Is the pee hole the hole where you finger yourself?

No, the pee hole, also known as the urethra, is where urine exits the body. The vaginal opening is where fingers can be inserted for sexual pleasure.

What is special about Black Holes?

To many people, what is special about black holes is that they do not obey laws of physics, or gravity. The power is so great that it is hard to imagine. They literally bend space and time; they have such a big gravitational pull that the entire earth would be crushed to the size of a basketball. Think of all the things on our planet... minimized to the size of a basketball! Unfathomable, right? That's what most people think. Search "vsauce black holes" on youtube. He has got some pretty interesting things to say about them!

How can black holes bend light?

Imagine a big sheet. If you place a large object on it, it will bend. Imagine that the sheet is the space-time continuum, and the large object is a star. If, with our sheet model, you try to roll a marble past the object, it will at least curve its path, if not fall into the large object. The same applies to any object in space, even the photons of light. As they go past a star or other large object, they bend. I hope this helped.

Why wont your sun become a black hole?

The sun won't become a black hole simply because it lacks sufficient mass to make the transition. A black hole is formed when a giant star reaches a point where it collapses. There is a "threshold" or minimum amount of mass a star must have to become a candidate to become a black hole. Our neighborhood star is too "light" to make the cut.

The only way for our star to become a black hole is to randomly gain almost 10x its amount of matter. even then we need to wait another 5 billion years for it to go supernova, and even if that happened, there is still the chance it will become just a neutron star.

What thing is in black hole?

A black hole is a region in space where gravity is so strong that nothing, not even light, can escape. The "thing" inside a black hole is thought to be a singularity, a point of infinite density where the laws of physics as we currently understand them break down.

What is the typical size of hand hole?

The typical size of a hand hole in electrical and telecommunication applications is around 8 inches in diameter. This allows for easy access for maintenance and cable pulling while still being small enough to be securely covered.

What is the speed of you if you get sucked into a black hole?

When you are near the event horizon, you would be close to the speed of light - from your own point of view. From the point of view of an outside observer, you would move slower and slower, and never quite reach the event horizon. This has to do with the queer distortion of space and time caused by the black hole.

How far away from earth is the black hole?

There are many black holes in the universe .Scientists believe that there might be a black hole in the centre of our Milky Way galaxy which is about 25,000 light years from earth, and that that is why it rotates about its axis.

Who was the first person to go to a black hole?

No person has ever gone to a black hole. Black holes are extremely dense and have gravitational forces so strong that nothing, not even light, can escape them. It is physically impossible for a human to survive a journey to a black hole.

How does inertia affect black holes?

Inertia causes black holes to keep spinning even after matter falls into them, contributing to their strong gravitational pull. This property is known as frame-dragging, where the rotating black hole drags spacetime around it, influencing the movement of nearby objects and the flow of matter.

How do astronomers search for black holes and what are the challenges of learning about them?

There are two ways of finding black holes. They can look for the effects that their gravity has on nearby objects and they can look for X-rays emitted by matter about to fall into them. A major challenge is that black holes themselves do not emit any light, making them impossible to detect directly.

How did a black hole get created?

A black hole is created when a massive star collapses under its own gravity at the end of its life cycle. This collapse causes the star to become extremely dense, with gravity so strong that not even light can escape its pull, creating what is known as a black hole.

What does the mass of a black hole need to be in order for its mass divided by its volume to be equal to the density of water?

Because radius of a black hole varies directly with mass (twice the mass means twice the radius) per r = 2Gm/(c^2), and the volume varies with the cube of the radius (per v = (4/3)*pi*(r^3) ...) (twice the radius is eight times the volume) there will indeed be a theoretical black hole whose density is equal to water (one gram per cubic centimeter, or one thousand kilos per cubic meter). Since density is mass divided by volume, this becomes an exercise in solving mass for that density.

I calculate a mass of about 3.03 x 10^38 kg, or around a hundred and fifty million times the Solar mass.. which would give the black hole a radius of roughly(!) 450 million km, or about 3 times the distance of the Earth from the Sun. Can somebody else check my calculations please :)

When did Pluto become a black hole?

Pluto has not become a black hole. Pluto is a dwarf planet located in our solar system, while black holes are objects formed from the remnants of massive stars that have collapsed under their own gravity.

Can you control the power of a black hole?

No, it is not currently possible to control or manipulate the power of a black hole. Black holes are extremely massive objects with such strong gravitational forces that even light cannot escape from them, making them one of the most powerful forces in the universe.

What does a black hole do with what it suck in?

A black hole absorbs everything it sucks in, including matter and light. Once something crosses the event horizon of a black hole, it is unable to escape and is thought to be crushed into a point of infinite density at the singularity.

Are black beetles black?

Yes, the beetles answering to the common name of 'black beetles' are in fact black in color.

Where will you go if you got ate by a black hole?

== == * You would go into another dimension, and then cease to exist... either that or you would be in an infinite world of cheese that has borders. Or eventually spat back out as Hawking radiation.

* Most likely you would mushed tomato soup on the floor of your spaceship before you ever really got near the hole. After that you would be part of the spinning debris around the hole and most likely be a smear of atoms until you crashed into the event horizon. You would still be in our universe but the usual rules of physics would be gone and if those atoms made it to the singularity then who knows? You (atomically in pieces) might be spit out of the other end of the hole, you might be rushed out by a white hole, or remain in the center till the black hole overheated and converted what's left to ultrahigh powered radiation in a gigantic black hole explosion. * Mostly, black holes are an intense subject: the gravity curve is so immense that as you approach a black hole, your feet would be pulled in faster than your head, and it would essentially rip you up into the trillions of atoms that make up your body. You wouldn't really go anywhere, at least according to modern science... * If you went through a black hole, even if you did somehow go to another universe or galaxy, you'd suffocate inside it anyway. * Nope, I don't think you will suffocate because you will be ripped into tiny little pieces and ripped up into more tiny pieces, until you become into nothing but atoms.

How do you get black hole badges in khan academy?

telsa= be proficient in 150 exercises

What does the 5 point star mean to black p stone nation picture?

The five-point star is a symbol used by the Black P Stone Nation to represent its five core values: love, truth, peace, freedom, and justice. Each point of the star symbolizes one of these values, encouraging members to strive for them in their actions and interactions with others.

How do you close tonsil holes?

Tonsil holes (crypts) are a normal part of the tonsil anatomy where debris can accumulate. They cannot be permanently closed or sealed without medical intervention like surgery, which is usually only considered if they are causing recurrent infections or other health issues. Practicing good oral hygiene and using salt water gargles can help to keep them clean and reduce bad breath associated with tonsil stones.

How many black holes were in this galixy?

Black holes are a bit hard to detect, so I am pretty sure that not all black holes in this galaxy are known - and I suspect there is not even a decent estimate. But you can expect there to be several.

Which types of technologies has best helped scientists to study very high energy objects in outer space such as exploding supernova black holes and pulsars?
