  • As far as I know, nothing escapes their gravitational pull.
  • Yes. It's called "Hawking radiation" Here's one link. Google will turn up many more. http://en.wikipedia.org/wiki/Hawking_radiation
  • Until the mid-1970s most physicists would have confidently answered "no" because light cannot escape a sufficiently large gravitational field. Then Stephen Hawking showed how black holes, no matter how massive, had to emit some radiation due to quantum effects. Black holes are slightly brown!
  • In a word, yes. Black holes slowly decay over time, shooting off a single electron at long intervals.
  • Black holes occasionally emit x-rays when they absorb something, and there's the Hawking Radiation theory.
  • Black holes are some of the most radiant objects in the Universe. Quasars, for example, the brightest objects visible, emitting the light of thousands of galaxies combined, are thought to be supermassive black holes. Infalling matter into black holes create what are called accretion discs. These accretion discs cause the matter to heat up to tremendous energy levels. Accretion is actually more efficient at converting matter to energy than fusion -- the energy souce of stars -- and much of that energy goes shooting off into space in great geysers of highly energetic radiation. For more information on this phenomenon, see: http://en.wikipedia.org/wiki/Accretion_disc
  • I don't think so. Blackholes must absorb radiation. Radiation too is a form of energy like light energy.
  • There are a lot of astrophysicists arguing the details ... some say the black hole itself is not actually emitting any, but the very near surrounding area is, so since the radiation is coming from all around the edges of the black hole, it appears as though it is the hole that is radiating ...
  • "A black hole is a region of space in which the gravitational field is so powerful that nothing, including electromagnetic radiation (e.g. visible light), can escape its pull after having fallen past its event horizon." http://www.answerbag.com/q_view/1187912#add_answer_box
  • No. The gravity inside a black hole is so strong, time and light stand still, things go in, but never come out. The radiation we witness in the form of jets around the black hole in and around the event horizon do emit radiation.
  • Hawking radiation, also known as Bekenstein-Hawking radiation is a thermal radiation with a black body spectrum predicted to be emitted by black holes due to quantum effects. http://www.astro.uu.nl/~strous/AA/en/antwoorden/zwarte-gaten.html
  • Short Answer "Yes" Have a look at what info I found.. heres the link its very interesting and kinda scary considering we have a similar black hole in the milky way... Maybe this is what happens when a Black Hole gets to the maxium effect of its gravitational pull. A Burp... (: http://www.washingtonpost.com/wp-dyn/content/article/2007/12/17/AR2007121701266.html
  • Yes it is called Hawking radiation also known as Bekenstein-Hawking radiation, is a thermal radiation with a black body spectrum predicted to be emitted by black holes due to quantum effects. It is named after the physicist Stephen Hawking who provided the theoretical argument for its existence in 1974, and sometimes also after the physicist Jacob Bekenstein who predicted that black holes should have a finite, non-zero temperature and entropy. Regards.
  • No. Hawking Radiation originates near the event horizon of a black hole, but not from the black hole itself... which is far beneath the event horizon. Anything that falls within the event horizon doesn't escape from the black hole.
  • Black hole and Big bang. 1. A black hole is a theoretical region of space in which the gravitational field is so powerful that nothing can escape. 2. Hawking Radiation theorizes that black holes do not, in fact, absorb all matter absolutely; they give off some return matter. 3. Once upon a time, 20 billions of years ago, all matter (all elementary particles and all quarks and their girlfriends- antiparticles and antiquarks, all kinds of waves: electromagnetic, gravitational, muons… gluons field ….. etc.) – was assembled in a ‘single point ‘ The reason of this unity is gravitational force. 4. How does this ‘single point ‘ created if the matter can escape from any strong gravitational force? ==========.. http://www.physforum.com/index.php?showtopic=2548 http://www.wbabin.net http://www.socratus.com
