Time travel is something every major scientist around the world is working upon for very long. Some physicists have recently declared that time travel is possible. It is a group of scientists from University of Queensland, Australia who came up with a solution that makes time travel a possibility.
The scientists have discovered how time travelling photons behave and that at the quantum level, time travel becomes a possibility. In the study, the scientists have used single particles of light- photons to simulate quantum particles travelling back through time. The study has revealed the strange aspects of modern physics.
Professor Timothy Ralph, a co-author of the study explained, “The properties of quantum particles, are ‘fuzzy’ or uncertain to start with, so this gives them enough wiggle room to avoid inconsistent time travel situations. Our study provides insights into where and how nature might behave differently from what our theories predict.”
In the process of the experiment the researchers have analysed the behaviour of a photon travelling through time that interacted with its older self. Emphasis is laid on the photons that travel through normal space-time and interacts with another photon that is stuck in a time-travelling loop through a wormhole. This process is referred to as, closed timelike curve (CTC).
The theories of special and general relativity, proposed by Albert Einstein reveal that time travel is possible. The special relativity theory proposes that space and time belong to the same thing which is referred to as space- time continuum. Further it states that time has ability to either slow down or fasten up relative to other aspects. The general relativity theory states that time travel is possible by following a space- time path i.e a CTC that reaches it starting point in space at an earlier time.
Martin Ringbauer stated, “The question of time travel features at the interface between two of our most successful yet incompatible physical theories – Einstein’s general relativity and quantum mechanics. Einstein’s theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules.” Martin Ringbauer is a PhD student at UQ’s School of Mathematics and Physics and a lead author of the paper.
In a recent documentary made by BBC astrophysicist Stephen Hawking asserted that it is impossible to achieve time- travel mission as it does not exist as a concept, he believes.Nevertheless, the studies being made on time travel might reveal the possibilities of making time travel a reality.
