Using photons, Australian scientists managed to create a model in which quantum particles can move back in time<\/b>. As it turned out, the laws of standard quantum mechanics may be violated at the same time.<\/p>\nPhysicists from the University of Queensland<\/b> in Australia set out to simulate a computer experiment, which could prove the possibility of time travel at the quantum level<\/b>, predicted in 1991.<\/h2>\n
They managed<\/a> to simulate the behavior of a single photon passing through a wormhole in space-time in the past and engaging with itself<\/b>. Such a trajectory of a particle is called a closed timelike curve, i.e. a photon returns to the original space-time point and its world line closes.<\/p>\n The researchers studied two scenarios<\/b>. In the first, the particle passes through a wormhole, returning to the past, and interacts with itself. In the second scenario, the photon, forever enclosed in a closed timelike curve<\/a> interacts with another, ordinary particle.<\/p>\n According to the scientists, their work will make an important contribution to the unification of the two great theories in physics<\/b>, which until this moment had little in common: the Einstein\u2019s general theory of relativity and quantum mechanics<\/b>.<\/p>\n \u201cEinstein\u2019s theory describes the world of stars and galaxies, while quantum mechanics studies mainly the properties of elementary particles, atoms and molecules,\u201d said Martin Ringbauer of University of Queensland.<\/p><\/blockquote>\n Einstein\u2019s General Relativity allows the possibility of traveling back in time<\/b> to the object, which gets stuck in a closed timelike curve. However, this possibility can cause a number of paradoxes<\/b>: a time traveler could, for example, prevent his parents from meeting each other, and thus make his own birth impossible.<\/p>\n
