If the virtual particles exchanged to create forces don't really exist, then what are forces made of?

Posted: 27 Jun 2017 05:09 AM PDT

Hi, other /r/askscience posts I've read, such as this one, and this comment seem to imply that the virtual particles that are supposedly exchanged are more mathematical abstractions than literal objects. If that is the case, what are forces made of?

I know that the sky is blue because our atmosphere scatters higher frequency wavelengths of light, but what happens specifically on a molecular level in the scattering process?

Where do bugs like Fireflies go during the 9 months of the year that I don't see them?

Posted: 26 Jun 2017 07:02 PM PDT

This goes for any seasonal insect, I guess. Are there eggs just sitting around on the ground during fall and winter waiting for spring before hatching? Are there any bugs alive during non-seasonal months? Do they migrate?

Why is the helium-4 nucleus (an alpha particle) unusually stable among lighter nuclei?

I know it has something to do with "magic numbers", but I don't really understand know about that also.

Is it possible to achieve absolute darkness ?

Posted: 26 Jun 2017 11:17 PM PDT

Is it possible to achieve absolute darkness , as in no photons emitted across the whole spectrum of light (not only visible light ) or does that requires absolute zero temperatures due to black body radiation?

Why companies can't chemical ananalyze, for example, Pepsi, and produce identical mixture on their own?

Posted: 26 Jun 2017 09:03 AM PDT

I believe some things are patented out - but then are not a secret. For example WD-40 oil is not patented and its recipe is secret, why people just don't analyze it's contents to produce a copy and gain huge cash?

Are there 'superbugs' in animals?

Posted: 27 Jun 2017 05:00 AM PDT

Hi all, I'm just trying to explore how antibiotic resistance can affect the ecosystem. I understand that animals can increase antibiotic resistance by passing on resistant bacteria into human food.

In that case, can animal species have superbugs like humans do? If so, are there animal species that are being ravaged at the moment?

About the Cognitive Ease Experiment on pg.70 of "Thinking, Fast and Slow", what does Daniel Kahneman mean by "emotional changes are NOT linked causually to the words"?

Posted: 27 Jun 2017 03:59 AM PDT

English is not my first language so please bear with me.

So I have been reading this book for some time now and found a great deal of interesting information about how the mind works. There is this particular section that I am having trouble trying to understand however. The text is as followed:

Cognitive ease and smiling occur together, but do the good feelings actually lead to intuitions of coherence? Yes, they do. The proof comes from a clever experimental approach that has become increasingly popular. Some participants were given a cover story that provided an alternative interpretation for their good feeling: they were told about music played in their earphones that "previous research showed that this music influences the emotional reactions of individuals." This story completely eliminates the intuition of coherence. The finding shows that the brief emotional response that follows the presentation of a triad of words (pleasant if the triad is coherent, unpleasant otherwise) is actually the basis of judgments of coherence. There is nothing here that System 1 cannot do. Emotional changes are expected, and because they are unsurprising they are not linked casually to the words.

-- page 70, "Thinking, Fast and Slow", Daniel Kahneman

What does he mean in the last sentence?

I understand that the participants were led to think that the music played was the only agent that affected their mood. I also understand that their System 1 was fully engaged because the participants expected some emotional changes along with the music playing to their ears; i.e., they feel safe and their System 2 has no influence here.

What I don't understand however is how their emotional changes are NOT linked casually to the triads of words. Didn't he just say earlier that the triads of words (their coherence) caused pleasant or unpleasant responses on the participants?

Why do batteries catch fire when you take them apart?

Posted: 26 Jun 2017 10:29 PM PDT

I've been watching some electronic hobbyist videos on YouTube and I'm curious as to why batteries seemingly explode when they are opened up.

How are ccv codes on the back of credit cards so secure?

Posted: 27 Jun 2017 01:10 AM PDT

How are those three digits on the back secure enough to prevent fraud using just the front numbers? They're just an algorithm, right? How have people not figured out the algorithms and then used that knowledge to vomit fraud with just the normal cc number, or even more so how have people not created credit card generators that give you a cc number with a matching ccv?

Are there any studies that compare the levels of "death acceptance" between terminal patients with and without descendants?

Posted: 26 Jun 2017 08:50 AM PDT

Sorry for possible /r/titlegore.

The commonly-held evolutionary explanation for the desire to have sex and procreate is the need to pass on one's genes. I'm wondering if there's ever been a study that measured how "at peace" terminal patients were with their impending death based on whether not they've already passed on their genes (ie, parents, grandparents etc. are more accepting of their demise than childless patients, because the former group "lives on" through their descendants).

If so, what were the results?
