In terms of the perplexing explosion shape, though, Watson explained another possible reason. In short, the answer to Grey's question is yes 500 mph winds would send you flying through the air. Okay, so we just need thousands of comets, right? After the first day, the Earth would have expanded by 864 meters. That's why this is a neat question; supernovae are unimaginably huge and neutrinos are unimaginably insubstantial. [9]Although I wouldn't trust the elevators. New York: Basic Books, 2012. 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. "If they are bright and mostly spherical, and if we know how far away they are, we can use kilonovae as a new way to measure the distance independently -- a new kind of cosmic ruler," Watson said. Delivered on weekdays. The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. 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. Concrete expands and contracts by more than that every day. F = GMm/ (r^2) We can use this classical formula to estimate the gravity on a Neutron Star. The phrase "lethal dose of neutrino radiation" is a weird one. [4]Floor water. This website uses cookies to improve your experience while you navigate through the website. It premiered on August 11, 2021 and concluded on October 6, 2021. Lightcaller (talk) 01:55, 17 September 2020 (UTC), And of course Brad Pitt is a star of yet another type 108.162.215.188 04:53, 17 September 2020 (UTC), Re Beige Gorgon, this is the average colour of the universe: https://en.wikipedia.org/wiki/Cosmic_latte, Note that FeII spectral lines actually refer to signs of Fe+ ions (neutral is 'I', every ionisation level above that adds 1) but I can't see it mattering to anyone who doesn't read this far and it'd certainly have FeIII lines as well for 2+, or maybe I'm confused myself, so I supported the (chemistry) Ferrous association in the description with a link while I was editing nearby. 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. This cookie is set by GDPR Cookie Consent plugin. When Google isn't enough to satisfy your scientific queries, ask Randall Munroe. The mass of the sun is 1.989 10 30 kg while the mass of the moon is 7,348 * 10 22 kg. 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. I had to turn it over in my head a few times after I heard it. Outside of low-pressure domes, the air would become unbreathable for a different reason. Not only would the ground (and atmosphere) be rising toward them, but the increased gravity would also cause their orbit to slowly shrink. [1]This was confirmed by Mythbusters in episode 4 of Season 4. After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. Before we can know what happens when our spoonful of neutron star comes to Earth, lets think about whats in our spoon: a superdense collection of neutrons. At least some neutron stars are pulsars, which produce powerful beams . Virtually every mountainside would see massive landslides as material sought out a shallower angle of repose. 0:52. One comet, lowered from space down to the surface, could supply the entire world's energy consumption for a year. Gravity varies by this much between different cities already. Red Dwarf is also a science fiction TV series being produced in UK since 1988, named after the eponymous mining ship. 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. 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. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances.

In fact, it's honestly sort of impressive to find a solution that would actively make the problem worse in so many different ways. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. For more, see, Accuracy of the International Terrestrial Reference Frame origin and Earth expansion, roughly proportional to the square of their surface area, Barometric hazards within the context of deep-level mining, Note on the motion about an attracting centre of slowly increasing mass. Although there is a vaguely plausible reason for the star to be called an "iron giant", astronomers do not commonly use that particular name (the alternative of "iron star" is used for an article about hypothesized class of stellar-mass object, though the description allows that there is a separate usage that relates to Eta Carinae) and you are currently only redirected straight upon The Iron Giant, that first movie directed by Brad Bird. Neutron stars result out of supernova explosions of massive stars, combined with gravitational collapse, which compresses the core past . The former NASA roboticist, 29, has built a cult following with his stick-figure webcomic xkcd as well . All human structures will stay. (Heavier stars produce stellar-mass black holes.) 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. But all that matter has been compressed to an object about 10 miles (16 kilometers) across. Could I cool down the Earth by capturing a comet and dropping it in the ocean, like an ice cube in a glass of water? On the other hand, since you'd be heavierand the mountain would be tallerclimbing would be more work. This cookie is set by GDPR Cookie Consent plugin. As gravity increases, then air gets heavier. 2.3 AU is a little more than the distance between the Sun and Mars. What If? A tablespoon of a neutron star weights about 1 billion tons. 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. We also use third-party cookies that help us analyze and understand how you use this website. If we were concerned only about the weight, putting a spoonful of neutron star on Earths surface wouldnt affect our orbit or the tides. At some point, our growing Earth would reach the point where adding more mass causes it to contract, rather than expand. So unless you stood right next to the spoon, you wouldnt notice. Feb. 17, 2023 10:28 a.m. PT. "Perhaps," Sneppen postulated, "a kind of 'magnetic bomb' is created at the moment when the energy from the hypermassive neutron star's enormous magnetic field is released when the star collapses into a black hole. According to a 2016 study, supernovae occurring as close as 50 light-years from Earth could pose an imminent danger to Earths biospherehumans included. Neutron stars typically have a radius of 10 km / 6.2 mi and a mass of around 1.4 to 3.2 solar masses. 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. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. This is a list of What If? His 2014 book What If? Neutron stars are phenomenally dense. One is that dropping things from space creates heat. You'd probably notice the weight gain, and you'd definitely notice the failure of roads, bridges, power lines, satellites, and undersea cables. See table below. In the case of neutron decay, about 0.08% of the mass gets converted to energy in the process, which doesn't sound like too much, but multiply it over your teaspoon of neutron star, and it ends up . Most buildings would probably be ok, although those anchored firmly into bedrock might start to behave unpredictably. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. 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. It would just take a lot of patience. Rocket Golf February 25, 2014. [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). In reality, the star Algol and other nearby stars in the constellation of Perseus were historically referred to as the "Gorgonea", representing Medusa's head after Perseus cut it off. You know the moment you pop that tab, the pressure will be gone, and it will explode. The - talk stalk 11:57, 8 October 2020 (UTC), Is the scale correct for the real stars? How close would you have to be to a supernova to get a lethal dose of neutrino radiation? If it comes down to a vote, I think that we should stick with American spelling in general, because Randall is American. As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. At this point, the star is simply getting . 172.68.24.130 11:02, 30 November 2020 (UTC), No, not really. 08.23.07. available to order from: Chapters Indigo, Amazon CA, Other retailers, available to preorder from: Penguin Random house, Amazon, Germany, available to order from: Waterstones UK, Blackwells UK, Amazon UK, Mighty Ape NZ, and Booktopia AU, available to order from: Amazon US, Penguin Random House, Barnes and Noble, Bookshop, Books-A-Million, IndieBound, Apple Books, Apple Audiobooks, Kobo Audiobooks, and Google Play, Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems. A supernova radiates 10 times more neutrinos than there are particles, protons, neutrons and electrons in the sun. After a month, the Earth would have expanded by 26 kilometersan increase of 0.4%and its mass would have increased by 1.2%. It probably wouldn't stop completely; more likely, it would be drifting sideways at a couple meters per second. After a year, gravity would be 5% stronger. "Supernovii" is discouraged. "Supernovas" is also fine. Neutron stars are made in supernova explosions which are giant neutrino factories. 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. When would the Earth eventually become a black hole? Crops wouldn't stand up under their own weight. A tablespoon of the Sun, depending on where you scoop, would weigh about 5 pounds (2 kilograms) the weight of an old laptop. Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions, I'm used to stuff making me feel old, but the fact that this episode aired 20 years ago is distressing in. Soda Sequestration March 18, 2014. 718-719 of the IPCC WG1 AR5 report for more. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! But under the right conditions, you could catch a bullet. Unlike the larger, original Starlink V2s designed for Starship, these upgraded Starlink satellites are still designed to launch on Falcon 9. What would happen if everyone on earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant? [1]Yes, I have a citation for this. Neutron stars pack their mass inside a 20-kilometer (12.4 miles) diameter. 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. Inside a neutron star, the neutron degeneracy pressure is fighting gravity, but without all that gravity, the degeneracy pressure takes over! 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. 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). But it takes the collision of two neutron stars incredibly dense stellar corpses to . Since you're moving steadily upward at 1 cm/s, you woudn't feel any kind of ongoing acceleration. (Stars with higher masses will continue to collapse into stellar-mass black holes.). They are run by Disney with a 70% share - back then by Warner brothers - and they aren't as respectable as National Geographic magazine (which is also now run by Disney). Order here! wouldn't work for a few reasons. Filled with bonkers science, boundless curiosity, and Randall's signature stick-figure comics, What If? Schutte, Barometric hazards within the context of deep-level mining, The Journal of The South African Institute of Mining and Metallurgy Even if we'd managed to survive all the other problems, by 100 years, we'd be dead from oxygen toxicity. They'd need to evacuate quickly; they'd have at most a few months before the station reentered the atmosphere and deorbited. So, perhaps the neutron stars' neutrons got converted? Given the uncertainty in the bullet's exact arc, you'd probably have to fire thousands of shots before catching one at exactly the right spot. A tablespoon of a neutron star weights about 1 billion tons. [3]Don't do this. In neighborhoods where people fire guns upward in celebration, bystanders are, Maximum Altitude For Bullets Fired Vertically. Can a planet still function with a damaged moon? Red dwarf: 0.09-0.5 R; 0.07-0.3 M, 1500-4000 K, 0.00001-0.05 L. in Philosophy, Physics and Chemistry. 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. [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. However, were not just worried about the mass in the spoon. This cookie is set by GDPR Cookie Consent plugin. I make mistakes, I am out of control and at times hard to handle. comics from xkcd. more from Astronomy's weekly email newsletter. 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). By signing up you may also receive reader surveys and occasional special offers. 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. Reference Article: Facts about neutron stars. But harvesting orbital energy like this is a neat idea! Stretching a 40,000-kilometer line an extra 6.28 meters is pretty negligible. Everest would no longer be in the "death zone". Neutron stars have an important role in the universe. What If chapters. 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 #1 New York Timesbestselling author of What If? A full-size comet wouldn't be strong enough to support its own weight, and would collapse like a drying sand sculpture. This crowd takes up an area the size of Rhode Island. Trees would collapse. Lightcaller (talk) 01:55, 17 September 2020 (UTC), Wat. The CO2 released from the comet would raise the temperature of the Earth for centuries. 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. 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. articles, published either in Randall Munroe's What If? Star Sand February 11, 2014. This is a list of What If? Health Physics 82, no. Inbox, #11, Weird (and Worrying) Questions from the What If? Colliding neutron stars decapitate zombie theory of . More details.. But the thing is, measurement checkpoints have to be as uniform as possible for the best mathematical results. For more, see this chapter and this article. 2 What would happen if a neutron star was placed close to the earth? On the other hand, if the atmosphere is also expanding, surface air pressure would rise. 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. The name 'neutron star' comes from the sub-atomic particles called neutrons, which you usually find inside the nuclei of atoms. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Suns mass. How do you prevent jellyfish stings when swimming? feed 2022 . : Serious Scientific Answers to Absurd Hypothetical Questions A neutron star balances gravity with neutron degeneracy pressure. 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. 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. "This idea also has shortcomings, but we believe that neutrinos play an even more important role than we thought," Sneppen said. 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! It's hard to suck in air against the weight of the water, which is why snorkels can only work when your lungs are near the surface. A bullet fired straight up would eventually reach a maximum height. For most of them, the limiting factor isn't weight, but wind. Monisha Ravisetti is a science writer at CNET. Small chunks of ice falling from space disintegrate and boil away . Hall thrusters go argon with Starlink V2 mini. A paper by radiation expert Andrew Karam provides an answer. Magical storks deliver babies, magical cranes deliver comets. 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. Red giant: 3-2000 R; 0.3-50 M, 2500-4000 K, 0.3-650000 L. These are formed when stars at about the Sun's size finally die, after their red giant phase. Res. Since the volume expands faster than the surface area, the overall heat flowing out per square meter will increase. If you succeeded, you might notice something odd: In addition to being hot, the bullet would be spinning. If you weighed 70 kg when the expansion started, you'd weigh 88 kg now. This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. Neutron stars squeeze up to two solar masses into a city-size volume, giving rise to the highest stable densities known anywhere. Not as quickly as you might think. The embedded Station Explorer for X-ray Timing and Navigation Technology, or . 125. 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. The reason you don't notice the neutrino flood is that neutrinos hardly interact with ordinary matter at all. Hoping to cool the atmosphere by opening everyones freezer door at the same time? The pressure inside planets is, 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. Sunday, SpaceX shared photos of a stack of ~790 kg Starlink V2 "minis". This would be similar to the situation on Earth billions of years ago, when we had more radioactive material and thus a hotter mantle. This an illusion, of course; it's not possible to catch a bullet like that. How do I get rid of whiteheads on my nose naturally? Hercules X-1 isn't alone in space. If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. While a normal black hole has the mass of 9.945e+30 (five times the sun. You might notice the difference in weight on a scale, but it's not a big deal. Season 4 radius of 10 km / 6.2 mi and a mass of around 1.4 3.2.
