unusual facts about black hole



Baryonic dark matter

Candidates for baryonic dark matter include non-luminous gas, Massive Astrophysical Compact Halo Objects (MACHOs: condensed objects such as black holes, neutron stars, white dwarfs, very faint stars, or non-luminous objects like planets), and brown dwarfs.

Black hole electron

In physics, there is a speculative notion that if there were a black hole with the same mass and charge as an electron, it would share many of the properties of the electron including the magnetic moment and Compton wavelength.

Construction of a complex null tetrad

At some typical boundary regions such as null infinity, timelike infinity, spacelike infinity, black hole horizons and cosmological horizons, null tetrads adapted to spacetime structures are usually employed to achieve the most succinct Newman-Penrose descriptions.

Hoop Conjecture

The Hoop Conjecture, proposed by Kip Thorne in 1972, states that an imploding object forms a black hole when, and only when, a circular hoop with a specific critical circumference could be placed around the object and rotated.

Jól á leið til jarðar

Two inexperienced angels from heaven must deliver a casket containing the holiday of Christmas to Earth in time for Christmas Eve, as the evil Öngull attempts to steal the casket, and sink it in the deepest black hole in space.

Katherine McAlpine

At the end of 2009 McAlpine released a new rap video on YouTube dealing with the unfounded fears surrounding experiments in CERN that could lead to the creation of a black hole which eventually would swallow the entire earth.

Planck particle

A Planck particle, named after physicist Max Planck, is a hypothetical particle defined as a tiny black hole whose Compton wavelength is equal to its Schwarzschild radius.

The Borderland of Sol

It is one of the earliest works of fiction to feature a black hole.

Black Hole Creek

Plants in the riparian buffer include speckled alder, which was placed there by the Black Hole Creek Watershed Association, and Lobelia cardinalis, which grows there naturally.

C.A.F.B.

With the help of Benedek Fliegauf C.A.F.B. has been booked in the legendary alternative rock club "Black Hole" the first time ever in the summer of 1991 which helped the group move forward and get noticed in the Budapest punk scene.

D-brane

The Bekenstein entropy is proportional to the black hole mass squared; because the Schwarzschild radius is proportional to the mass, the Bekenstein entropy is proportional to the black hole's surface area. In fact,

Kerr–Newman metric

In 1965, Ezra "Ted" Newman found the axisymmetric solution of Einstein's field equation for a black hole which is both rotating and electrically charged.

Lyrik

He has cooperated with renowned international DJs and producers like Tiësto, Paul Oakenfold and was signed by their labels "Black Hole" and "Perfecto".

Magnetospheric eternally collapsing object

Astronomer Rudolph Schild claims to have found evidence of such a magnetic field from the black hole candidate in the quasar Q0957+561.

Micro black hole

For sufficiently small M, the reduced Compton wavelength (\scriptstyle{\lambda \; = \; \hbar/Mc} , where ħ is Reduced planck constant) exceeds half the Schwarzschild radius, and no black hole description exists.

Sagittarius A*

The comparatively small mass of this black hole, along with the low luminosity of the radio and infrared emission lines, imply that the Milky Way is not a Seyfert galaxy.

Star Voyager

However, the game is lost if the enemy fleet reaches the CosmoStation Noah, the player enters the black hole, the player's ship runs out of fuel crystals, or if life support fails.

Sudhansu Datta Majumdar

While work continued on understanding these solutions better, a renewed interest in this metric was generated by the important observation of Israel and Wilson in 1972 that static black-hole spacetimes with the mass being equal to the magnitude of the charge are of Majumdar–Papapetrou form.

Swift Gamma-Ray Burst Mission

March 28, 2011: Swift detected GRB 110328A, which subsequent analysis showed to possibly be the signature of a star being disrupted by a black hole or the ignition of an active galactic nucleus.

The Hunters Club

The band were named after a short-lived Judge Dredd sub-plot in the sci-fi comic 2000 AD, and were nicknamed "The Black Hole of Rock 'n' Roll".

The New Biographical Dictionary of Film

Thomson notes that Clark Gable was a rising star at thirty: “Now, in our collective recollection, Gable may seem older, worldlier, and more grown-up than Cruise was at thirty. But when did Gable ever risk playing the jerk to whom Cruise was totally committed in The Color of Money? When was Gable as uninhibitedly tender as Cruise managed in Risky Business? And could Gable have survived the black-hole narcissism of Dustin Hoffman in Rain Man?”
