Can naked singularities and quantum black holes coexist in the same universe?
Pasha582
We have never had an opportunity to study a quantum black hole, which theories predict ought to exist. "Naked" singularities - places where the laws of physics seem to break down, but without an "event horizon" - are currently mathematical abstractions. They may not be possible.
However, the concept of a "singularity" is simply a statement that our current theoretical models of reality are incomplete, and that WE DO NOT KNOW what will happen. I expect that as we gain more knowledge, we will discover one or several tiny facts that change the way we view the universe, and will make it possible for us to understand it.
Keep an open mind; the universe is stranger than we imagine.

Does this universe exist within a black hole?
Most scientists don't think so. The reason the question isn't patently ludicrous is that a) physics doesn't really say much about what's inside the event horizon of a black hole, and b) the radius of the event horizon scales directly with mass for black holes. So the larger a black hole is, the lower its average density is. Galactic-mass black holes can have surprisingly low densities (again: on average; at the singularity, density is infinite). It turns out that if you plug a reasonable guess for the mass of the observable universe into the equation for the Schwarzhild radius of a black hole, you get a radius of ... approximately the radius of the observable universe. Within a couple of orders of magnitude, anyway (and in cosmology, that's considered pretty close). So it's not as silly a question as it might appear at first. However, the reason we don't think the universe is inside a black hole is that a) the universe is expanding, which is hard to reconcile with it being inside a black hole, and b) it doesn't look like the universe has enough mass to halt the expansion (in fact, the expansion appears to be accelerating). There are a few, however, who do think it's possible. For some reason adding related links is not working, but do a Google search for "national geographic universe black hole" and you should find a recent (Feb 2014) article about it.
What band of radiation is best for studying black holes?
X-rays are the best band for studying black holes as the radiations emitted by the black hole is X-rays so we can expect the presence of a black hole anywhere in the Universe.
Was the Big Bang caused by a universe-sized black hole?
Theoretically yes. String theory and M theory says that when the two universe collide together or split into two universes, that is when Big Bang occurs. However there is no evidence that Parallel universe exists.
Is a black hole hot?
I will try to simplify the answer down to the black hole object itself, and I assume the question revolves around classic black holes and not quantum black holes (which may very well be the hottest hypothetical objects in the universe).It is insufficient to state that a black hole is simply "cold" or "hot", since black holes can be both - and only in extremes.A black hole attracts matter via. the immense gravitational pull, and as with anything to which motion is applied, heat is generated. While a black hole attracts matter the temperature will therefore bevery high, as the absorbed matter will reach incredible speeds while it enters the black hole, and the outer layer will reachenormous temperatures. In other words, the compression of the matter itself heats up the outer layer of the black hole to millions of degrees.It is a widespread misunderstanding that black holes do not emit radiation. While black holes are consuming matter,radiation, such as x-ray and gamma ray, will be emitted from the black hole. And this is in fact how we typically detect a black hole. You should also be able to observe the actual heat, as black holes will not be absolutely black while they are absorbing matter, and can potentially light up the surrounding objects.The biggest black holes however, may be the coldest objects in the universe, given there is no matter around them left to consume. This means that they will either emit little or no radiation at all, and the temperature will be only near a billionth of a degree above absolute zero.
Where are the singularities within black holes located?
It is thought that at the very center of a black hole is a quantum singularity.

Can black wildebeest coexist with blue wildebeest?
yes if they are in the same place.
What is singularities of big bang theory?
A singularity is a situation in which a certain mass (usually a large mass) is concentrated in ZERO volume, resulting in an infinite density. This can happen, in certain theories, for black holes, and as the initial conditions of the Big Bang. Physicists generally believe that such singularities don't really exist, and that, if singularities to appear in some formula, they represent a failure of the corresponding theory at extreme conditions.
What is an area of infinite density that traps even light?
They are called Black Holes or singularities.
When will a black hole hit your universe?
There are already black holes within the universe
What are black holes and are they real?
Black holes do exist. They are giant singularities (infinitely small compressed matter) that such pretty much everything in. They have been proven to exist and they are a very talked about subject in the field of astrophysics.
Were do black leopards live?
Black leopards live in the same habitat as regular leopards. Although more rare, black leopards coexist with their normal-colored counterparts.
Does the universe have a black hole?
The universe likely contains millions upon millions of black holes.

Is the universe being consumed by the galactic black holes?
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
