This mistaken notion comes from the way we traditionally hold flat maps. Well, there are some other definitions too. Unguided toy rockets do this. sounds stupid i know, but when i think about the solar system i see the planets in a row out from the sun. The escape velocity there is lower, but still significant. Even then, your orbit will skim the top of the atmosphere, where the friction will cause a deorbit in a few days. 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. But they climb straight up for part of the way, so that the atmosphere is much less dense. How do you think about the answers? 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. And, it must come out in the direction opposite of the way we want the rocket to go. It still sounds like I’m making excuses. And it's better to do this as soon as possible, so you don't have to carry extra fuel to go straight up. the main issue is one of orthogonal (right angle) motion being less than ideal for going from one direction of motion to another. Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. As there is no huge gravity pulling us like Earth there is no up or down. Down is not towards the earth's South Pole and up is not towards the earth's North Pole. (Although you’d lose consciousness after about 5.) well, sorry, I was wrong. This isn’t a mistake… you will see the exact same thing in every other picture and video of a rocket launch. 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. So you want to get out of the lower atmosphere (the first 60 km or so) as soon as possible. Astronomers love to remind us that there’s no up or down in space. Join our Space Forums to keep talking space on the latest missions, night sky and more! In a nutshell, a rocket must curve its trajectory post-launch, if it wants to enter the Earth’s orbit. If you see me running, try to keep up.". If a 10km asteroid heads for Earth, could a 500 Megaton nuke destroy it? 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. . Or just a definition of light always choosing the shortest path between two points, from which follows that if one follow the light one can't go wrong :). if you go straight up you are still moving in an arc because the planet is spinning. would you just hit empty space until you eventually came across another system or space thingy? 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. No big deal. Any slower and you will fall back to your starting point. 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. what happens if instead of flying towards mars or another planet you just went straight up. The extremely smart people who are part of the space program have worked out the best, fastest, least costly way yo get into space. But if they would, somewhere exist, Fermat's principle can't be true, am I right? The problem is that you're moving along with the earth. 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. 8 comments. 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. 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. 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. In space, the amount of weight that bones must support is reduced to almost zero. 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. ©The Naked Scientists® 2000–2017 | The Naked Scientists® and Naked Science® are registered trademarks created by Dr Chris Smith. Once it reaches its apogee, the bullet will fall. This means if you could drive straight up going 60mph you would arrive in outer space in just over an hour's time. You can see this law when you blow up a balloon and let it go without tying it. Keep all Life Tiles Life-side-up in front of you; looking at the values on the Life Tiles is against the rules. Page created in 0.22 seconds with 78 queries. 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. In a hypertorus model of the Universe, motion in a straight line will return you to your original location. 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. The pressure from the water would push in on the person’s body, causing any space … That is why a space elevator is such a great idea, except the mechanics becomes a problem. 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. "Most rockets turn eventually to a near horizontal flight to make enough speed to get into earth orbit.". (3) The water pressure is very high. share. That is not right. There are many reasons this might be happening, but a blocked number is one possibility. 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.. 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. Join Yahoo Answers and get 100 points today. The rocket runs out of fuel and you fall back to EARTH. This law also tells us how to build a powerful rocket. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. you can also express it as it chooses the path that takes the shortest time, they are not exactly the same, although, ah well. This is the singularity. Calling it 'models' or 'interpretations', but it doesn't change the facts. If you are in space and the earth is the nearest astronomical object, you fall towards earth. There is NO "straight up" or "straight down" in space. Serious side effects are rare and happen to less than 1 in 1,000 people. Pretty scary, kids. 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 … There is no up and down in space. 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. On normal launches any rocket has to get to speed within the atmosphere (using tons of fuel). Wouldn't that also costs much less fuel since space is a vacuum? You will wait in torment, like the rich man is still waiting today. 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 … 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. (Image credit: NASA (astronaut image)) Shooting giants from the hip. Lovely. If you want to cross the Atlantic Ocean, you go east. It's better to have all your speed sideways, parallel to the Earth's surface, so that your orbit is as circular as possible. "And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? If you simply launched straight up, you'd fall straight down, it's the speed that makes the difference. There's a pretty good wikipedia article about how this is managed called Gravity Turn. It’s kind of like when we look at a globe, she explains. You might not be able to speak to family or friends. And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? It must come out at a high speed. When you arrive in England, go straight to the place you’re staying to self-isolate. (ie you can go "straight" in a circle around a star). 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. ... once they get above most of the atmosphere, and additional speed does not cause too much more friction. The judge or magistrate will tell you how long you will spend in prison. 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. 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 … 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. You can’t breath at the bottom of the ocean. 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 fortunately, that loss of 100 watts of heat isn't all that much compared to the sheer mass of your body. If we assume that a wavefront 'sweeps' all possible paths. 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." however, if the universe is contracting then you will eventually be sucked into nothing and so yeah, youll end up where you started. The deeper you go, the heavier the water above you and so the greater the pressure on your body. 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. • 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. Presumably, the track of a vehicle that does not experience lateral acceleration. In a flat space the shortest path between two points. 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/Fermat%27s_principle, Quote from: yor_on on 01/11/2020 20:50:21, Is "Space" distinct from "nothingness"? What happens if you go straight in space? As you go deeper into the black hole, space becomes ever more curvy until, at the centre, it becomes infinitely curved. What happens if I get sent to prison? 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. Your blood will also not boil. But what would happen if you just go straight up, let's say 10,000 kilometers? 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. Re: What happens if you go straight in space? And sideways speed is what you need to get into orbit around Earth, without crashing back down. Over time, calcium normally stored in the bones is broken down and released into the bloodstream. ", "Wouldn't that also costs much less fuel since space is a vacuum?". Rockets are supposed to go into space, right? Is there water on other planets in our solar system? 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. (and the Vacuum). And here's something funny about it. 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. "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. The air rushes out of the mouth of the balloon. Orbiting is a process where the object in orbit is always falling toward earth, but has enough horizontal speed to avoid hitting it. - Shawntay Muskegon,MI,U.S.A. If you are in space and the earth is the nearest astronomical object, you fall towards earth. 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. The solution to this problem depends on the strength of Earth's gravitational pull, which in turn is based on its mass. 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. 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. Is it true that Uranus contains a water ocean beneath the visible part? In a way it explains everything Alan. Discussion. I said ' light always choosing the shortest path between two points'. But the reality of a human exposed to the vacuum of space may be weirder and more bizarre than you ever imagined. Defining up will help you understand how meaningless your question is. In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. Only use public transport if you have no other option. That would require much more fuel, and fuel is the heaviest part of every launch, so more fuel increases the total size of the launch vehicle and the cost. When you shoot a gun in space, things can get pretty weird. Edit - Spelling and grammar. 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 . In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. And if you have a news tip, correction or comment, let us know at: community@space.com. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. There are several definitions, yours as good as anyone else I've seen Alan. (Ah, yes:) *a table is always good to hide under*, life is too short to drink instant coffee. 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). Career Spaces are extra opportunities to make some money from other players. What is that thing in astronomy that night stars in the sky are dead, gone, don't exist etc. 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 … Is a stationary object in space really stationary? 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.
