You get the point. 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. This crowd takes up an area the size of Rhode Island. By signing up you may also receive reader surveys and occasional special offers. Additionally, the star loses a lot of mass in the process and winds up only about 1.5 times the Sun's mass. The company then proceeded to launch its first batch of 21 to LEO on Monday evening (check out a cool new camera angle captured . What is the process that creates a neutron star? They are responsible for, A real star type. 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. A supernova radiates 10 times more neutrinos than there are particles, protons, neutrons and electrons in the sun. A tablespoon of a neutron star weights about 1 billion tons. A fatal radiation dose is about 4 sieverts. Copper is a fantastically good conductor of electricity, and much of the 20,000 amps could easily take a shortcut through the bullet. 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.

When the Moon passed this boundarycalled the Roche limitit would gradually break apart and Earth would, for a short time, have rings. At that speed, as long as you were in the right place at the right time, you could snatch it out of the air. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. [Editor's note: This article was updated Feb. 23, 2022.]. Well, if you hooked it up to a generator, you could use the slowly-descending comet to produce electricity. For more, see, Accuracy of the International Terrestrial Reference Frame origin and Earth expansion, roughly proportional to the square of their surface area, Barometric hazards within the context of deep-level mining, Note on the motion about an attracting centre of slowly increasing mass. Thank goodness xkcd creator Randall Munroe is here to help. Overwhelmingly Large Telescope xkcd comics i enjoy . As gravity increases, then air gets heavier. Previously, she was a science reporter with a start-up publication called The Academic Times, and before that, was an immunology researcher at Weill Cornell Medical Center in New York. The hardest part is sticking the landing. 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. 172.68.24.130 11:02, 30 November 2020 (UTC), No, not really. 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.

I had to turn it over in my head a few times after I heard it. Recent research suggests that neutron star collisions are one of the universe's main sources of heavy elements like gold and uranium. This theory was never very widespread,[3]It turns out it's kind of dumb. articles, published either in Randall Munroe's What If? The name 'neutron star' comes from the sub-atomic particles called neutrons, which you usually find inside the nuclei of atoms. [14]Plummer, H. C., Note on the motion about an attracting centre of slowly increasing mass, Monthly Notices of the Royal Astronomical Society, Vol. 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. If the comet were placed in the ocean,[3]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. The story icomes from a National Geographic video. 2: Additional Serious Scientific Answers to Absurd Hypothetical Questions is out! (Heavier stars produce stellar-mass black holes.) Despite all this, your scenario could fix global warming. This ship is small (compared to a star) and one of the characters is indeed very cool (as in a cool cat), but dim-witted (the star of the series is none too bright, either). \[ x=0.00001118\text{ parsecs}=2.3\text{ AU} \] 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 . Lett., 38, L13304, doi:10.1029/2011GL047450. 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? Filled with bonkers science, boundless curiosity, and Randall's signature stick-figure comics, What If? Eventually, they would have to break up, right? Health Physics 82, no. Statistically, my first neutrino interaction probably happened somewhere around age 10. That size implies a black hole can often swallow a neutron star whole. feed 2022 . Using the inverse-square law, we can calculate the radiation dose: Okay, if you insist. "Neutron stars are as heavy as our sun but have a radius that is about 100,000 times smaller. Toxicity aside, breathing dense air is difficult simply because it's heavy. and How To provides his best answers yet to the weirdest questions you never thought to ask. 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. The very central region of the star the core collapses, crushing together every proton and electron into a neutron. For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra. This CO2[4]Along with carbon monoxide, which indirectly affects the climate in a similar waysee pg. [2]Which would still be less than 1% of the ants in the world. When it comes to shape, though, neutron star collisions seem to be key. is a blog hosted on the xkcd.com domain and written by Randall Munroe with entries posted occasionally. At somewhere around 6 atmospheres, even ordinary air becomes toxic.[13]R.M. articles, published either in Randall Munroe's What If? No matter what, you do not want to find yourself near a neutron star. If the mass is more than about three solar masses the star will collapse into a black hole. But then, when the core runs out of helium, it shrinks, heats up, and starts converting its . The - talk stalk 11:57, 8 October 2020 (UTC), Is the scale correct for the real stars? 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. still have questions, and those questions are getting stranger. 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. That's why the phrase "lethal dose of neutrino radiation" sounds weirdit mixes scales in an incongruous way. "Supernovas" is also fine. It looks like it should be "1" or something, but it's not. The Earth is not, currently, expanding. https://www.explainxkcd.com/wiki/index.php?title=What_If_chapters&oldid=303706, Weird (and Worrying) Questions from the What If? Supernovae[4]"Supernovas" is also fine. 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. Filled with bonkers science, boundless curiosity, and Randalls signature stick-figure comics, What If? "Wu, X., X. Collilieux, Z. Altamimi, B. L. A. Vermeersen, R. S. Gross, and I.

It premiered on August 11, 2021 and concluded on October 6, 2021. 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 . 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. But what if we took just a spoonful of it and transpo. book series or on the blog. 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. Join Us in Tucson for Our Annual Public Star Party! After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. The #1 New York Timesbestselling author of What If? And indeed, it is by nine orders of magnitude. Everest. 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. While a normal black hole has the mass of 9.945e+30 (five times the sun. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. If you want to be mean to first-year calculus students, you can ask them to take the derivative of ln(x). The cause of the collapse would be the expanding ground below them, not the increased gravity. Inbox, #6, Weird (and Worrying) Questions from the What If?

This Neutron Star Explosion Was Perfect. Ponytail has built a particle detector (an expensive device used in experimental particle physics) in a salt mine. It's okay. The series is produced by Marvel Studios and was released on Disney+. Since you're moving steadily upward at 1 cm/s, you woudn't feel any kind of ongoing acceleration. 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.

Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions, The smoking gun that confirmed the plate tectonics hypothesis was the discovery of, Mass is proportional to radius cubed, and gravity is proportional to mass times inverse square of radius, so radius, 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. "Supernovii" is discouraged. [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. Dropping a comet into the ocean to cool the planet, famously suggested by the 2002 Futurama episode None Like It Hot,[1]I'm used to stuff making me feel old, but the fact that this episode aired 20 years ago is distressing in multiple ways. The event would likely shower us in so much high-energy cosmic radiation that it could spark a planetary mass extinction. They are extremely dense and no longer undergo nuclear fusion. 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. Neutron stars typically have a radius of 10 km / 6.2 mi and a mass of around 1.4 to 3.2 solar masses. Planning to ride a fire pole from the moon back to Earth? Surface gravity would only have gone up by 0.4%, rather than 1.2%, since surface gravity is proportional to radius. 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. 08.23.07. 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. Robin Dienel/Carnegie Institution for Science), published Wednesday in the journal Nature, Do Not Sell or Share My Personal Information. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star's core. 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. Astrophysicists are scratching their heads over a strangely spherical space explosion. When our sun enters this phase in a few billion years, it will consume Mercury, Venus, and possibly the Earth. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery . Serious Scientific Answers to Absurd Hypothetical Questions, Absurd Scientific Advice for Common Real-World Problems, More Serious Scientific Answers to Absurd Hypothetical Questions. At what point do these two unimaginable things cancel out to produce an effect on a human scale? Inbox, #3, Weird (and Worrying) Questions from the What If? This an illusion, of course; it's not possible to catch a bullet like that. Neutron stars have an important role in the universe. Is there any way to fire a gun so that the bullet flies through the air and can then be safely caught by hand? Munroe states on the comic's website that the name of the comic is not an initialism but "just a word with no phonetic pronunciation".. Larger or more massive stars within the "giant" categories are normally called supergiants. Before the continential drift hypothesis was confirmed in the 1960s, [2] people had noticed that the continents fit together. The mass sun is 400 times heavier than the mass of the moon. [8]See What-If #64. 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 normal star of that mass would be more than 1 million miles(1.6 million km) across. It does not store any personal data. This effect can be seen, dramatically, when a bullet is fired at ice. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. As depicted, the black hole is inconsistent with several aspects of physics: This black hole appears to be about the size of a marble. Typical properties are shown below. More active plate tectonics might be good for life. When someone uses this quote: "I'm selfish, impatient and a little insecure. Bottom line: Neutron stars are the collapsed cores of formerly massive stars that have been crushed to an extreme density by supernova explosions. Manifold Destiny: The One! Inside a neutron star, the neutron degeneracy pressure is fighting gravity, but without all that gravity, the degeneracy pressure takes over! How do I get rid of whiteheads on my nose naturally? Neutron stars are made in supernova explosions which are giant neutrino factories. The phrase "lethal dose of neutrino radiation" is a weird one. It's like the idiom "knock me over with a feather" or the phrase "football stadium filled to the brim with ants". 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. How do I move data from one tab to another in Excel? [5]Karam, P. Andrew. The "bullet catch" is a common magic trick in which a magician appears to catch a fired bullet in mid-flightoften between their teeth. You'd probably notice the weight gain, and you'd definitely notice the failure of roads, bridges, power lines, satellites, and undersea cables. 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 If? I was raised Quaker; I've never held a gun, much less fired one. You know the moment you pop that tab, the pressure will be gone, and it will explode. According to a 2016 study, supernovae occurring as close as 50 light-years from Earth could pose an imminent danger to Earths biospherehumans included.
