Nugatory replied to the thread Undergrad Bell's theorem and measurements not done.To evaluate that we have to look at the detailed construct of the real non-idealized experiment This would be an example of the fair... -
Nugatory replied to the thread Undergrad Bell's theorem and measurements not done.It is clearly valid to assign values to unmeasured properties of large objects and it was something of a surprise that unmeasured...

Nugatory replied to the thread Undergrad Bell's theorem and measurements not done.It’s a proof by contradiction argument. The calculation is correct if the realism and locality assumptions hold; we do the experiment...

Nugatory reacted to Ibix's post in the thread High School Is it possible for matter to be completely destroyed to nothingness with
Like.
The answer to question 1 depends a bit in what you accept as "nothingness". The most complete destruction I can think of is to mix... -
Nugatory replied to the thread High School Is it possible for matter to be completely destroyed to nothingness.#1: if we expose ashes (or anything else, for that matter) to sufficiently high heat it will boil away into hot gas - but that’s still...

Nugatory replied to the thread Undergrad Question about entanglement and relative causality.I cannot prove that that claim is wrong, but that doesn’t mean that I have to accept it. Causality is such a useful organizing...

Nugatory reacted to Dale's post in the thread Graduate Is Energy conservation among sectors (EM,GR,QM) a principle? with Like.
Again, there is no single answer. Any author can choose whether they take it as an assumed principle or a theorem proven from other...

Nugatory replied to the thread Undergrad New EM spectrum designation between UV and X-rays.There's a fair amount of historical and biological accident in how we label the various ranges of the electromagnetic spectrum: for...

Nugatory reacted to Ibix's post in the thread High School Do Dark Energy and the Casimir effect indicate Exotic Matter could exist? with Like.
Your intro thread says "18 y/o physics enthusiast". Special relativity should be well within your reach - you'll need calculus if you...

Nugatory replied to the thread Undergrad What empirical observation supports the axiom of continuous spacetime?.The claim that quantum mechanics requires any ontology is a philosophical claim, not a physical one. All the physics is in the...

Nugatory replied to the thread Undergrad Questions: Multi-particle entanglement, speed of light, electron orbitals.The quickest way to get someone to take a look is to report the thread, but now that I've seen this post from you I can take care of it.

Nugatory replied to the thread Undergrad Questions: Multi-particle entanglement, speed of light, electron orbitals.Yes. Just about any system of multiple interacting particles will be entangled in some way. It’s more than “generally accepted”, it is...

Nugatory reacted to Dale's post in the thread Undergrad What empirical observation supports the axiom of continuous spacetime? with Like.
No, this is not true. Some do, but not all. On the contrary, every observation which is correctly predicted by a theory which uses...

Nugatory reacted to PeterDonis's post in the thread Undergrad What empirical observation supports the axiom of continuous spacetime? with Like.
Discreteness of what, though? Let's take the cases you give: Even leaving aside that there are arguments in the literature against the...

Nugatory reacted to Astronuc's post in the thread Hantavirus outbreak aboard ship MV Hondius; virus present in Argentina with Like.
Several days ago, an outbreak of Hantavirus was reported aboard cruise ship MV Hondius, which apparently set sail from Argentina. Ref...
