Does a void have colour? If not why do we say for a space term 'black holes'?

no, it does not. in physics, balck is not a colour. in the visible part of the electromagnetic spectrum, there is no black. a total absence of any colour is represented by black in physics. black holes are so named because they have such a strong gravitational force that they even attract light and do not allow it to escape. hence the name

something like what we call a "black hole"

A black hole is believed to be a neutron star that collapsed in itself because of extreme gravity. The gravity would get so strong that it forces even time and space into itself including light (that's why it's called black). Also associated with a "wormhole" and figured to be a portal to parallel universes or looped back to this universe in a different time, after the theory of the Einstein-Rosen-Bridge.\nI don't know if someone tried to measure the value of the gravity or if there is even a speculated formula but I don't think so.

Although black holes are not directly detectable, there is much indirect evidence of their existance such as the movement of other objects.\n\nGravity is not a simple phenomenon and cannot "escape" from anything. It is a property of space-time itself.

As science currently understands the voids you describe, they result from conditions in the very early universe when unequal densities of energy at quantum levels first formed. They are NOT related to explosions.

I suppose the answer is ultaviolet but as it is outside the visual spectrum of elctromagnetic radiation I can't see how you could define it as a coloUr.

Einstein conjectured on the existence of wormholes that connects two points of singularity in space-time, one being a blackhole that draws in matter, the other being a whitehole that emits matter. White holes appear as part of the vacuum solution to the Einstein's field equations describing a wormhole. While this gives the impression that black holes in this universe may connect to white holes elsewhere, this turns out not to be the case for two reasons. First, wormholes are unstable, disconnecting as soon as they form. Second, wormholes are only a solution to the Einstein field equations in vacuum (when no matter interacts with the hole). Real black holes are formed by the collapse of stars, where the infalling stellar matter is added to the black hole's history.

I believe there are two kinds of black holes. One I'm sure everyone will explain to ya, a great mass so large that light can't even escape it's gravity. But the other kind is theoretical: What if everything in THIS universe came from somewhere else? That is the only way I can explain it, except that somehow we are all headed for it again, to be sucked into it and expel ed into another place which right now is completely void, and this universe would be turned inside-out again.

Could not find a word to fit the gaps however found this website which might help.\n\nhttp://www.engr.mun.ca/~ggeorge/astron/blackholes.html\n\nP.S. The Doppler effect actually affects frequency so can be observed in sound, LIGHT and electromagnetic radiation.

Quarks outnumber protons because protons are composed of quarks; it is similar to asking why feet outnumber miles, or meters outnumber kilometers. \n\nAntimatter (And matter for that matter-lol) ceases to have any meaning in black holes because they are regions of space where matter is compacted to infinite density, thus having zero area. It can be said that black holes are made of nothing in the same way they are made of something.\n\nIn fact, any antimatter brought in contact with a black hole would simply be pulled in with anything else you throw at it; it's sorta like a starving dog when you throw dish towel and a piece of steak at it: neither will remain.

Not much actually as we still don't really have a clue what black holes actually are.\nThere are many questions to ask about the greenness of the black hole.. First, if the light is coming from the black hole itself then we actually don't have any black holes and everything we thought about them was wrong. \nScience is the art of guesswork based on what we already know. The term for this is called EMPIRICAL Science. Basically everything we are aware of is explained in this way.. When we make new laws or decided a black hole is a black hole, we are only guessing according to what we already know. \nIf you remember, people thought the world was flat, based on what they knew at that time. \nAnd the zeroth law of thermodynamics is called the zeroth because they had already come up with the first ,second and third before they realised they'd missed one..\nThe good thing about this is that essentially, this makes you just as smart as any of the top scientists in the world. Sadly, most of them would not share this point of view!!!!!

Space doesn't exist. There are things IN space. Matter makes up the stars and planets and gasses and eveything you see. Everything you DON'T see, I.E. the large black void, is nothing. There is no matter or antimatter or anything there. It's just....emtpy. Therefore, it doesn't exist. Only the things in it exist.

Things that enter a black hole do not "implode," and black holes and the big bang are two uttern non-connected things.\n\nshort answer day!

A black hole is a spacial anomalie with an extremely high gravitational mass, and supercondenses matter into an infinitismally small singular. If all the matter in the universe could be condensed into a ball the size of a speck of dust, then the size of the ball inside a black hole would be a fraction of a fraction of that, too small to see with the most powerful microscope on planet Earth. The hole however is much different, similar to a funnel. So at different points in the hole the size measurement is different. There is no actual hole however, more like a bend in the fabric of space, so nothing ever actually leave the universe, only changes density, form and location, among other things.

Another name for a black hole is "Quantum Singularity"\n\nAll the matter in the black hole has collapsed under its own weight to an infinitely small point. (there's the clue)\n\nAn infinitely small point would have no Length width or depth.\nAs time ceases from our perspective, once inside the event horizon, there is no time.\n\nHence a black hole is dimensionless no space/no time.\n\nWell that's how I see it anyway!!\n\nLet the argument rage on

Yes, it would be black. The colour of object depends on what wavelengths of light are absorbed and which are reflected back by an object essentially.\n\nSo if all wavelengths of light are absorbed then it appears black, and if everything is reflected then it appears white. Every other colour we see depends again on the wavelength that is reflected.
