  2. Black hole - Wikipedia

    en.wikipedia.org/wiki/Black_hole

    A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...

  3. Gravitational singularity - Wikipedia

    en.wikipedia.org/wiki/Gravitational_singularity

    While in a non-rotating black hole the singularity occurs at a single point in the model coordinates, called a "point singularity", in a rotating black hole, also known as a Kerr black hole, the singularity occurs on a ring (a circular line), known as a "ring singularity". Such a singularity may also theoretically become a wormhole. [18]

  4. Gravitational wave - Wikipedia

    en.wikipedia.org/wiki/Gravitational_wave

    Such particles include the gluon (carrier of the strong force), the photons that make up light (hence carrier of electromagnetic force), and the hypothetical gravitons (which are the presumptive field particles associated with gravity; however, an understanding of the graviton, if any exist, requires an as-yet unavailable theory of quantum ...

    A black hole is an area with such strong gravitational pull that nothing, not even light, can escape the hole's grasp. The team turned the telescope toward a hot cloud of dust and gas swirling ...

    Slow motion computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during 0.33 s of its final inspiral, merge, and ringdown.The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as spacetime itself is distorted and dragged around by the rotating black holes.

    The sequence of images dating from 2009 to 2017 have been put together as a .gif that shows the activity and "wobble" of a black hole. How does a black hole move? A new video gives us our first ...

  8. Negative energy - Wikipedia

    en.wikipedia.org/wiki/Negative_energy

    The negative-energy particle then crosses the event horizon into the black hole, with the law of conservation of energy requiring that an equal amount of positive energy should escape. In the Penrose process , a body divides in two, with one half gaining negative energy and falling in, while the other half gains an equal amount of positive ...

  9. Introduction to general relativity - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_general...

    There are several properties that make black holes the most promising sources of gravitational waves. One reason is that black holes are the most compact objects that can orbit each other as part of a binary system; as a result, the gravitational waves emitted by such a system are especially strong.
