@@CoolWorldsLabIn regards to FTL communication using entanglement what do you think about this idea? There is one piece of information we can send and measure on both sides accurately using entanglement, TIME. Or more specifically TIME intervals. How about we assign letters and numbers to each second that passes by between measurements? Same for punctuation marks? Use the first measurement as the signal for the person receiving the message to begin counting then count the seconds until the next measurement. We assign letters and numbers to each moment of time that passes by beforehand using that as our “key” that we give to both the sender and the receiver. So if 1 second elapses between the 1st and the 2nd measurement that equals the letter A. If 2 seconds pass by then it's the letter B. First “ping” or measurement is the starting point and the second ping is the end point. Count the time interval in between and refer to a “key” to find out what letter or number that time interval represents. We can write sentences this way. And just ignore the spins altogether. As long as both observers have the same "key", wouldn't that work? Would just need a ton of entangled particles as some have stated that once you interact with an entangled pair, that breaks the entanglement. We would basically be using 2 entangled pairs to spell out one letter. Use one entangled pair as the starting point and another entangled pair as the end point for the count. Then wait a minute between each letter we’ve sent as a reset before we send the next letter and repeat until a word is spelled out.

Thanks for this fascinating dive into neutron stars, quark stars, and strangelets! I much prefer this sort of (as you called it) "sober" take on the theory, which overcomes clickbait degeneracy pressure, to move from a metastable sensationalist state to this more informative and stable state. If you happen have a moment, I did have a couple of questions about the electrical charge of strangelets: 1. Suppose (for the sake of discussion) that a negatively-charged strangelet were here on Earth, somehow. How would it be able to overcome the negative electric charge of the electron cloud surrounding an atom of ordinary matter in order to interact with the neutrons and protons in its nucleus? 2. Suppose a negatively-charged strangelet encounters a neutron. Then (if I am understanding this correctly) one of the neutron's two down quarks will settle into a lower-energy state and become a strange quark, thus converting the neutron into more of the same strange matter that comprises the strangelet. But what happens when the negatively-charged strangelet interacts with a positively-charged proton? Is the charge of the quarks in the proton conserved? And, if not: what happens to the positive charge of the up quarks in the proton--would they eventually increase the charge of the strangelet, until it is no longer negatively charged?

~ Quarks are like the navigators of Preons. There are six Preons which correspond to each of the eternal questions: Who/What, Where/When, How/Why. Preons expand from these six questions to everything else, just like the big bang expanded to form all the energy & matter that encompasses us. The navigation of Preons corresponds with Quarks in that Quarks determine which characteristics the Preons follow. ~ Take for example, 'What', & that What is a spoon. So now the next question arises, What kind of spoon?, since the expansion of the question of a spoon requires a definite answer because there are many kinds of spoons, styles, & designs. Therefore since Quarks are also six in quantity, Charm/Up/Top & Strange/Down/Bottom, they eventually constitute neutrons, protons, & electrons, which eventually become atoms, & eventually the Periodic Table of Chemical Elements. Thus the Quarks ultimately determine what kind of spoon, whether ugly & made of something awful, or a beautiful spoon made of silver, & an ornate design/style. With the ugly spoon being directed by the Strange/Down/Bottom quarks, or the beautiful spoon being directed by the Charm/Up/Top Quarks. ~ Just remember that beauty is in the eye of the beholder, so the ugly spoon may be beautiful to someone, while the beautiful spoon may be ugly to someone else. Albeit, relevent & relative resonance & entanglement ultimately determine this outcome. ~ In conclusion, Quark Stars are the same but in a macroscopic cosmic scale.

Great video, clearly explains the science without relying too much on analogies. I’ve heard about quark stars before but hardly ever seen any good explanations- thank you. (But does quark rhyme with hark or hawk?!)

An interesting question for sure, hopefully theoretical advances in future will help shed more light on which scenarios are the most likely here.

I've only recently heard of the Quark Star. It showed up in a curiosity search for ideas related to the Hypothetical Seventh Quark. There's a growing number of Theoretical Physics folk saying things like: "a three dimensional object needs a Seventh Quark to generate a repulsive force keeping matter from collapsing altogether." Or something akin to That. I'm seriously lousy at mathematics, so, I'm unable to work on The quantum physics formulae presented by Such Folk. But, in your dazzling laymen's terminology presentation, here, I think they're on to a similar notion regarding the pressures preventing high mass neutron stars from collapsing into black holes. They're also suggesting that Gravity is An Effect, rather than a Thing and thusly, lacks Any specific Particle of Its own. That The so-called "Graviton" So widely used in science fiction stories, might NOT actually exist in Reality! It Does make sense with this Quark Star theory. Because: if you have gravitons at the pressures suggested for Quark Stars, they'd interact with Quarks striving to avoid being separated from one another! Of course, most of what I understand about This sort of thing IS mainly its use As plot devices in science fiction stories!🤪🥴 Do Gravitons, Actually, Exist? And, If So; Do they have any effects on the formation of a Quark Star? Because: the stuff I've stumbled across in this subject sounds like Gravitons would cause high mass neutron stars to Form into Black Holes instead of creating Quark Matter! And, they also suggest that everything is composed of "Quantum Fields" something akin to String Theory! 🥴 Whatever, it's a fascinating exploration, to be Sure 💖

Thank you for approaching this discussion in a factual manner and not - as you stated - sensationalising it as RU-vid does. This was very interesting, educational, and thought-provoking. Thank you. Subscribed.

LOL... "factual" manner about a purely theoretical/hypothetical unproveable "speculation"... BELIEVE THE SCIENCE... 😉... Star Trek is real... in someone's mind...

@roydoncrerar2852 5 месяцев назад

Thank you David for your insightful and indeed thoughtful content. We can always rely on Cool Worlds for, as you put it, a sober look a subject. Your lack of sensationalism is sought-after and appreciated. 🤓

"Nature's imagination far exceeds our own" is a statement that is as scary as interesting/awe inspiring. That statement deserves its own Tshirt -> just think of the conversations it would start.

Yes! I hear you man. I don’t mind being alone either. A learned state of being. I love your science content, but I will admit to losing hope for/in humanity. I got it back listening to Agro Squirrel narrates. He narrates short Sci-Fi stories that gives me hope for humanity again. Stay safe

Thank you so much for getting me thinking about this. We've popped down this intriguing cosmic rabbit hole now, let's see where it takes us. Could you please do something on JMBOs and their significance now in the scheme of things? Could they also have moons?

Personally, I really wonder what we might find in the 'dark' areas of space. The dark, frozen places you might find, and the curious things going on deep within them, at or near their cores. If only I lived in a society like in Star Trek. Exploring, up close and personal, the varying oddities of the universe would've suited me well.

Thanks for this channel! I love how astrophysical phenomena are explained. I have a question about why "our hands are not going through the table". The electromagnetism repelling force seems to be the main cause in this video, however from other sources, it seems that Pauli exclusion principle is playing the main role. Can you tell us more about that?

@LaboriousCretin 5 месяцев назад

Nice work. The only thing I would ask is could the double shock model of supernova point to a core island? Could neutron stars be considered in the island of stability, but way off from normal particles? And last the transition zones/areas/energy density regimes from neutron stars shows cutoff regimes. Why do I never see similar for Q.M. killing fields or cutoff regimes mapped into them? Or a type of island modeling inside black holes to go alongside degeneracy modeling. Keep up the good work.

@Spartacus-4297 5 месяцев назад

Prof. Kipping, your hypothesis about quark stars being an inevitable part of the evolution of neutron stars is logically sound from a material science perspective. As temperature (thermal energy) is radiated away density increases. From that, it is reasonable to conclude that as neutron stars cool and their density increases this leads to a slow progression of quark core formation as a neutron star cools. I hope you don't mind me giving my thoughts on your hypothesis Prof. Kipping, I love your content and your work, especially your work on exomoons. Please keep up the great work.

But it is not. Degeneracy pressure has to do with the physical size of quantum states, and is not sensitive to temperature. When a degenerate object cools to 0K, it’s the same size with a completely full Fermi sea.

@Spartacus-4297 5 месяцев назад

@DrDeuteron degeneracy pressure isn't affected by temperature. You are correct. However, it is affected by density, which in turn is affected by temperature. So, while temperature has no direct effect on the degeneracy pressure, the density increase as a result of the dissipation of thermal energy does have a direct effect on the degeneracy pressure. The cycle is scientifically sound, somewhat unprovable, like string theory or many worlds, but scientifically, it is sound.
