It's like the idiom "knock me over with a feather" or the phrase "football stadium filled to the brim with ants". Neutron star matter is completely optically thick to photons. In fact, it's honestly sort of impressive to find a solution that would actively make the problem worse in so many different ways. 125. Inbox, #11, Weird (and Worrying) Questions from the What If? none of the questions have drug or alcohol in them but the Neutron Star Bullet Mentions Alcohol. View our Privacy Policy. Therefore, only the surfaces can cool by the emission of such radiation. According to ballistics lab Close Focus Research, this is almost exactly how high a .22 Long Rifle bullet will fly if fired directly upward. All rights reserved. This page was last edited on 26 May 2022, at 19:45. When our sun enters this phase in a few billion years, it will consume Mercury, Venus, and possibly the Earth. and How To provides his best answers yet to the weirdest questions you never thought to ask. Tungsten Countertop . astronomy. White dwarf: 0.003-0.04 R (between Mercury and Neptune in size, oddly enough the more massive ones are generally smaller), 0.07-1.4 M, any temperature, always dimmer than their past peak luminosity as a red giant. Most buildings would probably be ok, although those anchored firmly into bedrock might start to behave unpredictably. Outside of low-pressure domes, the air would become unbreathable for a different reason. But what if we took just a spoonful of it and transpo. When she's not at her desk, she's trying (and failing) to raise her online chess rating. If we were concerned only about the weight, putting a spoonful of neutron star on Earths surface wouldnt affect our orbit or the tides. The title text is in the style of a Wikipedia page's hatnote / reference note. A spherical explosion [provides] much greater precision in the measurement.". Want CNET to notify you of price drops and the latest stories? more from Astronomy's weekly email newsletter. How do I minimise waste on a flight? [4]As it turns out, the ocean is expanding, since it's getting warmer. A tablespoon of neutron star weighs more than 1 billion tons (900 billion kg) the weight of Mount Everest. 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. I was raised Quaker; I've never held a gun, much less fired one. 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). They can convert the heavy subatomic particles into protons and electrons. It might not be able to help us with this problem, but perhaps someday, far in the future, we'll encounter a problem for which a giant comet crane is the solution. What is the process that creates a neutron star? So, perhaps the neutron stars' neutrons got converted? As the Earth started expanding, you'd feel a slight jolt, and might even lose your balance for a moment. Before publishing the first what if? Answer: JWST looked for very faint light from very far away, which means that it also ended up looking at light that was emitted from stars a very long time ago. If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. Which would still be less than 1% of the ants in the world. The second is this neutrino cooling stage, lasting to ~10 5 years. Neutron stars are the densest things besides black holes. Time is the only remedy for such puzzling cosmic mysteries. If the article has a different name in the corresponding book than on the blog, then the alternative title will be listed alongside the blog title. Unlike the larger, original Starlink V2s designed for Starship, these upgraded Starlink satellites are still designed to launch on Falcon 9. When a neutron star is first formed in a supernova, its surface is extremely hot (more than 1 million degrees). The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. If you weighed 70 kg when the expansion started, you'd weigh 88 kg now. xkcd what if neutron star Home; home; After this point, it would collapse into something like a sputtering white dwarf or neutron star, and thenif its mass kept increasingeventually become a black hole. In the scenario where the atmosphere isn't expanding, the air would become thin enough to be difficult to breathe even at sea level. At this point, the star is simply getting . The #1 New York Timesbestselling author of What If? 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. DeathNoteRs 7 yr. ago. [2]Which would still be less than 1% of the ants in the world. It's okay. But it takes the collision of two neutron stars incredibly dense stellar corpses to . Argis13 (talk) 14:18, 25 February 2021 (UTC). (, An invention of Randall's, and a reference to the elves of. 172.68.24.118 13:53, 18 September 2020 (UTC), Um, I didnt have to solve a catchpa to edit. ''Your stupid!''. Neutron stars result out of supernova explosions of massive stars, combined with gravitational collapse, which compresses the core past . The life of super-Earths: how the hunt for alien worlds and artificial cells will revolutionize life on our planet. After this point, it would collapse into something like a sputtering white dwarf or neutron star, and thenif its mass kept increasingeventually become a black hole. It does not store any personal data. [Editor's note: This article was updated Feb. 23, 2022.]. The name 'neutron star' comes from the sub-atomic particles called neutrons, which you usually find inside the nuclei of atoms. The cookie is used to store the user consent for the cookies in the category "Performance". The pressure inside planets is roughly proportional to the square of their surface area, so the Earth's core would be squeezed tightly. When the core of a massive star undergoes gravitational collapse at the end of its life, protons and electrons are literally scrunched together, leaving behind one of nature's most wondrous creations: a neutron star. No. At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up . Remember that hypothetical crane that lets you lower comets to the surface? -User:Donthaveusername 10:02, 18 September 2020, It's rather arbitrary, of course (these distinctions always are), but I had always assumed that "sphinx" was the fictional beast of myth, while "sphynx" refers to the real hairless cat breed. 2 is sure to be another instant classic adored by inquisitive readers of all ages. In short, the answer to Grey's question is yes 500 mph winds would send you flying through the air. . 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. The comet isn't the important part, the crane is. You get the point. book, articles were posted weekly.. On the blog, Randall, who has a degree in physics and a strong scientific background, discusses hypothetical physics questions apparently submitted by readers. If you observed a supernova from 1 AU awayand you somehow avoided being being incinerated, vaporized, and converted to some type of exotic plasmaeven the flood of ghostly neutrinos would be dense enough to kill you. His 2014 book What If? [1]Yes, I have a citation for this. 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. Order here! In addition to dust and water, they contain a small amount of CO2, which would be released into the atmosphere as the comet melted. As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. The pantheon of stars illustrated extend the use of 'dwarf' and 'giant' as if describing mythical or fictional beings, drawing upon others from the fantasy ilk with hues and shades that may not be typically described, or even encountered, by astronomers. Only their immense gravity keeps the matter inside from exploding; if you brought a spoonful of neutron star to Earth, the lack of gravity would cause it to expand rapidly. After 40 years, Earth's surface gravity would have tripled. "@xkcd Reminds me of the Neutron Star cocktail from "What If?"" This cookie is set by GDPR Cookie Consent plugin. [3]If you want to be mean to first-year calculus students, you can ask them to take the derivative of ln(x)e dx. This Neutron Star Explosion Was Perfect. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Suns mass. The hardest part is sticking the landing. A tiny piece of a comet would float for a short time until it became waterlogged, melted, and broke apart. xkcd.com. comics from xkcd. Perhaps humans could survive in specially-built controlled-pressure domes, moving around by keeping most of our bodies submerged in water. The dynamics of really huge rocky planets aren't often analyzed, since there's no obvious way that they could form; anything that large will have enough gravity to gather hydrogen and helium during planet formation and become a gas giant. 2.3 AU is a little more than the distance between the Sun and Mars. The neutron stars we can observe average about 1.8 million degrees Fahrenheit, compared to about 9,900 degrees Fahrenheit for the Sun. Although there are some black holes with a mass of 70 times the sun). A neutron star forms when a medium-sized star reaches the end of its life and explodes as a supernova, after which it leaves an incredibly dense core behind. 2023 CNET, a Red Ventures company. Inbox, #5, Weird (and Worrying) Questions from the What If? would change Earth's radiation balance, trapping heat near the surface and raising the planet's temperature. Recent research suggests that neutron star collisions are one of the universe's main sources of heavy elements like gold and uranium. [5]Although letting a comet slowly decay on the surface would definitely be preferable to a high-speed impact, as any dinosaur from the end of the Cretaceous can tell you. 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 you were hanging out in a hot-air balloon directly above the firing range it's possible that you could reach out and snag the bullet at the apex of its flight. Red dwarf: 0.09-0.5 R; 0.07-0.3 M, 1500-4000 K, 0.00001-0.05 L. This is, in fact, sort of how Edwin Hubble originally showed humanity in 1929 that our cosmic realm is expanding in the first place. If it comes down to a vote, I think that we should stick with American spelling in general, because Randall is American. Unfazed by absurdity, Randall consults the latest research on everything from swing-set physics to airplane-catapult design to clearly and concisely answer his readers questions. 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. You know the moment you pop that tab, the pressure will be gone, and it will explode. A bigger projectile can go further. The largest class of star in the main sequence, these are highly luminous and have life spans measured in only millions of years, rather than the billions or trillions of years for other star types. This cookie is set by GDPR Cookie Consent plugin. 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. You might notice the difference in weight on a scale, but it's not a big deal. Some types of stars can vary in a wide range of sizes as well. Stretching a 40,000-kilometer line an extra 6.28 meters is pretty negligible. Is political science a good major for law? Colliding neutron stars decapitate zombie theory of . The neutron star, known as PSR J0952-0607, was discovered in 2017 about . This effect can be seen, dramatically, when a bullet is fired at ice. While a normal black hole has the mass of 9.945e+30 (five times the sun. The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. This an illusion, of course; it's not possible to catch a bullet like that. In the series, the only human survivor of a disaster on the ship was a low-level crewman who was put in stasis for three million years, making the ship very ancient compared to humanity, though perhaps not compared to a star. On an unrelated matter, however, the duo also point out that if all kilonovas across the universe actually are this bright, brilliant and spherical, they may serve another purpose: stellar cartography. They are extremely dense and no longer undergo nuclear fusion. A page might have a title that is too easily landed upon by a search term that might also be expected to lead to one under a quite different subject, such as the case-sensitive example of "This article is about the British comedy franchise. 08.23.07. If a bullet with the density of a neutron star were fired from a . It no longer burns hydrogen, helium . After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. Neutron stars are made in supernova explosions which are giant neutrino factories. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language". It would instantly expand to about 5 miles in diameter. Thus, no matter your gun, youre not shooting a bullet around the Earth. Monisha Ravisetti. Lett., 38, L13304, doi:10.1029/2011GL047450. Neutron stars pack their mass inside a 20-kilometer (12.4 miles) diameter. And indeed, it is by nine orders of magnitude. Her favorite movies are Dunkirk and Marcel the Shell with Shoes On. Supernovae[4]"Supernovas" is also fine. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. To detect neutrinos, people build giant tanks filled with hundreds of tons of material in the hopes that they'll register the impact of a single solar neutrino. Inbox, #7, Weird (and Worrying) Questions from the What If? [6]Mass is proportional to radius cubed, and gravity is proportional to mass times inverse square of radius, so radius3 / radius2 = radius. However, a suitably tough baseball glove might be able to snag it. This would be similar to the situation on Earth billions of years ago, when we had more radioactive material and thus a hotter mantle. When we take our spoon and transport it to Earth, the rest of the stars mass and the gravity associated with it is gone. Monisha Ravisetti is a science writer at CNET. A neutron star isn't as dense as a black hole . The star starts fusing helium to carbon, like lower-mass stars. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. Explain xkcd: It's 'cause you're dumb. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. book series or on the blog. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. "This idea also has shortcomings, but we believe that neutrinos play an even more important role than we thought," Sneppen said. After 10 years, gravity would be 50% stronger. 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. 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. Applying the physicist rule of thumb suggests that the supernova is brighter. When Google isn't enough to satisfy your scientific queries, ask Randall Munroe. Not only would the ground (and atmosphere) be rising toward them, but the increased gravity would also cause their orbit to slowly shrink. What about our roads and bridges? These stellar beasts, made mostly of neutrons, are basically ultra-dense cosmic corpses roaming around space and, with incomprehensibly strong gravitational fields, torturing everything in their paths. What If? xkcd.com. "Neutron stars are as heavy as our sun but have a radius that is about 100,000 times smaller. A fatal radiation dose is about 4 sieverts. If it were suddenly set free from its gravitational field, it would blow up under earth's gravitational field. Red giant: 3-2000 R; 0.3-50 M, 2500-4000 K, 0.3-650000 L. [1]This was confirmed by Mythbusters in episode 4 of Season 4. Order here! Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. Well, I'd argue,anything except what scientists just observed. 0:52. After the first day, the Earth would have expanded by 864 meters. 162.158.103.125 11:30, 17 September 2020 (UTC), Teal Sphinx? Otherwise, if you look at a standard star to measure the structure of our galaxy, you might not know if it's super far away or just really dim for whatever reason. After years had passed, the top of Mt. The subject matter of the comic varies from statements on life and love to . It would have lost its upward momentum, but not its rotational momentum; it would still have the spin given to it by the barrel of the gun. At somewhere around 6 atmospheres, even ordinary air becomes toxic.[13]R.M. After five years, gravity would be 25% stronger. Once its nuclear fuel is consumed, the . Most other clocks would keep working fine. [9]Although I wouldn't trust the elevators. More massive stars explode as supernovas, while their cores collapse into neutron stars: ultra-dense, fast-spinning spheres made of the same ingredients as the nucleus of an atom. 2 is sure to be another instant classic adored by inquisitive readers of all ages. Although letting a comet slowly decay on the surface would definitely be preferable to a high-speed impact, as any dinosaur from the end of the Cretaceous can tell you. How long should I wait to text after being left on read? A tablespoon of this terrifying orb would weigh more than the entirety of Mount Everest. 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. feed 2022 .

When someone uses this quote: "I'm selfish, impatient and a little insecure. 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".. "In conclusion, no statistically significant present expansion rate is detected by our study within the current measurement uncertainty of 0.2 mm yr1. They're like the baby brothers of black holes. One is that dropping things from space creates heat. Lightcaller (talk) 01:55, 17 September 2020 (UTC), Wat. Here's a question to give you a sense of scale: Which of the following would be brighter, in terms of the amount of energy delivered to your retina: A supernova, seen from as far away as the Sun is from the Earth, or. 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. Neutron stars tend to be formed at about 1.4 solar masses, but more material can fall onto them after that. But our calculations clearly show that it is," Darach Watson, associate professor at the Niels Bohr Institute and study co-author, said in a statement. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. On average, out of that massive flood, only one neutrino will "hit" an atom in your body every few years. Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions, 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. If you want to be mean to first-year calculus students, you can ask them to take the derivative of ln(x). Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. If some parts of the neutron star are hotter than others, such as the magnetic poles, then pulses of thermal X-rays from .
