From the article...
Quote:
Nothingness, on the quantum level, exists on a level of intuitive absurdity;
statements like this are just dendritically delightful, so to speak.
Besides that the methodologies employed here are fascinating, although a bit tricky to get a firm grasp on.
Physicists may have just manipulated 'pure nothingness'

Question authority. How do you know, that you know, what you know?

I can't imagine/visualize "nothingness".

I have nothing to add.

Speaking from very deep ignorance, I think the real reason some people don't even TRY to understand Quantum Physics is that it really messes with your head i.e. in order to go from one aspect to another you have to accept a whole barrage of things that are mind-blowing anyway.And that only enables you to learn a whole slew of other incredible things. (Or at least, that's how it is for me!)

It can be scary country.

Ancient Greek philosophers argued that if you talk about nothingness, it must be something. So there is no such thing as nothingness.

Sort of like fight club.

I do get 'borrowing something into existence then paying it back' into nothingness. So to me that part does make sense. The rest of it will require some rereading!
I don't agree with the statement that you destroy a quantum system by observing it, though? Surely you just fix some of its properties? It still exists. Think
Have to get my head round 'manipulating nothing' though. Eh?

I'm still working on this part:

Getting a handle on nothingness

How did they do this? Their method essentially involves firing a super short laser pulse lasting only a few femtoseconds (which, if you're counting, is measured on the level of millionths of a billionths of a second) into a "squeezed" vacuum. As the light fires through this vacuum, subtle changes in the polarization of the light can be analyzed to reveal a map, of sorts, of the quantum nothingness.

How does one "squeeze" a vacuum? If it's a true vacuum, what is there to "squeeze"?



We should look to the past to learn from it, not destroy our future because of it — FounDit

I find it beautiful how cutting-edge science practically sounds like magic. I gave up on trying to understand this stuff a while back, way too complicated for me. I love it!

Look, how about this? Let's pretend we've had the row and I've won. See? It saves a lot of effort.

Just look at my signature ;-)

Fine article, Epi. Thanks!

Those not concerned with this line should not unnecessarily get entangled into it. That is my earnest advice.

Now that is another story!

If a particle becomes entangled with a nothingness, then you really have fun phenomena!

As the, probably apocryphal, quote attributed to physicist Richard Feynman goes: if you think you understand quantum mechanics, then you don’t.

Understanding the difficulty of not understanding is not so difficult. Imagine living a 2 dimensional existence, and then try to imagine a sphere… I imagine it as kinda like that. Eh?
