[@719Flowers]

You sound like a awesome teacher

[@Shedding]

Physicist here. Quantum entanglement would make particles change in relation to their entangled partner, but it would not yield useful information. You could see one particle with spin up and then go to the other particle and see the spin down. However, you cannot force the original particle into one state. The ramification of this is that faster than light communication would be impossible. There are things in the universe that go faster than light (like the expansion of the universe, and even entanglement) but it is information that it yields which cannot exceed light speed.

[@digitalcurrents]

Are aliens controlling the quantum states of all particles and setting them to 'read-only'? What if all particles' quantum states already have information but we can't understand it - first contact fail?

[@MB-hh6mi]

Really interesting! Any recommendations on videos or books that describe it further? I have read Chaos and Friedman’s work. I’m just an interested outsider to the field.

[@Shedding]

@@MB-hh6mi it is hard to recommend one specific book. Most of this information I obtained from my professors in undergraduate school. It was fairly common knowledge that information was the key element that could never exceed light speed.

[@DrummerRF]

To add, you also cant put information in the fact of measuring the spin state or not and therefore hide information in the action. You need the outcomes of both experiments to conclude that both changed their spin state simultaneously. (Correct me if im wrong)

[@Shedding]

@@DrummerRF right. As soon as you measure the particle. The wave equation coalesce. At this point you can understand what the particle is doing, and at the same time know what the second entangled particle is doing, but you can't inject information or force the first particle into any state. Therefore you can never send information using this method.

People of that civilization, would think their galaxy is all that there is to the universe, because they could never see anything else.

In the quiet of the night aboard the USS Enterprise, Commander Riker and Captain Picard found themselves in the captain's ready room, enjoying a rare moment of relaxation. The stars outside the window formed a mesmerizing backdrop, a reminder of the vastness of space they explored together. "Jean-Luc, do you ever tire of this endless journey?" Riker asked, his voice soft, almost reflective. Picard looked up from his book, a slight smile playing on his lips. "There are moments, Will, when the solitude of command can weigh heavily. But then, I think of the crew, of the friendships we've forged, and it all seems worthwhile." Riker nodded, understanding the sentiment all too well. "We've been through so much together. It's those bonds that keep us going, I think." The captain set his book aside and leaned back in his chair. "Indeed. It's not just the exploration of the unknown that drives us, but the connections we make along the way." There was a comfortable silence between them, one that spoke of years of mutual respect and camaraderie. Riker walked over to the replicator and ordered two glasses of Saurian brandy, handing one to Picard. "To friendship," Riker toasted, raising his glass. "To friendship," Picard echoed, clinking his glass against Riker's.

[@mbarker_lng]

What would be more mind boggling though? A universe that goes on forever or one that had a distinct "end". We would be just as mind blown contemplating questions like "Why is it the size that it is?" "Whats beyond the end?" "What is the end made of?" "What is it expanding into?". Both a finite or infinite universe are equally incomprehensible.

[@rickyspanish4792]

If I recall correctly, the conclusion that quantum entanglement can be used to do faster-than-light communication is, unfortunately, incorrect.

[@Pile_of_carbon]

Yes, you are correct. Turns out if you force an entangled particle into a certain state you break the entanglement.

[@drbuckley1]

Yeah, that's how I see it. Faster than light communication would create paradoxes where effects precede causes. Or, to put it differently, it would violate the 2nd law of thermodynamics (entropy).

[@Bosef88]

Trying to observe (which I mean the proverbial scientific quantum observance which is synonymous with direct interaction through measurement/quantification) any form of quantum entanglement, however miniscule, would inevitably skew any information one were to try to send. However, utilizing quantum entanglement via passive communication is theoretically possible. Which mainly involves identification through passive means like discrete quantitative statistical analysis in order to attempt quantum probability to convey direct information in real time is the only possible candidate. Of course, the simple premise of transmitting and receiving qubits of information, even if instantly, would be somewhat overshadowed by the factor that it will be an indeterminate process where the application of information wouldn't be a 100% action per request practical tool, like the software that networks with transmitting servers on your smart phone, for example.

[@JohnnyWednesday]

you are correct by saying the assertion is incorrect. Quantum Entanglement is indistinguishable from two basketballs that were spinning against each other in opposite directions and then separated. Knowing which way one is spinning isn't special - of course they're spinning in opposite directions, they were touching while spinning previously, like two cogs. It's not FTL - it's just being careful with the basketballs so they continue to spin in the direction they had when they were together.

[@JohnnyWednesday]

@@Bosef88 - If the equally valid Pilot Wave Theory is correct? then Quantum Entanglement doesn't exist - and since it's impossible to prove the FTL communication of entanglement? since it behaves exactly like it doesn't exist - and there's a fully valid theory that states that it doesn't exist? I think it's time to admit that the "luminiferous aether" isn't real.

I think one of the best arguments against panspermia is how quickly life started on earth after it cooled enough for it to become possible. It happened shockingly fast. The oldest stromatolites are 3.5 billion years old, and these are built by quite complex photosynthesizing cyanobacteria, found in fossils as far back as 3.8 billion years. There is no way these are the first life, as they are extremely complex, to the point of being capable of photosynthesis and complex metabolic activity. It seems that pretty much as soon as the planet was able to support life it was supporting life. Sure, it's possible that we got hit with one of those lucky life-containing meteors within a few hundred thousand years after the planet cooled off, but it seems more likely to me that life, at least on the microbial level, is just actually pretty likely so long as the proper conditions are met, and that when you have the right soup of stuff in the right conditions, it almost inevitably comes together into something that can start reproducing and evolving. We can't recreate this, of course, both because we neither know what the soup contained nor what the necessary conditions were, and because we don't have the time to wait around to see if a given combination of soup + conditions is right. A few hundred thousand years may be a flash in the pan on geological scales, but it's still longer than we can plan out an experiment for. Just the fact that life seemed to start so fast here though seems, to me, to indicate that life just sort of happens when the conditions are right for it to happen, and probably usually just dies out just as quickly because the whole universe is trying to kill us. We were lucky enough to come into being on a planet with pretty good conditions in a fairly stable region of the galaxy during a fairly stable time in the history of the universe, and if we weren't, then we wouldn't know any better because we probably would have been snuffed out as barely formed sacks of protoplasm less than a billion years after the earth got slimy. Life being common but fragile and hard to sustain seems more likely than life being so rare it only forms once and so hardy that it can travel all over the universe frozen in space rocks.

And if life did originate on earth we would have dna that spun in both directions and not just one, all life on earth the DNA helix is spun in the same direction

[@achristiananarchist2509]

@@cislife7140 That's just not true. DNA needs to spin in a single direction in order to work. It doesn't matter which one it chooses but it has to pick one or the helix structure is impossible. Same reason that we see chirality in play with regards to proteins and sugars as well. It is true that molecules of the opposite chirality would have /existed/ in the early earth, which is why we still find things like D amino acids in a few bacterial proteins today. However, natural selection would have worked very quickly to make sure that everything that had to form big, complex molecules accounted for chirality. Edit: Just for clarity, saying that life must have come from somewhere else because all DNA spins the same way is like saying that aliens must have created arctic foxes because they are all white. All DNA has to spin the same way or we wouldn't be able to reproduce or transcribe proteins. Natural selection can easily make things that, when looked at in hindsight, appear designed. DNA is always in the D configuration because all sugars, including deoxyribose, are always in the D configuration. Proteins are always in the L configuration because all amino acids are in the L configuration. L sugars and D amino acids are possible, and would have been floating around in the primordial soup, but, as complex polysaccharides and proteins wouldn't work with mixtures of components twisting every which way, natural selection did its thing and now, with a few very, very rare exceptions, these molecules are no longer found in nature.

On the faster that light communication with quantum entanglement: I've read that this is impossible. Basically you can say giggle one particle and the other jiggles the opposite way. But the person looking at the other particle doesn't know *when* to read the giggles to make sense of them. It ties in a bit to relativity (perceived time is not smooth) and I think the impossibility of knowing the one-way speed of light is a factor too. Essentially it's impossible to sync two clocks up over a large (in astronomical terms) distance without having a connection of some kind (via radio signal), which defeats the point of communicating over a distance without a connection.

[@Raging.Geekazoid]

Coherent quantum systems (entangled) aren't necessarily subject to the same restrictions as incoherent systems (normal). Recent experiments involve measuring one property of one particle and a different property of the other particle, and these are harder to explain without FTL communication within the entangled system.

This is very mundane, depending on where you are, you will find many such pieces of iron in the ground or on the surface. Where this becomes kind of mind-blowing (at least to me): That piece of iron was, at some point in an unfathomably distant past, part of a star's core for millions of years. It got hurled into space by some major event, maybe the star exploded, maybe it collapsed into a white dwarf that then collided with another white dwarf... the point is: At some point, a chunk of iron was torn from that star's core, hurled through space and after millions, if not billions of years, it hit earth, got lodged deep inside the crust and then, through unfathomably slow processes slowly re-emerged on top... where I picked it up.
