Andrew team members Professor rust walcott and Roman Dr Card base prioritized using laser improvement 'double slit experiment'. They launch the helium atom, let it through the first line of the laser grating, and to measure if the name of the second grating appear, whether helium atom state changes.

in the standard of 'double slit experiment', the photons through a single slit, its behavior shows characteristics of particles ( Above) ; When the second slit introduced, it can produce interference light, which is a typical phenomenon of photons in the form of wave forward ( The figure below) 。

according to foreign media reports, in the modern physics, it is a core principle, only in a direction that is light, which can be only in the past affect the future, but the future could not affect the past. But, at the Australian national university scientists recently found by experiment and the quantum energy levels, the core principles may not work. Researchers think that this means that future events can affect what has happened, that time can move forward, can also be driven back.

at the Australian national university research team to the strange behavior of particles in quantum mechanics were studied. In the quantum world, a moving object may also exist in two states, namely particle and wave. At the same time, however, we can't see the two of them. This is because when scientists try to observation of visible photons or fast moving atom, or to particles, or take the form of wave.

however, recently in the research team of experiments, scientists have discovered a strange phenomenon. When they tried to observe an atom to make sure they see whether in the form of wave still exists in the form of particles, the spectacle phenomenon happened. Research team leader, the Australian national university physicist Andrew , 'said the rust walcott is introduced in the quantum energy levels, if you don't look at it, the entity does not exist. These atoms do not move from A to B. Only at the end of the journey to their observations, wave or particle shape of their behaviour. '

the scientists' study, published in the journal nature physics. The experiment is to create famous quantum physicist John Wheeler in 1978 put forward the theory of ideology, namely 'delay choose thought experiment'. 'Delay choose thought experiment' is actually 'double slit experiment' improved version, namely the light through the slit on the curtain wall. When a beam of light through a slit exposure to the back of the wall, the photons seem to show the particle behavior. When introducing the second slit, will show light interference, the photon nature seems to have fluctuated. John - Wheeler suggestion behind the first side wall and increase the second face with a slit in the curtain wall, the purpose is to want to take a look at the light through the two walls at state can remain stable. But, so far, it seems unlikely that the experiment is complete.

at the Australian national university research team - to John Wheeler's thought changed slightly, make it possible for the experiment. Instead of using photons, they used helium atom, let it pass through grating formed by laser beam, rather than through the physical curtain wall. Such that when the speed of atoms through the second checkpoint when the researchers can accurately observed it what happened. The researchers found that if there is no the second grating, atom is along a single line, behavior and particle. But when there are two grating, atoms along the routes, some ways of behaving as a wave.

before the introduction of the second grating, the researchers of helium atoms through the first grating lines were measured. Experiments found that has not yet been introduced but could introduce the name of the second grating made an impact on the state of the particle. Andrew explained. 'this suggests that if the helium atoms along a certain route, the measurement results of the future will affect the lines of the atom. 'According to the researchers, this suggests that future events are affecting the atoms in the past.
