Physicists say Time Travel is Possible Through Parallel Dimensions
It might seem to be something out of a science fiction novel, but physicists have now shown the time travel is possible using parallel dimensions. The report was published in The Sun UK. A group of physicists including Howard Wiseman and Dr. Michael Hall from the Griffith University Centre for Quantum Dynamics believe that there are multiple parallel dimensions or universes. These include parallel timelines. Moreover, these universes also affect each other.
The theory of parallel universes mean that everything that every possible scenario that can happen will happen at some point in some Universe. Professor Wiseman explains
“The idea of parallel universes in quantum mechanics has been around 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 realized — in some universes, the dinosaur-killing asteroid missed Earth. In others, Australia was colonized by the Portuguese.”
We live in a Multiverse?
The concept of a Multiverse has been theorized for long. There are many models that are theorized along the inflation of the universe. The first level of the multiverse says that the universe expands into infinity, beyond our observable universe. The second level theorizes pocket universes. This says that when the universe expanded after the big bang, the expansion was not uniform. This led to the formation of multiple smaller universes that are separated by space.
The final one, the third level of multiverse explain that universes are not separated by space, but by time. Each of these universes have a different timeline, just like we read in science fiction novels. So when you toss a coin, you either get a heads or a tails. According to the level 3 multiverse, both happens, but in different timelines. So, in a parallel dimension, there can be an earth where the dinosaurs never went extinct, or where the World Wars never happened.
