For the type of star, see Red dwarf." As gravity increases, then air gets heavier. 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. Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. Sure, it would release a little CO2, but it would be nothing compared to the pollution from our current sources of energy. That star can either be completely destroyed, become a black hole, or become a neutron star.The outcome depends on the dying star's mass and other factors, all of which shape what happens when stars explode in a supernova.. Neutron stars are among the densest objects in the cosmos. As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. 718-719 of the IPCC WG1 AR5 report for more. book series or on the blog. For most of them, the limiting factor isn't weight, but wind. That's why this is a neat question; supernovae are unimaginably huge and neutrinos are unimaginably insubstantial. (Heavier stars produce stellar-mass black holes.) Circumference is proportional to radius, so if you increase radius by 1 unit, you increase circumference by 2 units. 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. shooter is at sea level and catcher is up a mountain at the extreme range of the gun. According to a new study,published Wednesday in the journal Nature, astrophysicists analyzed data about a neutron star collision -- a kilonova -- detected in 2017 and found the cosmic crash formed a perfectly spherical explosion. Eventually, they would have to break up, right? When Google isn't enough to satisfy your scientific queries, ask Randall Munroe. [14]Plummer, H. C., Note on the motion about an attracting centre of slowly increasing mass, Monthly Notices of the Royal Astronomical Society, Vol. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . [5]Lawrence Grybosky, Thermal Expansion and Contraction. Paint the Earth February 18, 2014. Most of the Earth's heat is provided by radioactive decay of minerals in the crust and mantle,[12]Although some radioactive elements, like uranium, are heavy, they get squeezed out of the lower layers because their atoms don't mesh well with the rock lattices at those depths. The mass of the sun is 1.989 10 30 kg while the mass of the moon is 7,348 * 10 22 kg. [1]Yes, I have a citation for this. This is due to a combination of factors. feed 2022 . although it still periodically makes the rounds on YouTube. The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language". Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Sun's mass. More active plate tectonics might be good for life. Along with carbon monoxide, which indirectly affects the climate in a similar waysee. Inbox, #6, Weird (and Worrying) Questions from the What If? https://www.explainxkcd.com/wiki/index.php?title=What_If_chapters&oldid=303706, Weird (and Worrying) Questions from the What If? Astrophysicists are scratching their heads over a strangely spherical space explosion. Plate tectonics play a key role in stabilizing the Earth's climate, and planets smaller than Earth (like Mars) don't have enough internal heat to sustain long-term geologic activity. [1]Less often if you're a child, since you have fewer atoms to be hit. On the other hand, since you'd be heavierand the mountain would be tallerclimbing would be more work. Res. 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. Far-Traveling Objects March 4, 2014. xkcd.com; what if? [1] People have long suggested that it might be. Before you go on a cosmic road trip, feed the residents of New York City to a T. rex, or fill every church with bananas, be sure to consult this practical guide for impractical ideas. The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. It would instantly expand to about 5 miles in diameter. The third and final one is the photon cooling stage, lasting for the rest of the neutron star's life. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . Inbox, #11, Weird (and Worrying) Questions from the What If? Inbox, #8, Weird (and Worrying) Questions from the What If? Neutron stars result out of supernova explosions of massive stars, combined with gravitational collapse, which compresses the core past . Most other clocks would keep working fine. The phrase "lethal dose of neutrino radiation" is a weird one. Spice up your small talk with the latest tech news, products and reviews. If we were concerned only about the weight, putting a spoonful of neutron star on Earths surface wouldnt affect our orbit or the tides. 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. The most common, smallest, and coolest type of true star in the universe. How long would it take for people to notice their weight gain if the mean radius of the world expanded by 1cm every second? "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. Ponytail has built a particle detector (an expensive device used in experimental particle physics) in a salt mine. Typical properties are shown below. Star Sand February 11, 2014. Death from Above. You'd probably notice the weight gain, and you'd definitely notice the failure of roads, bridges, power lines, satellites, and undersea cables. [1] But under the right conditions, you could catch a bullet. The cause of the collapse would be the expanding ground below them, not the increased gravity. Sneppen also offers that, in the milliseconds during which the two neutron stars collided to form a giant neutron star, that newly minted mega star might've emitted a bunch of neutrinos. and gently set the comet in the ocean. How long should I wait to text after being left on read? 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.". The millions of people around the world who read and loved What If? People have long suggested that it might be. Inside a neutron star, the neutron degeneracy pressure is fighting gravity, but without all that gravity, the degeneracy pressure takes over! It's a shame humans wouldn't live this long, because at this point, something really neat would happen. 16. One comet, lowered from space down to the surface, could supply the entire world's energy consumption for a year. [6]Mass is proportional to radius cubed, and gravity is proportional to mass times inverse square of radius, so radius3 / radius2 = radius. Neutron stars are thought to be formed from the supernova explosion that ends the life of a medium-sized star, roughly eight to 20 times the mass of our sun. Generally, it turns into heat. This an illusion, of course; it's not possible to catch a bullet like that. Her favorite movies are Dunkirk and Marcel the Shell with Shoes On. If it's going fast enough, a feather can absolutely knock you over. 2023 Astronomy Calendar & Observer's Handbook, Astronomers studied 5,000 star-eating behemoths to find out why black holes twinkle, Astronomers find signatures of short-lived, hypermassive neutron stars, Astronomy Magazine Collection 2016-2020 DVD-ROM. Can I leave an internship for another internship? : Serious Scientific Answers to Absurd Hypothetical Questions This is a list of What If? That was unexpected. The #1 New York Timesbestselling author of What If? And by that point, you may find you've attracted some attention. I had to turn it over in my head a few times after I heard it. It's like the idiom "knock me over with a feather" or the phrase "football stadium filled to the brim with ants". In short, the answer to Grey's question is yes 500 mph winds would send you flying through the air. (This added heat is minor compared to the cooling effects of evaporation on the way down, so the actual temperature at the bottom is likely colder.). If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. As such, they are the densest objects in the universe. It explains that during certain supernovae, the collapse of a stellar core into a neutron star, 10 57 neutrinos can be released (one for every proton in the star that collapses to become a neutron). [8]See What-If #64. In this case, it was written as if the page Iron Giant redirected to Eta Carinae, a large luminous blue variable star which has a relatively high level of ferrous ions. and How To provides his best answers yet to the weirdest questions you never thought to ask. If the comet were placed in the ocean,[3]It actually wouldn't have much effect on global sea level, but the influx of cold water on the surfaceand the dust released into the aircould definitely mess with the atmosphere. The reason you don't notice the neutrino flood is that neutrinos hardly interact with ordinary matter at all. Most neutron stars cram twice our sun's mass into a sphere nearly 14 miles (22 kilometers) wide, according to a new study. "In conclusion, no statistically significant present expansion rate is detected by our study within the current measurement uncertainty of 0.2 mm yr1. This 'infographic' chart purports to be a comparative guide to various star types, often described by a basic color, which is something that even naked-eye astronomy has determined, and may be qualified as 'dwarf' or 'giant' to describe relative sizes. There's been a lot of them, and they seem repetitive - no real new humor. Not only would the ground (and atmosphere) be rising toward them, but the increased gravity would also cause their orbit to slowly shrink. and more Earth means more heat. These cookies track visitors across websites and collect information to provide customized ads. In true xkcd tradition, this is taken beyond reality. 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. What about our roads and bridges? At this point, even the strongest humans would only be able to walk with great difficulty. The neutron star, a pulsar designated PSR J0952-0607, is thus the densest object within sight of Earth. 1572948 (talk) 06:31, 25 July 2021 (UTC), https://en.wikipedia.org/wiki/Cosmic_latte, https://www.zdnet.com/article/20-years-of-linux-on-big-iron/, https://www.explainxkcd.com/wiki/index.php?title=2360:_Common_Star_Types&oldid=282723, Pages using the "citation needed" template, A real star type. This is a good thing to keep in mind if you buy a digital scale. 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. "Supernovas" is also fine. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! The nuclei get pressed close together so . Outer space is a lot higher up than Niagara Falls,[citation needed] so the plunge down into the atmosphere at the bottom of Earth's gravity well adds a lot more than 0.1 degrees worth of heat. This means that when a particle accelerator (which produces neutrinos) wants to send a neutrino beam to a detector somewhere else in the world, all it has to do is point the beam at the detectoreven if it's on the other side of the Earth! Inbox, #7, Weird (and Worrying) Questions from the What If? It looks like it should be "1" or something, but it's not. A tablespoon of a neutron star weights about 1 billion tons. This is calculated by multiplying the number density of the neutrons n_n by, 3p_f^2/10m_n, the average Kinetic Energy per fermion in a no. What If chapters. X-ray: NASA/CXC/UNAM/Ioffe/D.Page, P. Shternin et al; Optical: NASA/STScI; Illustration: NASA/CXC/M. As the Earth grows, the Moon would, like all our satellites, gradually spiral inward. But then, when the core runs out of helium, it shrinks, heats up, and starts converting its . A tablespoon of a neutron star weights about 1 billion tons. When it comes to shape, though, neutron star collisions seem to be key. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. A stone si. 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 . It no longer burns hydrogen, helium . View our Privacy Policy. A real thing, though not a true star, but a remnant of one. Monisha Ravisetti is a science writer at CNET. For the rest of the day, you wouldn't notice much of anything. 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. After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. Remember that hypothetical crane that lets you lower comets to the surface? 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. It would instantly expand to about 5 miles in diameter. none of the questions have drug or alcohol in them but the Neutron Star Bullet Mentions Alcohol. Less often if you're a child, since you have fewer atoms to be hit. Therefore, only the surfaces can cool by the emission of such radiation. "Supernovii" is discouraged. Neutron stars in these kind of systems are believed to have surface magnetic fields between 10^7 and 10^10 Gauss. In fact, neutrinos are so shadowy that the entire Earth is transparent to them; nearly all of the Sun's neutrino flood goes straight through it unaffected. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. The release of magnetic energy could cause the matter in the explosion to be distributed more spherically. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. 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. Using the inverse-square law, we can calculate the radiation dose: When big stars (at least 20 times the size of our sun) die, they become black holes, but when smaller stars (between about eight and 20 times the size of our sun) die, they turn into neutron stars. I was raised, Don't do this. 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 . [5]Karam, P. Andrew. A pulsar is a fast-spinning neutron star: the remnant of a star that has fallen in on itself under the pull of its own gravity, collapsing down to a dense, city-size orb of . Breathing in this situation would be difficult. No observers of any of these celestial bodies have been petrified. This note was added to Wikipedia, but quickly removed. 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. "Gamma And Neutrino Radiation Dose From Gamma Ray Bursts And Nearby Supernovae." No. Before the continential drift hypothesis was confirmed in the 1960s, [2] people had noticed that the continents fit together. 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. This is probably a case of artistic license. The mass sun is 400 times heavier than the mass of the moon. "Supernovii" is discouraged. This effect can be seen, dramatically, when a bullet is fired at ice. Join Us in Tucson for Our Annual Public Star Party! At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up . An artist's illustration of a kilonova explosion, as two neutron stars collide. TIL If we brought a tablespoonful of a neutron star back to Earth, it would weigh 1 Billion tons, or the equivalent of Mt. Dig down, and the pressure increases relentlessly. 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. This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. "Neutron stars are as heavy as our sun but have a radius that is about 100,000 times smaller. Applying the physicist rule of thumb suggests that the supernova is brighter. 2 What would happen if a neutron star was placed close to the earth? I've seen quite a bit of that on this page. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. xkcd.com. One is that dropping things from space creates heat. We also use third-party cookies that help us analyze and understand how you use this website. After the first day, the Earth would have expanded by 864 meters. What is the process that creates a neutron star? At somewhere around 6 atmospheres, even ordinary air becomes toxic.[13]R.M. 08.23.07. 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. [11]Sasselov, Dimitar D.. At least I think. Inbox, #12, Lose Weight the Slow and Incredibly Difficult Way. The neutron star, known as PSR J0952-0607, was discovered in 2017 about . 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. Where are the best places to see the 2023 and 2024 solar eclipses? All Rights Reserved 2022 Theme: Promos by. This page was last edited on 30 December 2022, at 22:23. 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. After 40 years, Earth's surface gravity would have tripled. Tungsten Countertop . Various ideas were put forward to explain this, including the idea that the ocean basins were rifts that opened in the surface of a previously-smooth Earth as it expanded. Small chunks of ice falling from space disintegrate and boil away before they reach the ground, warming the upper atmosphere. How close would you have to be to a supernova to get a lethal dose of neutrino radiation? Franz and P.C. The series is produced by Marvel Studios and was released on Disney+. Want CNET to notify you of price drops and the latest stories? (Assuming the average composition of rock were maintained.). 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. But what if we took just a spoonful of it and transported it to Earth? 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. Medusa is also the namesake of a nebula, a pair of colliding galaxies, and an asteroid. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. Filled with bonkers science, boundless curiosity, and Randall's signature stick-figure comics, What If? This website uses cookies to improve your experience while you navigate through the website. However, were not just worried about the mass in the spoon. Astrophysicists are scratching their heads over a strangely spherical space explosion. 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. 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. The cookie is used to store the user consent for the cookies in the category "Other. A neutron star forms when a main sequence star with between about eight and 20 times the Sun's mass runs out of hydrogen in its core.
