If you simply launched straight up, you'd fall straight down, it's the speed that makes the difference. Do I need to introduce a many worlds scenario in where they too exist? 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 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. 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!' The rocket needs to shoot out a lot of material. Still have questions? So you want to get out of the lower atmosphere (the first 60 km or so) as soon as possible. What would happen to an unprotected person at the bottom of the ocean or in outer space? 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). Skin is almost completely gas-tight and strong enough to withstand a pressure differential of well over one atmosphere. what happens when you go up or down. Even then, your orbit will skim the top of the atmosphere, where the friction will cause a deorbit in a few days. But they climb straight up for part of the way, so that the atmosphere is much less dense. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. (and the Vacuum). 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. ©The Naked Scientists® 2000–2017 | The Naked Scientists® and Naked Science® are registered trademarks created by Dr Chris Smith. So wouldn’t it make more sense if they went straight up in a line, rather than following a parabolic path? 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. 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. Once it reaches its apogee, the bullet will fall. There is NO "straight up" or "straight down" in space. The solution to this problem depends on the strength of Earth's gravitational pull, which in turn is based on its mass. 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. 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. Discussion. That is certainly <>, but is foolish. Over time, calcium normally stored in the bones is broken down and released into the bloodstream. If you want to fly over the Pacific Ocean, you go west. If you are in space and the earth is the nearest astronomical object, you fall towards earth. Sure. Down is not towards the earth's South Pole and up is not towards the earth's North Pole. What is that thing in astronomy that night stars in the sky are dead, gone, don't exist etc. hide. the main issue is one of orthogonal (right angle) motion being less than ideal for going from one direction of motion to another. report. Rockets are supposed to go into space, right? Is it true that Uranus contains a water ocean beneath the visible part? Unguided toy rockets do this. It depends on the direction you want to travel. Defining up will help you understand how meaningless your question is. 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. (Image credit: NASA (astronaut image)) Shooting giants from the hip. - Shawntay Muskegon,MI,U.S.A. racetracks are ovals, not squares or rectangles, for a reason. (Ah, yes:) *a table is always good to hide under*, life is too short to drink instant coffee. That is not right. If you are sentenced to prison time you will have to go straight to prison from court. 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. If you could dive down to the center of Earth, the pressure on your body would be about 3.5 million times as great! "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 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). https://en.wikipedia.org/wiki/Fermat%27s_principle, Quote from: yor_on on 01/11/2020 20:50:21, Is "Space" distinct from "nothingness"? Your blood will also not boil. 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.. 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. The Bible revealed the nature of time long before Stephen Hawking and other physicists started thinking about it. "What happens if you go STRAIGHT up into space?". unless the universe is contracting (or will contract in the future) then this is false. save. Edit - Spelling and grammar. Friends or family can arrange to visit you when you get to prison. well, sorry, I was wrong. This website uses cookies to improve your experience while you navigate through the website. You can’t breath at the bottom of the ocean. 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. This is due to gravity. Going straight up would lose you the 1000 mph or so of launching to the east closer to the equator. Re: 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. 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. There are several definitions, yours as good as anyone else I've seen Alan. 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. This, however does not account for the motions of that star with respect to other things. what happens if instead of flying towards mars or another planet you just went straight up. 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 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. (3) The water pressure is very high. . What happens if I get sent to prison? Or a geodesic, or a world line in Relativity. But the reality of a human exposed to the vacuum of space may be weirder and more bizarre than you ever imagined. 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 pressure you feel on your body is due to the weight of the water above you. 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. however, if the universe is contracting then you will eventually be sucked into nothing and so yeah, youll end up where you started. We Know The Extent Of The Sun, What Is The Extent Of Space Time? Get your answers by asking now. 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.
