Reality Doesn’t Exist Until We Measure it: Quantum Experiment Confirms




Last year, Australian scientists replicated a classic  experiment confirming  that reality doesn’t actually exist until we measure it, that is, at the quantum level.

“It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it,” lead researcher and physicist Andrew Truscott said in a press relase..

The replicated experiment is known John Wheeler’s delayed-choice thought experiment, the experiment was first proposed back in 1978 using light beams bounced by mirrors, but back then, the technology needed was pretty much impossible. Now, almost 40 years later, the Australian team has managed to recreate the experiment using helium atoms scattered by laser light.

The delayed choice experiment illustrates how what happens in the present can change what happens(ed) in the past. It also shows how time can go backwards, how cause and effect can be reversed, and how the future caused the past. We published an article that goes into detail about it,.

Quantum physics predictions about interference seem odd enough when applied to light, which seems more like a wave, 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,” said Roman Khakimov, a PhD student who worked on the experiment.

To  recreate the experiment, researchers  team trapped a bunch of helium atoms in a suspended state known as a Bose-Einstein condensate, and then ejected them all until there was only a single atom left.

The chosen atom was then dropped through a pair of laser beams, which made a grating pattern that acted as a crossroads that would scatter the path of the atom, much like a solid grating would scatter light. After that, researchers randomly added a second grating that recombined the paths, but only after the atom had already passed the first grating.

When this second grating was added, it led to destructive interference, which is what you’d expect if the atom had travelled both paths, like a wave would. But when the second grating was not added, no interference was observed, as if the atom chose only one path.

The fact that this second grating was only added after the atom passed through the first crossroads suggests that the atom hadn’t yet determined its nature before being measured a se

cond time.

So, if you believe that the atom did take a particular path or paths at the first crossroad, this means that a future measurement was affecting the atom’s path.

“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,” – Andrew Truscott

 “This quantum uncertainty is defined as the ability, “according to the quantum mechanic laws that govern subatomic affairs, of a particle like an electron to exist in a murky state of possibility — to be anywhere, everywhere or nowhere at all — until clicked into substantiality by a laboratory detector or an eyeball.”


Another potential revelation of this experience is that “the observer creates the reality.”  Because it is a form of measuring, and a factor associated with consciousness. A paper published in the peer-reviewed journal Physics Essays by Dean Radin, PhD, explains how this experiment has been used multiple times to explore the role of consciousness in shaping the nature of physical reality.


In this experiment, a double-slit optical system was used to test the possible role of consciousness in the collapse of the quantum wave-function. The ratio of the interference pattern’s double slit spectral power to its single slit spectral power was predicted to decrease when attention was focused toward the double slit as compared to away from it. The study found that factors associated with consciousness “significantly” correlated in predicted ways with perturbations in the double slit interference pattern.

“Observation not only disturbs what has to be measured, they produce it. We compel the electron to assume a definite position. We ourselves produce the results of the measurement.”

I’ll leave you with this one last quote to give you something to think about

“A fundamental conclusion of the new physics also acknowledges that the observer creates the reality. As observers, we are personally involved with the creation of our own reality. Physicists are being forced to admit that the universe is a “mental” construction. Pioneering physicist Sir James Jeans wrote: “The stream of knowledge is heading toward a non-mechanical reality; the universe begins to look more like a great thought than like a great machine. Mind no longer appears to be an accidental intruder into the realm of matter, we ought rather hail it as the creator and governor of the realm of matter. Get over it, and accept the inarguable conclusion
