A black hole with the mass of the universe has a radius the size of the universe. Are we in a black hole?

Answer 1

We are not in a Blackhole. You know what will be the value of g if we arein a black hole and how much you will weigh.
But we are orbiting a BlackHole. SO we are under the influence of a blackhole

Answer 2

I think you mean: could we be within the event horizon of a black hole (which does have a definite radius). The answer is no. The "size of the universe" is not actually known -- all we can see are galaxies whose light has had time to reach us since the Big Bang (the "visible radius"). The actual radius of the universe could be much greater than this, and most cosmologists believe that it is.

Answer 3

No, a black hole is a lot more dense than the Universe. So it certainly doesn't have the same radius (i.e. size) as the Universe, which mostly consists of empty space.

Answer 4

"in accordance to the massive Bang theory the Universe has been increasing from a tiny length to its recent length." No. That changed into the unique hypothesis (The Primordial Atom hypothesis). the well-known theory has the boom originate in a state of unbounded power and density. in some unspecified time sooner or later interior the previous (the nearest we may be able to get to time=0), the temperature changed into so severe that each unmarried aspect of the universe ought to were a black hollow. That difficulty is the singularity (it does no longer advise that the universe changed into tiny). considering each aspect turned right into a black hollow, then it ought to were on the progression horizon of each neighboring black hollow. This makes all of them infinitesimal black holes (of an analogous length). in accordance to the idea behind Hawking radiation, you could imagine that they ought to evaporate very quick (and together), freeing all the ability they contain. The power drives the boom. Later, because the common power density diminishes (we may say "because the temperature cools down"), the forces separate, then the quarks, then count number kinds, then lots of the lighter factors are shaped (all that interior the first 3 minutes, as measured from our body of reference). Even we theory that the ability content fabric changed into consistent (in case you concentration on a volume increasing on an analogous fee because the universe, it ought to continually educate an analogous density of power -- such as in spite of power changed into switched over into count number and rigidity). even with the indisputable fact that, it ought to look that some thing is causing the boom to strengthen its fee. we do not understand what that's and we call it "darkish power" (darkish meaning 'unknown' in this context).

Answer 5

Isaac Asimov speculated on this years ago. If I remember correctly, he concluded that it possible, but we can't ever know, because we don't know the mass of the Universe, and therefore can't calculate its Schwarzschild radius. Although he was a brilliant Scifi author, he also had formidable credentials as a hard scientist, and wrote many articles dealing with scientific fact.

Answer 6

Black holes do not have radii. They are an infinitely small point in the fabric of space-time

Answer 7

duh..you can't have black holes inside black holes. black holes are formed by collapsing stars. if the star was in a blackhole it would already be collapsed. anyway that black hole exploded.

Answer 8

No and I recommend you stop watching SF nonsense or take a real science course.

Answer 9

Nope. If we were, all the galaxies would be moving towards each other, not further apart.

Answer 10

There is no way for us to determine that. Sorry
