Do I need to introduce a many worlds scenario in where they too exist? As there is no huge gravity pulling us like Earth there is no up or down. And, it must come out in the direction opposite of the way we want the rocket to go. 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. On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel). Down is not towards the earth's South Pole and up is not towards the earth's North Pole. 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. Look out into the depths of the universe and you’ll see galaxies floating edge-on, face-on and at … 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. If you went "straight" up, you would still have to turn at some point in order to gain that needed horizontal speed. 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 I get sent to prison? When you shoot a gun in space, things can get pretty weird. 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. (Image credit: NASA (astronaut image)) Shooting giants from the hip. In a way it explains everything Alan. 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’s kind of like when we look at a globe, she explains. what would happen if you went straight up to space and kept going up and up and dident stop? What happens if you go straight in space? This means if you could drive straight up going 60mph you would arrive in outer space in just over an hour's time. And what is a 'straight line' in SpaceTime? The Bible revealed the nature of time long before Stephen Hawking and other physicists started thinking about it. so up is the exact opposite on each side of the planet. Wouldn't that also costs much less fuel since space is a vacuum? In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. 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. 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. however, if the universe is contracting then you will eventually be sucked into nothing and so yeah, youll end up where you started. I can't decide on that one. The rocket runs out of fuel and you fall back to EARTH. Furthermore, let's consider what happens if two objects start off along the same path in 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). - Shawntay Muskegon,MI,U.S.A. If I want to be cynical, which I most probably is, I would say that without a interpretation statistics are meaningless. (Image credit: NASA (astronaut image)) Shooting giants from the hip. And if you have a news tip, correction or comment, let us know at: community@space.com. It sounds like you are imagining that what satellites do is go up through the atmosphere, break through into outer space, and hang there. (Ah, yes:) *a table is always good to hide under*, life is too short to drink instant coffee. You will wait in torment, like the rich man is still waiting today. Join Yahoo Answers and get 100 points today. 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. 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. You might not be able to speak to family or friends. 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. 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 … If a 10km asteroid heads for Earth, could a 500 Megaton nuke destroy it? Hawking said in 2016: "If you feel you are in a black hole, don’t give up. But if they would, somewhere exist, Fermat's principle can't be true, am I right? So wouldn’t it make more sense if they went straight up in a line, rather than following a parabolic path? 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. If you want to cross the Atlantic Ocean, you go east. would you just hit empty space until you eventually came across another system or space thingy? 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). But the reality of a human exposed to the vacuum of space may be weirder and more bizarre than you ever imagined. The balloon flies the other way. 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.. And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? 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. 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. The escape velocity there is lower, but still significant. 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. Friends or family can arrange to visit you when you get to prison. Orbiting is a process where the object in orbit is always falling toward earth, but has enough horizontal speed to avoid hitting it. (Although you’d lose consciousness after about 5.) 8 comments. racetracks are ovals, not squares or rectangles, for a reason. 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). But they climb straight up for part of the way, so that the atmosphere is much less dense. The deeper you go, the heavier the water above you and so the greater the pressure on your body. So, consider satellites that go into Geo-sync orbit... that's about 23,600 miles in space. (3) The water pressure is very high. So it seemed like a good time to revisit this topic, and clear up a few misconceptions: Misconception No. If you drove straight up you would arrive in space in just over an hour. If you are wearing a face mask, you notice that as you dive deeper, the mask presses harder and harder on your face. unless the universe is contracting (or will contract in the future) then this is false. Keep all Life Tiles Life-side-up in front of you; looking at the values on the Life Tiles is against the rules. The problem is that you're moving along with the earth. Still have questions?

Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. what happens when you go up or down. "But what would happen if you just go straight up, let's say 10,000 kilometers?". 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. 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 are in space and the earth is the nearest astronomical object, you fall towards earth. In space there's nothing to insulate you, so eventually you'll freeze to death. If you have enough fuel and reach 24,000 mph you will escape from earth. The first indication something’s up is you are calling and sending text messages, but you get no response. "And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? When an SSD has little free space, it has a lot of partially filled blocks. But for straight up, you’d need about 30 km/s, meaning more fuel, and compromises to your payload. 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. Surprisingly, you probably wouldn’t explode. report. orbit is a fall but moving laterally fast enough that you never fall in. If you are in space and the earth is the nearest astronomical object, you fall towards earth. 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 … Going straight up would lose you the 1000 mph or so of launching to the east closer to the equator. . If you went straight up, you wouldn't have any sideways speed. That is not right. spacetime does not curve in on itself, therefore it is impossible to go in a straight line forever and return to where you started. "On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel).". There is NO "straight up" or "straight down" in space. But fortunately, that loss of 100 watts of heat isn't all that much compared to the sheer mass of your body. share. The ISS, for example, goes at 4860 m/s. 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. Defining up will help you understand how meaningless your question is. 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. 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. Astronomers love to remind us that there’s no up or down in space. 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!'

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. For reasons of repetitive antagonism, this user is currently not responding to messages from; "BOMB DISPOSAL EXPERT. If you fly "straight up into space", you'll still be moving very quickly from west to east. Pretty scary, kids. Only use public transport if you have no other option. 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." 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). 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. I said ' light always choosing the shortest path between two points'. 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. ", "Wouldn't that also costs much less fuel since space is a vacuum?". The concepts of "up" and "down" only apply in the gravity well of a moon, planet, or star. In space, the amount of weight that bones must support is reduced to almost zero. There are many reasons this might be happening, but a blocked number is one possibility. But what would happen if you just go straight up, let's say 10,000 kilometers? 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. Skin is almost completely gas-tight and strong enough to withstand a pressure differential of well over one atmosphere. It depends on the direction you want to travel. Get your answers by asking now. 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. Page created in 0.22 seconds with 78 queries. Edit - Spelling and grammar. Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. If you see me running, try to keep up.". "Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit.". If you want to fly over the Pacific Ocean, you go west. As you go deeper into the black hole, space becomes ever more curvy until, at the centre, it becomes infinitely curved. The judge or magistrate will tell you how long you will spend in prison. You can’t breath at the bottom of the ocean. you can also express it as it chooses the path that takes the shortest time, they are not exactly the same, although, ah well. If you are sentenced to prison time you will have to go straight to prison from court. Calling it 'models' or 'interpretations', but it doesn't change the facts. The pressure from the water would push in on the person’s body, causing any space … Career Spaces are extra opportunities to make some money from other players. 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 … Well, there are some other definitions too. 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). Join our Space Forums to keep talking space on the latest missions, night sky and more! 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. 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. You also wouldn’t instantly freeze. It still sounds like I’m making excuses. https://en.wikipedia.org/wiki/Space_elevator. (and the Vacuum). This is the singularity. the main issue is one of orthogonal (right angle) motion being less than ideal for going from one direction of motion to another. We Know The Extent Of The Sun, What Is The Extent Of Space Time? Re: What happens if you go straight in space? 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. "What happens if you go STRAIGHT up into space?". When you shoot a gun in space, things can get pretty weird. 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. And it's better to do this as soon as possible, so you don't have to carry extra fuel to go straight up. Orbiting is a process where the object in orbit is always falling toward earth, but has enough horizontal speed to avoid hitting it. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. Than following a parabolic path several definitions, yours as good as anyone else I 've seen Alan in.
