Astrophysics

Black holes are formed when massive stars collapse under their own gravity at the end of their life cycle. As the core of the star collapses, it creates a dense region with gravity so strong that not even light can escape, known as a black hole.

Yes, black holes have a diameter, which is referred to as the event horizon. The event horizon is the region beyond which nothing, not even light, can escape the immense gravitational pull of the black hole. This diameter can vary depending on the mass of the black hole.

Black holes are created when a star of enormous mass goes through the supernova stage. The supernova has left an extremely dense core that soon collapses under its own gravitational pull. The gravity is so strong that nothing (yes, nothing, not even light) can escape from it. A black hole creates a huge disturbance in space and time which leads some scientists to believe when 2 blach holes join, a wormhole (in the link below) is made.

Some main methods in astrophysics include observation using telescopes, simulations with computational models, and theoretical calculations based on known physical principles. Theories in astrophysics include the Big Bang theory for the origin of the universe, general relativity for understanding gravitational interactions, and the theory of stellar evolution to explain the life cycles of stars.

They really can't guess, since it was obviously millions of trillions of years since the Big Bang, which formed the Earth and began the Universe expanding. But not everyone believes in the big bang religious beliefs say that God created the Earth and the Universe.

Yes. Black holes suck things inside. The only way to suck these things inside is by massive form of gravity. Black holes can suck in as little as a small chunk of rock, or as big as a planet.

Black holes don't "use" gravity, they are a side effect of it. To create a black hole requires a force that can grow infinitely: of the strong nuclear, weak nuclear, electromagnetic and gravity forces, only gravity is infinite in it's strength that is it is based on the masses and distances of the objects involved, it has no limit. A black hole is generated when enough mass joins together and the force of gravity generated is so strong that light can't escape it (at event horizon and lower.) In most cases for the mass to get that heavy, gravity has to bring them together in the first place (every so often high speed collisions will join masses, but it rare.) It's almost a snake biting it's tail: gravity pulls the parts together, the parts coming together increases gravity, that gravity pulls more parts .......

Unless specifically stated by a sign, the speed limits for cars are:

Motorway: 70 MPH

Dual Carriageway: 70 MPH

Single Carriageway: 60 MPH

Built up areas: 30 MPH (in towns, villages etc)

Other vehicle types such as trucks and buses have their own speed limits.

Approx $18 a session and they make you buy in bulk.

No its not 18 its $12 and you do not buy it in a bulk you can buy a package for 3 months min in the lowest which is 54. and that's $99. Or single packages for 12 a peice.

Depends where, maybe some will be $20 or a really good one could go up to $100

YES!!! it crushes everything into a singularity. you would be spread out into data. it would appear like nothing is happening and time would slow down. then you would be sucked up into the black hole becoming jumbled up with all the other matter that has been crushed, and theoretically teleported into a dimension without black holes(please note i think that theory is just BS) where you would theoretically be able to take back the information in the black hole. So yes you would die but THEORETICALLY you would be able to be reasembled (kind of)

Firstly if you reading this as a ignorant rasist or childish adult that needs to grow up then read but keep you comments to your self...

Hi firstly one cannot generalize as such but, as research has proven that different cultures of men do have size difference in a majority of the culture, i will paste the proof at the bottom..

I also want to add that just as the African and Indian Elephants differ in many ways such as size and color and bone structure even if they are from the same dna family, one can understand how they adapted as such because of invoroment and climate and food...just as such we humans in diffrent regions adapted and changed...

Now as for your question i think its obvious to look ad human evolution according to culture,sexual rituals, ways of living and habitat....

i live in south Africa and i know the African culture very well..

The missionary position was used in Europe, and you can go do research the proof is all on the net....In Africa it was proven that almost all tribes use to have intercourse with the man from behind and normally on knees or standing.therefor the distance is greater to enter the vagina of the female, so just like all nature animals and humans adapt and their bodies adapt to habitat, ways of life and so on black mens penises adapted too....( it is not said all black men have larger penises as it is not as thought, but genetically in general the black male did evolve abit more.

Same for Asians, their are studies that hundreds of years back until now the preferred position is with the woman on top.Therefor less penetration is needed or the woman could feel un comfortable... and surpressing ontop of penis did not encourage growth as such of black culture.

As for the larger bottoms of female black African woman...i believe their are 3 factors that could be considered...firstly hormonal chemical in-balance as African woman are more stressed in their culture and carry most responsibility..and the second is that majority of African woman from many tribes and countries tighten their babies around the waist on their back resting against their bottom all day while still small.they slide down and irritating the woman so they keep tightening the blankets holding the baby.and over the decades its possible that the evolution of doing the same thing and mind over matter caused the butt muscles to grow as support for that....THIRDLY and most likely it is also proved that the black culture in general have larger muscles than the whites, longer legs and so on...After all the but muscle is the largest single muscle in the human body.

I hope that might answer your question...and if it was as a sarcastic childish ignorant racist meaningful question, well grow up then, as you placed the question under monkeys and genetics...rather put it under human genetics and human evolution.

Dr. Eduardo Gomez de Diego, CEO of Andromedical, a men's medical company, decided it was time to confirm or deny the myths about the penis size around the world after treating more than 2,000 patients interested in enlarging the size of their penis. Dr. Gomez de Diego, the European Expert on such delicate issue, compiled scientific data from 15 countries.

The study results showed that the average world size penis when erect is 14 centimetres (5.5 inches). The biggest averages were registered in France 16 cm (6.2 in), Italy 15 cm (5.9 in), Mexico 14.9 cm (5.8 in) and Spain 14 cm (5.5 in). In the United States, the average is 12.9 cm (5 in) while in Venezuela is 12,7 cm (4.9 in), and in Brazil is 12.4 cm (4.8 in). The smallest averages were found in India 10.2 cm (3.9 in) and South Korea 9,6 cm (3.7 in) and in Africa 17 cm (6.6)

But their are family blood lines and certain genetic factors that give abnormal size. but above was found in general size when all calculated and divide to percentage.

Yes, especially in a climate-controlled (read: air conditioned) environment with low humidity. Plumbing fixtures which do not get used lose their trap seal from evaporation, and sewer gas can then enter the house.

A group of planets moving around a star is called a solar system. Planets outside our solar system are called exoplanets. Despite the difficulty of detection, many hundreds have been discovered recently, orbiting other stars.

Black holes are the end result of a supernova. Eventually the gravity of the dying star causes it to collapse into itself, resulting in a black hole.
Get enough mass close together and it will shrink into a black hole (about 10 solar masses will probably do nicely but 10000 solar masses will undoubtedly make a black hole if it is concentrated in a small enough volume).
Black holes are created when a giant star collapses in on its own core to be consumed in its gravity, caused by the growing level of density.

Stephen Hawking studied theoretical physics, particularly in the fields of cosmology and quantum gravity. He made significant contributions to our understanding of black holes and the origins of the universe. His work focused on unifying the theories of general relativity and quantum mechanics.

No, mercury is a chemical element found on the periodic table and does not contain oxygen in its pure form.

No one knows. Most black holes are assumed to not have or be part of a wormhole (hole in space from one side of the universe to another) - most will just crush anything to infinitely small parts.

Your question is incomplete. You asked a question that is like, "Where is the hole in the Swiss cheese?". There are usually several holes and each hole has a specific item or loom of items running through it. For example, the speedometer cable may have a hole in the firewall for itself or the A/C lines have holes in the firewall for their passage. BETTER QUESTION: WHERE IS THE HOLE IN THE FIREWALL FOR THE _________________?

Electromagnetic radiation, in layman terms, light. Atoms of gas and dust and other matter are spinning around the black hole at such incredible speeds that the heat from the friction of this rubbing action causes the immediate area just outside the event horizon to intensely light up and glow, thus creating a Quasar.

It would seem that all things organic would be shorter, stouter. Takes more energy to move around, and things fall faster, and the impact hurts more. It depends how heavy the gravity would be, Earth's is considered standard gravity, which means items fall and accelerate a set rate, on a heavy gravity planet, these numbers would be faster. I do not think that humans could live on a heavy gravity planet, unless it were just slightly higher than Earth's. Little things, like swallowing, moving our hands to scractch our necks, would be hard on this type of planet. Plants and other animals would likewise be affected.

^^^^Are you dumb? Organisms would adjust to the gravity forces and it would eventually feel normal to us. Humans would be alot stronger and faster, heavier objects would sink in the ground. That's about it.

According to Newton's laws, the conditions in which a body accelerates are only those in which a force is acting upon it. With no force acting upon it, a body would not accelerate. With a force acting upon it, it would accelerate by an amount proportional to the force and inversely proportional to its mass.

A black hole is most often made made when a large enough star supernovas and then collapses in on itself. Our sun will probably not become a black hole when it dies, it's too small. A star (neutron-degenerate) that creates a black hole has to be at least 3x more massive than our sun. Most likely when our sun dies it will just create a white dwarf then a brown or black dwarf (mass but no light is given off.)

Yes, the hole of a flesh tunnel may close over time if left empty. The extent of closure can vary depending on the length of time the tunnel has been empty and individual factors like skin elasticity. In some cases, the hole may completely close while in others it may leave a small scar or dimple.
