xkcd what if neutron star

After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. [1] People have long suggested that it might be. That's why this is a neat question; supernovae are unimaginably huge and neutrinos are unimaginably insubstantial. Each one will cool the air a little bit. 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! The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. How long would it take for people to notice their weight gain if the mean radius of the world expanded by 1cm every second? Magical storks deliver babies, magical cranes deliver comets. It no longer burns hydrogen, helium . Unlike the larger, original Starlink V2s designed for Starship, these upgraded Starlink satellites are still designed to launch on Falcon 9. The aspect information provided for these 'star' types is based upon the respective mythologies. The CO2 released from the comet would raise the temperature of the Earth for centuries. Overwhelmingly Large Telescope xkcd comics i enjoy . 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. Surface gravity would only have gone up by 0.4%, rather than 1.2%, since surface gravity is proportional to radius. Sure, regular stars can create the basic elements: helium, carbon, neon, oxygen, silicon, and iron. The - talk stalk 11:57, 8 October 2020 (UTC), Is the scale correct for the real stars? There's been a lot of them, and they seem repetitive - no real new humor. Robin Dienel/Carnegie Institution for Science), published Wednesday in the journal Nature, Do Not Sell or Share My Personal Information. 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. The Earth is not, currently, expanding. However, you may visit "Cookie Settings" to provide a controlled consent. You also have the option to opt-out of these cookies. The Earth is not, currently, expanding. 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. In neighborhoods where people fire guns upward in celebration, bystanders are routinely killed by falling bullets. And by that point, you may find you've attracted some attention. This is the type of star that. Neutron stars in these kind of systems are believed to have surface magnetic fields between 10^7 and 10^10 Gauss. 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. 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. [5]Although letting a comet slowly decay on the surface would definitely be preferable to a high-speed impact, as any dinosaur from the end of the Cretaceous can tell you. 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 . and How To provides his best answers yet to the weirdest questions you never thought to ask. [1]This was confirmed by Mythbusters in episode 4 of Season 4. It does not store any personal data. It makes no sense that it is spherical, like a ball. Answer (1 of 22): Summary - This is fictional. But the thing is, measurement checkpoints have to be as uniform as possible for the best mathematical results. Inbox, #2, Weird (and Worrying) Questions from the What If? The heaviest neutron star ever detected is shredding its companion while spinning on its axis over 700 times per second. In true xkcd tradition, this is taken beyond reality. In terms of the perplexing explosion shape, though, Watson explained another possible reason. 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 . book series or on the blog. This is a list of What If? Most of our infrastructure would have collapsed. After five years, gravity would be 25% stronger. Neutron stars are incredibly dense objects about 10 miles (16 km) across. All rights reserved. Its like adding another mountain. 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). Copper is a fantastically good conductor of electricity, and much of the 20,000 amps could easily take a shortcut through the bullet. #HowTheUniverseWorksA neutron star is one of the most dangerous objects in the universe. What If chapters. 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. [Editor's note: This article was updated Feb. 23, 2022.]. 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. 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. Although there are some black holes with a mass of 70 times the sun). serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. 162.158.103.125 11:30, 17 September 2020 (UTC), Teal Sphinx? 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 That size implies a black hole can often swallow a neutron star whole. :) NiceGuy1 (talk) 03:54, 26 September 2021 (UTC), Let me know what you think. It's like the idiom "knock me over with a feather" or the phrase "football stadium filled to the brim with ants". This animation shows the size and scale of a neutron star over San Francisco. 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. Outer space is a lot higher up than Niagara Falls,[citation needed] so the plunge down into the atmosphere at the bottom of Earth's gravity well adds a lot more than 0.1 degrees worth of heat. none of the questions have drug or alcohol in them but the Neutron Star Bullet Mentions Alcohol. The nature of matter under these conditions is a decades-old unsolved problem. Thus, no matter your gun, youre not shooting a bullet around the Earth. would be around half a nanosievert, or 1/500th the dose from eating a banana.[7]xkcd.com/radiation. As the Earth grows, the Moon would, like all our satellites, gradually spiral inward. "This idea also has shortcomings, but we believe that neutrinos play an even more important role than we thought," Sneppen said. [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. book, articles were posted weekly.. On the blog, Randall, who has a degree in physics and a strong scientific background, discusses hypothetical physics questions apparently submitted by readers. The neutron star, known as PSR J0952-0607, was discovered in 2017 about . . Statistically, my first neutrino interaction probably happened somewhere around age 10. Its protons and electrons have fused together to create neutrons under the pressure of the collapse. Feb. 17, 2023 10:28 a.m. PT. Large comets can reach the ground intact and be vaporized on impact as their kinetic energy is converted to heat all at once. View our Privacy Policy. 4 (2002): 491-499. [14]Plummer, H. C., Note on the motion about an attracting centre of slowly increasing mass, Monthly Notices of the Royal Astronomical Society, Vol. Stretching a 40,000-kilometer line an extra 6.28 meters is pretty negligible. A giant star faces several possible fates when it dies in a supernova. "Supernovii" is discouraged. How long should I wait to text after being left on read? For the type of star, see Red dwarf." 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). Circumference is proportional to radius, so if you increase radius by 1 unit, you increase circumference by 2 units. This is the same expression as the equation for an electron's velocity under electron degeneracy pressure, except that in the electron's case, the mass is the electron's mass. She covers climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical thought experiments. I was raised Quaker; I've never held a gun, much less fired one. Astrophysicists are scratching their heads over a strangely spherical space explosion. At this point, the star is simply getting . "Sir, is this container under 3 ounces?" "Not sure, how much blood is there in a church mouse?" Reply . Lett., 38, L13304, doi:10.1029/2011GL047450. 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. It would just take a lot of patience. It premiered on August 11, 2021 and concluded on October 6, 2021. 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. The very central region of the star the core collapses, crushing together every proton and electron into a neutron. 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. [5]Lawrence Grybosky, Thermal Expansion and Contraction. That's why the phrase "lethal dose of neutrino radiation" sounds weirdit mixes scales in an incongruous way. Most buildings would probably be ok, although those anchored firmly into bedrock might start to behave unpredictably. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out!
