BLACK HOLES - Full Documentary - Penetrating the Mystery of Singularities

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

How Big Are Black Holes?

Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or stuff, in an object.

Another kind of black hole is called stellar. Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.

The largest black holes are called supermassive. These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.


How Do Black Holes Form?
Scientists think the smallest black holes formed when the universe began.

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.

Scientists think supermassive black holes were made at the same time as the galaxy they are in.


If Black Holes Are Black, How Do Scientists Know They Are There?
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting, a black hole.

When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.


Could a Black Hole Destroy Earth?
Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.

Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in. The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now.

The sun will never turn into a black hole. The sun is not a big enough star to make a black hole.


How Is NASA Studying Black Holes?
NASA is using satellites and telescopes that are traveling in space to learn more about black holes. These spacecraft help scientists answer questions about the universe.

How the Universe Works - Black holes - Space Discovery Documentary

The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core's mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole.

Scientists can't directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits x-rays that radiate into space. Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them - emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.

End of the Universe - National Geographic Documentary [HD]

The ultimate fate of the universe is a mind-bogglingly thing to think about. So what’s the final outcome for it all?
One of the furthest reaches of time we dare to predict is the end of the universe. As far as we know this is the end of not only life as we know it but everything that’s ever existed. No more matter, no more light, no more particles, no more nothing. It’s a harrowing reality to fathom, but it’s one we need not worry about too much – if the universe does end, it will be in an unfathomable amount of time as it eclipses trillions upon trillions of years. We must be triumphant on the edge of nothingness as we look forth to the fate of the universe.

The end of Earth, on the other hand, could come at any moment. There’s a number of cosmic events that could wipe this planet right off the universal map. Cataclysmic asteroids, gamma-ray bursts, close supernova blasts, a rogue black hole, and so on. There’s no shortage of astounding yet deadly phenomena in space.

One thing we know for certain is that the Sun’s luminosity increases every billion years by 6%. Our planet will most likely be inhospitable to life in the next billion years. Fast forward 6 billion years and the ground beneath your feet will be completely vaporized. The ultimate fate of the universe is a mind-bogglingly thing to think about. So what’s the final outcome for it all?
The science is anything but conclusive. The Universe might be infinite and never end, it might have never started, but have always been. It could be cyclical in nature with Big Bangs and slow burns occurring on universal eons of scales, or it could splatter out into the truest void.

Our best theories of physics have come up with a few ideas throughout the years and suggest a number of options for the great cosmic deluge. Some hopeful technologists and transhumanists believe we could survive these apocalypses and float off into another universe or dimension. It all depends on what theory you subscribe to. Here are a few.
The big crunch
The Big Crunch could be the ending component to the Big Bang. This model of universal death occurs if the expansion of the universe stutters out and stops expanding. If the average density of the universe isn’t enough to stop expansion, then the universe in a sense will revert and then start to collapse onto itself.

Michio Kaku talks about this when discussing dark matter and his view of the ultimate fate of the universe. The eventual state will be all matter and particles coming together into a black hole singularity. Then boom! This could have been the state that the universe was in when the Big Bang came about. Such an event like this could be evidence of a cyclical repetition of the universe and would confirm many ancient theories of the destiny of the universe. Astrophysicists and other scientists call this conformal cyclic cosmology. Once one universe collapses, it rebirths a new one.
The dichotomy of forces would be like a great celestial wave riding on for trillions of years, just to pull back and crash out again into the infinite over and over again. This is also possible if there is a reversal in dark energy (which some scientists speculate is causing the current expansion effects we see.)

Our current universal experience could be an iteration of an infinite many continuing on through the ages ad infinitum. We’ll explore the philosophical ramifications of this later.
The big freeze
Another popular theory of the end of the universe relies on the laws of thermodynamics and also understanding the true nature of dark energy. The Big Freeze or conversely Heat Death of the universe might come about as the universe continues to expand at an increasingly faster speed.
If the universe continues to expand at an ever-increasing interval, there are a few things that are going to happen those concern physicists. Galaxies and all the stars and planets inside of them will be pulled farther from one another. Deep in the future, intelligent civilizations may look up into the night sky and see nothing as the stars have receded so far away from one another that no light can touch them.

So long alien contact! Eventually, all the stars may be pushed so far from one another that there will be no more explosive reactive energy to make future stars and celestial bodies. And the lights go down in the universe, and they’ll never be live again. Epochs of time crash by with no clock to chart the voyage of the final void.

Soon only the flickers of the infinitesimal particles will remain until their solemn death into nothingness. Colder and colder and the dynamic changes that once paved the way for the fiery life of suns and galaxies will come closer to reaching absolute zero. Once this state is reached, all movement stops.
There is no existence at absolute zero and no energy. At this point, the universe has reached a maximum state of entropy and is no more.

Monster Black Holes - New BBC Documentary 2015 HD

A black hole is a mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it. The theory of
general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[2][3] The boundary of the region from which no escape is possible is called the event
horizon. Although crossing the event horizon has enormous effect on the fate of the object crossing it, it appears to have no locally detectable features. In many ways a black hole acts like
an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black
body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general
relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by
David Finkelstein in 1958. Long considered a mathematical curiosity, it was during the 1960s that theoretical work showed black holes were a generic prediction of general relativity. The discovery
of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.

Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its
surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses (M☉) may form. There is general consensus that supermassive black
holes exist in the centers of most galaxies.

Despite its invisible interior, the presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light. Matter falling
onto a black hole can form an accretion disk heated by friction, forming some of the brightest objects in the universe. If there are other stars orbiting a black hole, their orbit can be used
to determine its mass and location. Such observations can be used to exclude possible alternatives (such as neutron stars). In this way, astronomers have identified numerous stellar black hole
candidates in binary systems, and established that the radio source known as Sgr A*, at the core of our own Milky Way galaxy, contains a supermassive black hole of about 4.3 million M☉.
