Quantum Physics is finally proving to us that reality does not exist until someone looks at it!

 Quantum Physics is beginning to get a lot of attention recently. Films are being based on quantum theories, experiments are becoming more openly plugged on social media and TV, and it seems like most people are opening up to the idea that things are not really as we see them in reality .

One of the most famous theories which has been hovering around for some time now is that reality does not actually exist until it is measured. Quantum Physics suggests that reality doesn't exist until someone physically looks at it. In the past when scientists have spoken about this theory the majority of people have laughed it off and persuaded themselves that this is not the case and could not possibly be true, but now some of those very same people are coming back to talk more about the theory and seem a lot more open minded about it and obviously more interested.

Back in 1978 John Archibald Wheeler carried out a series of thought experiments known as the Wheeler's delayed choice experiment. The purpose of these experiments was to try and determine whether photons adjusted their state on demand or if they never had a state to begin with. Thinking logically you could say that light is either made up of particles or waves but not both, this is Quantum Physics we are talking about though, and that doesn't quite work out. During the experiment mirrors were used to reflect light beams which were then measured, it was a hard experiment to perform in those days due to our lack in technological understanding  and apparatus, but Wheeler was quite certain that the light had neither state until the act of observing occurred and determined whether the photon would act as a particle or wave.

Since that time many different types of experiments have been carried out with more modern technology aspiring  to finally proving that reality does not exist until someone observes it. There is already a well known classical Quantum Physics theory that the universe does not actually exist if no one observes it, and this is one of the things that scientists are trying to prove or disprove. One of the most well known experiments is the Double Slit Experiment, an experiment that has been repeated and repeated over the years, and always has the same conclusion.
"Another well known experiment is the Double Slit experiment, this experiment has been carried out many times by scientists world wide and always ends with the same results. Basically particles are fired at a screen which is blocked by a wall with two slits, you would expect that as the particles were fired at the screen, they would only land on the screen in between the holes in the wall, but this is not the case. The particles hit the wall the same way as a wave would, if you imagine water flowing through the slits you would see ripples that hit the screen in multiple places including the places blocked by the wall, this would suggest that particles are actually waves, but that isn't possible right? ;)"

More recently the experiment has once again terminated that at sub atomic levels, reality truly does not exist until it is observed. Scientists at the National University of Australia recreated Wheeler's delayed choice experiment, but this time used helium atoms that were scattered using lasers. Once again the experiment was a success, they created a grating pattern using 2 lasers. Then fired an atom through it, once it had passed the first grating, a second grating was generated in its path. When the second path was added there was interference measured which showed the atom have travelled through both paths acting like a wave, but when the grating hadn't been added there was no interference meaning that the atom had only travelled one path acting like a particle.

Physicist Andrew Truscott stated:

"Measurements are important. This basically proves that measurement is everything. On a quantum level, what we know as "reality" doesn't really exist if you are not looking at it."

"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,”

"If one chooses to believe that the atom really did take a particular path or paths then one has to accept that a future measurement is affecting the atom's past,"


This new round of evidence will probably not be anything shocking to many people, and to people who are just finding out about this now, it should be an intriguing wake up call. Whatever you choose to believe about the subject it still stands that this has been proven, now we can look forward to more findings that will come in very near future  as we need to continue to disentangle the true power of our universe and find the answers to questions that have held back the human race for so long. Again to quote one of the most famous quotes in the world of Quantum Physics media from the film the Matrix:

"What is real? How do you define real? If you are talking about what you can feel, what you smell, what you can taste and see, then real is simply electrical signals interpreted by your brain."
