Health Physics 82, no. Okay, so we just need thousands of comets, right? (Full text here.) e.g. 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. This would be very brief. 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 . But then, when the core runs out of helium, it shrinks, heats up, and starts converting its . Sunday, SpaceX shared photos of a stack of ~790 kg Starlink V2 "minis". Geologic activity would also accelerate. 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. In addition to dust and water, they contain a small amount of CO2, which would be released into the atmosphere as the comet melted. Large comets can reach the ground intact and be vaporized on impact as their kinetic energy is converted to heat all at once. 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. "Supernovii" is discouraged. More details.. 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/ "Sir, is this container under 3 ounces?" "Not sure, how much blood is there in a church mouse?" Reply . But what if we took just a spoonful of it and transported it to Earth? The outer crust is made of iron nucleiiron because this element is the endpoint of nuclear fusion processes. 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. Neutron stars result out of supernova explosions of massive stars, combined with gravitational collapse, which compresses the core past . The neutron star, a pulsar designated PSR J0952-0607, is thus the densest object within sight of Earth. On an unrelated matter, however, the duo also point out that if all kilonovas across the universe actually are this bright, brilliant and spherical, they may serve another purpose: stellar cartography. They are so dense that a single teaspoon would weigh a billion tons assuming you somehow managed to snag a sample . Neutron stars are made in supernova explosions which are giant neutrino factories. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . Neutron star matter is completely optically thick to photons. In fact, neutrinos are so shadowy that the entire Earth is transparent to them; nearly all of the Sun's neutrino flood goes straight through it unaffected. Enforced by Radar March 11, 2014. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star's core. 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. 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. The mass of the sun is 1.989 10 30 kg while the mass of the moon is 7,348 * 10 22 kg. New York: Basic Books, 2012. This cookie is set by GDPR Cookie Consent plugin.

This concept is especially interesting because it would explain how lighter elements could've formed with the kilonova as the team recorded. But what if we took just a spoonful of it and transpo. Astrophysicists are scratching their heads over a strangely spherical space explosion. This is a good thing to keep in mind if you buy a digital scale. The aspect information provided for these 'star' types is based upon the respective mythologies. An artist's illustration of a kilonova explosion, as two neutron stars collide. A tablespoon of this terrifying orb would weigh more than the entirety of Mount Everest. Answer (1 of 22): Summary - This is fictional. His stick-figure drawings about science, technology, language, and love have an enormous, dedicated following, as do his deeply researched answers to his fans' strangest questions. 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. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. Neutron stars are the densest things besides black holes. Article title. is a blog hosted on the xkcd.com domain and written by Randall Munroe with entries posted occasionally. View our Privacy Policy. Generally, it turns into heat. 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. When she's not at her desk, she's trying (and failing) to raise her online chess rating. In the other scenario, we'd be ok for a little while longer. After 40 years, Earth's surface gravity would have tripled. NICER is a two-in-one mission. [9]Although I wouldn't trust the elevators. Typical properties are shown below. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. Supernovae[4]"Supernovas" is also fine. There are no purely vertical cliffs that are that tall, so you'd need to fire the bullet at an angle, and it would have significant sideways speed at the top of its arc. This is a list of What If? Is political science a good major for law? I was raised Quaker; I've never held a gun, much less fired one. We do not sell, rent or trade our email lists. After a year, gravity would be 5% stronger.

This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. [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. A tablespoon of neutron star weighs more than 1 billion tons (900 billion kg) the weight of Mount Everest. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! Before publishing the first what if? After 100 years, we'd be experiencing over six gees of gravity. After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. Everest would no longer be in the "death zone". His 2014 book What If? 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. These cookies track visitors across websites and collect information to provide customized ads. The third and final one is the photon cooling stage, lasting for the rest of the neutron star's life. When would the Earth eventually become a black hole? It premiered on August 11, 2021 and concluded on October 6, 2021. 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. 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. Enter the Space & Beyond Box Photo Contest! Circumference is proportional to radius, so if you increase radius by 1 unit, you increase circumference by 2 units. 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. Want to know what would happen if you rode a helicopter blade, built a billion-story building, made a lava lamp out of lava, or jumped on a geyser as it erupted? 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. would be around half a nanosievert, or 1/500th the dose from eating a banana.[7]xkcd.com/radiation. Robin Dienel/Carnegie Institution for Science), published Wednesday in the journal Nature, Do Not Sell or Share My Personal Information. \[ 0.5\text{ nanosieverts} \times\left ( \frac{1\text{ parsec}}{x}\right )^2 = 5\text{ sieverts} \] No matter what, you do not want to find yourself near a neutron star. I was raised, Don't do this. Rocket Golf February 25, 2014. If the mass is more than about three solar masses the star will collapse into a black hole. Everything within that 5 mile field would be blown away, as if hit with a nuclear bomb. Gravity varies by this much between different cities already. When it comes to shape, though, neutron star collisions seem to be key. While a normal black hole has the mass of 9.945e+30 (five times the sun. After the first day, the Earth would have expanded by 864 meters. 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). The second is this neutrino cooling stage, lasting to ~10 5 years. Only small insects (and sea animals) would be physically able to move around. Too Perfect. 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. What if a tablespoonful of a neutron star was brought to Earth. This cookie is set by GDPR Cookie Consent plugin.

Red dwarf: 0.09-0.5 R; 0.07-0.3 M, 1500-4000 K, 0.00001-0.05 L. 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. 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. Franz and P.C. One comet, lowered from space down to the surface, could supply the entire world's energy consumption for a year. 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. Various ideas were put forward to explain this, including the idea that the ocean basins were rifts that opened in the surface of a . 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.

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. Gamma And Neutrino Radiation Dose From Gamma Ray Bursts And Nearby Supernovae. A tablespoon of the Sun, depending on where you scoop, would weigh about 5 pounds (2 kilograms) the weight of an old laptop. -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. 125. Less often if you're a child, since you have fewer atoms to be hit. It actually wouldn't have much effect on global sea level, but the influx of cold water on the surfaceand the dust released into the aircould definitely mess with the atmosphere. 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. A sugar cube of neutron star material weighs as . Far-Traveling Objects March 4, 2014. You'd probably notice the weight gain, and you'd definitely notice the failure of roads, bridges, power lines, satellites, and undersea cables. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. : Serious Scientific Answers to Absurd Hypothetical Questions Gravity would take a long time to increase. 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. Monisha Ravisetti is a science writer at CNET. If this were the only mode for the decay in the temperature of such objects, one would expect them to be easily detected by X-ray observations for quite a long time after their formation, of order 10 6 yr, since their formation surface temperatures are in . [1] People have long suggested that it might be. The release of magnetic energy could cause the matter in the explosion to be distributed more spherically. Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. If you succeeded, you might notice something odd: In addition to being hot, the bullet would be spinning. A bullet fired straight up would eventually reach a maximum height. Necessary cookies are absolutely essential for the website to function properly. As gravity increases, then air gets heavier.

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. The comic's tagline describes it as "a webcomic of romance, sarcasm, math, and language". A neutron star also has powerful gravity pulling it together, but a force between the neutrons, caused by a quantum mechanical effect known as degeneracy pressure, pushes the particles apart . 2.9K. [11]Sasselov, Dimitar D.. Toxicity aside, breathing dense air is difficult simply because it's heavy. 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. Join Us in Tucson for Our Annual Public Star Party! Inbox, #1, Weird (and Worrying) Questions from the What If? But since that air is spread out over a larger area, the overall effect would be decreasing air pressure. Soda Sequestration March 18, 2014. 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. How long should I wait to text after being left on read? 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. Neutron stars typically have a radius of 10 km / 6.2 mi and a mass of around 1.4 to 3.2 solar masses. 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. (, An invention of Randall's, and a reference to the elves of. ''Your stupid!''. [1]Less often if you're a child, since you have fewer atoms to be hit. 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. At this point, the star is simply getting . [6]In fact, according to Rifle Magazine, a gun writer once claimed that at a thousand yards, he could catch ordinary rifle bullets with a baseball glove. How do I minimise waste on a flight? One is that dropping things from space creates heat. You'd have to grab the bullet firmly; otherwise, it might jump out of your hand. Inbox, #10, Weird (and Worrying) Questions from the What If? Its like adding another mountain. What If chapters. 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. 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. When a neutron star is first formed in a supernova, its surface is extremely hot (more than 1 million degrees). When wateror anything elsefalls, it gains kinetic energy. For more, see this chapter and this article. 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. 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? While you might not notice the increased gravity just yet, you'd notice the expansion. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! 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. Blue giant: 2-400 R; 2-300 M, 8000-60000 K, 15-10000000 L. The detonation of a hydrogen bomb pressed against your eyeball?

No. Despite all this, your scenario could fix global warming. people had noticed that the continents fit together. Death from Above. A tiny piece of a comet would float for a short time until it became waterlogged, melted, and broke apart. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! Neutron stars tend to be formed at about 1.4 solar masses, but more material can fall onto them after that. Concrete expands and contracts by more than that every day. This is probably a case of artistic license. This an illusion, of course; it's not possible to catch a bullet like that. 718-719 of the IPCC WG1 AR5 report for more. How close would you have to be to a supernova to get a lethal dose of neutrino radiation? Inbox, #4, Weird (and Worrying) Questions from the What If? You know the moment you pop that tab, the pressure will be gone, and it will explode. This means that the accreting gas can spiral very close to the neutron star before it is grabbed by the magnetic field. Not only would we be unable to move around to find food, but our hearts would be unable to pump blood to our brains. 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). 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 event would likely shower us in so much high-energy cosmic radiation that it could spark a planetary mass extinction.
