What are the dimensions of a blackhole?

Answer 1

infinite, all expanding, unknown

Answer 2

AND the perfect answer IS.......... Blackholes aren't any further as black as you've been convey about trust. they have a temperature. that's punctiliously small and the more advantageous valuable the mass of the blackhole the smaller the temperature receives. (we are speaking 10 ^-6 deg Kelvin above absolute 0). Spontaneous particle creation in vaccuum defined with the help of the uncertainty theory (quantum outcome) leads to some debris falling into the BH at the same time as the equivalent and opposite particle escapes. Its those escaping debris that provide upward thrust to the delicate outflow of ability - its observed as Hawking radiation. Given sufficient time (10 ^88 years) a black hollow will evaporate. Now, if the black hollow is rotating then there is yet another mechanism for ability loss and that is the creation of gravity waves - they are though attempting to come across those. honestly the BH is so humongous that that's able to tug area and time round it because it rotates (its observed as body dragging, its only like stirring a cup of tea) and waves in area and time are produced that challenge out far flung from the BH - this reduces the BH rotational ability by technique of way of the years. One very very last component - for tiny tidgy little BH's (in direction of the end of the black holes existence with the help of Hawking radiation evaporation), at the same time as the type horizon is each and every of ways all the way down to the diameter of an atom, the Hawking radiation is so tremendous that the temperature of the BH will improve such that considered radiation is produced - so black holes can shine. If lets create such an merchandise it would want to correctly be an truly good ability source. merely correct needs LT

Answer 3

Black holes are really hard to find because they trap all the light and you might fall in. You will know when you are near one because things will start to look loooong and stretchy. To find the entrance throw some corn flour into the air and watch where it goes. Don't use grits because they won't float around like flour does. Measure the opening with a really really stiff ruler. It should be about thus and such Rods wide, more or less. To measure the depth you will need two stop watches. Put one in a copper wire frame shaped like an Archimedes pyramid. Keep that one and toss the other one in. Go to the other end, where you see the flour blow out and compare the times. The difference in milli-seconds divided by the logarithm of the diameter of the entrance, measured in Parsecs will give you the depth in Angstrom units.
I hope this was enlightening. Good luck on your trip.

Answer 4

there are no dimensions...

this might be difficult to understand but consider this:

Think about shrinking down the Sun into a marble. This marble would be like a black hole! It has so much gravity that light even get sucked in!

The actual dimensions cannot be measured. The center of a black hole is so small that we cannot see it. It is so small and dense that it sucks everything into it!

It is very hard to comprehend, but we are still studying black holes.

Answer 5

The theoretical dimensions of about a 2.5 solar masses star would be about 3 or 4 km diameter.
It is calculated by a formula that determines the surface orbital speed, a black hole would be the speed of light.

Answer 6

Yesterday the 24th I watched a program on the History channel about the 10 biggest threats to mankind/humanity as we know it. I believe black-holes was 5or6 on the list. Anyway on it it was stated they can be as small as a single atom. Which is very small, there are now over 100,000 known and charted by NASA and they keep a watch on them. Because.even though the closest ones are hundreds of light years away. Should one, even that small ever get close to earth, It would swallow everything on earth not nailed down.FYI. We are the NO.1 threat to ourselves.

Answer 7

at the event horizon, no way to be sure really. warping of space at that point makes prety much any measurement meaningless. all you can get is a rough estimate and in any case it is different for each one. now at the center/bottom the dimensions are known. 0x0x0cm that's why it's refered to as infinitely dense. now black holes that are spinning may not have a bottom so those dont count so.......yeah it's better just not to worry about it.

Answer 8

The only two dimensions that matter are mass and spin. The size of the event horizon depends on the mass.

Answer 9

Interesting question!

As I understand it - and there may be others who understand differently - is that a black hole has only one dimension (Which is why it is sometimes called a singularity)

The disk AROUND it is still in "normal" space and has three dimensions - which is how they decide how "large" a black hole is. But the hole itself has no meaningful "size" in our three-dimensional world.

THANKS!

Answer 10

Only matter that occupies space have dimension. Since its a hole and is literally nothing, it has no size and shape.

Answer 11

That depends on what you define as a black hole.. ideally and at perfection it would be a point singularity... or 0X0X0 dimension wise (in a 3D model)
