CERN is an official United Nations Observer. Israel is the only non-European country granted full membership. Established in 1954, the organization is based in a northwest suburb of Geneva on the Franco–Swiss border and has 23 member states. “Black holes are where God divided by zero.The European Organization for Nuclear Research ( French: Organisation européenne pour la recherche nucléaire), known as CERN ( / s ɜːr n/ French pronunciation: derived from the name Conseil européen pour la recherche nucléaire), is a European research organization that operates the largest particle physics laboratory in the world. ![]() One of the cool results (results, not assumptions) of this theory is that space-time is fundamentally discrete (at a very small scale)! This is a radical shift from how we normally think of space and time, and is likely to help us address a host of current problems in theoretical physics. This theory is called “loop quantum gravity” or “quantum geometry” and it is showing lots of promise. And we are trying to answer these types of questions in the context of that theory. I actually work on an approach to quantum gravity myself (with collaborators, of course) - one that is less ambitious and less radical when compared with String Theory. The only thing that has come close, is String Theory, but that too has major issues of its own. Its over 60 years old and even individuals like Einstein and Feynman have tried their luck at it - with no success. Now, the problem of “quantum gravity” as needed here, is a big open problem in theoretical physics. The hope is that if we correctly incorporate both gravitational and quantum physics concepts - we wouldn’t have this problem. We actually know why we encounter this problem - we even expected it! The reason is that in this picture we’re ignoring the Physics of the small i.e. In addition, if you added more matter into the hole, it would also eventually settle in with the interior singularity! This is the root cause of why our understanding of the interior structure of black holes is stuck. When the simulation would reach that infinitely dense state, the numerics would simply fail because they wouldn’t be able to handle a genuine, physical, infinity. Imagine you had a computer simulation crunching the numbers that follow the process of gravitational collapse. This infinity is also the reason that we can’t tell what happens next. So, what is the end result of such a process? It would have to be a mathematical infinity - because it would eventually end up as a point (zero-size) with all that mass - the physical density (mass per unit volume) would literally be infinite! And we don’t think that Nature has real infinities floating around, so we know that is a serious problem in our understanding. Nothing can stop this gravitational collapse. In simpler words, because gravity is so strong for a such a compact object, it has to keep collapsing under its own weight - indefinitely. a black hole has formed) it can be proved that the matter has to keep getting compressed indefinitely. become dense enough) that an event horizon has formed around it (i.e. The reason for this infinity is that once matter has collapsed enough (i.e. The problem with the black hole interior, is that it contains a mathematical singularity or an infinity. However, if you want to stick to what is generally accepted by physicists, here goes. This opens the doors for a lot of speculative ideas, including what what Kai mentioned. As far as the question of where the matter that a hole swallows goes, it is not completely understood because the interior of a black hole itself is not completely understood. What Kai has described so far is pretty accurate. > continuum and bring two universes in contact. > the strength of the field energy enough to collapse the space-time > matter just appears for no apparent reason) or into a parallel universe, > another part of our universe (which would be a white hole, a place where > say an arm chair was sucked in, where would it go? > even at that, where does the matter go that gets sucked in? let’s > millionth of an inch across with about as much gravitational pull as a ![]() > alone an arm chair in the office of the observer, for they are only a ![]() > black holes this machine could create cannot gobble galaxies, let > cannot actually obtain any matter around it, then it burns out. > So, if a black hole is so small that during its brief existence it > it must acquire mass … else, it collapses … Black holes may exist where a highly dense organization of mass is
