what happens if you go straight up in space

This is the singularity. Hawking said in 2016: "If you feel you are in a black hole, don’t give up. (Ah, yes:) *a table is always good to hide under*, life is too short to drink instant coffee. There are several definitions, yours as good as anyone else I've seen Alan. You can see this law when you blow up a balloon and let it go without tying it. Edit - Spelling and grammar. As one falls through the … The pressure from the water would push in on the person’s body, causing any space … You'd have to accelerate westward in order to become "stationary", and such acceleration would require more energy than simply flying there normally on an airplane. You might not be able to speak to family or friends. - Shawntay Muskegon,MI,U.S.A. Only use public transport if you have no other option. Surprisingly, you probably wouldn’t explode. Defining up will help you understand how meaningless your question is. "But what would happen if you just go straight up, let's say 10,000 kilometers?". (3) The water pressure is very high. The Kármán line, which is commonly represented as the boundary between Earth's atmosphere and outer space, is at an altitude roughly 62 miles above sea level. racetracks are ovals, not squares or rectangles, for a reason. It’s kind of like when we look at a globe, she explains. The deeper you go, the heavier the water above you and so the greater the pressure on your body. (ie you can go "straight" in a circle around a star). And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? report. The ISS, for example, goes at 4860 m/s. It depends on the direction you want to travel. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. Furthermore, let's consider what happens if two objects start off along the same path in space-time. Presumably, the track of a vehicle that does not experience lateral acceleration. Even then, your orbit will skim the top of the atmosphere, where the friction will cause a deorbit in a few days. If you land on a career space, pay the person with the matching Career Card or if no one has it, pay the bank (if you own it you don't need to do anything). Keep all Life Tiles Life-side-up in front of you; looking at the values on the Life Tiles is against the rules. When you go to write a file, it writes that file’s data into the empty blocks. Well, there are some other definitions too. And sideways speed is what you need to get into orbit around Earth, without crashing back down. "On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel).". That’s the reason why space shuttle launches use large external hydrogen tanks and fuel boosters, as they want to achieve a huge amount of speed in a matter of seconds . What happens if I get sent to prison? And what is a 'straight line' in SpaceTime? The judge or magistrate will tell you how long you will spend in prison. In a hypertorus model of the Universe, motion in a straight line will return you to your original location. Join Yahoo Answers and get 100 points today. Serious side effects are rare and happen to less than 1 in 1,000 people. Skin is almost completely gas-tight and strong enough to withstand a pressure differential of well over one atmosphere. i now u probly could not do it, but if you could what would happen would you go on for ever or would you hit somthing like a wall lol or would you keep goin round and … They do it this way to conserve fuel; because going "straight up" to that altitude requires a longer burn, and more fuel - then using the Hohmann transfer orbit. If you fire a gun into the air, the bullet will travel up to a mile high (depending on the angle of the shot and the power of the gun). Or a geodesic, or a world line in Relativity. If you have one or more of these symptoms, you must self-isolate straight away for 10 days – or longer if you still have symptoms other than cough or loss of sense of smell/taste. depends, are you accelerating or maintaining velocity forever, or do you burn for a limited time and then coast? That is why a space elevator is such a great idea, except the mechanics becomes a problem. If you are in space and the earth is the nearest astronomical object, you fall towards earth. Orbiting is a process where the object in orbit is always falling toward earth, but has enough horizontal speed to avoid hitting it. And, it must come out in the direction opposite of the way we want the rocket to go. well, sorry, I was wrong. You should be able to convince yourself that the only way this can happen is if the two objects start off in the same direction and at the same speed. https://en.wikipedia.org/wiki/Fermat%27s_principle, Quote from: yor_on on 01/11/2020 20:50:21, Is "Space" distinct from "nothingness"? If it didn’t do that and continued to go straight up, it would eventually reach a point where its fuel would run out and, most likely, it would end up plummeting back to Earth like a stone. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. When you shoot a gun in space, things can get pretty weird. The air gets thinner and thinner the higher you go, until there's hardly any air at all. The Bible says there is an interval between death and receiving the new body in Christ, yet you say people in Christ put on the new body immediately up their "first step in Heaven." Is there water on other planets in our solar system? Just in case things get ugly and the world erupts into a real Star Wars, yes, it is possible to shoot a gun in space. The air rushes out of the mouth of the balloon. A scenario often presented to introductory physics classes is that of a \"gravity tunnel\" a tube drilled from one side of the Earth to the other through the planet's center. share. And if you have a news tip, correction or comment, let us know at: community@space.com. you can also express it as it chooses the path that takes the shortest time, they are not exactly the same, although, ah well. So you want to get out of the lower atmosphere (the first 60 km or so) as soon as possible. As a pilot of a space shuttle though, you want to get out of the atmosphere as soon as practically possible, and for that, you need a very high velocity. "Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit.". The problem is that you're moving along with the earth. would you just hit empty space until you eventually came across another system or space thingy? But fortunately, that loss of 100 watts of heat isn't all that much compared to the sheer mass of your body. The first indication something’s up is you are calling and sending text messages, but you get no response. Though not the longest stint in space, it is the longest anyone has spent on board the International Space Station (ISS) and the best opportunity NASA has had to study what happens … ... once they get above most of the atmosphere, and additional speed does not cause too much more friction. This law also tells us how to build a powerful rocket. Air resistance limits its speed, but bullets are designed to be fairly aerodynamic , so the speed is still quite lethal if the bullet happens to hit someone. Is a stationary object in space really stationary? What would happen to an unprotected person at the bottom of the ocean or in outer space? This website uses cookies to improve your experience while you navigate through the website. (and the Vacuum). It seems to take so much fuel to go straight up, and in my mind I can't see to get my head around why they don't take off like a plane and go up gradually like that. There is NO "straight up" or "straight down" in space. The balloon flies the other way. So it seemed like a good time to revisit this topic, and clear up a few misconceptions: Misconception No. In space, no one can hear you scream.Oooooh! ©The Naked Scientists® 2000–2017 | The Naked Scientists® and Naked Science® are registered trademarks created by Dr Chris Smith. What happens to those ones 'non existing' in a outcome? If you went "straight" up, you would still have to turn at some point in order to gain that needed horizontal speed. https://en.wikipedia.org/wiki/Space_elevator. Gravity is only about 10% weaker at 300km (which is well above the bulk of the atmosphere) than it … But to keep going upwards would be the exact same thing sameat going off in everyother direction. Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit. If you are wearing a face mask, you notice that as you dive deeper, the mask presses harder and harder on your face. This is due to gravity. If you are in space and the earth is the nearest astronomical object, you fall towards earth. "What goes up, must come down," is an old saying that remains true for any object thrown or fired from Earth's surface that fails to escape into space. ", "Wouldn't that also costs much less fuel since space is a vacuum?". Several times I have seen it pointed out that the companies that are building craft to "go to space" with people from high altitude launch or recoverable rockets (not SpaceX) have a much easier problem to solve because they do not have to get the extra 10,000 miles per hour or more needed to orbit - they are just giving their riders some weighlessness. Re: What happens if you go straight in space? But if they would, somewhere exist, Fermat's principle can't be true, am I right? So the relativistic question is whether the occupants of a vessel following a beam of light, which describes a geodesic in spacetime, would experience any acceleration perpendicular to the axis of their ship. If you fly "straight up into space", you'll still be moving very quickly from west to east. The solution to this problem depends on the strength of Earth's gravitational pull, which in turn is based on its mass. Join our Space Forums to keep talking space on the latest missions, night sky and more! If you simply go straight up to outer space (say 300 km above Earth's surface), gravity will pull you right back down, even if you've left the atmosphere, and you'll crash back into the Earth. Once it reaches its apogee, the bullet will fall. If you fire a gun into the air, the bullet will travel up to a mile high (depending on the angle of the shot and the power of the gun). The rocket needs to shoot out a lot of material. You’ll swell up pretty bad, perhaps even up to twice your normal size, but you won’t explode as your skin is very stretchy. There are many reasons this might be happening, but a blocked number is one possibility. But they climb straight up for part of the way, so that the atmosphere is much less dense. You would still have to life all the fuel out of the gravity well and the whole path is planned to get the rocket above the bulk of the thick atmosphere while at slower before bending over and accelerating with smaller/fewer engines. But, since you seem to be looking for a more specific answer than that, let’s take it one at a time. How do you think about the answers? If you see me running, try to keep up.". Your blood will also not boil. It must come out at a high speed. The extremely smart people who are part of the space program have worked out the best, fastest, least costly way yo get into space. The concepts of "up" and "down" only apply in the gravity well of a moon, planet, or star. Career Spaces are extra opportunities to make some money from other players. If you want to cross the Atlantic Ocean, you go east. if you go straight up you are still moving in an arc because the planet is spinning. contestant, Why some find the second gentleman role 'threatening', At least 3 dead as explosion rips through building in Madrid, Pence's farewell message contains a glaring omission. Also, your ears start feeling the pressure even at 2 or 3 meters (5 or 10 feet) below the surface. Going straight up would lose you the 1000 mph or so of launching to the east closer to the equator. So wouldn’t it make more sense if they went straight up in a line, rather than following a parabolic path? If you insist, however, on going straight up in the sky and hovering, then the first thing you’ll need is an airplane that can hover for a long time (‘hovering’ is not what airplanes are built for, FYI). In other words, it's nearly a vacuum up there.Even the lowest Earth-orbiting spacecraft orbit at around 200 kilometers (125 miles) above Earth's surface, far above the thick air we are accustomed to … It still sounds like I’m making excuses. You can’t breath at the bottom of the ocean. Still have questions? While it's *possible* to do what you're saying - it's more economical not to.... and, companies sending up satellites worth hundreds of millions of dollars are definitely looking at ways to save money. sounds stupid i know, but when i think about the solar system i see the planets in a row out from the sun. If you want to fly over the Pacific Ocean, you go west. Do I need to introduce a many worlds scenario in where they too exist? So, consider satellites that go into Geo-sync orbit... that's about 23,600 miles in space. (Image credit: NASA (astronaut image)) Shooting giants from the hip. If you simply go straight up to outer space (say 300 km above Earth's surface), gravity will pull you right back down, even if you've left the atmosphere, and you'll crash back into the Earth. It seems to take so much fuel to go straight up, and in my mind I can't see to get my head around why they don't take off like a plane and go up gradually like that. Any slower and you will fall back to your starting point. Just in case things get ugly and the world erupts into a real Star Wars, yes, it is possible to shoot a gun in space. Down is not towards the earth's South Pole and up is not towards the earth's North Pole. If you are trying to get to Japan from the U.S., you can see it is both east and west of the U.S. When you arrive in England, go straight to the place you’re staying to self-isolate. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds. Page created in 0.22 seconds with 78 queries. Over time, calcium normally stored in the bones is broken down and released into the bloodstream. Air resistance limits its speed, but bullets are designed to be fairly aerodynamic, so the speed is still quite lethal if the bullet happens to hit someone. If you simply launched straight up, you'd fall straight down, it's the speed that makes the difference. Get your answers by asking now. Calling it 'models' or 'interpretations', but it doesn't change the facts. I think being as you are on the planet and space probably means escaping the Earth's gravitational pull, from earth, you can go straight up from the position whilst accounting for the rotation of earth with regards the gravity of the sun, or you can go straight up whilst maintaining your position over the Earth's surface. • The more meaningful answer is: If we account for gravitational curvature of the spacetime in the universe, then a straight line can be a stable orbit about a massive body. that happens sometime. everything in orbit eventually gets closer and falls in due to friction unless it gets propelled every now and then to make up for the drag. Look out into the depths of the universe and you’ll see galaxies floating edge-on, face-on and at … orbit is a fall but moving laterally fast enough that you never fall in. If you have enough fuel and reach 24,000 mph you will escape from earth. If we assume that a wavefront 'sweeps' all possible paths. But the problem is that in the lower atmosphere, going really fast causes a lot of air friction. This isn’t a mistake… you will see the exact same thing in every other picture and video of a rocket launch. If you went straight up, you wouldn't have any sideways speed. The pressure you feel on your body is due to the weight of the water above you. If you are not born again, then you will have no opportunity to go to heaven when you die but will the very next moment be in torment. In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. If the Universe is expanding, does this mean that space is expanding? We Know The Extent Of The Sun, What Is The Extent Of Space Time? If I want to be cynical, which I most probably is, I would say that without a interpretation statistics are meaningless. At the same time, many bones that aid in movement are no longer subjected to the same stresses that they are subjected to on Earth. But for straight up, you’d need about 30 km/s, meaning more fuel, and compromises to your payload. Does the engine of a space shuttle produce sound as it orbits earth? But what would happen if you just go straight up, let's say 10,000 kilometers? Astronomers love to remind us that there’s no up or down in space. If you are sentenced to prison time you will have to go straight to prison from court. Is it possible for humans to live in another planet? I said ' light always choosing the shortest path between two points'. There is no up and down in space. Then, you would need to burn a huge amount of fuel in order to stay stationary and resist the strong winds slapping against the plane at that altitude. In a way it explains everything Alan. And it's better to do this as soon as possible, so you don't have to carry extra fuel to go straight up. According to the video, poor posture inflicts extra wear and tear on joints and ligaments, increases the likelihood of accidents, makes organs like your lungs less efficient --hunching over can affect your lung capacity by as much as 30 percent -- and is … Pretty scary, kids. That is certainly <>, but is foolish. If you drove straight up you would arrive in space in just over an hour. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. You will wait in torment, like the rich man is still waiting today. Once it reaches its apogee, the bullet will fall. . The escape velocity there is lower, but still significant. Rockets are supposed to go into space, right? It's better to have all your speed sideways, parallel to the Earth's surface, so that your orbit is as circular as possible. We can get into a rocketship and go in the "up" direction (a direction, I remind you, that doesn't exist for our 2-dimensional ant friends) fly all around the earth, and see that it's round directly. Unguided toy rockets do this. As there is no huge gravity pulling us like Earth there is no up or down. No big deal. Information presented on this website is the opinion of the individual contributors and does not reflect the general views of the administrators, editors, moderators, sponsors, Cambridge University or the public at large. The Bible revealed the nature of time long before Stephen Hawking and other physicists started thinking about it. The thrust needed to launch the space shuttle is provided by two solid rockets and three space shuttle engines, all of which operate during lift-off.According to NASA, the thrust provided by the two solid boosters is 6.6 million pounds, whereas the three engines of the shuttle provide almost 1.2 million pounds’ worth thrust.This means the total thrust during a launch is 7.8 million pounds! We can get into a rocketship and go in the "up" direction (a direction, I remind you, that doesn't exist for our 2-dimensional ant friends) fly all around the earth, and see that it's round directly. This, however does not account for the motions of that star with respect to other things. This means if you could drive straight up going 60mph you would arrive in outer space in just over an hour's time. Discussion. 10 The Vacuum Of Space First things first—if the exterior of your spaceship is compromised (punctured by a whizzing asteroid perhaps) the interior will rapidly depressurize, and you will be sucked out into the vacuum of space. Is it true that Uranus contains a water ocean beneath the visible part? A: Shawntay - Well, the rough summary in either case is that the person in question would be very dead, very fast, in a very unpleasant manner. As you go deeper into the black hole, space becomes ever more curvy until, at the centre, it becomes infinitely curved. Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. Personally I look at it as a straight line is the one expending no energy, but that's when I naively apply it on what I get from reading about SpaceTime. Mental Floss defines "outer space" as "the universe beyond Earth's atmosphere and between planets and other stellar bodies," and reveals that sound travels via mechanical waves transmitted through one medium or another — liquid, solid, or gas, like normal Earth air, of which there is a notable lack in outer space. Started by SeanyBoard Physics, Astronomy & Cosmology, Started by geordiefBoard Physics, Astronomy & Cosmology, Started by TitanscapeBoard Physics, Astronomy & Cosmology, Started by EthosBoard Physics, Astronomy & Cosmology, Started by chintanBoard Physics, Astronomy & Cosmology. On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel). Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. When an SSD has little free space, it has a lot of partially filled blocks. save. They first go into low-earth orbit, then fire an engine to travel up to 23,600 miles in an elliptical orbit, then fire the engine again to *maintain* their 23,600 mile altitude. So if we agree that space-time, and not space, is the proper arena in which to consider the question, then we can understand why the ball and the bullet don't wind up in the same place at the end of their trip. What is that thing in astronomy that night stars in the sky are dead, gone, don't exist etc. You can sign in to vote the answer. if you go straight without moving with the orbit of the planet, you cant get into orbit because you must be traveling laterally in order to stay in orbit... else you just fall back down.
