Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. In space there's nothing to insulate you, so eventually you'll freeze to death. The extremely smart people who are part of the space program have worked out the best, fastest, least costly way yo get into space. And if you have a news tip, correction or comment, let us know at: community@space.com. Even on Earth's surface, each square inch of your body experiences 14.7 pounds of pressure due to the weight of the atmosphere above you. unless the universe is contracting (or will contract in the future) then this is false. (3) The water pressure is very high. (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. Surprisingly, you probably wouldn’t explode. Career Spaces are extra opportunities to make some money from other players. Defining up will help you understand how meaningless your question is. If we assume that a wavefront 'sweeps' all possible paths. 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. orbit is a fall but moving laterally fast enough that you never fall in. What happens if you go straight in space? Down is not towards the earth's South Pole and up is not towards the earth's North Pole. There are many reasons this might be happening, but a blocked number is one possibility. The balloon flies the other way. And sideways speed is what you need to get into orbit around Earth, without crashing back down. if you go straight up you are still moving in an arc because the planet is spinning. 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 … In a nutshell, a rocket must curve its trajectory post-launch, if it wants to enter the Earth’s orbit. But if they would, somewhere exist, Fermat's principle can't be true, am I right? 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. 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. If you drove straight up you would arrive in space in just over an hour. 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). We Know The Extent Of The Sun, What Is The Extent Of Space Time? The air rushes out of the mouth of the balloon. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. Pretty scary, kids. "What happens if you go STRAIGHT up into space?". On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel). There are several definitions, yours as good as anyone else I've seen Alan. Basically, the rocket only goes straight up for a short period of time, then turns slightly off to allow Gravity to actually work for the rocket. Once it reaches its apogee, the bullet will fall. 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." So wouldn’t it make more sense if they went straight up in a line, rather than following a parabolic path? Astronomers love to remind us that there’s no up or down in space. But, since you seem to be looking for a more specific answer than that, let’s take it one at a time. In space, the amount of weight that bones must support is reduced to almost zero. "Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit.". Orbiting is a process where the object in orbit is always falling toward earth, but has enough horizontal speed to avoid hitting it. Orbiting is a process where the object in orbit is always falling toward earth, but has enough horizontal speed to avoid hitting it. https://en.wikipedia.org/wiki/Space_elevator. you can also express it as it chooses the path that takes the shortest time, they are not exactly the same, although, ah well. Furthermore, let's consider what happens if two objects start off along the same path in space-time. I can't decide on that one. 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. • 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. ... once they get above most of the atmosphere, and additional speed does not cause too much more friction. And it's better to do this as soon as possible, so you don't have to carry extra fuel to go straight up. If you are in space and the earth is the nearest astronomical object, you fall towards earth. The concepts of "up" and "down" only apply in the gravity well of a moon, planet, or star. 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. 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. When you shoot a gun in space, things can get pretty weird. Look out into the depths of the universe and you’ll see galaxies floating edge-on, face-on and at … But for straight up, you’d need about 30 km/s, meaning more fuel, and compromises to your payload. 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. 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! Join our Space Forums to keep talking space on the latest missions, night sky and more! 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. As you go deeper into the black hole, space becomes ever more curvy until, at the centre, it becomes infinitely curved. In space, no one can hear you scream.Oooooh! Your blood will also not boil. When you go to write a file, it will have to read the partially filled block into its cache, modify the partially-filled block with the new data, and then write it back to the hard drive. Edit - Spelling and grammar. It must come out at a high speed. How do you think about the answers? You can see this law when you blow up a balloon and let it go without tying it. This means if you could drive straight up going 60mph you would arrive in outer space in just over an hour's time. If you went "straight" up, you would still have to turn at some point in order to gain that needed horizontal speed. 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. Is a stationary object in space really stationary? In a hypertorus model of the Universe, motion in a straight line will return you to your original location. You will wait in torment, like the rich man is still waiting today. That is certainly <>, but is foolish. In a flat space the shortest path between two points. For reasons of repetitive antagonism, this user is currently not responding to messages from; "BOMB DISPOSAL EXPERT. what happens if instead of flying towards mars or another planet you just went straight up. what would happen if you went straight up to space and kept going up and up and dident stop? Down is not towards the earth's South Pole and up is not towards the earth's North Pole. So it seemed like a good time to revisit this topic, and clear up a few misconceptions: Misconception No. When you arrive in England, go straight to the place you’re staying to self-isolate. But to keep going upwards would be the exact same thing sameat going off in everyother direction. It depends on the direction you want to travel. Does the engine of a space shuttle produce sound as it orbits earth? If you are wearing a face mask, you notice that as you dive deeper, the mask presses harder and harder on your face. Keep all Life Tiles Life-side-up in front of you; looking at the values on the Life Tiles is against the rules. Once it reaches its apogee, the bullet will fall. Page created in 0.22 seconds with 78 queries. Sure. 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 you went straight up, you wouldn't have any sideways speed. Serious side effects are rare and happen to less than 1 in 1,000 people. The rocket runs out of fuel and you fall back to EARTH. The first indication something’s up is you are calling and sending text messages, but you get no response. 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 . The ISS, for example, goes at 4860 m/s. This website uses cookies to improve your experience while you navigate through the website. The deeper you go, the heavier the water above you and so the greater the pressure on your body. 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. The Bible revealed the nature of time long before Stephen Hawking and other physicists started thinking about it. 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. (Ah, yes:) *a table is always good to hide under*, life is too short to drink instant coffee. what happens when you go up or down. 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. Is it possible for humans to live in another planet? That is not right. If you are in space and the earth is the nearest astronomical object, you fall towards earth. You also wouldn’t instantly freeze. That is why a space elevator is such a great idea, except the mechanics becomes a problem. Is there water on other planets in our solar system? 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. Also, your ears start feeling the pressure even at 2 or 3 meters (5 or 10 feet) below the surface. And here's something funny about it. depends, are you accelerating or maintaining velocity forever, or do you burn for a limited time and then coast? I said ' light always choosing the shortest path between two points'. But they climb straight up for part of the way, so that the atmosphere is much less dense. sounds stupid i know, but when i think about the solar system i see the planets in a row out from the sun. 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 … And, it must come out in the direction opposite of the way we want the rocket to go. You can sign in to vote the answer. Going straight up would lose you the 1000 mph or so of launching to the east closer to the equator. Rockets are supposed to go into space, right? What happens to those ones 'non existing' in a outcome? Only use public transport if you have no other option. 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. 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. 8 comments. Re: What happens if you go straight in space? that happens sometime. But the reality of a human exposed to the vacuum of space may be weirder and more bizarre than you ever imagined. Still have questions? If you were to lift off from the the North Pole and kept going up then one could say that they did go straight up in relation to he North pole and you could keep going if you were to say that. Even then, your orbit will skim the top of the atmosphere, where the friction will cause a deorbit in a few days. 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. If you could dive down to the center of Earth, the pressure on your body would be about 3.5 million times as great! however, if the universe is contracting then you will eventually be sucked into nothing and so yeah, youll end up where you started. But what would happen if you just go straight up, let's say 10,000 kilometers? 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 … Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? save. So, consider satellites that go into Geo-sync orbit... that's about 23,600 miles in space. This isn’t a mistake… you will see the exact same thing in every other picture and video of a rocket launch. 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. If the Universe is expanding, does this mean that space is expanding? 0 Members and 1 Guest are viewing this topic. Get your answers by asking now. Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit. The air gets thinner and thinner the higher you go, until there's hardly any air at all. Do I need to introduce a many worlds scenario in where they too exist? 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. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. You can’t breath at the bottom of the ocean. 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. "On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel).". 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. No big deal. In a way it explains everything Alan. At an altitude of 10,000 km, you need a speed sideways of 3158 m/second to have an orbit, otherwise your path will intersect the Earth on the first orbit. If you want to cross the Atlantic Ocean, you go east. Friends or family can arrange to visit you when you get to prison. Is it true that Uranus contains a water ocean beneath the visible part? But the problem is that in the lower atmosphere, going really fast causes a lot of air friction. If you fly "straight up into space", you'll still be moving very quickly from west to east. Over time, calcium normally stored in the bones is broken down and released into the bloodstream. It's better to have all your speed sideways, parallel to the Earth's surface, so that your orbit is as circular as possible. In the former case, you’ll eventually accelerate to a large portion of the speed of light (you’ll never reach it, because you have mass), and assuming you don’t shoot too close to a black hole, you’ll just keep going very nearly straight forever. If you can’t breath, your body won’t stay alive for more than about 30 minutes. Gravity is only about 10% weaker at 300km (which is well above the bulk of the atmosphere) than it … so up is the exact opposite on each side of the planet. As one falls through the … 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. It still sounds like I’m making excuses. 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.

Fox News fires key player in its election night coverage, 'I have deep respect for a free and independent press', Advocates react to Biden's sweeping immigration plan, Democrats officially take control of the Senate, Biden leaves hidden message on White House website, Saints QB played season with torn rotator cuff, Lady Gaga wows with exuberant anthem at inauguration, Ken Jennings torched by 'Jeopardy!' 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. 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. Or a geodesic, or a world line in Relativity. Hawking said in 2016: "If you feel you are in a black hole, don’t give up. 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. 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 rocket needs to shoot out a lot of material. As there is no huge gravity pulling us like Earth there is no up or down. 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). ", "Wouldn't that also costs much less fuel since space is a vacuum?". If you simply launched straight up, you'd fall straight down, it's the speed that makes the difference. "But what would happen if you just go straight up, let's say 10,000 kilometers?". In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. Edit - Spelling and grammar. It sounds like you are imagining that what satellites do is go up through the atmosphere, break through into outer space, and hang there. - Shawntay Muskegon,MI,U.S.A. In addition to the theory mentioned by Robert Frost, the generally described theory (as Stephen Hawking does in A Brief History of Time), is that the Universe is at least 4 dimensional (3 space dimensions and 1 time). racetracks are ovals, not squares or rectangles, for a reason. (Although you’d lose consciousness after about 5.) Any slower and you will fall back to your starting point. Wouldn't that also costs much less fuel since space is a vacuum? 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).
