Neutron stars are phenomenally dense. It would just take a lot of patience. This animation shows the size and scale of a neutron star over San Francisco. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. The star starts fusing helium to carbon, like lower-mass stars. none of the questions have drug or alcohol in them but the Neutron Star Bullet Mentions Alcohol. Article title. After the initial jolt, one of the first effects you'd notice would be that your GPS would stop working. 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? Which would still be less than 1% of the ants in the world. A neutron star balances gravity with neutron degeneracy pressure. When it comes to shape, though, neutron star collisions seem to be key. (Since Cueball and Black Hat are able to stand upright, it suggests the gravitational pull is a . Necessary cookies are absolutely essential for the website to function properly. Large comets can reach the ground intact and be vaporized on impact as their kinetic energy is converted to heat all at once. 2.9K. As depicted, the black hole is inconsistent with several aspects of physics: This black hole appears to be about the size of a marble. 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. [2] So unless you stood right next to the spoon, you wouldnt notice. At this point, the star is simply getting . This is (currently) the main way global warming is raising the sea level. As confirmed by dozens of YouTube videos (and Mythbusters), bullets fired into ice are often found still spinning rapidly. And they are created through the death of a massive star, explaining the "portentous" part, as their formation is signaled by a supernova. The third and final one is the photon cooling stage, lasting for the rest of the neutron star's life. Some types of stars can vary in a wide range of sizes as well. 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. 0:52. Your pendulum clock would now be ahead by five days. This is a good thing to keep in mind if you buy a digital scale. [1] But under the right conditions, you could catch a bullet. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star's core. It makes no sense that it is spherical, like a ball. shooter is at sea level and catcher is up a mountain at the extreme range of the gun. After 100 years, we'd be experiencing over six gees of gravity. At the start of the scenario, the entire Earths population has been magically transported together into one place. Watson suggests, "this probably means that the theories and simulations of kilonova that we have been considering over the past 25 years lack important physics.". "No one expected the explosion to look like this. It wouldn't just cancel out the cooling effect of the iceover time, the comet's greenhouse effect would deliver as much heat as if you'd just let it slam into the planet and vaporize. e.g. A tablespoon of neutron star weighs more than 1 billion tons (900 billion kg) the weight of Mount Everest. Its like adding another mountain. This an illusion, of course; it's not possible to catch a bullet like that. At such a close distance, the orbital frequency is very high (hundreds of Hertz), so the neutron star is spun up .

Inbox, #11, Weird (and Worrying) Questions from the What If? Paint the Earth February 18, 2014. This effect can be seen, dramatically, when a bullet is fired at ice. 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. You'd probably notice the weight gain, and you'd definitely notice the failure of roads, bridges, power lines, satellites, and undersea cables. Sure, regular stars can create the basic elements: helium, carbon, neon, oxygen, silicon, and iron. They're like the baby brothers of black holes. Thank goodness xkcd creator Randall Munroe is here to help. What If? Order here! [11]Sasselov, Dimitar D.. 108.162.238.5 06:04, 19 September 2020 (UTC), 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 (pulsars, X-ray binaries, radio emissions, magnetic fields) when compared to live stars. "Knowing what the shape is, is crucial here, because if you have an object that is not spherical, it emits differently, depending on your sight angle. 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? If you succeeded, you might notice something odd: In addition to being hot, the bullet would be spinning. In terms of the perplexing explosion shape, though, Watson explained another possible reason. If you weighed 70 kg when the expansion started, you'd weigh 88 kg now. Sadly, we don't have the technology to build comet-lowering cranescertainly not in time to help mitigate climate change. Lett., 38, L13304, doi:10.1029/2011GL047450.

The title text is in the style of a Wikipedia page's hatnote / reference note. The satellites would stay in roughly the same orbits, but the delicate timing that the GPS system is based on would be completely ruined within hours. Inbox, #12, Lose Weight the Slow and Incredibly Difficult Way. A bullet fired straight up would eventually reach a maximum height. #HowTheUniverseWorksA neutron star is one of the most dangerous objects in the universe. When would the Earth eventually become a black hole? 125. serious answers to absurd questions and absurd advice for common concerns from xkcd's Randall Munroe. 08.23.07. feed 2022 . With a large enough supply of comets, we can keep the Earth nice and cool, as long as we make sure they're lowered slowly.

A larger planet would allow for more geologic activity, which is why some scientists think that exoplanets slightly larger than Earth ("super-Earths") could be more friendly to life than Earth-sized ones. Colliding neutron stars decapitate zombie theory of . 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. Order here! I was raised Quaker; I've never held a gun, much less fired one. The phrase "lethal dose of neutrino radiation" is a weird one. [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. Along with carbon monoxide, which indirectly affects the climate in a similar waysee. 3.262 light-years, or a little less than the distance from here to Alpha Centauri. That's why the phrase "lethal dose of neutrino radiation" sounds weirdit mixes scales in an incongruous way.

Death from Above. She covers climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical thought experiments. 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.

Inbox, #3, Weird (and Worrying) Questions from the What If? [4]Floor water. Neutron star matter is completely optically thick to photons. xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. For the type of star, see Red dwarf." Before publishing the first what if? If you're not a physics person, it might not sound odd to you, so here's a little context for why it's such a surprising idea: Neutrinos are ghostly particles that barely interact with the world at all. It premiered on August 11, 2021 and concluded on October 6, 2021. Toxicity aside, breathing dense air is difficult simply because it's heavy. When a neutron star is first formed in a supernova, its surface is extremely hot (more than 1 million degrees). :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? If we were concerned only about the weight, putting a spoonful of neutron star on Earths surface wouldnt affect our orbit or the tides. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. 2 is sure to be another instant classic adored by inquisitive readers of all ages. Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. Breathing would be difficult. [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. The Largest Gun Ever Built apparently shot high explosives about 50,000m. 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). Stretching a 40,000-kilometer line an extra 6.28 meters is pretty negligible. The very central region of the star the core collapses, crushing together every proton and electron into a neutron. Can a planet still function with a damaged moon? book series or on the blog. 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. A real star type. A sugar cube of neutron star material weighs as . 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. The Earth is not, currently, expanding. Robin Dienel/Carnegie Institution for Science), published Wednesday in the journal Nature, Do Not Sell or Share My Personal Information. They'd need to evacuate quickly; they'd have at most a few months before the station reentered the atmosphere and deorbited. Crops wouldn't stand up under their own weight. provide that scenario.
