Her favorite movies are Dunkirk and Marcel the Shell with Shoes On. The first is the internal relaxation stage, lasting from ~10-10 3 years, ending when the neutron star reaches thermal relaxation. Neutron stars are made in supernova explosions which are giant neutrino factories. [6]Mass is proportional to radius cubed, and gravity is proportional to mass times inverse square of radius, so radius3 / radius2 = radius. This is a good thing to keep in mind if you buy a digital scale. Everest would no longer be in the "death zone". Toxicity aside, breathing dense air is difficult simply because it's heavy. The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. Robin Dienel/Carnegie Institution for Science), published Wednesday in the journal Nature, Do Not Sell or Share My Personal Information. Statistically, my first neutrino interaction probably happened somewhere around age 10. "In conclusion, no statistically significant present expansion rate is detected by our study within the current measurement uncertainty of 0.2 mm yr1. After 10 years, gravity would be 50% stronger. Reminds me of an XKCD joke. Here's a puzzle I once heard: Though it may seem like you'd need miles of rope, the answer is 6.28 meters. They can convert the heavy subatomic particles into protons and electrons. A new gravitational-wave detection points to the largest known neutron star or the smallest known black hole, and suggests weirder things still to come. Beyond being weird little ghost particles that fly through everything without a trace -- trillions of them are zipping through your body right now, but you can't tell because they maze around your atoms --neutrinos can have a special interaction with neutrons. For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star's core. Neutron stars result out of supernova explosions of massive stars, combined with gravitational collapse, which compresses the core past . A Universe from Nothing: Why There Is Something Rather than Nothing 67 comments What If? serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. https://www.explainxkcd.com/wiki/index.php?title=What_If_chapters&oldid=303706, Weird (and Worrying) Questions from the What If? We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Supernovae[4]"Supernovas" is also fine. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. Well, I'd argue,anything except what scientists just observed. Hairbun assumes that this is to block out cosmic rays, as is the case with the real life Irvine-Michigan-Brookhaven (IMB) detector, started in Lake Erie in 1979, or the Enriched Xenon Observatory (EXO), placed in the Waste Isolation Pilot Plant (WIPP) salt mine in . How do I move data from one tab to another in Excel? It no longer burns hydrogen, helium . Colliding neutron stars decapitate zombie theory of . Crops wouldn't stand up under their own weight. Neutron stars tend to be formed at about 1.4 solar masses, but more material can fall onto them after that. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . If the atmosphere isn't growing like the land and water are, air pressure would start dropping. 108.162.238.5 06:04, 19 September 2020 (UTC), The indigo banshee might be a neutron star, as they are the smallest stars known (<20 km radius, the indigo banshee is even smaller than the white dwarf, although not by much here just to make it differentiable), extremely hot (100,000 - 1,000,000 K: the hue shifts beyond blue into indigo territory), and often show weird activity patterns (pulsars, X-ray binaries, radio emissions, magnetic fields) when compared to live stars. Order here! Most buildings would probably be ok, although those anchored firmly into bedrock might start to behave unpredictably. [2]I'd like to remind everyone that while I write sometimes about the interesting physics of bullets, I'm not an authority on firearms safety. More details.. :) NiceGuy1 (talk) 03:54, 26 September 2021 (UTC), Let me know what you think. wouldn't work for a few reasons. Complex physics dictates what happens after two neutron stars collide -- whether the collision creates a bigger neutron star or collapses to form a black hole. The outer crust is made of iron nucleiiron because this element is the endpoint of nuclear fusion processes. What about our roads and bridges? They are responsible for, A real star type. As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. It explains that during certain supernovae, the collapse of a stellar core into a neutron star, 1057 neutrinos can be released (one for every proton in the star that collapses to become a neutron). The hardest part is sticking the landing. Is political science a good major for law? The Neutron star Interior Composition Explorer mission, or NICER, will study the extraordinary environments strong gravity, ultra-dense matter, and the most powerful magnetic fields in the universe embodied by neutron stars. "Sir, is this container under 3 ounces?" "Not sure, how much blood is there in a church mouse?" Reply . Feb. 17, 2023 10:28 a.m. PT. If you have a math background, it's sort of like seeing the expression "ln(x)e"it's not that, taken literally, it doesn't make sense, but it's hard to imagine a situation where it would apply. The cookie is used to store the user consent for the cookies in the category "Analytics". A larger planet would allow for more geologic activity, which is why some scientists think that exoplanets slightly larger than Earth ("super-Earths") could be more friendly to life than Earth-sized ones. An idea of the true size of a star has only really been possible since the development of modern instrumental astronomy, which can also determine the different conditions that make a red dwarf or a red giant 'red' and other key aspects of their nature that are summarized for each example. Planning to ride a fire pole from the moon back to Earth? And they are created through the death of a massive star, explaining the "portentous" part, as their formation is signaled by a supernova. :P 172.69.63.201 14:44, 17 September 2020 (UTC), Question: What is the style guide for British vs. American Spelling (e.g., Color vs. Colour) in explain xkcd? A real star type. xkcd.com. While you might not notice the increased gravity just yet, you'd notice the expansion. : Serious Scientific Answers to Absurd Hypothetical Questions By signing up you may also receive reader surveys and occasional special offers. This is probably a case of artistic license. Explain xkcd: It's 'cause you're dumb. Maybe its time for a brief introduction to thermodynamics. The physicist who mentioned this problem to me told me his rule of thumb for estimating supernova-related numbers: However big you think supernovae are, they're bigger than that. A giant star faces several possible fates when it dies in a supernova. "Wu, X., X. Collilieux, Z. Altamimi, B. L. A. Vermeersen, R. S. Gross, and I. Fukumori (2011), Accuracy of the International Terrestrial Reference Frame origin and Earth expansion, Geophys. The satellites would stay in roughly the same orbits, but the delicate timing that the GPS system is based on would be completely ruined within hours. What would happen if everyone jumped at the same time Xkcd? A comet crane generator could cut our energy-related greenhouse gas emissions to almost zero. A chunk of ice from space that falls to Earth gains enough energy to warm the ice up, melt it, boil it into vapor, and then heat the vapor to thousands of degrees. Of course, he was being figurativeyou wouldn't see the bullet coming, so you'd be just as likely to catch it with your face as with your glove. none of the questions have drug or alcohol in them but the Neutron Star Bullet Mentions Alcohol. This heat energy would be about 100 times greater than the energy needed to bring even a very cold comet up to room temperature, so a comet falling from space would heat the Earth 100 times more than it cooled it. Anybody know why? This website uses cookies to improve your experience while you navigate through the website. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Suns mass. Previously, she was a science reporter with a start-up publication called The Academic Times, and before that, was an immunology researcher at Weill Cornell Medical Center in New York. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! All rights reserved. The nuclei get pressed close together so . Gravity varies by this much between different cities already. For the rest of the day, you wouldn't notice much of anything. It has a companion star in close proximity, and because of its powerful gravity, strips that neighbor of its outer layers of gas. Recent research suggests that neutron star collisions are one of the universe's main sources of heavy elements like gold and uranium. [4]Floor water. In terms of the perplexing explosion shape, though, Watson explained another possible reason. There are no purely vertical cliffs that are that tall, so you'd need to fire the bullet at an angle, and it would have significant sideways speed at the top of its arc. xkcd.com; what if? Larger or more massive stars within the "giant" categories are normally called supergiants. Which would still be less than 1% of the ants in the world. The cookie is used to store the user consent for the cookies in the category "Other. 08.23.07. Karam calculates that the neutrino radiation dose at a distance of one parsec[6]3.262 light-years, or a little less than the distance from here to Alpha Centauri. However, were not just worried about the mass in the spoon. What If? A neutron star is the remnant of a massive star (bigger than 10 Suns) that has run out of fuel, collapsed, exploded, and collapsed some more. and How To provides his best answers yet to the weirdest questions you never thought to ask. (Assuming the average composition of rock were maintained.). She graduated from New York University in 2018 with a B.A. No. After a month, the Earth would have expanded by 26 kilometersan increase of 0.4%and its mass would have increased by 1.2%. people had noticed that the continents fit together. If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. On average, out of that massive flood, only one neutrino will "hit" an atom in your body every few years. But opting out of some of these cookies may affect your browsing experience. Use the fact that a Neutron Star has about 1.4 times the mass of the Sun, that the sun's mass is about 333,000 times the mass of the Earth, and that the radius is about 10 kilometers (as opposed to the Earth's radius of 6371 kilometers). [8]See What-If #64. How do I get rid of whiteheads on my nose naturally? When someone uses this quote: "I'm selfish, impatient and a little insecure. [1]Yes, I have a citation for this. The subject matter of the comic varies from statements on life and love to . The neutron stars we can observe average about 1.8 million degrees Fahrenheit, compared to about 9,900 degrees Fahrenheit for the Sun. A neutron star isn't as dense as a black hole . After years had passed, the top of Mt. A real thing, though not a true star, but a remnant of one. A spherical explosion [provides] much greater precision in the measurement.". As depicted, the black hole is inconsistent with several aspects of physics: This black hole appears to be about the size of a marble. "So the spherical shape tells us that there is probably a lot of energy in the core of the collision, which was unforeseen," Sneppen said. A spoonful of neutron star suddenly appearing on Earths surface would cause a giant explosion, and it would probably vaporize a good chunk of our planet with it. But what if we took just a spoonful of it and transported it to Earth? How do I minimise waste on a flight? If a bullet with the density of a neutron star were fired from a . All Rights Reserved 2022 Theme: Promos by. Inbox, #3, Weird (and Worrying) Questions from the What If? Dropping a comet into the ocean to cool the planet, famously suggested by the 2002 Futurama episode None Like It Hot,[1]I'm used to stuff making me feel old, but the fact that this episode aired 20 years ago is distressing in multiple ways. Spice up your small talk with the latest tech news, products and reviews. Water that goes over Niagara Falls, for example, gains enough kinetic energy during the 50-meter plunge to warm it up by about 0.1C by the time it reaches the bottom. Explanation []. Munroe states on the comic's website that the name of the comic is not an initialism but "just a word with no phonetic pronunciation".. 3.262 light-years, or a little less than the distance from here to Alpha Centauri. Argis13 (talk) 14:18, 25 February 2021 (UTC). It wouldn't just cancel out the cooling effect of the iceover time, the comet's greenhouse effect would deliver as much heat as if you'd just let it slam into the planet and vaporize. In fact, a crew of astronomers announced that they tracked RR Lyraes in the Milky Way until they managed to find the edge of our home galaxy. She covers climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical thought experiments. This is the type of star that. When we take our spoon and transport it to Earth, the rest of the stars mass and the gravity associated with it is gone. Inbox, #5, Weird (and Worrying) Questions from the What If? [9]Although I wouldn't trust the elevators. Surface gravity would only have gone up by 0.4%, rather than 1.2%, since surface gravity is proportional to radius. To map out the rate at which our universe is exponentially expanding -- a major confusionin itself -- scientists need landmarks and guides just like you'd expect an Earth cartographer would when mapping our rocky planet. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. "@xkcd Reminds me of the Neutron Star cocktail from "What If?"" Neutron stars are phenomenally dense. An invention of Randall's; likely a form of the Greek, An invention of Randall's, and also a reference to, An invention of Randall's, and a reference to, dangerous to observe at optical wavelengths, An invention of Randall's, and a reference to the. book series or on the blog. While a normal black hole has the mass of 9.945e+30 (five times the sun. Similarly, it's so hard to get enough neutrinos to compel even a single one of them to interact with matter, making it hard to picture a scenario in which there'd be enough of them to affect you. This page was last edited on 26 May 2022, at 19:45. Rocket Golf February 25, 2014. Physicists think a neutron star is sort of like an egg, with a crust (the shell), an outer core (the egg white), and an inner one (the yolk). The story icomes from a National Geographic video. Breathing would be difficult. Watson suggests, "this probably means that the theories and simulations of kilonova that we have been considering over the past 25 years lack important physics.". It would just take a lot of patience. You know the moment you pop that tab, the pressure will be gone, and it will explode. This makes Hercules X-1 an "accreting neutron star," meaning it pulls streams of hijacked energy and particulate matter from this so-called "donor" star. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. At this point, even the strongest humans would only be able to walk with great difficulty. feed 2022 . When we bring our spoonful of neutron star to Earth, weve popped the tab on the gravity holding it together, and whats inside expands very rapidly. That was unexpected. After a month, you'd see a lot of cracks opening up in long concrete structures and the failure of elevated roads and old bridges. Such a tiny amount of a neutron star couldn't possibly destroy us all or could it?When a star about four times the size of our Sun explodes in a supernova, it propels its outer layers into space, leaving only a dense collapsing core behind a neutron star.Transcript and sources: https://insh.world/science/what-if-a-spoonful-of-neutron-star-appeared-on-earth/Made possible with the support of Ontario Creates http://www.ontariocreates.caWatch more what-if scenarios: Planet Earth: https://www.youtube.com/watch?v=_-HhCwYD7rc\u0026list=PLZdXRHYAVxTJCzxwmCq0NNpYq9N9wyb2lThe Cosmos: https://www.youtube.com/watch?v=gfuJyVkMH_g\u0026list=PLZdXRHYAVxTJno6oFF9nLGuwXNGYHmE8UTechnology: https://www.youtube.com/watch?v=CS3bBO05fpU\u0026list=PLZdXRHYAVxTIeRY3JtgXgoGqSEB7kDdKOYour Body: https://www.youtube.com/watch?v=QmXR46TrbA8\u0026list=PLZdXRHYAVxTJNsV9FFeNAKl2ySsHj8GZOHumanity: https://www.youtube.com/watch?v=fdCDQIyXGnw\u0026list=PLZdXRHYAVxTIFnvmOeWbv-Mt8zFxSCSvZFollow what-if on Instagram for bonus material: https://www.instagram.com/what.if.show/Suggest an episode: http://bit.ly/suggest-whatifT-shirts and merch: http://bit.ly/whatifshopFacebook Watch: https://www.facebook.com/What.If.scienceWatch on Tubi: http://bit.ly/what-if-tubi\"Imagination will often carry us to worlds that never were. The only thing keeping the neutrons from collapsing further is neutron degeneracy pressure, which prevents two neutrons from being in the same place at the same time. Want to know what would happen if you rode a helicopter blade, built a billion-story building, made a lava lamp out of lava, or jumped on a geyser as it erupted? This Neutron Star Explosion Was Perfect. Neutron stars are formed when a massive star runs out of fuel and collapses. So, perhaps the neutron stars' neutrons got converted? \[ 0.5\text{ nanosieverts} \times\left ( \frac{1\text{ parsec}}{x}\right )^2 = 5\text{ sieverts} \] The phrase "lethal dose of neutrino radiation" is a weird one. more from Astronomy's weekly email newsletter. Generally, it turns into heat. [citation needed], I'm thinking a table (Name, appearance, summary, is real?, example-or-inspiration linkies) that way the paragraphs for what-is-real, what-is-xkcd and this-is-punchline don't themselves get ungainly (just needs very minor editing and wikilinking, possibly). GPS timing is incredibly precise; of all the problems in engineering, it's one of the only ones in which engineers have been forced to include both special and general relativity in their calculations. \[ x=0.00001118\text{ parsecs}=2.3\text{ AU} \] If you want to use larger bullets, you'll need a much larger drop; an AK-47's bullet can go over two kilometers upward. There's been a lot of them, and they seem repetitive - no real new humor. These cookies will be stored in your browser only with your consent. If your scale has a precision of more than two decimal places, you need to calibrate it with a test weightthe force of gravity at the scale factory isn't necessarily the same as the force of gravity at your house. When would the Earth eventually become a black hole? Join Us in Tucson for Our Annual Public Star Party! This crowd takes up an area the size of Rhode Island. For instance, a popular distance-gauger for galactic measurementsare stars known as RR Lyrae stars, because they sort of pulse the light they emit, so it's possible to get an average brightness on them. No observers of any of these celestial bodies have been petrified. A real star type. This means you're free to copy and share these comics (but not to sell them). Even after a day, the extra 5.4 kilometers would be handled easily by virtually all structures. To avoid the problem of rifts in the ground, let's imagine all the matter in the Earth, from the crust to the core, starts expanding uniformly. How long would it take for people to notice their weight gain if the mean radius of the world expanded by 1cm every second? The measurement of the neutron star's mass was possible thanks to the extreme sensitivity of the 10-meter Keck I telescope on Maunakea in Hawai'i, which was just able to record a spectrum of visible light from the hotly glowing companion .
