According to a theory in quantum mechanics, our lives are just an illusion as the universe doesn’t exist if we stop looking at it, or in other words reality does not exist until it is measured
The famous theory in quantum physics argues that a particle’s past behaviour changes based on what we see.
Now, a new test has been performed by scientists using an atom and laser beams, which they say proves this theory to be true.

According to the rules of quantum mechanics, the boundary between the ‘world out there’ and our own subjective consciousness are blurred.
When physicists look at atoms or particles of light, what they see depends on how they have set up their experiment.
To test this, physicists at the Australian National University recently conducted what is known as the John Wheeler’s delayed-choice thought experiment.
The experiment involves a moving object that is given the choice to act like a particle or a wave.
Wheeler’s experiment then asks – at which point does the object decide?
Common sense says the object is either wave-like or particle-like, independent of how we measure it.
But quantum physics predicts that whether you observe wave like behaviour or particle behaviour depends only on how it is actually measured at the end of its journey.
This is exactly what the Australian team found.
‘It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it,’ said Associate Professor Andrew Truscott.
Despite the apparent weirdness, the results confirm the validity of quantum theory.
Quantum theory governs the world of the very small, and has enabled the development of many technologies such as LEDs, lasers and computer chips.
The ANU reversed Wheeler’s original concept of light beams being bounced by mirrors, and instead used atoms scattered by laser light.
‘Quantum physics predictions about interference seem odd enough when applied to light, which seems more like a wave,’ said PhD student Roman Khakimov.
‘But to have done the experiment with atoms, which are complicated things that have mass and interact with electric fields and so on, adds to the weirdness.’
Professor Truscott’s team first trapped a collection of helium atoms in a suspended state known as a Bose-Einstein condensate, and then ejected them until there was only a single atom left.
The single atom was then dropped through a pair of laser beams, which formed a grating pattern that acted as crossroads in the same way a solid grating would scatter light.
A second light grating to recombine the paths was randomly added, which led to constructive or destructive interference as if the atom had travelled both paths.
When the second light grating was not added, no interference was seen as if the atom chose only one path.
However, the random number determining whether the grating was added was only generated after the atom had passed through the crossroads.
If you choose to believe that the atom really did take a particular path or paths then you have to accept that a future measurement is affecting the atom’s past, said Truscott.
‘The atoms did not travel from A to B. It was only when they were measured at the end of the journey that their wave-like or particle-like behaviour was brought into existence,’ he said.

I feel this did not “prove” anything of the sort, but rather shows a lack of understanding of how things work on a quantum level. Basically, multiple possibilities exist at the same time. The determination that it is a certain state is only because us poor humans cannot see the multiplicity and only recognize the final state upon completion. In essence, you have picked which reality you are part of. You have not influenced the outcome simply by observing it. To me this is a major flaw in the thinking behind the Copenhagen theory.

All Perception! Nothing has exist.

The blind man travels through a water sprinkler spray the first time without getting wet but as a prank I will observe him on his return at the last moment. Does his reality play out or does my observation expectation play out or both simultaneously play out and both realities fracture into their separate alternate universes or simulations?

Go find a nice big rock. Stand in front of it. Close your eyes and KICK it ! Then tell me you believe this BS ! LOL !

What this actually proves is that even scientists are capable of making errors in logic.
