hello guys am here for 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.
