Time travelling looks like a fantasy but still scientists are trying to make it a reality. Some scientists have claimed that travelling in future is possible but we cannot go back in the past as it will break some basic laws of physics including the renowned problem of paradox. In a similar attempt, researchers have claimed that we can travel in past by using parallel universes.
Scientists believe that there are multiple timelines in parallel universes and we can use them to travel in the past without breaking the laws of physics.
Physicist Howard Wiseman and Dr. Michael Hall, from Griffith University’s Centre for Quantum Dynamics, took the help of researcher Dr. Dirk-Andre Deckert, from the University of California, in developing the theory which looks like science fiction and goes in opposite direction of conventional theories of space and time.
Scientists explained that if there are multiple parallel universe interacting with each other then we can jump into different universe on a different timeline. This means that we can go into parallel Earth located in parallel universe on a different timeline or in the past.
The revolutionary theory has brought a new perspective of universe and space and time correlation. The theory harnesses the power of quantum physics. Professor Wiseman said that the idea of parallel universes in quantum mechanic is not new and has been there since 1957.
“In the well-known ‘Many-Worlds Interpretation’, each universe branches into a bunch of new universes every time a quantum measurement is made. All possibilities are therefore realised – in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonised by the Portuguese,” said Wiseman.
According to the new theory, we live in one gigantic universe and there are many other such worlds which sometimes interact with each other. These replicas might be similar or utterly different on different occasions. All these worlds follow the same time line and interact through a universal force of “repulsion” or bumping into each other.
Hall said this approach can help researchers test the theory of multiverses.Interestingly, he said that if there is just “one” universe, then the theory is reduced to Newtonian mechanics, and if not it reproduces quantum mechanics. This in effect provides a new mental picture of quantum effects.
Although, the new theory might please some people but some researchers are skeptical about it and claim that idea of parallel universes is not possible in reality. If they do exist then why they do not influence our universe at all which suggests that the theory is a fallacy and does not apply on space-time consortium.
