In search of black holes astrophysicists are relying on indirect observations. Only the measurement of the event horizon of a black hole directly would be a direct evidence. However nobody done it yet, so for now an existence of BH is a hypothesis

“This discovery also presents a puzzle for astrophysicists,” said Hawking. “The mass of each of the black holes are larger than expected for those formed by the gravitational collapse of a star — so how did both of these black holes become so massive?”
This question touches on one of the biggest mysteries surrounding black hole evolution. Currently, astronomers are having a hard time understanding how black holes grow to be so massive. On the one end of the scale, there are “stellar mass” black holes that form immediately after a massive star goes supernova and we also have an abundance of evidence for the existence of the supermassive behemoths that live in the centers of most galaxies. There is a disconnect, however.
If black holes grow by merging and consuming stellar matter, there should be evidence of black holes of all sizes. But “intermediate mass” black holes and black holes of a few dozen solar masses are astonishingly rare, throwing some black hole evolution theories into doubt.(http://news.discovery.com/space/hawking-gravitational-waves-could-revolutionize-astronomy-160216.htm )
Albert Einstein’s Thought Experiment and Equivalence Principle is Misleading
Lincoln Barnett, Universe and Dr.Eintein, London 1949, page 69.
"This physicists are still in the elevator, but this time they really are in the empty space, far away from the attractive power of any celestial body.A cable is attached to the roof of the elevator; some supernatural force begins reeling in the cable; and the elevator travels "upward" with constant acceleration, i.e. progressively faster and faster. Again the men in the car have no idea where they are, and again they perform experiments to evaluate their situation. This time they notice that their feet press solidly against the floor come up beneath them.
If they release objects from their hands, the objects appear to "fall".If they toss object in a horizontal direction they do not move uniformly in a straight line, but describe a parabolic curve with respect to the floor.
And so the scientist, who have no idea that their windowless car actually is climbing through interstellar space, conclude that they are situated in quite ordinary circumstances in a stationary room rigidly attached to the earth and affected in normal measure by the force of gravity. There is no way for them to tell whether they are at rest in a gravitational field or ascending with constant acceleration through outer space where there is no gravity at all.
Lincoln Barnett, Universe and Dr.Eintein, London 1949, page 70.
So Einstein's Law of Gravitation contain nothing about force. It describes the behavior of objects in a gravitational field - the planets, for example - not in terms "attraction" but simply in the terms of the paths they follow. To Einstein, gravitation is simply part of inertia; the movements of stars and the planets arise from their inherent inertia; and the courses they follow are determined by the metric properties of space -- or, more properly speaking, the metric properties of the space-time continum.
(Universe and Dr.Eintein, Lincoln Barnett, London 1949, page 69 - 72).
Einstein’s thought experiment mentioned above describe three events that become the objects of observation in the elevator :
1. They notice that their feet press solidly against the floor come up beneath them.
2. If they release objects from their hands, the objects appear to "fall".
3.. If they toss object in a horizontal direction they do not move uniformly in a straight line, but describe a parabolic curve with respect to the floor.
From these three events in the elevator , an observer outside the elevators conlude that gravity is nothing about force. Furthermore describes the behavior of objects in a gravitational field - the planets, for example - not in terms "attraction" but simply in the terms of the paths they follow.
The thought experiment mentioned above is incorrect. Three objects of observations do not fully describe the theory of gravity, namely can not describe at least two other events that caused by the force of gravity:
1. The celestial bodies in orbit, for example, the orbiting of the planets around the Sun.
2. The occurrence of tide-low tide caused by the attraction of the moon.
Of course it will be very difficult to illustrate two things mentioned above in the elevator. What could be described in the elevator is only related to objects that have weight and mass. Therefore, the thought experiments mentioned above is incomprehensive, illogical, and can be misleading.
Actually, thought experiments can be made to obtain the result they wanted to get. Albert Einstein made a mistake in his thought experiments.
Why the Equivalence Principle is False?
The Equivalence Principle proposed by Albert Einstein that underlying of his theory of relativity, was concluded by the method of inductive reasoning from his thought experiment, but special events as a reference is incomplete that caused by not in single ekxperiment (incomprehensive). Therefore the equivalence pinciple is false.and misleading.
Isaac Newton's theory of gravitation first enabled an explanation of why there were generally two tides a day, not one, and offered hope for detailed understanding. How about Enstein's general relativity on tide-low tide??.
Contradiction Between the Special and General Theory of Relativity
The most contradiction between Special and General Relativity Theory is about the existing aether. In special relativity Einstein didn’i believe that aether dexist, and in this case he agrees with Michelson-Morley experiments. But in general relativity says that aether exist. Ironiccaly, many of physicist who believe in general relativity ignored the existing of aether.
Einstein sometimes used the word aether for the gravitational field within general relativity, but this terminology never gained widespread support.
The standard model does not include an explanation of gravity, which most scientists believe is best described by general relativity theory. This theory claims that gravity is not a force that propagates across space but results from masses distorting the ‘fabric of spacetime’ in their vicinity in some mysterious way. Since ‘curved spacetime’ is a geometrical abstraction, relativity theory is merely a mathematical model and does not provide a realistic understanding of gravity. (David Pratt, The Farce of Modern Physics, Januari 2008)
Tesla published a prepared statement on his 81st birthday (July 10, 1937) critiquing Albert Einstein's theory of relativity. The following is a portion of that statement:
"... Supposing that the bodies act upon the surrounding space causing curving of the same, it appears to my simple mind that the curved spaces must react on the bodies, and producing the opposite effects, straightening out the curves. Since action and reaction are coexistent, it follows that the supposed curvature of space is entirely impossible - But even if it existed it would not explain the motions of the bodies as observed. Only the existence of a field of force can account for the motions of the bodies as observed, and its assumption dispenses with space curvature. All literature on this subject is futile and destined to oblivion. So are all attempts to explain the workings of the universe without recognizing the existence of the ether and the indispensable function it plays in the phenomena." (peswiki.com)
Sebabnya: karena teori gravitasi Tesla mempersyaratkan adanya aether, walaupun keberadaan aether tidak bisa dibuktikan/tidak terdeteksi oleh peralatan deteksi manusia modern.Keberadaan aether yang tidak terdeteksi pertama kali disampaikan oleh Aristoteles pada abad sebelum masehi, kemudian dipopulerkan oleh filsuf Perancis Rene Descartes, ke dua pemikir besar itu percaya adanya Tuhan. Ke duanya adalah orang beriman kuat.
Dengan mengakui adanya aether yang tidak terdeteksi berarti mengakui adanya Tuhan Yang Maha Kuasa.
Teori gravitasi Albert Einstein -Relativitas Umum - juga mempersyaratkan adanya aether. Apakah Einstein juga mengakui adanya Tuhan Yang Maha Esa ?
Persisnya tidak. Tetapi Einstein bukan seorang atheis. Einstein tidak percaya adanya Tuhan yang bisa memberi ganjaran dan hukuman, istilah populernya tidak percaya Personal God. Tetapi Einstein percaya adanya Tuhan versi Tuhannya filsuf Spinoza, Spinoza adalah filsuf Yahudi yang diusir oleh kaumnya keluar dari tanah kelahirannya, kemudian menetap di Eropa. Kepercayaan Spinoza di kemudian dari dikenal dengan sebutan Deisme. Kepercayaan Einstein adalah Deisme, yaitu percaya adanya Kecerdasan Yang Tertinggi atau Super Intelligence.
Bedanya dengan agama:
1. Agama berdasarkan kitab suci dan memiliki cara-cara peribadatan (syariat) sesuai yang ditentukan dalam kitab suci itu.
2.Kepercayaan, misalnya Deisme, kepercayaan berdasarkan akal pikiran semata dan tidak memiliki cara-cara peribadatan.
Kembali menjawab pertanyaan mengapa teori Einstein yang dipopulerkan?
Sebab dalam teorinya sebelumnya - teori relativitas khusus (1905) - Einstein mengumumkan agar mengabaikan/lupakan adanya aether. Dalam teorinya berikutnya - teori relativitas umum (1915) - pada awalnya juga mengabaikan adanya aether. Namun setelah tahun 1919 Einstein menyadari bahwa tidak mungkin adanya warped space tanpa adanya aether. Sehingga baru pada tahun 1920 Albert Einstein mengakui bahwa aether itu 'harus' ada. General Relativity impossible without aether.
Namun ,,,,pengakuan Einstein pada tahun 1920 itu 'dianggap angin lalu' .......Mereka mengakui teori relativitas umum tapi tidak mengakui adanya aether, dan mereka berusaha menciptakan teori-teori baru untuk mengganti teori tentang aether, antara lain teori Dark Matter dan Dark Energy.
Berhasilkah mereka?? Sayang sekali tidak berhasil, dan dua teori itu sejak tahun 2000-an dianggap sebagai bagian dari The 9 Biggest Unsolved Mysteries in Physics,,,.....dan mulai ada yang mengatakan dua teori itu do not make sense.
"For sure, there are regions of space with far less matter — stars, gas, dust, and even dark matter — than average. In fact, there are other voids that are of comparable magnitude that have been discovered since. One could cause this effect by a large region that was completely empty of galaxies, which is the “hole in the Universe” option that many reporters (and, ahem, press releases) flock to. But it could also be caused by something far less spectacular: a minor underdensity over a larger volume/longer slice of the Universe. Until we do a dedicated, 3D cosmic map (using spectroscopy to verify the redshift of the observed galaxies) over the region of interest, we won’t know for certain how these galaxies are distributed. But as far as what you’ve heard, there may not be an interesting void there at all, much less a region with no matter of any type." (Is This Actually A Hole In The Universe?-ForbesCom)
Why all the galaxies and stars near the hole do not follow the curved path of the hole? A hole in the universe as proof that in reality there is no such thing as warped space. A very big hole in the universe truly a confirmation by the universe itself / self-proving that the general relativity theory and big bang theory was wrong.

gravity as the effect of curves in “space-time”
In 1955, Nathan Rosen tried to argue that gravitational waves don’t carry any energy, so they’re just a formal mathematical construct with no real physical meaning.
Science isn't consensus, if it's concensus, it isn't science.
Why all the galaxies and stars near the hole do not follow the curved path of the hole? A hole in the universe as proof that in reality there is no such thing as warped space. A very big hole in the universe truly a confirmation by the universe itself / self-proving that the general relativity theory and big bang theory was wrong.
There’s basically a hole in the universe -- a region where there’s much less matter than there should be. And we don’t know why it’s there.

gravity as the effect of curves in “space-time”
In 1955, Nathan Rosen tried to argue that gravitational waves don’t carry any energy, so they’re just a formal mathematical construct with no real physical meaning.
Science isn't consensus, if it's concensus, it isn't science.
If gravitational waves are not affected by gravity lensing, then under some lines of sight the associated gamma ray bursts would arrive with different delays potentially smoothing the signal, or producing multiple signals if the paths are significantly different in length.
Have short gravity lensed gamma ray bursts been detected in the past, via signal smoothing or multiple signals?
Also what does the 0.4 second delay of the gamma ray burst provide in the way of information about the location/distance of the event?
Based on this thought experiment, Einstein concluded that gravity is not a force of attraction, for no such force is required. Instead, it is something quite different — a curvature in the fabric of space-time.( http://www.thestar.com/news/insight/2012/08/18/einstein_discovered_that_gravity_is_not_a_force_but_a_curvature)
In general relativity, clocks at a position with lower gravitational potential – such as in closer proximity to a planet – are found to be running more slowly.
So my point is that it isn't meaningful to ask how a gravitational force affects time, because there isn't any such thing as a gravitational force. What does affect time, or more precisely spacetime, is the presence of matter, and that produces the appearance of a gravitation force. Your question should really be "How can (the curvature of) time affect gravity?" i.e. exactly the reverse of what you asked!
Gravity is currently understood to be curvature of spacetime, so mathematically it's unambiguous why gravity should affect time. But to leave it at that would be cheating, no? So I'll try to give an explanation of why you'd intuitively expect gravity to affect time. This is called the Einstein Tower thought experiment. If you've seen the phenomenon of time dilation in special relativity before, you'll notice that the way time behaves depends a lot on how light behaves. It's not crucial you know this but the spirit of the following explanation is the same.
Let's assume for a moment that gravity doesn't affect light in any way. Suppose you create a photon with energy $E$ on the ground and fire it up to the top of a tower where this photon is converted into an equivalent mass $m=E/c^2$. This mass will fall back to the ground and once it reaches the ground it will have gained extra energy $mgh$ because it fell through the gravitational field. If you started with energy $E$, you end up with energy $$E'=E+mgh=E(1+gh/c^2)$$ So every time you do this, you create energy! Surely something is wrong -- it must've been our assumption that gravity doesn't affect light. The most obvious fix then is to assume that the photon lost energy as it climbed up the gravitational field and that its energy at the top is $$E_{top}=E(1+gh/c^2)^{-1}$$ This is (a first approximation to) the phenomenon of gravitational red shift where photons lose energy as they climb out of a gravitational field.
Now, if you remember that the photon frequency is related to its energy by $E=h\nu$, you'll see that the frequency (~$1/T$ which is the "internal clock" of a photon) obeys the same relation as above. This is indicative of gravity affecting time -- in fact it's immediately obvious that any clock based on the frequency of light will run at a slower rate higher up in the gravitational field.( )
Gravitational time dilation has been experimentally measured using atomic clocks on airplanes. The clocks aboard the airplanes were slightly faster than clocks on the ground. The effect is significant enough that the Global Positioning System's artificial satellites need to have their clocks corrected.
Additionally, time dilations due to height differences of less than 1 meter have been experimentally verified in the laboratory.
Gravitational time dilation has also been confirmed by the Pound–Rebka experiment, observations of the spectra of the white dwarf Sirius B, and experiments with time signals sent to and from Viking 1 Mars lander.(wikipedia)
“Different parts of the universe are moving at different rates,” deGrasse Tyson said, “and time has some relative aspects to it. For example, the GPS satellites, the clocks on them tick at a different rate than clocks on Earth’s surface because when you move far away from the source of gravity, your time speeds up.” (http://www.rawstory.com/2013/09/neil-degrasse-tyson-explains-how-gravity-affects-the-flow-of-time/ )
Clocks in a gravitational force.
When comparing a clock under the influence of gravitational forces with one very far from such influences it is found that the first clock is slow compared to the second. To see this consider the same clock we used in the Special Theory of Relativity. For this experiment, however, imagine that the clock is being accelerated upward, being pulled by a crane. The clock gives off a short light pulse which moves towards the mirror at the top of the box, at the same time the mirror recedes from the pulse with even increasing speed (since the box accelerates). Still the pulse eventually gets to the mirror where it is reflected, now it travels downward where the floor of the box is moving up also with ever increasing velocity.
On the trip up the distance covered by light is larger than the height of the box at rest, on the trip down the distance is smaller. A calculation shows that the whole distance covered in the trip by the pulse is larger than twice the height of the box, which is the distance covered by a light pulse when the clock is at rest.
Since light always travels at the same speed, it follows that the time it takes for the pulse to go the round trip is longer when accelerating than when at rest: clocks slow down whenever gravitational forces are present.
This has an amazing consequence: imagine a laser on the surface of a very massive and compact planet (so that the gravitational field is very strong). An experimenter on the planet times the interval between two crests of the laser light waves and gets, say, a millionth of a second. His clock , however, is slow with respect to the clock of an observer far away in deep space, this observer will find that the time between two crests is larger. This implies that the frequency of the laser is larger on the planet than in deep space: light leaving a region where gravity is strong reddens. This is called the gravitational red-shift

The Speed of Light and the Index of Refraction
"Nothing can travel faster than the speed of light."
"Light always travels at the same speed."
Have you heard these statements before? They are often quoted as results of Einstein's theory of relativity. Unfortunately, these statements are somewhat misleading. Let's add a few words to them to clarify. "Nothing can travel faster than the speed of light in a vacuum." "Light in a vacuum always travels at the same speed." Those additional three words in a vacuum are very important. A vacuum is a region with no matter in it. So a vacuum would not contain any dust particles (unlike a vacuum cleaner, which is generally full of dust particles). (http://www.rpi.edu/dept/phys/Dept2/APPhys1/optics/optics/node4.html )
Remember, it is not curved space, but the human mind which cannot comprehend infinity and eternity! ( http://www.freedomtek.org/en/texts/nikola_tesla_interview_1899.php)
In science fiction, space and time warps are a commonplace. They are used for rapid journeys around the galaxy, or for travel through time. But today's science fiction, is often tomorrow's science fact. So what are the chances for space and time warps. (http://www.hawking.org.uk/space-and-time-warps.html ).
Another piece of evidence is known as the time-delay experiment. The mass of the Sun warps space near it, therefore light passing near the Sun is doesn’t travel in a perfectly straight line. Instead it travels along a slightly curved path that is a bit longer. This means light from a planet on the other side of the solar system from Earth reaches us a tiny bit later than we would otherwise expect. The first measurement of this time delay was in the late 1960s by Irwin Shapiro. Radio signals were bounced off Venus from Earth when the two planets were almost on opposite sides of the sun. The measured delay of the signals’ round trip was about 200 microseconds, just as predicted by general relativity. This effect is now known as the Shapiro time delay, and it means the average speed of light (as determined by the travel time) is slightly slower than the (always constant) instantaneous speed of light.
