Mordred has earned 'respect' from many of us on this forum. It seems the jury is still out on you; but you do show hope,and I value ( most ) of your contributions 🙂 . Don't be obsessively stubborn and blow it.

Wow. Talk about 'throwing stones' when you live in a 'glass house'.

I feel your pain, Studiot. Most times these posters ask questions easily answered by a google search, or 'pepper' their post with scientific buzz-words which they think mean something else. I usually tend not to reply to those posts, and hope the thread dies a quick death. If feeling particularly bored I might reply with attempted humor, but I really hate it when those types of threads go on for many pages, and no one learns anything from them. Sometimes it gets so bad I don't post anything for several days.

On the other hand,charge migration with the extremely small feature size, and multi-level cells, of modern SSDs, necessitating cell redundancies, and various error correction algorithms for on-the-fly swapping of failed cells, makes the premise that SSDs are more durable than spinning magnetic drives questionable. Current consumer SSDs use quad level cells to store 16 bits of information per cell, and are extremely prone to charge migration. Enterprise SSDs, used in data centers, are usually restricted to 2 level cells, and are much more expensive.

To put it in layman's terms ... Gravitational waves are the 'ringing' of space-time ( outside any possible event horizon ) from the inward spiral/collision of two or more massive objects. Not only Black Holes, but neutron stars, white dwarfs, and even bowling balls ( but would be undetectably weak ). As for 'infinities' and other timings related to Black Holes, your frame of reference matters, and we have different names for these timings depending on who is doing the observing. ( see Markus' explanation for more detail ).

I'm with Studiot on this, Erik. I have been re-reading the threads you participated in, concerning Gravity theory and fine tuning of the Universe, and I found your posts to be thoughtful and insightful. Even when making statements that others corrected, there is no need for editing, as they become a valuable learning tool for others. And that is the reason we are all here; to learn from others, and sometimes, provide some insights, or even teach a thing or two to the 'experts'. Your contributions, so far, are valued and appreciated.

At first I thought this was a violation of isotropy and homogeneity, indicating the universe has a 'drection', but on reading the link, I realized it is another ( of a few ) parity violations. Who knows, investigatng the cause of this effect at the earliest moments of the Big Bang, may shed some light on why the current universe is predomiinantly matter, and almost devoid of anti-matter. ( but I doubt it )

You suggest that the 'stick' of sanctions and retaliation is ineffective because it only affects the common people, while the despots and their oligarchs are insulated against them. You suggest the 'carrot' approach of diplomacy and negotiations, but why would the despots negotiate if you don't have any leverage ( lack of 'stick' ) on them ? What you are in effect proposing is appeasement. Give away parts of Ukraine, and have her people enslaved for your 'peace of mind'. And this will work exactly the same next time V Putin wants to annex more territory. Not everyone who does 'evil' things does so because they are hungry or oppressed. There are evil people in this world ( not on yours ?? ). Of all the evil people of the last century, Mussolini, Stalin, Mao Zedong, Pol Pot, Putin and KJU, all looked well-fed to me; maybe Hitler could have used a sandwich.

Peterkin is a zombiophobe ! 😄 😄

Ah, but he did provide evidence, Swansont ... His dumb, uninformed post is evidence that it is happening.

I know exactly what you mean. Those Nazi Ukrainians, and their jewish President, will stop at nothing in an effort to implicate those innocent Russian victims and make them look bad in the eyes of the World. Those well-intentioned Russians should just leave the Ukraine to their evil ways, and stop trying to help and denazify them.

Is this a belief, or can you suggest a way to prove it ?

But that is exactly what we're dealing with; nothing other than fields on top of fields. Whether scalar ( value at a point ), vector ( value and direction at a point ) or even tensor ( for that pesky gravity field ), QFT is governed by Heisenberg, and so values at a specific point cannot be exact. These small 'ripples' in the quantzed fied values must meet a certain threshold; below that threshold they are 'virtual', and if surpassing the threshold, they are 'real'. It is foor convenience that we treat these field excitations as quantum particles. See the sticky in Quantum Theory "Matter is excitations in a field" It i

Why do I picture your house to look like Dr Emmett Brown's house ( from Back to the Future ), Sensei ?

So, unless the interaction of an entangled particle, with its partner, 'fixes' the particular state of the entangled property, the system has no reason to decohere. It is only when the interaction with the entangled partner results in a defined state ( even if we don't know it ? ) that entanglement is lost. Makes sense; thanks Markus.

And my point is people have to be responsible, and be held accountable, for their actions/decisions. Especially when those actions/decisions result in hundred thousands of deaths and whole countries destroyed through no fault of their own.

That's the thing about quantum particles, we can't determine much about them before detection/interaction; they are simply a mathematical expression of probability distributions. And, upon detection, their properties ( wave-like or particle-like ) depend mostly on the detection mechanism. As a result, we have various models which must be applied to differing circumstances.

The 'wall' was referencing Markus' observation that whereas quantum particles can pass through a wall, as opposed to classical particles which cannot, some of us are thinking 'classically', and nothing is getting through. The question originally posed is, regardless of the mechanism for doing so, can a quantum particle lose coherence by interaction with its entangled partner ? Or does the common wave function alreadytake the interaction into account and simply 'updates' itself ?

We are discussing Russia's invasion of the Ukraine and the ensuing bloodshed and destruction. V Putin was not s'scared' when he launched the invasion; he thought it would be a cake-walk and over in a couple of days. To claim that he is a 'scared little boy' now that the tables have turned is absolving him of the evil decisions he previously made. Should a gambler who bets it all, thinking he'll win big, be given his money back now that he's impoverished ? Tell it to your bookie.

I'm afraid INow might suggest some sci-fi porn ...

Centrifugal force is a fictituous force made apparent by motion in a rotating frame of reference. If you have no access to the external stationary frame, or the motion is slow enough that it is hard to detect, there will be nomotion sickness. IIOW, if you cannot see outside the rotating tube providing artificial gravity, or the stars are far enough away that motion is hardly noticeable, there is no problem.

I don't know how we got on the subject of light cones, and I don't want to re-read to find out. Essentially light cones define which points in space-time have been, are, and will be, in causal contact with an event. Causal contact has a very specific meaning in Physics, and is subject to the speed of light, c .It implies cause and effect, the very things Bangstrom is arguing against, as non-locality requires an 'effect' before information about the 'cause 'can reach that point The 'slope' of the light cone itself is c , and separates time-like ( causal ) from space-like ( non-causal or superluminal ) events in space-time.

It may be an example brought to an absurd level, but it illustrates perfectly that QM says there is no reality until an observation/interaction is made. Which side of the wall are you on ? One thing I've always wondered about, and maybe you more learned gentlemen can offer some guidance ... If I produce two entangled particles, and somehow manage to 'steer' them towards each other such that they interact ( only ) with each other, is entanglement lost ?

Old Westerns. Specifically Sergio Leone 'spaghetty' westerns. ( what were you expecting ? )

That 'work together' part would be an excellent start ... after that, sky's the limit.
