Time -Travel Paradoxes

Image
              " Time is just an illusion "            To be able to time travel is an understandably common human fantasy - to anticipate our own futures, to revisit and perhaps change and alter our past lives .Time Travelling is not impossible but it's consequences will play a pivotal role in making everything topsy-turvy. Time is considered to be the fourth dimension . A three dimensional object will have no real existance if it does not last for any time at all.We can thus conclude all mathematical planes are mere abstraction as an instantaneous cube can not exist in the fourth dimension - Time. Relating to time travelling many time travel paradoxes are put forth by  physicist.                    The Grandfather paradox The Grandfather paradox deals with the killing of one's own grandfather before the conception of one...

Time Travelling through a Wormhole !

Image
"Once confined to fantasy and science fiction , time travel is now simply an engineering problem."                                      ~ Michio Kaku Wormholes are theoretically considered to be  'shortcuts' in the universe.  In 1935 , Albert Einstein and Nathan Rossen illustrated the idea of worm holes through the theory of General relativity Creating two different points in the space-time ,and theoretically creating a shortcut that could reduce time and distance taken to travel . Einsteins theory of General relativity predicted the existance of worm holes . However , hitherto no wormholes have been discovered . Wormholes might look exactly like a blackhole . The only difference is there is no Event horizon present in this case.A wormhole can be assumed as a mirrored blackhole, where the fabric of space- time is strecthed. The only dif...

Falling into a BLACK HOLE !

" We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the universe . That makes us something very special. " ~ Stephen Hawking. In his theory of general realativity Einstein predicted how black holes are formed when massive star dies and collapses it leaves a smaller remant core behind. This core's mass is at least 3× bigger than the mass of our sun. A black hole , as it's name suggests is not a hole at all.It consists of huge amount of matter packed into a very small space. When a particle enters a black hole, Space , Time , Laws of Physics are no longer aplicable. A black holes gravity is so strong that even light - the fastest entity in the universe can't escape it. One can't see the black hole . Its invisible. Stephen Hawking believed that black holes can be a passage to another universe.If you were to fall in one you would find yourself in an alternate demension. ...
