This is probably a case of artistic license. The life of super-Earths: how the hunt for alien worlds and artificial cells will revolutionize life on our planet. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. When would the Earth eventually become a black hole? Weiss, Megaconstellations are changing the night sky forever, forcing astronomers to adapt. The Earth is not, currently, expanding. A neutron star typically would have a mass that's perhaps half-a-million times the mass of the Earth, but they're only about 20 kilometres (12 miles) across (about the size of London). The detonation of a hydrogen bomb pressed against your eyeball? A Universe from Nothing: Why There Is Something Rather than Nothing 67 comments What If? Not only would we be unable to move around to find food, but our hearts would be unable to pump blood to our brains. It no longer burns hydrogen, helium . Everest. 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 very central region of the star the core collapses, crushing together every proton and electron into a neutron. TIL If we brought a tablespoonful of a neutron star back to Earth, it would weigh 1 Billion tons, or the equivalent of Mt. There's been a lot of them, and they seem repetitive - no real new humor. Gravity would take a long time to increase. Is political science a good major for law? 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. provide that scenario. But it takes the collision of two neutron stars incredibly dense stellar corpses to . 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. It looks like it should be "1" or something, but it's not. The most common, smallest, and coolest type of true star in the universe. 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). When stars at about the Sun's size begin to run out of fusion fuel, they expand to become red giants, and the outer shells expand and cool. Since you're moving steadily upward at 1 cm/s, you woudn't feel any kind of ongoing acceleration. Less often if you're a child, since you have fewer atoms to be hit. 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.

And by that point, you may find you've attracted some attention. Bottom line: Neutron stars are the collapsed cores of formerly massive stars that have been crushed to an extreme density by supernova explosions. In the scenario where the atmosphere isn't expanding, the air would become thin enough to be difficult to breathe even at sea level. The comet isn't the important part, the crane is. [2] Answer (1 of 17): If we take neutron star material at say a density of 10^{17} kg/m3 the neutrons have an internal kinetic energy density of 310^{32} J/m^3. How do I move data from one tab to another in Excel? Last chance to join our 2020 Costa Rica Star Party! "No one expected the explosion to look like this. What would happen if a neutron star was placed close to the earth? A comet crane generator could cut our energy-related greenhouse gas emissions to almost zero. After a month, the Earth would have expanded by 26 kilometersan increase of 0.4%and its mass would have increased by 1.2%. 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. 2 is sure to be another instant classic adored by inquisitive readers of all ages. 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. Soda Sequestration March 18, 2014. Shortly after 8:41 a.m. EDT on Aug. 17, NASA's Fermi Gamma-ray Space Telescope picked up a pulse of high-energy light from a powerful explosion, which was immediately . Reference Article: Facts about neutron stars. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Suns mass. However, were not just worried about the mass in the spoon. The cookie is used to store the user consent for the cookies in the category "Other. The release of magnetic energy could cause the matter in the explosion to be distributed more spherically. After a few years, the comet's greenhouse effect would have trapped more heat than the ice absorbed, and over the decades to follow, the extra heat would keep piling up. Inbox, #1, Weird (and Worrying) Questions from the What If? Inbox, #10, Weird (and Worrying) Questions from the What If? This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. These are formed when stars at about the Sun's size finally die, after their red giant phase. (, An invention of Randall's, and a reference to the elves of. Although there are some black holes with a mass of 70 times the sun). articles, published either in Randall Munroe's What If? So unless you stood right next to the spoon, you wouldnt notice. After years had passed, the top of Mt. 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. A tablespoon of neutron star weighs more than 1 billion tons (900 billion kg) the weight of Mount Everest. "Knowing what the shape is, is crucial here, because if you have an object that is not spherical, it emits differently, depending on your sight angle. They're like the baby brothers of black holes. "Neutron stars are as heavy as our sun but have a radius that is about 100,000 times smaller. (Full text here.) At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up . 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? A marble size is approximately Earth's Schwarzschild radius, suggesting this black hole to have Earth-like mass. Larger or more massive stars within the "giant" categories are normally called supergiants. Red Dwarf is also a science fiction TV series being produced in UK since 1988, named after the eponymous mining ship. 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! 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. A real star type. It's like the idiom "knock me over with a feather" or the phrase "football stadium filled to the brim with ants". What If chapters. Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. A sugar cube of neutron star material weighs as . They are extremely dense and no longer undergo nuclear fusion. 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 For most of them, the limiting factor isn't weight, but wind. But what if we took just a spoonful of it and transpo. Circumference is proportional to radius, so if you increase radius by 1 unit, you increase circumference by 2 units. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. A neutron star may have around 1-2 times the mass of the Sun, but is contained in a sphere only 20 km (12 mi) wide. The star starts fusing helium to carbon, like lower-mass stars. The neutron star, a pulsar designated PSR J0952-0607, is thus the densest object within sight of Earth. 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. Before publishing the first what if? This is (currently) the main way global warming is raising the sea level. Argis13 (talk) 14:18, 25 February 2021 (UTC). Monisha Ravisetti. 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. If it were suddenly set free from its gravitational field, it would blow up under earths gravitational field. [1]Less often if you're a child, since you have fewer atoms to be hit. Inbox, #2, Weird (and Worrying) Questions from the What If? But what if we took just a spoonful of it and transported it to Earth? Core collapse supernovae happen to giant stars, so if you observed a supernova from that distance, you'd probably be inside the outer layers of the star that created it. 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. 2 is sure to be another instant classic adored by inquisitive readers of all ages. 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. 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. This would be very brief. Small chunks of ice falling from space disintegrate and boil away before they reach the ground, warming the upper atmosphere. Not as quickly as you might think. 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. 16. When wateror anything elsefalls, it gains kinetic energy. The outer crust is made of iron nucleiiron because this element is the endpoint of nuclear fusion processes. Trees would collapse. A tablespoon of the Sun, depending on where you scoop, would weigh about 5 pounds (2 kilograms) the weight of an old laptop. All human structures will stay. Which would still be less than 1% of the ants in the world. 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. Inbox, #3, Weird (and Worrying) Questions from the What If? By signing up you may also receive reader surveys and occasional special offers. Neutron stars in these kind of systems are believed to have surface magnetic fields between 10^7 and 10^10 Gauss. A tablespoon of a neutron star weights about 1 billion tons. 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. It premiered on August 11, 2021 and concluded on October 6, 2021. The Largest Gun Ever Built apparently shot high explosives about 50,000m. xkcd.com. 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. A real thing, though not a true star, but a remnant of one. You'd have to grab the bullet firmly; otherwise, it might jump out of your hand.

Inbox, #8, Weird (and Worrying) Questions from the What If? Magical storks deliver babies, magical cranes deliver comets. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. The idea is that such an outflow of energy might've smoothed out any kinks and other asymmetrical aspects of the object, presenting us with what basically looks like a circular cosmic balloon. But without it, we go nowhere.\" Carl SaganIf you enjoy What If, make sure to check out our other channel \"Underknown\": https://www.youtube.com/c/interestingshitProduced by Underknown in Toronto, What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. When it comes to shape, though, neutron star collisions seem to be key. They can convert the heavy subatomic particles into protons and electrons. View our Privacy Policy. Sunday, SpaceX shared photos of a stack of ~790 kg Starlink V2 "minis". You also have the option to opt-out of these cookies. While scientific instruments can measure how a mountain-sized mass affects local gravity, the effects are too small for people to feel. 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. Some types of stars can vary in a wide range of sizes as well. 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. Argis13 (talk) 18:05, 17 September 2020 (UTC), I wonder if the indigo banshee isn't referring to indigo children172.69.34.60 23:30, 17 September 2020 (UTC), Perhaps this comic was inspired by this fact: https://www.zdnet.com/article/20-years-of-linux-on-big-iron/ Over time, the surface cools, but while the surface is still hot enough, it can be seen with X-ray telescopes. Outside of low-pressure domes, the air would become unbreathable for a different reason. [Editor's note: This article was updated Feb. 23, 2022.]. 2023 CNET, a Red Ventures company. A bullet fired straight up would eventually reach a maximum height. 2.3 AU is a little more than the distance between the Sun and Mars. Surprisingly, most skyscrapers would hold up fine under much higher gravity. [4]Floor water. xkcd.com; what if? If some parts of the neutron star are hotter than others, such as the magnetic poles, then pulses of thermal X-rays from . Anybody know why? This is due to a combination of factors. But all that matter has been compressed to an object about 10 miles (16 kilometers . Maybe its time for a brief introduction to thermodynamics. These cookies ensure basic functionalities and security features of the website, anonymously. After 100 years, we'd be experiencing over six gees of gravity. Enforced by Radar March 11, 2014.

Feb. 17, 2023 10:28 a.m. PT. 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. 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. This would be similar to the situation on Earth billions of years ago, when we had more radioactive material and thus a hotter mantle. Therefore, only the surfaces can cool by the emission of such radiation. Alternative title. Gamma And Neutrino Radiation Dose From Gamma Ray Bursts And Nearby Supernovae. 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. All rights reserved. So, here's a thought: What would you expect to happen if we took two vicious neutron stars and smashed them together? How do I minimise waste on a flight? If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. 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. Toxicity aside, breathing dense air is difficult simply because it's heavy. neutron star: [noun] a dense celestial object that consists primarily of closely packed neutrons and that results from the collapse of a much larger stellar body. What If? Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. 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. Comets are more dust than ice, but they're not particularly dense. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. Its like adding another mountain. 162.158.103.125 11:30, 17 September 2020 (UTC), Teal Sphinx? I make mistakes, I am out of control and at times hard to handle. The event would likely shower us in so much high-energy cosmic radiation that it could spark a planetary mass extinction. 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. A real star type. Planning to ride a fire pole from the moon back to Earth? People have long suggested that it might be. New York: Basic Books, 2012.

We can use the Doppler effect to measure the orbital motion of a pulsar. "Supernovas" is also fine. Geologic activity would also accelerate. In that case, the birth of the black hole may be very energetic.". A tablespoon of a neutron star weights about 1 billion tons. But since that air is spread out over a larger area, the overall effect would be decreasing air pressure. 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. Imagine you have a can of soda, and its all shaken up. 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. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . On the other hand, since you'd be heavierand the mountain would be tallerclimbing would be more work. 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. The idea of neutrino radiation damage reinforces just how big supernovae are. NICER is a two-in-one mission. 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. After 40 years, Earth's surface gravity would have tripled. No matter what, you do not want to find yourself near a neutron star. where m is the mass of the neutron and h is Planck's constant. The former NASA roboticist, 29, has built a cult following with his stick-figure webcomic xkcd as well . "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. After five years, gravity would be 25% stronger. and gently set the comet in the ocean. Too Perfect. But under the right conditions, you could catch a bullet. 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. . Enter the Space & Beyond Box Photo Contest! 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. 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. The story icomes from a National Geographic video. The pressure inside planets is roughly proportional to the square of their surface area, so the Earth's core would be squeezed tightly. As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. 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. For more, see this chapter and this article. ''Your stupid!''. A 3D illustration of a neutron star in the nebula. 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? A paper by radiation expert Andrew Karam provides an answer. (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.). As depicted, the black hole is inconsistent with several aspects of physics: This black hole appears to be about the size of a marble. 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. xkcd.com; what if? 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. Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. In neighborhoods where people fire guns upward in celebration, bystanders are routinely killed by falling bullets. [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). would be around half a nanosievert, or 1/500th the dose from eating a banana.[7]xkcd.com/radiation. e.g. Necessary cookies are absolutely essential for the website to function properly.

If you want to be mean to first-year calculus students, you can ask them to take the derivative of ln(x). You might notice the difference in weight on a scale, but it's not a big deal. It does not store any personal data. 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. [3]Don't do this. Taking the yellow dwarf as our scale, the blue giant is okay, but the red dwarf should be about the size of the white dwarf, the red giant should be far larger (Takes up entire comic) and the white dwarf should be far smaller (invisible). The cause of the collapse would be the expanding ground below them, not the increased gravity. 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. This Neutron Star Explosion Was Perfect. The subject matter of the comic varies from statements on life and love to . [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. Your pendulum clock would now be ahead by five days. . (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . When our sun enters this phase in a few billion years, it will consume Mercury, Venus, and possibly the Earth. "Supernovii" is discouraged. In addition to dust and water, they contain a small amount of CO2, which would be released into the atmosphere as the comet melted. His 2014 book What If? comics from xkcd. If you don't have a balloon, you could potentially make this work from a mountain peak. Crops wouldn't stand up under their own weight. Explain xkcd: It's 'cause you're dumb. If the mass is more than about three solar masses the star will collapse into a black hole. Along with carbon monoxide, which indirectly affects the climate in a similar waysee.
