orbit is a fall but moving laterally fast enough that you never fall in. When you shoot a gun in space, things can get pretty weird. When you go to write a file, it writes that file’s data into the empty blocks. If you could dive down to the center of Earth, the pressure on your body would be about 3.5 million times as great! There are several definitions, yours as good as anyone else I've seen Alan. 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. if you kept going straight up you would have to expend fuel that means you would have to carry it up.. the reason they go into orbit is so they can do a orbital maneuver.. orbital maneuvers require just a small amount of fuel to create a large change in the orbit and this allows a space craft to move to the orbit of the moon or mars or whereever it wants.. a space craft can use a slingshot maneuver too to use the gravity of a planet to pick up speed.. that was done by many unmanned craft such as voyager to get faster without using fuel.. 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. Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. But, since you seem to be looking for a more specific answer than that, let’s take it one at a time. You might not be able to speak to family or friends. The rocket runs out of fuel and you fall back to EARTH. 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. Wouldn't that also costs much less fuel since space is a vacuum? Well, there are some other definitions too. 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. The judge or magistrate will tell you how long you will spend in prison. share. 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. "And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? The deeper you go, the heavier the water above you and so the greater the pressure on your body. "What happens if you go STRAIGHT up into space?". Look out into the depths of the universe and you’ll see galaxies floating edge-on, face-on and at … If I want to be cynical, which I most probably is, I would say that without a interpretation statistics are meaningless. This is the singularity. We Know The Extent Of The Sun, What Is The Extent Of Space Time? 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). 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. 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). 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. 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. Even then, your orbit will skim the top of the atmosphere, where the friction will cause a deorbit in a few days. Furthermore, let's consider what happens if two objects start off along the same path in space-time. If you are in space and the earth is the nearest astronomical object, you fall towards earth. 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. 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. In a hypertorus model of the Universe, motion in a straight line will return you to your original location. Down is not towards the earth's South Pole and up is not towards the earth's North Pole. Lovely. Pretty scary, kids. What would happen to an unprotected person at the bottom of the ocean or in outer space? Once it reaches its apogee, the bullet will fall. 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. Sure. That is why a space elevator is such a great idea, except the mechanics becomes a problem. The Bible revealed the nature of time long before Stephen Hawking and other physicists started thinking about it. When an SSD has little free space, it has a lot of partially filled blocks. If you went "straight" up, you would still have to turn at some point in order to gain that needed horizontal speed. 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? Is it possible for humans to live in another planet? If you want to cross the Atlantic Ocean, you go east. The rocket needs to shoot out a lot of material. And if you have a news tip, correction or comment, let us know at: community@space.com. sounds stupid i know, but when i think about the solar system i see the planets in a row out from the sun. This, however does not account for the motions of that star with respect to other things. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. It depends on the direction you want to travel. however, if the universe is contracting then you will eventually be sucked into nothing and so yeah, youll end up where you started. You will wait in torment, like the rich man is still waiting today. Join Yahoo Answers and get 100 points today. racetracks are ovals, not squares or rectangles, for a reason. Get your answers by asking now. You can sign in to vote the answer. That is certainly <>, but is foolish. 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. The first indication something’s up is you are calling and sending text messages, but you get no response. In space, the amount of weight that bones must support is reduced to almost zero. - Shawntay Muskegon,MI,U.S.A. Discussion. 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. Defining up will help you understand how meaningless your question is. I said ' light always choosing the shortest path between two points'. So you want to get out of the lower atmosphere (the first 60 km or so) as soon as possible. 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. 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. 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. That depends on how you define "straight" and "same place", Quote from: Satya link=topic=80836.msg617443#msg617443 date=1603982902. 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 went straight up, you wouldn't have any sideways speed. Even so, it doesn’t seem to make sense. In space there's nothing to insulate you, so eventually you'll freeze to death. 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). The concepts of "up" and "down" only apply in the gravity well of a moon, planet, or star. (and the Vacuum). depends, are you accelerating or maintaining velocity forever, or do you burn for a limited time and then coast? Over time, calcium normally stored in the bones is broken down and released into the bloodstream. 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. So it seemed like a good time to revisit this topic, and clear up a few misconceptions: Misconception No. In a way it explains everything Alan. well, sorry, I was wrong. 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. And here's something funny about it. 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. If you are in space and the earth is the nearest astronomical object, you fall towards earth. In space, no one can hear you scream.Oooooh! hide. This isn’t a mistake… you will see the exact same thing in every other picture and video of a rocket launch. When will Pete Conrad take his rightful place in history as the actual first man to walk on the moon? It sounds like you are imagining that what satellites do is go up through the atmosphere, break through into outer space, and hang there. 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. 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. what happens if instead of flying towards mars or another planet you just went straight up. 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). So wouldn’t it make more sense if they went straight up in a line, rather than following a parabolic path? 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. "Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit.". Is a stationary object in space really stationary? Surprisingly, you probably wouldn’t explode. Join our Space Forums to keep talking space on the latest missions, night sky and more! 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. If you simply launched straight up, you'd fall straight down, it's the speed that makes the difference. Serious side effects are rare and happen to less than 1 in 1,000 people. Rockets are supposed to go into space, right? This means if you could drive straight up going 60mph you would arrive in outer space in just over an hour's time. what would happen if you went straight up to space and kept going up and up and dident stop? 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. Edit - Spelling and grammar. Going straight up would lose you the 1000 mph or so of launching to the east closer to the equator. https://en.wikipedia.org/wiki/Space_elevator. 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. Gravity is only about 10% weaker at 300km (which is well above the bulk of the atmosphere) than it … And sideways speed is what you need to get into orbit around Earth, without crashing back down. In a flat space the shortest path between two points. ©The Naked Scientists® 2000–2017 | The Naked Scientists® and Naked Science® are registered trademarks created by Dr Chris Smith. As there is no huge gravity pulling us like Earth there is no up or down. How do you think about the answers? 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. There is no straight up or down in space, like has been said, because relevant to us on Earth up is actually away from Earth. There are many reasons this might be happening, but a blocked number is one possibility. 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. The escape velocity there is lower, but still significant. But the reality of a human exposed to the vacuum of space may be weirder and more bizarre than you ever imagined. 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. Unguided toy rockets do this. If you want to fly over the Pacific Ocean, you go west. (3) The water pressure is very high. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. Do I need to introduce a many worlds scenario in where they too exist? the main issue is one of orthogonal (right angle) motion being less than ideal for going from one direction of motion to another. 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. Calling it 'models' or 'interpretations', but it doesn't change the facts. Once it reaches its apogee, the bullet will fall. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. (Image credit: NASA (astronaut image)) Shooting giants from the hip. The ISS, for example, goes at 4860 m/s. Keep taking the medicine, but tell your doctor or pharmacist if these side effects bother you or don't go away: feeling sick (nausea) being sick (vomiting) and diarrhoea ; bloating and indigestion; Serious side effects. Launch profiles are designed to balance these two demands as cheaply as possible, going straight up at first, and then turning parallel to Earth to go sideways. 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." The problem is that you're moving along with the earth. If you see me running, try to keep up.". (Although you’d lose consciousness after about 5.) What happens if I get sent to prison? This mistaken notion comes from the way we traditionally hold flat maps. spacetime does not curve in on itself, therefore it is impossible to go in a straight line forever and return to where you started. 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 … The solution to this problem depends on the strength of Earth's gravitational pull, which in turn is based on its mass. 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.
