One such odd feature is that, according to quantum physics, the act of observation changes the universe. An unobserved event, according to quantum lore, has neither happened nor not happened: it exists as a mathematical object called a wave function, which describes all possible versions of realities, and which only breaks down into one or other when we make an observation.

Today I read an article which gives some insights into quantum physics and here are some excerpts:

 

Quantum theory, which measures the truth of what we perceive to be real, is nearing a landmark moment in its history.

Cats that are both dead and alive, atoms that “know” when you are staring at them and parallel worlds that harbour any and every possibility: quantum theory has always thrown up some bizarre ideas. Now, for the first time, it may become possible to test one of its very strangest.

Quantum theory is the most successful framework for understanding the universe that we have, providing predictions that are borne out to a stunning degree of precision. But there’s a problem: no one actually knows how to interpret it. Albert Einstein, one of its architects, spent much of his life plotting its overthrow, because of the peculiar picture of reality – or “spookiness”, as he liked to put it - that it revealed.

One such odd feature is that, according to quantum physics, the act of observation changes the universe. An unobserved event, according to quantum lore, has neither happened nor not happened: it exists as a mathematical object called a wave function, which describes all possible versions of realities, and which only breaks down into one or other when we make an observation. A molecule may actually exist in what is called a “superposition”, which means an impossible coexistence of apparently contradictory possibilities, being both a dot-like particle and a wave that ripples over a distance some 1,000 times greater.

To come up with a more tangible example of just how odd this view of reality is, Erwin Schrödinger devised a thought experiment in 1935 starring a cat that is neither dead nor alive. Only when we take a peek inside the box does the wave function “collapse” into one actuality: there is either a dead cat, or a live one. This model of reality is known as the “Copenhagen Interpretation” - but not all physicists accept it. Some claim that the very act of observation causes the universe to split: I see a live cat, but in another universe, a different me sees a dead one. This is the so-called “Many Worlds” interpretation, which dates back to 1957.

If we’re honest, most scientists simply ignore this issue - first, because they’re as baffled as the rest of us, and second, because however you interpret it, the current mathematics of quantum theory gives the right answer, and it has long been assumed that there is no experiment that can determine which, if either, interpretation was right. Hence the third interpretation: “Shut up and calculate!”

Now, there is finally a prospect of lifting this debate beyond dry philosophy by actually testing the GRWP proposal, with the help of a clever experiment devised by Markus Arndt’s team at the University of Vienna (in collaboration with Klaus Hornberger in Duisburg).

 

The author of the article I just quoted from is the editor of a science magazine and therefore deals with scientists and their writings and their attitudes and he writes that most scientists ignore this issue, the issue being aspects of quantum physics. He says they are baffled as the rest of us. They simply ignore an important finding. And they do the same with other findings which are important, for instance findings of spiritual nature. But they call themselves scientist, people who know, but they ignore important aspects of life. So this article gives some interesting insight into what is going on in the world of science, the search for truth certainly does not seem to be an important aspect of their work.
