Thanks Gals, and Your welcome :) Black holes do NOT exist and the Big Bang Theory is wrong, claims scientist - and she has the maths to prove it Scientist claims she has mathematical proof black holes cannot exist She said it is impossible for stars to collapse and form a singularity Professor Laura Mersini-Houghton said she is still in 'shock' from the find Previously, scientists thought stars much larger than the sun collapsed under their own gravity and formed black holes when they died During this process they release a type of radiation called Hawking radiation But new research claims the star would lose too much mass and wouldn't be able to form a black hole If true, the theory that the universe began as a singularity, followed by the Big Bang, could also be wrong http://www.dailymail.co.uk/sciencetech/article-2769156/Black-holes-NOT-exist-Big-Bang-Theory-wrong-claims-scientist-maths-prove-it.html |

Anyway, I came across this thread from the start of it and skipped from to the most recent page without reading the rest. I will return back to reading through the rest of it a little later on. You know, this thread really is about the notion that black holes now are not supposed to be existing at all. Who is supposed to be making this claim? Surprisingly enough, it is Stephen Hawking himself. But on the other hand, if we should believe nuclear physiscists correctly, the world as we see it is not as simple and straightforward as we are thought to believe. Rather, what we are seeing is the result of very complex processes and their possible mutual interaction with each other. Our own perception of the Universe is initially based on what we are able to see, next, what we may be able to learn by carrying out research on different subjects being of interest. This kind of research is what the responsibility of scientists is to carry out and therefore this is also what science and being a scientist is supposed to be all about. By carrying out investigative research in one or more subject fields, results are supposed to be obtained as a result of this work. In most cases what is being learnt is supposed to be accepted by other researchers despite possible competition and different opinions. In some other cases such results either are being rejected or even may become ridiculed. To astronomers and cosmologists, galaxies and galaxy clusters are assumed to be the largest known structures in the Universe. To nuclear physicists, the electron is still being regarded as being a single elementary particle together with other particles which are known to be exhibiting particular properties, thereby making scientists able to put these particles into different orders and contexts based on their individual properties. Neither galaxies and galaxy clusters as well as electrons may be possible to tell the whole story. Black holes is all about mass in huge amounts. Other than that we only surmise that gravity becomes tremendous and that light is unable to escape when getting inside the event horizon. The center of the black hole is supposed to be the singularity in which all aspects regarding time and space becomes lost and what may even be gravity becomes nothing at all. We may be wondering what our own role is in all of this and what the purpose and meaning is behind what is both within as well as beyond our current notion of things as they are supposed to be. |

I'll bet her math is flawed somewhere. Possibly, and possibly not... ;-) That all depends on what assumptions are made. Also, everyone always seems to forget about the effects of time... There may well be no 'singularities' in our universe in that there is not enough time for any to form. Note how the old description for a black hole was that of a "frozen star". That is an assumed star so massive that by its very own gravity, time appears so slowed as to be frozen. Hence, as a large mass collapses in on itself due to gravity, by that very same gravity time slows to slow the apparent collapse. You then get the competing effects of how quickly the mass evaporates across the event horizon and also for how quickly the surrounding universe evolves in the meantime... All a question of time?

I think we are like a group of ants residing on a few bricks on the side of a large mansion trying to describe their universe based on the immediate surroundings. This is not a new revelation, I borrowed it from the TV series Babylon 5. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required.

Black holes is all about death and destruction. They are the remnants of giant or supergiant stars which ended their lives in a spectacular show of light and energy which is called a supernova explosion. Unlike creation, thought of or assumed by astronomical terms to be about the Big Bang (a separate topic) and the following or ensuing inflation of the Universe, black holes are immense gravitational fields located in space where time is known to be coming to a standstill. The notion of time is a subject which is hard for some scientists to comprehend. We are seeking to understand things as they are by means of quantizising them or defining constants where possible, like the Planck constant. Our current notion or knowledge of the space-time world is at least a four-dimensional one. Some scientists are speaking of maybe a total of 11 existing dimensions rather than the currently accepted four. Also the point (or singularity) is one particular place in space, together with the three dimensions that make up for example a dice, or a cube of ice. Unlike a circle, which is a two-dimensional object, an object like a moon, planet, or star is a globe or the similar. Similarly a globular cluster is an aggregation of old stars having a shape like a globe, but containing many thousands of stars. Gravity is the main reason for the existence of three-dimensional objects in space. Time is supposed to be a movement of one or more of the three known dimensions through a thought of or assumed "hyper-space" which is at least four-dimensional, possibly even more, like the mentioned 11 or so. According to Stephen Hawking, black holes are not supposed to be existing at all. Our current notion or knowledge of God is a result of religious beliefs and traditions, not as a result of so-called unexplained events and other similar phenomena. Science is supposedly best carried out by means of being either an agnostic or atheist. Some people end up being skeptics or even debunkers. They are still thought of as being scientists, though. In the end you are supposed to be doing a superb job, regardless of your personal attitude and behavior. Our current knowledge of science is all about our knowledge of different and certain subjects. Books and other presentations about the Universe which is all around us, whether or not it being micro-cosmos or macros-cosmos, is presenting material based on the way our current knowledge has been obtained by means of scientific scrutiny and analysis. One such example is the current knowledge about the material which is known to be existing or composed in different stars and therefore is known to be present in such objects. Stars are everything from white, red and brown dwarfs through main sequence stars, giant stars and supergiant stars. Some of these objects end up their lives as novae (double stars systems with mutual interaction between the stars), supernovae of at least two different two types or categories and in the end the more exotic objects like neutron stars and the black holes themselves. Gravity was discovered when renowned physicist and astronomer Isaac Newton was sitting below a tree and was hit in the head by an apple falling down on him. In the vicinity of a black hole everything is being sucked into it because of its gravity. After entering or bypassing the event horizon, assumedly consistent or equal to the Schwarzschild radius, which is the place in space where neither mass nor light escapes and time comes to an almost standstill, incoming material ends up in the black hole itself, becoming crushed to either nothing or at least only the most elementary particles with no radiation at all being present. The black hole is supposed to be having a singularity at its core. The singularity is a "point in space" where all our current knowledge of space and time and the laws posslbly related to the same ceases to exist. If not a Newtonian, or even Einstein-based Universe, Quantum Theory is trying to give an understanding of events related to micro-cosmos and not necessarily macro-cosmos. Micro-cosmos is all about the speed of particles in a possibly hyper-dimensional field which is directed by the presence of gravity. But in a black hole everything is assumed to be coming at a stand-still with nothing happening at all. It is a totally dead place. So why bothering about such objects like black holes and rather not starting about thinking about evolution and creation instead? Being an agnostic or atheist makes it hard to define one or more Gods in all of this. The subject of science is all about doing good science - not about whether or not we should be able to belive in the existence or precence of God at all. In the end we are in fact living here where we are. We are able to do things both for the good and the bad. We know what happened in the past, but we are still not able to know what will be happening tomorrow, or the day after. |

Big black holes can block new stars Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found. The research provides crucial new evidence that it is these jets of “radio-frequency feedback†streaming from mature galaxies’ central black holes that prevent hot free gas from cooling and collapsing into baby stars. http://www.astronomy.com/news/2014/10/big-black-holes-can-block-new-stars |

Are quasars (super massive black holes) actually aligned along cosmic filaments of dark matter? This is what scientists are now looking at after receiving fresh data gathered by the Very Large Telescope. http://www.news.com.au/technology/science/scientists-detect-an-eerie-alignment-of-black-holes-suggesting-an-underlying-dark-matter-filament-to-the-universe/story-fnjwlcze-1227128976918 Cheers. |

weird little fella. Potential Black Hole Discovered 2,600 Light Years from Its Galaxy’s Core A team of researchers has used data collected by NASA’s Swift satellite, the W. M. Keck Observatory and the Pan-STARRS1 telescope to locate, what appears to be, a black hole that has been ejected from the core of its host galaxy. http://www.viralglobalnews.com/science/potential-black-hole-discovered-2600-light-years-galaxys-core/24003/ |

Could orphan black hole confirm Einstein's general theory of relativity? Scientists believe a mysteriously bright object in a galaxy 90 million light-years away could be a rogue black hole evicted during the merger of two galaxies. Astronomers have long hunted for galaxies that might be evicting supermassive black holes at their centers. Eviction would represent an important confirmation of Einstein's theory of general relativity under extreme conditions and could help shed light on the influence such massive features have on the evolution of galaxies themselves. http://www.csmonitor.com/Science/2014/1121/Could-orphan-black-hole-confirm-Einstein-s-general-theory-of-relativity |
