Black holes a basic component of the universe
Francisco J Vergara Ortiz
When you think about black holes, many things come to your mind, some are the product of movies and television created by Hollywood, others are myths that people say almost every time, that a black hole conversation came up to the table. It is say to be cosmic vacuum cleaners and some people says that they are portals to others universe, or other dimension. Well that’s just myth, assumptions, and theories because no one has ever been in a black hole. But what a black hole really is? How many types of black holes we know and what is the Schwarzschild radius? And if they’re the dark black in a black sky (universe) how we know they exist?
In theory a black hole is so dense that even light can’t escape from it, this happens because of gravity as we learned in general physics every object exert a gravity force into another object, when an object is so dense everything near it radius of gravity will collapse into it by the law of gravity, and that is what a black hole is, a body of mass so dense that even light that is called photon which are mass less can’t escape from it. Also in principle every object can be made into a black hole by reducing that object to cero volume, but conserving its mass and gravitational force, when this happens the object undergoes into gravitational collapse, it attract itself, compressing his mass into a singular point. This black hole will have a gravitational self attraction called the Schwarzschild radius. But the only object that can become a black hole by itself are stars with 10 to 15 times the mass of our sun when they explode (die) they collapse onto itself and forms a stellar black hole, a really little one with only a few tens kilometers of Schwarzschild radius but with three to ten times the mass of our sun.
As we know there are two types of black holes the stellar one that is when a supernova dies and the super massive black holes (SMBHs) this last ones are still a mystery, no one knows how they form, but it’s believed to be the center of almost every galaxy including our milkyway galaxy. (SMBHs), weights up millions or billions times the mass of our sun. But they are really cosmic vacuum cleaners? The answer is no, to be sucked into a black hole you must cross the Schwarzschild radius this radius can be calculated by this equation R=2GM/c^2 where c is the speed of light, M the mass, and G the gravitational constant. If for example a black hole has the mass of our sun, his Schwarzschild radius will be only 3 kilometers, and in order to get sucked in you must be at least 3kilometers from its center. But there are black hole out there with billions times the mass of our sun. At this time the biggest one our scientist have seen is about 18 billion the mass of our sun called (Oj 287), I use this formula to calculate his radius and the result was amazing about 53 billion kilometers, to get and imagination of how big it is if every star where a kilometer it would be 0.18 the number of stars on our galaxy, and to get a direct comparison this radius is about 8 millions the time of our planet radius.
Another fact that I found interesting is the force it exerts on another objects lest take the same black hole and apply the law of universal gravitation by Newton. If our planet where on the border of the Schwarzschild radius of this monster the force that it will exerts will 5.06845 x 10^27 Newton onto our planet, that’s a lot of force maybe one of the most powerful things in the universe are the black holes, if they are not. They are so powerful that they are what bounds a galaxy and makes them move around it, because they function like stars, like our sun domains our planet system a black hole domains the galaxy.
How do we know they exist, first of all it is impossible to see this stars with the visible spectrum because light cannot escape from it, but for example is there is a normal star near a black hole the black hole will pull matter towards him, in this process of taking matter out of the nearby star or stars, the black hole gains kinetic energy, this energy is so big that the atoms gain millions of Kelvin and when this happens the black hole emits x-ray in the form of jet out to the space. This jets heat up the surrounding and prevents gas to collapse into the center, and that is what we see and know they exist.
We know what are they, how them work, and a lot of things that still are a mystery. But black holes are basic things in the universe, as we learned they are not cosmic vacuum cleaner sucking everything in their way. First and object must cross his Schwarzschild radius, and the x-rays they produce prevent gas from falling inside it. Allowing nearby galaxies to form and growth, after all there is an injured and beneficial part of this, and our sun, our planet, and ourselves seems to be the beneficiary of this far a well monsters.

Radhasoami Faith View of Modus Operandi of Creation of Universe
ReplyDeletePart - I
There is cosmological evidence for God and the Universe existed before Big Bang please.
Stephen Hawking writes in The Grand Design, “It is not necessary to invoke God to light the blue touch paper and set the Universe going.” Hawking said the Big Bang was merely the consequence of the law of gravity. In A Brief History of Time, Hawking had suggested that the idea of God or a divine being was not necessarily incompatible with a scientific understanding of the Universe.
Although Hawking is very close to Truth yet he is not perfect in his views while discarding the role of divine being. I consider the role of eternal gravity uppermost but I strongly differ with Hawking on the role of divine being. I consider Divine Ordainment is the cause of Creation of Universe.
Now I give Radhasoami Faith view of Creation Theory. In Sar Bachan (Poetry) composed by His Holiness Soamiji Maharaj the August Founder of Radhasoami Faith the details of creation and dissolution has been described very scientifically. It is written in Jeth Mahina (name of Hindi moth) in this Holy Book: Only He Himself (Supreme Father)and none else was there. There issued forth a great current of spirituality, love and grace (In scientific terminology we may call this current as gravitational wave). This is called His Mauj (Divine Ordainment). This was the first manifestation of Supreme Being. This Divine Ordainment brought into being three regions, viz., Agam, Alakh, and Satnam of eternal bliss. Then a current emerged with a powerful sound (this was the first Big Bang). It brought forth the creation of seven Surats or currents of various shades and colours (in scientific terminology we may call it electromagnetic waves). Here the true Jaman or coagulant was given (in scientific terminology this coagulant may be called as weak nuclear force and strong nuclear force). Surats, among themselves, brought the creation into being.
These currents descended down further and brought the whole universe/multi verse into being i.e. black holes, galaxies etc. were born.
I would like to add further that sound energy and gravitational force current are non polar entity and electromagnetic force is bi-polar. Hence spiritual polarization, if occurred, is occurred in the region of Sat Lok and region below to it only.
Infinite expanse of gravitational force field is the region of dark energy.
In Bible it is written that in the beginning was the Word; the Word was with God; and the Word was God.
According to Radhasoami Faith “Shabd (Word) is the beginning and end of all. The three loks (worlds) and the fourth Lok, all have been created by Shabd.” (Sar Bachan Poetry)

Here the true Jaman (coagulant) was given. The spirituality coagulated as it were, and Surats (spirit entities), among themselves, brought the creation into being. Thereafter, another Jaman (coagulant) was given. Regions from Agam Lok (Inaccessible Region) to Sat Lok (True Region) were created during the first creational process. That creation is true. That region is eternal. There is no trace of evil and suffering. This was the creation for many Yugas and ages. Then there appeared a dark coloured current
That current appeared like a dark coloured stone set in a white one and was absorbed in the Darshan of True Being. Then there appeared two Kalas i.e. currents (viz. Niranjan and Jyoti) and they together evolved the creation of five Tattwas (elements) four Khans (species, categories of life) and three Gunas (qualities). The three Gunas (qualities) brought about the expansion and proliferation . They created Rishis and Munis (sages and holy men), gods and godly human beings and demons. Egotism then increased much. Niranjan separated himself from the rest, putting the burden of looking after the creation on them. Nobody could know of Niranjan. Even the Vedas referred to Him as Neti Neti (Not this, Not this). They did not get Darshan (Vision) of Niranjan. They made conjectures. Then how can anybody have knowledge of Sat Purush (True Being), Source of Niranjan and all that exists.
Scientifically here Jyoti represent three Fundamental Forces of Quantum Mechanics i.e. electromagnetic force, weak nuclear force and strong nuclear force. NIRANJAN is the fourth Fundamental Force i.e. Gravitation Force. Scientific explanation follows in support of my views.
Part-III
Einstein struggled and failed to formulate this theory, but it has already been shown that at high enough energies electromagnetism and the weak force are the same force known as the electroweak force. It is theorized that if energies are increased even further and neutrinos acquire mass, which has now been fully documented, all the known forces will reduce to the same force thus providing the basis for the Grand Unified Theory. This high energy level existed only during the very early expansion of the Universe known as the Planck Epoch which existed up to 10 to the negative 43rd seconds after the Big Bang where the four fundamental forces – electromagnetism, weak nuclear force, strong nuclear force and gravitation – all had the same strength. After that point the energy level decreased and gravity separated from the other 3 fundamental forces and with condensation of elementary particles (quarks, leptons, and gauge bosons) into matter formed the so-called Standard Model of today’s Universe.
