Neutron stars typically have a radius of 10 km / 6.2 mi and a mass of around 1.4 to 3.2 solar masses. would be around half a nanosievert, or 1/500th the dose from eating a banana.[7]xkcd.com/radiation. [9]Although I wouldn't trust the elevators. How close would you have to be to a supernova to get a lethal dose of neutrino radiation? 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. 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. This would be similar to the situation on Earth billions of years ago, when we had more radioactive material and thus a hotter mantle. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. 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. What would happen if a neutron star was placed close to the earth? 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. Franz and P.C. 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. Less often if you're a child, since you have fewer atoms to be hit. -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. : Serious Scientific Answers to Absurd Hypothetical Questions 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. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! \[ x=0.00001118\text{ parsecs}=2.3\text{ AU} \] Inbox, #1, Weird (and Worrying) Questions from the What If? A giant star faces several possible fates when it dies in a supernova. Toxicity aside, breathing dense air is difficult simply because it's heavy. Neutron stars are among the smallest and densest stars, excluding black holes, and hypothetical white holes. 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 . 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. The title text is in the style of a Wikipedia page's hatnote / reference note. Paint the Earth February 18, 2014. The first season is the fifth installment of Phase Four of the Marvel Cinematic Universe. Shemozzle 7 yr. ago. A spherical explosion [provides] much greater precision in the measurement.". 2 is sure to be another instant classic adored by inquisitive readers of all ages. Okay, if you insist. Order here! A full-size comet wouldn't be strong enough to support its own weight, and would collapse like a drying sand sculpture. Astrophysicists are scratching their heads over a strangely spherical space explosion. So, perhaps the neutron stars' neutrons got converted?

"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. If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. Geologic activity would also accelerate. What If? The way seafloor spreading and magnetic pole reversal neatly confirmed each other is one of my favorite examples of scientific discovery at work. \[ 0.5\text{ nanosieverts} \times\left ( \frac{1\text{ parsec}}{x}\right )^2 = 5\text{ sieverts} \] 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. Spice up your small talk with the latest tech news, products and reviews. What is the process that creates a neutron star? would change Earth's radiation balance, trapping heat near the surface and raising the planet's temperature. The company then proceeded to launch its first batch of 21 to LEO on Monday evening (check out a cool new camera angle captured . That's why the phrase "lethal dose of neutrino radiation" sounds weirdit mixes scales in an incongruous way. 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/ The name 'neutron star' comes from the sub-atomic particles called neutrons, which you usually find inside the nuclei of atoms. 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. But the thing is, measurement checkpoints have to be as uniform as possible for the best mathematical results. On the other hand, since you'd be heavierand the mountain would be tallerclimbing would be more work. 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. Necessary cookies are absolutely essential for the website to function properly. 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. Mount Thor, which you may remember from question #51, features a vertical drop of 1,250 meters. Article title. Bottom line: Neutron stars are the collapsed cores of formerly massive stars that have been crushed to an extreme density by supernova explosions. Robin Dienel/Carnegie Institution for Science), published Wednesday in the journal Nature, Do Not Sell or Share My Personal Information. Large comets can reach the ground intact and be vaporized on impact as their kinetic energy is converted to heat all at once. Reminds me of an XKCD joke. 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? 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). 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. 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. 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). 16. When it comes to shape, though, neutron star collisions seem to be key. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language". 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. After 10 years, gravity would be 50% stronger. After 40 years, Earth's surface gravity would have tripled. [4]Floor water. Alternative title. Therefore, only the surfaces can cool by the emission of such radiation. If you have a math background, it's sort of like seeing the expression "ln(x)e"it's not that, taken literally, it doesn't make sense, but it's hard to imagine a situation where it would apply. This is probably a case of artistic license. and How To provides his best answers yet to the weirdest questions you never thought to ask. #HowTheUniverseWorksA neutron star is one of the most dangerous objects in the universe. Red giant: 3-2000 R; 0.3-50 M, 2500-4000 K, 0.3-650000 L. No matter what, you do not want to find yourself near a neutron star. 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 . Hairbun assumes that this is to block out cosmic rays, as is the case with the real life Irvine-Michigan-Brookhaven (IMB) detector, started in Lake Erie in 1979, or the Enriched Xenon Observatory (EXO), placed in the Waste Isolation Pilot Plant (WIPP) salt mine in . A neutron star balances gravity with neutron degeneracy pressure. In short, the answer to Grey's question is yes 500 mph winds would send you flying through the air. 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. The pressure inside planets is roughly proportional to the square of their surface area, so the Earth's core would be squeezed tightly. e.g. The Earth is not, currently, expanding. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out!

How do I minimise waste on a flight? Can a planet still function with a damaged moon? [1] But under the right conditions, you could catch a bullet. Thus, no matter your gun, youre not shooting a bullet around the Earth. Eventually, they would have to break up, right? This is a list of What If? 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. We also use third-party cookies that help us analyze and understand how you use this website. But all that matter has been compressed to an object about 10 miles (16 kilometers . This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. Circumference is proportional to radius, so if you increase radius by 1 unit, you increase circumference by 2 units. xkcd.com. Neutron stars are massive gravitational monsters, and orbiting one wouldn't end up well for our planet. (, An invention of Randall's, and a reference to the elves of. 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. This means you're free to copy and share these comics (but not to sell them). Everest would no longer be in the "death zone". That's why this is a neat question; supernovae are unimaginably huge and neutrinos are unimaginably insubstantial. 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 . We do not sell, rent or trade our email lists. 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. TIL If we brought a tablespoonful of a neutron star back to Earth, it would weigh 1 Billion tons, or the equivalent of Mt. If a bullet with the density of a neutron star were fired from a . 125. 2023 CNET, a Red Ventures company. Its like adding another mountain. While a normal black hole has the mass of 9.945e+30 (five times the sun. And indeed, it is by nine orders of magnitude. No observers of any of these celestial bodies have been petrified.

It would just take a lot of patience. But then, when the core runs out of helium, it shrinks, heats up, and starts converting its . This page was last edited on 30 December 2022, at 22:23. Everest. Can a job not hire you because of anxiety? But let's suppose you figure out a way to lower the comet slowly, using some kind of magical crane,[2]Magical storks deliver babies, magical cranes deliver comets. Death from Above. When our sun enters this phase in a few billion years, it will consume Mercury, Venus, and possibly the Earth. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star's core. 2 What would happen if a neutron star was placed close to the earth? articles, published either in Randall Munroe's What If? That size implies a black hole can often swallow a neutron star whole. She covers climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical thought experiments. A real star type. The comet isn't the important part, the crane is. 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. A neutron star isn't as dense as a black hole . Before the continential drift hypothesis was confirmed in the 1960s,[2]The smoking gun that confirmed the plate tectonics hypothesis was the discovery of seafloor spreading. 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. Before publishing the first what if? As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. is based on his blog of the same name that answers unusual science questions from readers in a light-hearted way that is scientifically grounded. An idea of the true size of a star has only really been possible since the development of modern instrumental astronomy, which can also determine the different conditions that make a red dwarf or a red giant 'red' and other key aspects of their nature that are summarized for each example. These cookies ensure basic functionalities and security features of the website, anonymously. Ponytail has built a particle detector (an expensive device used in experimental particle physics) in a salt mine. So unless you stood right next to the spoon, you wouldnt notice. 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. So while you could lift a spoonful of Sun, you cant lift a spoonful of neutron star. If you built an icy waterfall from space, the water would arrive at the bottom as a river of superheated steam. X-ray: NASA/CXC/UNAM/Ioffe/D.Page, P. Shternin et al; Optical: NASA/STScI; Illustration: NASA/CXC/M. 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 added ice would cool the water down by only about a millionth of a degree. 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 Explanation []. We can use the Doppler effect to measure the orbital motion of a pulsar. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . It's hard to answer that, because the premise of the question is that the radius is steadily expanding while the density stays the samewhereas a black hole, the density increases. 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 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. They are responsible for, A real star type. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. 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. It's okay. Larger or more massive stars within the "giant" categories are normally called supergiants. At that speed, as long as you were in the right place at the right time, you could snatch it out of the air. On the other hand, if the atmosphere is also expanding, surface air pressure would rise. "Gamma And Neutrino Radiation Dose From Gamma Ray Bursts And Nearby Supernovae." (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.). . :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? Look at your handthere are about a trillion neutrinos from the Sun passing through it every second. what if? feed 2022 . DeathNoteRs 7 yr. ago. Far-Traveling Objects March 4, 2014.

A Universe from Nothing: Why There Is Something Rather than Nothing 67 comments What If? The neutron stars we can observe average about 1.8 million degrees Fahrenheit, compared to about 9,900 degrees Fahrenheit for the Sun. After five years, gravity would be 25% stronger. For the type of star, see Red dwarf." Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. How do you prevent jellyfish stings when swimming?
