A few years ago I ended up consulting someone over a health matter. This guy seemed to be talking sense, until he started up about ‘quantum healing’. Bad move. You see, I ‘do’ physics.
One of his associates had a machine that used low voltage DC electricity to ‘heal’ by ‘quantum’ effects. This was gibberish, of course, and a brief discussion made clear that (a) the meaning of ‘quantum’ didn’t correlate with anything I knew from the work of Paul Dirac, Niels Bohr, Werner Heisenberg and the rest; and (b) invoking the word, alone, sufficed as a full explanation of how this ‘treatment’ worked.
It was, in short, total snake oil. The science is clear: quantum effects – the real ones – don’t work at macro-level. The end.
That’s why ‘quantum jumping’, ‘quantum healing’ and the rest is rubbish. I don’t doubt that ‘quantum healers’ occasionally get results. The placebo effect is well understood. And maybe sometimes they hit on something that does work. But it won’t be for the reasons they state.
The way quantum physics has been co-opted by new age woo is, I suppose, predictable. The real thing is completely alien to the deterministic world we live in. To help explain indeterminate ‘quantum’ principles, the original physicists offered deterministic metaphors (‘Schroedinger’s cat’) that have since been taken up as if they represented the actual workings of quantum physics.
From this emerged the misconception that the human mind is integral with the outcomes of quantum events, such as the collapse of wave functions. That’s a terribly egocentric view. Physics is more dispassionate; wave-functions resolve without human observation. Bohr pointed that out early on – the experimental outcome is NOT due to the presence of the observer.
What, then, is ‘quantum physics’? Basically, it is an attempt to explain the fact that, when we observe at extremely small scales, the universe appears ‘fuzzy’. The ‘quantum’ explanation for this fuzziness emerged in the first decades of the twentieth century from the work of Max Planck; and from a New Zealander, Ernest Rutherford, whose pioneering experiments with particle physics helped trigger a cascade of analysis. Experiments showed very odd things happening, such as pairs of particles appearing ‘entangled’, meaning they shared the same measurable properties despite being physically separated.This was described in 1935 by Einstein, Podolsky and Rosen – here’s their original paper.
Part of this boiled down to the fact that you can’t measure when the measuring tool is the same size as what you’re measuring. Despite attempts to re-describe measurement conceptually, then and since (e.g. Howard, 1994), this doesn’t seem to be possible at ‘quantum level’. That makes particles (aka ‘waves’) appear indeterminate.
All this is lab stuff, and a long way from new age woo, but it’s what got people such as Einstein, Dirac, Heisenberg, Bohr and others thinking during the early twentieth century. From that emerged quantum physics – specifically, the Copenhagen interpretation, the accepted version of how it’s meant to work. And it does produce results – we’ve built computers that operate via the superposition-of-particle principle. They generate ‘qbits’, for instance, by holding ions in a Paul trap, which operates using radio-frequency AC current – not DC.
The thing is, quantum theory is incompatible with the macro-universe, which Albert Einstein explained in 1917. Yet his General Theory of Relativity has been proven right. Repeatedly. Every time, every test. He was even right about stuff that wasn’t discovered when he developed the theory. Most of us experience how right he was every day – you realise General Relativity makes GPS work properly? Orbiting GPS satellites have to account for relativistic frame-dragging or GPS couldn’t nail your phone’s location to a metre or so.
So far nobody has been able to resolve the dissonance between deterministic macro- and indeterminate-micro scales. A ‘theory of everything’ has been elusive. Explanations have flowed into the abstract – for instance, deciding that reality consists of vibrating ‘strings’. But no observed proof has ever been found.
Lately, some physicists have been wondering. ‘Quantum’ effects work in the sense described – they’ve been tested. But is the ‘quantum’ explanation for those observations right? Right now there are several other potential explanations – some resurrected from old ideas – that will be tested when Large Hadron Collider starts running at full power. All these hypotheses suggest that Einstein was right to be sceptical about the Copenhagen interpretation, which he believed was incomplete.
These new (old) hypotheses make the need to reconcile Copenhagen-style quantum physics with Einstein’s relativistic macro-scale world go away. They also have the side effect of rendering new age ‘quantum’ invocations even more ridiculous. More soon.
