i will first start with what are actually black holes.A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. they are perfect examples of blackbody radiators. they absorbs the most of thermal energy and radiates the maximum.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 may form. There is general consensus that supermassive black holes exist in the centers of most galaxies.

most physicists thinks that blackholes may acts like a wormhole through which we can travel in space from one place to another. they are like shortcut in space. according to general theory of relativity an object having mass distort time and space and space time fabric curves around an object having mass.             

more the mass of an object more time and space gets wrapped. sun has very less mass in term of cosmic scale therefore it has very less distortion on space time fabric.

but black holes have so much mass and density that it creates a loop in space time creating a shortcut through which we can travel.

as nothing can escape the immense gravitational field of black holes not even light we have to travel at a faster rate than the cosmic speed limit of light to escape the gravitational field of black hole that is not possible in physics term of view. we can not ever reach the speed of light as far as most scientist thinks. but if we can do this, means we can travel faster than the speed of light we can leave behind most of space and time. this is because most of space time is wrapped around that black hole and it will be easier for us to time travel if we surpass the other end of the black hole.

hello guys am here with my very first post about how according to me universe is expanding and will end one day.

firstly we were told that universe is expanding faster than the speed of light.according to observed data, galaxies seems to move away from us faster than the speed of light. many will think that this would be violating the special theory of relativity given by genius einstein that nothing in space can travel faster than the speed of light in space and time but no its not. this is only true for things itself in space but space time fabric itself is expanding faster than the speed of light. when two galaxies are observed moving away from each other faster than the speed of light it actually indicates that dark energy (responsible for expansion of universe) is expanding between them at a faster rate than the speed limit. galaxies are moving faster than the speed of light in our frame of reference.

now am with my own theory.

according to me universe is not accelerating faster than the speed of light. when universe started expanding for singularity both space time fabric and cosmic matter and anything we see in space started expanding in one direction. they are ineed expanding but havent reached the speed of light yet. they appear to  be moving away faster than the speed of light because we are actually seeing the total acceleration of the cosmic fabric with the accelerating matter. when cosmos itself will exceed the speed of light the time will flow backward same as when an object moves with the speed of light time stops. then universe will again contract and again form a singularity. this will again leads to a big bang and again a new universe will form with new fundamental forces and something new physics that will govern it. at the time when universe will start shrinking all the things will again happen that actually happened in the past till the singularity forms. our existence will again happen in that parallel universe but with different fate. we can say that right now we are not living in a single universe but a part of a duetverse (in which two parallel mirror universe exists). structure of it will be somewhat like a long chain of DNA or chromosome. in that mirror universe dark energy may not be the reason for the expansion of universe but dark matter be the reason for contraction.

i have made this theory on the basis of the data observations of various researchers. this data says that when CMBR(Cosmic Microwave Background Radiation) strucks the thermal part of two colliding galaxies its movement is heading towards one direction. according to this statistical data it might be indicating that universe is heading towards to its destruction.
