Time travel is a concept that humans are drawn to, largely because of the perceived impossibilities within it. Two dimensional times travel is that which changes the past, taking a possible world and bringing it into existence, creating branching timelines. They are very distinct in nature, in that one dimensional time lap does not involves disrupting the history as the time traveller knows it, whereas two dimensional time travel ‘creates’ a new alternate reality time stream which can range anywhere from being almost identical to bearing little resemblance to the time traveller’s remembered reality. I my opinion one dimensional time travelling is logically possible, because of the fact that there are no contradictions in our explanations of time travel, and because we can conceive of a coherent world where some of the people we interact with are time travellers from the future, and where we might in future go back to the past and interact there.

Conceptual impossibilities within time travel range from those concerning personal identities to causal loops to the Grandfather Paradox, and I’ll present them as such.
According to Albert Einstein, time is relative. This means that two different, moving observers can perceive the length of a period of time between the same events differently. With time theory, the conceptual models of the special and the general theory of relativity can be distinguished from one another.
The aforementioned time-perception model is assigned to the special theory of relativity. The general theory of relativity deals with accelerated systems and defines gravitation as a curvature of space and time. The curvature results from the existence of masses. Kurt Gödel invented the world formula for time travel on the basis of Einstein's theory of relativity. Stephen Hawking fluctuates between the feasibility of time travel and the negation thereof. Roy Kerr tried to prove the existence of black holes, while Kip Thorne reflects how a wormhole must be designed in order to travel through time. Physicists, Amos Ori and Ronald L. Mallet, introduce current visions of a time machine. A question arises from the basis of time travel philosophy, including, as a result of the research with the LHC at CERN on Switzerland, to what extent is time travel feasible and what factors related to neurological and human consciousness are relevant in the context of the problematic of causality. As a result, it is worthwhile to consider how time travel research could allow an eternal life. Time travel has been known as science fiction but now scientist has been believing time travel is possible based on the physics laws.
Scientists have hope that modern technology will help them discover wormholes and explore them. A black hole has been discovered by Einstein's theory of general relativity, which showed that when a star dies, it leaves behind a small, dense remnant core. If the core’s mass is more than the sun, the force of gravity overwhelms all other forces in which it transforms into a black hole. Scientists have said that black holes can destroy anything that goes in it and it could be hard to get out of a black hole, once something went in it. In an interview by physicist Loir Burke, he states, “One possibility is that black holes may allow us to travel to very remote places in the universe, or another universe entirely,” (Kenney, “Black Holes and Space Time”). Black holes may have evidence that there are different kinds of parallel universe. Scientist are trying to create a black hole, here on earth, to see what blacks can do as in sending information to another universe.
