What is the difference between blackholes and wormholes?

A Black hole is a Quantum Singularity in which so much matter energy, be it solid, liquid, gas, or particle matter evaporated states are attracted to it through the quantum gravitational attraction, and once they enter into the singularity those states are crunched into a quantum compressed state in which matter energy will exist with absolutely no function, and the quantum gravity state is so strong nothing at all, not even light quanta can escape this state so long as it remains stable.\n\nAlso nothing at all can travel through a Black hole it is a supper solid mass, which will crunch any, and everything which enters it, if you here that it is a gateway to another universe, or you can pass through it, the person telling you this is probably watching to many Disney movies.\n\nA worm hole is completely different state of function, and actually folds space with respect to an energy vortex which I believe occurs naturally under specific conditions, and can also be created, however no person has created one to my knowledge at this time, with respect to this time line which we are now living in, and observing, although if they have then I feel positive that it would be labeled top secret, and we would know be the wiser to that knowledge.

Curved spacetime.\n\nThere is nothing unduly special about the event horizon (ie it has no discontinuities). And very large black holes do not have unduly curved spacetime at their event horizons (the curvature of the supermassive black hole at the centre of our galaxy is on 20 times greater than that here on Earth, and here on Earth the curvature is pretty much undetectable).

Not really, a solid is usually atoms packed closely enough together so that they bond and form a structure that is resistant to change. Blackhole cores are of collapsed matter: there are no atoms, protons or even quarks. Just like plasma isn't "gas," blackhole material isn't solid

A black hole is a place where the escape velocity is greater then the speed of light because the object's gravity is so strong.  Since nothing is known that can go faster then the speed of light, anything falling into a black hole can never get out, hence the name "black hole."  What happens inside a black hole is not known.  The center of a black hole is theorized to be a singularity because it is a point where all the black hole's mass is squeezed to a point of infinite density.  We really don't know for sure what happens in a black hole because our current theories are not complete, and the fact that no information can ever leave a black hole.  While nothing can escape into a black hole, we can detect them because as things fall into them, they heat up and give off x-rays before they make the plunge.\n\nTwo types of black holes are known to exist.  One is formed when an extremely massive star dies, and it's core is so massive and small that it collapses under its own gravity to become a black hole.  Another type are called "supermassive black holes" which seem to exist in the center of every galaxy (that means our own too).  How or why these black holes formed nobody really knows.  It probably goes back to how galaxies formed in the first place, although we don't know that either.

extremely condensed matter.\n\nBlack holes have an even greater density than nuclei or neutron stars. Their volume can be approximated with the Schwarzschild radius.

I'm not sure I understand the question.  However, newton's laws of gravitation do not describe anything like black holes.  Black holes fall out of Einstein's theories of general relativity.

A black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it except through quantum tunnelling behaviour (known as Hawking Radiation). The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can let one exit a black hole. The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return.\n\nThe existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei.\nContents\n\nHistory\n\nThe concept of a body so massive that not even light could escape it was put forward by the English geologist John Michell in a 1783 paper sent to the Royal Society. At that time, the Newtonian theory of gravity and the concept of escape velocity were well known. Michell computed that a body 500 times the radius of the Sun and of the same density would have, at its surface, an escape velocity equal to the speed of light, and therefore would be invisible. In his words:\n\nIf the semi-diameter of a sphere of the same density as the Sun were to exceed that of the Sun in the proportion of 500 to 1, a body falling from an infinite height towards it would have acquired at its surface greater velocity than that of light, and consequently supposing light to be attracted by the same force in proportion to its vis inertiae (inertial mass), with other bodies, all light emitted from such a body would be made to return towards it by its own proper gravity.\n\nAlthough he thought it unlikely, Michell considered the possibility that many such objects that cannot be seen might be present in the cosmos.\n\nIn 1796, the French mathematician Pierre-Simon Laplace promoted the same idea in the first and second edition of his book Exposition du Systeme du Monde. It disappeared in later editions. The whole idea gained little attention in the 19th century, since light was thought to be a massless wave, not influenced by gravity.\n\nIn 1915, Einstein developed the theory of gravity called General Relativity. Earlier he had shown that gravity does influence light. A few months later, Karl Schwarzschild gave the solution for the gravitational field of a point mass, showing that something we now call a black hole could theoretically exist. The Schwarzschild radius is now known to be the radius of the event horizon of a non-rotating black hole, but this was not well understood at that time. Schwarzschild himself thought it was not physical.\n\nIn the 1920s, Subrahmanyan Chandrasekhar argued that special relativity demonstrated that a non-radiating body above 1.44 solar masses, now known as the Chandrasekhar limit, would collapse since there was nothing known at that time that could stop it from doing so. His arguments were opposed by Arthur Eddington, who believed that something would inevitably stop the collapse. Both were correct, since a white dwarf more massive than the Chandrasekhar limit will collapse into a neutron star. However, a neutron star above about three solar masses will itself become unstable against collapse due to similar physics.\n\nIn 1939, Robert Oppenheimer and H. Snyder predicted that massive stars could undergo a dramatic gravitational collapse. Black holes could, in principle, be formed in nature. Such objects for a while were called frozen stars since the collapse would be observed to rapidly slow down and become heavily redshifted near the Schwarzschild radius. The mathematics showed that an outside observer would see the surface of the star frozen in time at the instant where it crosses that radius. However, these hypothetical objects were not the topic of much interest until the

yes it do.\n\nIn physics, a wormhole (also known as Abbreviated Space) is a hypothetical topological feature of spacetime that is essentially a "shortcut" or "abbreviation" through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat.\n\nThe name "wormhole" comes from an analogy used to explain the phenomenon. If a worm is travelling over the skin of an apple, then the worm could take a shortcut to the opposite side of the apple's skin by burrowing through its center, rather than travelling the entire distance around, just as a wormhole traveller could take a shortcut to the opposite side of the universe through a hole in higher-dimensional space.\n\nThere is a compact region of spacetime whose boundary is topologically trivial but whose interior is not simply connected. Formalizing this idea leads to definitions such as the following, taken from Matt Visser's Lorentzian Wormholes:\n\nIf a Lorentzian spacetime contains a compact region Ω, and if the topology of Ω is of the form Ω ~ R x Σ, where Σ is a three-manifold of nontrivial topology, whose boundary has topology of the form dΣ ~ S², and if furthermore the hypersurfaces Σ are all spacelike, then the region Ω contains a quasipermanent intra-universe wormhole. \nCharacterizing inter-universe wormholes is more difficult. For example, one can imagine a 'baby' universe connected to its 'parent' by a narrow 'umbilicus'. One might like to regard the umbilicus as the throat of a wormhole, but the spacetime is simply connected.\n\n\n\nIntra-universe wormholes connect one location of a universe to another location of the same universe(in the same present time). A wormhole should be able to connect distant locations in the universe by bending spacetime, allowing travel between them that is faster than it would take light to make the journey through normal space. See the image above. Inter-universe wormholes connect one universe with another [1], [2]. This gives rise to the speculation that such wormholes could be used to travel from one parallel universe to another. A wormhole which connects (usually closed) universes is often called a Schwarzschild wormhole. Another application of a wormhole might be time travel. In that case it is a shortcut from one point in space and time to another. In string theory a wormhole has been envisioned to connect two D-branes, where the mouths are attached to the branes and are connected by a flux tube [3]. Finally, wormholes are believed to be a part of spacetime foam [4]. There are two main types of wormholes: Lorentzian wormholes and Euclidean wormholes. Lorentzian wormholes are mainly studied in semiclassical gravity and Euclidean wormholes are studied in particle physics. Traversable wormholes are a special kind of Lorentzian wormholes which would allow a human to travel from one side of the wormhole to the other. Sergey Krasnikov tossed the term spacetime shortcut as a more general term for (traversable) wormholes and propulsion systems like the Alcubierre drive and the Krasnikov tube to indicate hyperfast interstellar travel.

you're thinking of a worm hole. a black hole will, as far as we know tear things apart to as it takes them to a different part of our universe, which doesnt make sense because nothing can escape from them. Anyway, a worm hole, which is theoretical -mostly- is like two black holes connected at their vertex's. think of the universe as a thin sheet of paper. one black hole is is on the right side, and another on the left. fold the piece of paper so that the black holes are lines up. instead of traveling from point A to point B, you just go through space in manner of speaking from point A to point B "just like that". there really isnt any just like that, but that's as best i can describe it with out actually showing you. sorry if this makes no sense.

Wormholes, Alcubierre Drive.  Wormholes are predicted in general relativity and quantum mechanics, the thing is that no one's found one yet and even if we did we wouldn't know what to do with it.  Alcubierre warp drive is an interesting idea, but there's no way to do it yet.  It involves warping spacetime such that the space behind you pushes you forward faster than the speed of light.

A black hole is an immensely massive (dense, heavy) and immensely small (tiny) object in space that has such a strong electromagnetic and gravitational pull, it sucks light photons into it, making it look like there is a giant hole in the universe.\n\nNothing anywhere on this planet, including in the ocean, is anything like a black hole.

The comment about a worm hole (or warping for that matter) is only partially true.  The object that travels through a worm hole or a space warp still can only travel (assuming it has a mass) at the speed of light through that worm hole or space warp.  It only "appears" to travel much faster than that from an "observer" not in the worm hole or warp.\n\nThe difference is the "effective" speed can be much faster than light; however, the object can only travel the speed of light.\n\nAn example; lets say that you have a car that travels at 100 mph (~160 km/hr) and you "created" a worm hole (or space warp) to travel from New York to LA.  You would still only drive at 100 mph, but the travel time form NY to LA would be fractions of a second thus for an observer from say Dallas would "see" your car one moment in NY and a faction of a second later "see" your car arrive in LA.\n\nFor people that might not understand a worm hole is like folding the map of the US in our example and if you can "fold the map" in the right way such that NY and LA are right on top of eachother it would only take a fraction of a second to travel from NY to LA in your car.

Their existence has been postulated, but more often in science fiction than in actual science.  Some suggest that quasars (which are extremely bright) are actually white holes, and that white holes are possibly connected to black holes via wormholes.  But white holes seem to violate the second law of thermodynamics, and therefore probably do not exist.

First a black hole is a point of infinite density where gravity is so strong that even light cannot escape. A white hole is a hypothetical point of negative gravitational energy that emits matter from it. By negative gravitational energy i mean this: A planet has positive gravitational energy because it pulls matter towards its center of mass and experiences normal everyday gravity, but a white hole, which has negative gravitational energy is the exact opposite, it repels matter and nothing, not even light can reach the surface of a white hole. A wormhole is a hypothetical shortcut in the fabric of space and time. Think of it like a blanket that you are trying to get across, the simplest way to cross it is to just follow its surface in a straight line. A worm hole on the other hane is like folding the blanket in half and cutting a hole in it and going through that hole which is a much much shorter and quicker way of moving long distances.

I-LIKE-A-DA YO-YO!!\n\nshort version:\n\nneutrons & protons have arcs of electricity between them. or, "strings"\n\nstrings sometime break off and just disapear.\non occasion, a rouge string will become a worm hole (about a 20-25% chance)\nvery rarely, a wormhole will become a "membrane" or a small pocket of energy. (4-8% chance from worm hole stage)\n\nthe thoery is that these membranes, or "branes" for short(mem"brane"), colected together to eventualy form a bubble of energy the size of a universe. and that two of theses monsters slamed into each other to create the "big bang" theory we know today.\n\nyep, still a nerd.\n\nStargazer.
