Yes I get that there are often no answers to why questions, as you outline, but in this case I was not so much asking for why there is this relationship between momentum and wavelength, but rather what physical manifestation this might have ?
While the mathematics and the experimental results of de Broglie's equation are clear, what is the best understood explanation as to what is happening in underlying reality of why wavelength varies (inversely) with momentum for all energy and matter ?
I've been reading Brian Greene's "The Fabric of the Cosmos" and am currently at the description of the delayed choice quantum eraser experiment. My understanding is that this can be set up so that the idler photons can be measured (long) after the signal photons hit the detector screen. Under...
Is it possible that the reason the delayed choice two slit experiment outcomes occur is because for the photon, traveling at the speed of light, the past, present and future are all as one, and therefore it "knows" what is going to happen and therefore always "makes the right choice" at the...
Thanks - but the observer I was referring to was not falling in with the object, but rather was watching from a distance. So in particular if a black hole is formed by a collapsing star, from the perspective of the rest of the universe does the black hole ever form? (I understand that from the...
Is it correct that, from the perspective of an observer, time slows down and ultimately stops at the event horizon of a black hole, implying that no black holes have had time to form in the universe ?
As I understand, two electrons may be found (close) together providing they are of opposite spin. How does this occur ? How does the character of opposite spin offset the impact of the electromagnetic force repelling these two particles of the same charge ?
While the distances are clearly too small to matter practically, conceptually are quantum interactions (eg force carrying particle exchanges) occurring at the speed of light ? And are there any dilation issues at play ?
I am having a bit of trouble with understanding a basic point re the concept of relativity of simultaneity. I get the point of observers seeing events at different times, due to the passage of time of light traveling to them from the event. But I don't understand why this precludes events being...
I'd appreciate some explanation on how does one understand/reconcile the seemingly alternative concepts of gravity as (i) due to the warping of space by matter vs (ii) the exchange of gravitons. Is the latter a construction of how gravity can be considered within a quantum mechanics framework ...
What is the underlying feature of general relativity that, unlike Newtonian mechanics, results in the correct calculation of orbits i.e. including precession (e.g. Mercury). I not asking for the mathematics (i.e. the additional term in the equation) but rather what underlying "physical"...
