Do you believe in the double slit experiment?

Asked by luigirovatti (1526points) 3 weeks ago

I read it mentioned in “The Flicker Men” by Ted Kosmatka. Then, I researched it, and found it in this article:

The question is, is it real? Do we believe it? And what does it do?

What do you mean? Of course I believe in it. It’s been done a zillion times. It is the reason light must be regarded as both a wave and particle, a fundamental of high school physics for at least 300 years.

@stanleybmanly: Yes, but even though the results have been tested and retested, they lack an intuitive base from which to extrapolate. Quantum mechanics, to some extent, is a descriptive science. It can be used to predict phenomena, and yet at its core, what it says about the macro world remains unclear. This is perhaps why there are so many different interpretations, so many different theories about what is really going on behind the curtain. That book is simply one of those theories.

If I would see it I wouldn’t believe it.
Otherwise, I am.

So what? The question “do you believe it?” Is useless. Quantum effects are real. Whether it makes sense or not is immaterial to the 200 year demonstration that they are as real as reality itself. I’m forced to “believe in them”.

It gets much stranger when you look at the results of the delayed choice quantum eraser experiment.

Science is based on experimental verification, not intuition. Is it intuitive that nothing can go faster than the speed of light or, to go back a few centuries, that in a vacuum small objects fall just as fast as large ones?

Scientific properties are not just curiosities. They are used in practical applications. Quantum properties are used in designing computer chips and general relativity is used in GPS devices. One can view the non-intuitive results of science as a mark of the success of scientific method.

It isn’t a matter of belief. It’s a fact.

Science doesn’t care what you believe. As others note above the wave-particle behavior of light is a demonstrable fact not something you need to believe in and not something that will change at all depending on whether or not you believe in it.

@luigirovatti What your experience of this phenomenon tells you is that our human senses are not equipped to see/know what is going on. We just didn’t evolve to perceive that kind of thing. This sort of thing is a good example of how important and clever tools are that humans use to “see” things that we cannot see without them.

Most of quantum mechanics is like that, counter-intuitive or incomprehensible, but we rely on what has been discovered about quantum mechanics every day (e.g. all our computing gadgets with transistors in them).

Several scientists discuss, regarding ‘extra’ dimensions, that it is likely there are all kinds of phenomena happening in those extra dimensions all around us all the time but we are physically equipped to know about only the usual three and a half dimensions of our normal consensus reality (3D plus time).

The double slit experiment proves at least 1 of 2 things is true:

(A) “Nature is very weird, and unintuitive.”
(B) “You’re living in a Matrix and the double slit experiment is repeatable proof of flaws in the code.”

@Caravanfan that is a common response to most scientific evidence these days.
