Hehe, that’s some top level spaghetti. Remember, space is cheap! It’s easier to keep it nice when there’s plenty of space around everything.

Wasn’t he more criticizing the scale? Like, a sith warrior is great, but he can’t really compete with the power of the Death Star when it comes to sheer scale. Just ask Alderaan.

Arguably it is better than mining for coal, lithium, etc. since those have similar issues, but one gram of uranium contains energy similar to 3 tons of coal.

Fairly so - it isn’t emissions, and does not contribute to the problem in a meaningful way.

The reason why emissions are dangerous is because they trap solar heat at large enough scales to change the global climate. Server farm heating isn’t really anywhere near contributing at that scale.

Ah yes, sorry, I’ve corrected my comment to micrograms.

You can eat it just fine, just don’t eat it regularly for a long time.

An ounce of their Dark Chocolate has 134% of the California MADL dose of 0.5 micrograms of lead, for those wondering about details.

They don’t have an army, true, but the reason they don’t need one is that they are a part of NATO, and are exempt from the requirements of contributing to NATOs standing forces in return for providing facilities and land to the alliance.

So Björk is being at bit disingenuous. It’s not like the Icelanders are a shining beacon of pacifism and diplomacy, they’re just part of a big military alliance.

What on earth are you talking about?

There’s nothing easier than just explicitly checking in whether you’ve read the signals correctly or not before making any creepy moves.

Tip #1 for flirting: Make sure that the other person has a very easy way out of anything they might not like. Then you know they’re enthusiastically consenting for whatever comes next.

Solid matter physics would be a more straightforward name - it’s just the physics of matter that isn’t liquid or gas, which usually means crystals.

I like using it for collages and memes - the magic cutout plus the 3D tools made it really easy to edit things together quick and dirty.

Weird that the text was re-written, I wonder if the comic was somehow translated and translated back to English?

The “message” does not have any local effect on reality - when you measure your particle, you have no way of figuring out if its partner was already measured elsewhere. The effect it does have is on the global state, maintaining the correlation that was encoded from the start.

If you write up the density matrix for the system before and after measurement of one of the particles, you can see that while the density matrix changes, it does not change in a way one can measure.

What I will concede is that before the first measurement the global state is |00>+|11>, afterwards it is |00> or |11>. This projection appears to happen instantaneously, no matter the distance, which is indeed faster than light.

But calling the wave function collapse a signal or a message or a transfer of information is misleading, I would say. In your example, we know that the initial state is |00>+|11>, and that the result of the first measurement is then, say, 1. Then no further information is required to know that the other measurement will result in 1. No messages required, no hidden variables, simply the process of elimination.

I would like to say that this is indeed a confusing subject, but that the math is clear, and that I am arguing what is my impression of the mainstream view in the field.

I fully understand the concept of entanglement and the experiments you mention, but I’m still to understand what you mean when you say “something” is being transmitted between the particles.

As you say, this “something” cannot contain information, and it also cannot influence the particle physically, since there is no way to distinguish the physical state of the particle before and after it receives this “something”. So the signal contains nothing, and has no effect on physical reality. That sounds a lot like “nothing” rather than “something”.

I completely get the argument that somehow the two particles must agree on what result to give, but in the theory this is just a consequence of how entanglement and measurements work. No transmission required.

Indeed. I’m not completely sure what point you are trying to make, but my point is not a hidden variable point. The states can be in a perfectly correlated superposition without any hidden variables, and still not “share anything” upon collapse into an eigenstate.

I will concede that it looks a lot like one particle somehow tells the other “hey, I just collapsed into the |1> state, so now you need to as well”, but at a closer look this seems to happen on its own without any such message being shared. In particular, while the collapse of one state causes the collapse of the other, there is no physical way to distinguish between a state that was collapsed due to entanglement, and one that wasn’t. At least not until you send a sub-FTL signal to explain what happened.

So if physically, the state of particle 1 before and after particle 2 was measured is indistinguishable, how can we say that “something” was shared from particle 2 to particle 1?

I’m not sure what you mean. If something is “shared”, but this something contains no information, how can we know that it was shared? In what sense does this something even exist?

The perfect correlation of entangled particles is well established, and very cool, but perfect correlation does not require sharing of “something”. The perfect correlation is baked into the system from the start, from local interactions only.

Quantum mechanics does not allow for FTL transmission. Disallowing information flow is the same as disallowing transmission.

If you consider serious, global issues with empirical data, such as disease, poverty, hunger, the world is indeed improving, and has been for a while, see e.g. https://ourworldindata.org/grapher/share-of-population-living-in-extreme-poverty-cost-of-basic-needs

Technically ready and available now, just not ready to compete with classical computers.

Which, sadly, is a step above what fusion has achieved so far.

And Han is explicitly tortured, with Leia both tortured and enslaved. It’s pretty grim.
