible that at least some of this 'missing mass' is in the form of black holes. It is not generally considered an option that ordinary holes have anything to do with this. |

In particular, there's the eponimous classic ''{{w|The Black Hole}}'' and more recent films such as ''{{w|Interstellar (film)|Interstellar}}'', both about space missions that encounter a black hole. {{w|Journey to the Center of the Earth}} is a classic novel by {{w|Jules Verne}} (and made into {{w|Journey to the Center of the Earth (1959 film)|various}} {{w|Journey to the Center of the Earth (2008 theatrical film)|films}}) which involves going into a volcano tube (a kind of hole). H. P. Lovecraft's 1921 short story ''{{w|The Nameless City}}'' involves the explorer narrator venturing into an ancient tunnel (entered through a hole) dug by a pre-human civilization under the Arabian peninsula, and ''{{w|At the Mountains of Madness}}'' involves tunnels lost in the continent of Antarctica. <!-- Unsure of satisfying the criteria for 'famous', or 'sci-fi', or I might include further links to The Core, The Descent, Evolution, Star Trek: The Wrath Of Kahn (or TOS: "The Devil In The Dark"!), Rendezvous with Rama, etc, etc --> |

− | | The {{w|Black hole information paradox}} is a paradox arising from a contradiction between two widely-accepted theories related to black holes. Scientist {{w|Stephen Hawking}}, famous for his research into black holes, said that black holes release their energy over time, eventually disappearing, through {{w|Hawking Radiation}}. According to this theory, if information was also to enter the black hole, it would be released alongside this radiation.

According to this theory, if information was also to enter the black hole, it would be released alongside this radiation. On the other hand, the {{w|No-hair theorem}} states that all black holes are completely identical outside of three key features: mass, spin, and electric charge. If information that fell into a black hole is released with Hawking radiation, then that means that there ''must'' be more than three properties of black holes. |
− | + | On the other hand, information that falls into a normal hole is not lost forever, and can likely still be reobtained, especially if the information is stored physically. Hawking and {{w|Kip Thorne}} famously made a {{w|Thorne–Hawking–Preskill bet|bet}} with {{w|John Preskill}} over this paradox. | |

Sinkholes from dissolved limestone are generally entrances to [https://caves.org/ caves] that explore further limestone dissolving from underground waterways. Florida is known for its warm underwater caves [https://www.smithsonianmag.com/science-nature/science-behind-floridas-sinkhole-epidemic-180969158/ and opening sinkholes]. |
