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. 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. 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. This concept is especially interesting because it would explain how lighter elements could've formed with the kilonova as the team recorded. The cookie is used to store the user consent for the cookies in the category "Performance". Lightcaller (talk) 01:55, 17 September 2020 (UTC), Wat. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Sun's mass. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! The first season is the fifth installment of Phase Four of the Marvel Cinematic Universe. Colliding neutron stars decapitate zombie theory of . A giant star faces several possible fates when it dies in a supernova. 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. Perhaps humans could survive in specially-built controlled-pressure domes, moving around by keeping most of our bodies submerged in water. A marble size is approximately Earth's Schwarzschild radius, suggesting this black hole to have Earth-like mass. When it comes to shape, though, neutron star collisions seem to be key. Franz and P.C. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. [Editor's note: This article was updated Feb. 23, 2022.]. Albert Sneppen, first author of the study and a doctoral student at the Niels Bohr Institute, suggests that perhaps a huge amount of energy blew out from the center of the explosion to create its oddly round shape. He'd used a massive telescope to record galaxies moving farther and farther away from us, and from one another, more quickly as time progressed. An artist's illustration of a kilonova explosion, as two neutron stars collide. They're like the baby brothers of black holes. This is a list of What If? People have long suggested that it might be. After the first day, the Earth would have expanded by 864 meters. Well, I'd argue,anything except what scientists just observed. The most common, smallest, and coolest type of true star in the universe. 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. 162.158.158.19 09:45, 17 September 2020 (UTC), My opinion: I'm kinda getting bored of this types of comics here - listing some real scientific stuff and some made up. The nuclei get pressed close together so . Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions, The smoking gun that confirmed the plate tectonics hypothesis was the discovery of, Mass is proportional to radius cubed, and gravity is proportional to mass times inverse square of radius, so radius, Over decades, the force of gravity would grow slightly faster than you'd expect, since the material in the Earth would compress under its own weight. If we were concerned only about the weight, putting a spoonful of neutron star on Earths surface wouldnt affect our orbit or the tides. But harvesting orbital energy like this is a neat idea! After 10 years, gravity would be 50% stronger. See table below. Order here! 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). Join us on an imaginary adventure grounded in scientific theory through time, space and chance, as we ask what if some of the most fundamental aspects of our existence were different.Feedback, inquiries and suggestions: https://underknown.com/contact Eventually, they would have to break up, right? would be around half a nanosievert, or 1/500th the dose from eating a banana.[7]xkcd.com/radiation. What would happen if a neutron star was placed close to the earth? This theory was never very widespread,[3]It turns out it's kind of dumb. 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 . Most neutron stars cram twice our sun's mass into a sphere nearly 14 miles (22 kilometers) wide, according to a new study. After a month, the Earth would have expanded by 26 kilometersan increase of 0.4%and its mass would have increased by 1.2%. 718-719 of the IPCC WG1 AR5 report for more. This Neutron Star Explosion Was Perfect. 08.23.07. 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. Inbox, #3, Weird (and Worrying) Questions from the What If? Hercules X-1 isn't alone in space. This is (currently) the main way global warming is raising the sea level. wouldn't work for a few reasons. Neutron stars squeeze up to two solar masses into a city-size volume, giving rise to the highest stable densities known anywhere. However, if you have a very precise pendulum clock, you might notice something oddby the end of the day, it would be three seconds ahead of where it should be. [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. 162.158.103.125 11:30, 17 September 2020 (UTC), Teal Sphinx? 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? A 3D illustration of a neutron star in the nebula. Before publishing the first what if? 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. A tablespoon of a neutron star weights about 1 billion tons. Once its nuclear fuel is consumed, the . 4 min . The hardest part is sticking the landing. This cookie is set by GDPR Cookie Consent plugin. Neutron stars are incredibly dense objects about 10 miles (16 km) across. Sunday, SpaceX shared photos of a stack of ~790 kg Starlink V2 "minis". "Gamma And Neutrino Radiation Dose From Gamma Ray Bursts And Nearby Supernovae." Gravity varies by this much between different cities already. If you set the comet on land, it would soak up heat from the atmospherewhich contains much less stored heat than the oceansbriefly cooling the air by an average of one or two thousandths of a degree. 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. Inbox, #5, Weird (and Worrying) Questions from the What If? [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. The comet isn't the important part, the crane is. provide that scenario. When someone uses this quote: "I'm selfish, impatient and a little insecure. Therefore, only the surfaces can cool by the emission of such radiation. "Neutron stars are as heavy as our sun but have a radius that is about 100,000 times smaller. DeathNoteRs 7 yr. ago. The phrase "lethal dose of neutrino radiation" is a weird one. At that speed, as long as you were in the right place at the right time, you could snatch it out of the air. The cookie is used to store the user consent for the cookies in the category "Other. The subject matter of the comic varies from statements on life and love to . (Stars with higher masses will continue to collapse into stellar-mass black holes.). This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. Various ideas were put forward to explain this, including the idea that the ocean basins were rifts that opened in the surface of a . View our Privacy Policy. Blue giant: 2-400 R; 2-300 M, 8000-60000 K, 15-10000000 L. At this point, even the strongest humans would only be able to walk with great difficulty. "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. 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. 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 neutron star, a pulsar designated PSR J0952-0607, is thus the densest object within sight of Earth. You'd have to grab the bullet firmly; otherwise, it might jump out of your hand. 172.68.24.130 11:02, 30 November 2020 (UTC), No, not really. A spherical explosion [provides] much greater precision in the measurement.". (Full text here.) A neutron star balances gravity with neutron degeneracy pressure. A supernova radiates 10 times more neutrinos than there are particles, protons, neutrons and electrons in the sun. Your pendulum clock would now be ahead by five days. [4]Floor water. All rights reserved. But what if we took just a spoonful of it and transpo. 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. The neutron stars we can observe average about 1.8 million degrees Fahrenheit, compared to about 9,900 degrees Fahrenheit for the Sun. How close would you have to be to a supernova to get a lethal dose of neutrino radiation? No. 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. And apols again to the first explained who seemed to appreciate their submission as only a placeholder so I overwrote rather than integrated. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. How do I move data from one tab to another in Excel? 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. 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. 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. That was unexpected. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. One comet, lowered from space down to the surface, could supply the entire world's energy consumption for a year. When our sun enters this phase in a few billion years, it will consume Mercury, Venus, and possibly the Earth. Enter the Space & Beyond Box Photo Contest! With a large enough supply of comets, we can keep the Earth nice and cool, as long as we make sure they're lowered slowly. The star starts fusing helium to carbon, like lower-mass stars. Okay, if you insist. According to a 2016 study, supernovae occurring as close as 50 light-years from Earth could pose an imminent danger to Earths biospherehumans included. 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. After a year, gravity would be 5% stronger. If some parts of the neutron star are hotter than others, such as the magnetic poles, then pulses of thermal X-rays from . is a blog hosted on the xkcd.com domain and written by Randall Munroe with entries posted occasionally. NICER is a two-in-one mission. Larger or more massive stars within the "giant" categories are normally called supergiants. They'd need to evacuate quickly; they'd have at most a few months before the station reentered the atmosphere and deorbited. and more Earth means more heat. I was raised, Don't do this. Statistically, my first neutrino interaction probably happened somewhere around age 10. Star Sand February 11, 2014. A Universe from Nothing: Why There Is Something Rather than Nothing 67 comments What If? Each one will cool the air a little bit. At some point, our growing Earth would reach the point where adding more mass causes it to contract, rather than expand. Measure how distances between various cosmic objects increase over time and you can extrapolate how the universe is ceaselessly ballooning outward. However, you may visit "Cookie Settings" to provide a controlled consent. After five years, gravity would be 25% stronger. 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. Neutron stars have an important role in the universe. By clicking Accept All, you consent to the use of ALL the cookies. "No one expected the explosion to look like this. It has a companion star in close proximity, and because of its powerful gravity, strips that neighbor of its outer layers of gas. How do I minimise waste on a flight? [14]Plummer, H. C., Note on the motion about an attracting centre of slowly increasing mass, Monthly Notices of the Royal Astronomical Society, Vol. Outside of low-pressure domes, the air would become unbreathable for a different reason. Unfortunately, comets would affect the Earth's temperature in another way. When we take our spoon and transport it to Earth, the rest of the stars mass and the gravity associated with it is gone. This would be very brief. Red giant: 3-2000 R; 0.3-50 M, 2500-4000 K, 0.3-650000 L. This website uses cookies to improve your experience while you navigate through the website. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. Imagine you have a can of soda, and its all shaken up. 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. No observers of any of these celestial bodies have been petrified. still have questions, and those questions are getting stranger. At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up . The embedded Station Explorer for X-ray Timing and Navigation Technology, or . Shemozzle 7 yr. ago. Explain xkcd: It's 'cause you're dumb. The reason you don't notice the neutrino flood is that neutrinos hardly interact with ordinary matter at all. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. Filled with bonkers science, boundless curiosity, and Randall's signature stick-figure comics, What If? [5]Lawrence Grybosky, Thermal Expansion and Contraction. 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! Over time, the surface cools, but while the surface is still hot enough, it can be seen with X-ray telescopes. 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. At somewhere around 6 atmospheres, even ordinary air becomes toxic.[13]R.M. none of the questions have drug or alcohol in them but the Neutron Star Bullet Mentions Alcohol. What If? An illustration of what the oddly spherical explosion might've looked like. Generally, it turns into heat. But what if we took just a spoonful of it and transported it to Earth? The very central region of the star the core collapses, crushing together every proton and electron into a neutron. 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'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. Since the volume expands faster than the surface area, the overall heat flowing out per square meter will increase. Inbox, #11, Weird (and Worrying) Questions from the What If? Last chance to join our 2020 Costa Rica Star Party! As such, they are the densest objects in the universe. All Rights Reserved 2022 Theme: Promos by. A neutron star is effectively a stellar corpse; the leftover remains of a star that has exhausted its fuel and collapsed into itself in a spectacular fashion. 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. Crops wouldn't stand up under their own weight. View our Privacy Policy. Soda Sequestration March 18, 2014. A stone si. Using the inverse-square law, we can calculate the radiation dose: She covers climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical thought experiments. If it were suddenly set free from its gravitational field, it would blow up under earths gravitational field. 162.158.158.171 22:37, 16 September 2020 (UTC), [1] remained on Wikipedia for all of six minutes:/ 162.158.62.149 23:40, 16 September 2020 (UTC), Ten minutes, surely?
