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. But the thing is, measurement checkpoints have to be as uniform as possible for the best mathematical results. How do I get rid of whiteheads on my nose naturally? Inbox, #12, Lose Weight the Slow and Incredibly Difficult Way. And indeed, it is by nine orders of magnitude. [9]Although I wouldn't trust the elevators. Delivered on weekdays. 0:52. "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. 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. How do I move data from one tab to another in Excel? 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). [1] But under the right conditions, you could catch a bullet. Argis13 (talk) 14:18, 25 February 2021 (UTC). These cookies track visitors across websites and collect information to provide customized ads. The second is this neutrino cooling stage, lasting to ~10 5 years. The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. "Supernovii" is discouraged. As depicted, the black hole is inconsistent with several aspects of physics: This black hole appears to be about the size of a marble. GPS timing is incredibly precise; of all the problems in engineering, it's one of the only ones in which engineers have been forced to include both special and general relativity in their calculations. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. However, were not just worried about the mass in the spoon. Gravity varies by this much between different cities already. How long would it take for people to notice their weight gain if the mean radius of the world expanded by 1cm every second? The Only! A sugar cube of neutron star material weighs as . The event would likely shower us in so much high-energy cosmic radiation that it could spark a planetary mass extinction. "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. Inbox, #11, Weird (and Worrying) Questions from the What If? Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 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. Shemozzle 7 yr. ago. Overwhelmingly Large Telescope xkcd comics i enjoy . 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. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. [Editor's note: This article was updated Feb. 23, 2022.]. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. Explanation []. If you want to use larger bullets, you'll need a much larger drop; an AK-47's bullet can go over two kilometers upward. At what point do these two unimaginable things cancel out to produce an effect on a human scale? (Heavier stars produce stellar-mass black holes.) These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. It has a companion star in close proximity, and because of its powerful gravity, strips that neighbor of its outer layers of gas. :P 172.69.63.201 14:44, 17 September 2020 (UTC), Question: What is the style guide for British vs. American Spelling (e.g., Color vs. Colour) in explain xkcd? Each one will cool the air a little bit. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language". What If? Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. 16. Sunday, SpaceX shared photos of a stack of ~790 kg Starlink V2 "minis". 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. 2023 CNET, a Red Ventures company. Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions. 2.3 AU is a little more than the distance between the Sun and Mars. 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. The cookie is used to store the user consent for the cookies in the category "Performance". [2]Which would still be less than 1% of the ants in the world. comics from xkcd. It probably wouldn't stop completely; more likely, it would be drifting sideways at a couple meters per second. The mass sun is 400 times heavier than the mass of the moon. This is a good thing to keep in mind if you buy a digital scale. Where are the best places to see the 2023 and 2024 solar eclipses? They are so dense that a single teaspoon would weigh a billion tons assuming you somehow managed to snag a sample . [10]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. Neutron stars are incredibly dense objects about 10 miles (16 km) across. 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. At least some neutron stars are pulsars, which produce powerful beams . What If chapters. wouldn't work for a few reasons. The idea of neutrino radiation damage reinforces just how big supernovae are. 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. Inbox, #1, Weird (and Worrying) Questions from the What If? 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. (, An invention of Randall's, and a reference to the elves of. Too Perfect. 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. A spherical explosion [provides] much greater precision in the measurement.". Want CNET to notify you of price drops and the latest stories? [5]Karam, P. Andrew. The typical density of neutron stars is . Inbox, #3, Weird (and Worrying) Questions from the What If? At least I think. [7]Just what you want in a skyscraper. NICER is a two-in-one mission. She graduated from New York University in 2018 with a B.A. 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. Paint the Earth February 18, 2014. \[ 0.5\text{ nanosieverts} \times\left ( \frac{1\text{ parsec}}{x}\right )^2 = 5\text{ sieverts} \] On average, out of that massive flood, only one neutrino will "hit" an atom in your body every few years. Spice up your small talk with the latest tech news, products and reviews. 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). 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. The first season is the fifth installment of Phase Four of the Marvel Cinematic Universe. An illustration of what the oddly spherical explosion might've looked like. This work is licensed under a Creative Commons Attribution-NonCommercial 2.5 License. Hoping to cool the atmosphere by opening everyones freezer door at the same time? "Supernovas" is also fine. (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.). It's okay. 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. Red dwarf: 0.09-0.5 R; 0.07-0.3 M, 1500-4000 K, 0.00001-0.05 L. If the atmosphere isn't growing like the land and water are, air pressure would start dropping. Concrete expands and contracts by more than that every day. A neutron star balances gravity with neutron degeneracy pressure. 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. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . The title text is in the style of a Wikipedia page's hatnote / reference note. Statistically, my first neutrino interaction probably happened somewhere around age 10. 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. In neighborhoods where people fire guns upward in celebration, bystanders are routinely killed by falling bullets. No. What would happen if everyone jumped at the same time Xkcd? This page was last edited on 26 May 2022, at 19:45. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. In addition to dust and water, they contain a small amount of CO2, which would be released into the atmosphere as the comet melted. 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. On the other hand, if the atmosphere is also expanding, surface air pressure would rise. This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. Once its nuclear fuel is consumed, the . (Assuming the average composition of rock were maintained.). Well, I'd argue,anything except what scientists just observed. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up . Generally, it turns into heat. 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. "Gamma And Neutrino Radiation Dose From Gamma Ray Bursts And Nearby Supernovae." Geologic activity would also accelerate. 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. This is due to a combination of factors. would change Earth's radiation balance, trapping heat near the surface and raising the planet's temperature. Answer (1 of 22): Summary - This is fictional. The very central region of the star the core collapses, crushing together every proton and electron into a neutron. Only small insects (and sea animals) would be physically able to move around. in Philosophy, Physics and Chemistry. More active plate tectonics might be good for life. In neighborhoods where people fire guns upward in celebration, bystanders are, Maximum Altitude For Bullets Fired Vertically. 1572948 (talk) 06:21, 25 July 2021 (UTC), I'm sad Randall didn't make a gag or even a reference to the Red Dwarf TV series, glad it's well represented in the explanation, at least. A bigger projectile can go further. A tablespoon of the Sun, depending on where you scoop, would weigh about 5 pounds (2 kilograms) the weight of an old laptop. 2 What would happen if a neutron star was placed close to the earth? Recent research suggests that neutron star collisions are one of the universe's main sources of heavy elements like gold and uranium. people had noticed that the continents fit together. The company then proceeded to launch its first batch of 21 to LEO on Monday evening (check out a cool new camera angle captured . For more, see this chapter and this article. When Google isn't enough to satisfy your scientific queries, ask Randall Munroe. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . Imagine you have a can of soda, and its all shaken up. 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.

That size implies a black hole can often swallow a neutron star whole. Manifold Destiny: The One! 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. Join Us in Tucson for Our Annual Public Star Party! 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. "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. [5]Lawrence Grybosky, Thermal Expansion and Contraction. At somewhere around 6 atmospheres, even ordinary air becomes toxic.[13]R.M. You'd probably notice the weight gain, and you'd definitely notice the failure of roads, bridges, power lines, satellites, and undersea cables. 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 . 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. 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. After a month, the Earth would have expanded by 26 kilometersan increase of 0.4%and its mass would have increased by 1.2%. Not as quickly as you might think. All rights reserved. If you succeeded, you might notice something odd: In addition to being hot, the bullet would be spinning. 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. 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. If it's going fast enough, a feather can absolutely knock you over. 66, p.83 After several centuries, it would be close enough to the swollen Earth that the tidal forces between Earth and the Moon would be stronger than the gravitational forces holding the Moon together. 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. "Sir, is this container under 3 ounces?" "Not sure, how much blood is there in a church mouse?" Reply . But all that matter has been compressed to an object about 10 miles (16 kilometers) across. What If? I was raised, Don't do this. 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. 4 min . How do I minimise waste on a flight? articles, published either in Randall Munroe's What If? -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. This cookie is set by GDPR Cookie Consent plugin. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Sun's mass. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. Since you're moving steadily upward at 1 cm/s, you woudn't feel any kind of ongoing acceleration. 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 . Typical properties are shown below. Unfortunately, comets would affect the Earth's temperature in another way. [1]Less often if you're a child, since you have fewer atoms to be hit. Even after a day, the extra 5.4 kilometers would be handled easily by virtually all structures. At this point, astronauts on the ISS would start getting worried. 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. Thus, no matter your gun, youre not shooting a bullet around the Earth. These cookies will be stored in your browser only with your consent.
