well, sorry, I was wrong. There are many reasons this might be happening, but a blocked number is one possibility. If you fly "straight up into space", you'll still be moving very quickly from west to east. When you shoot a gun in space, things can get pretty weird. 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"? Surprisingly, you probably wouldn’t explode. Get your answers by asking now. 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. spacetime does not curve in on itself, therefore it is impossible to go in a straight line forever and return to where you started. The balloon flies the other way. In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. What is that thing in astronomy that night stars in the sky are dead, gone, don't exist etc. You will wait in torment, like the rich man is still waiting today. 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. That depends on how you define "straight" and "same place", Quote from: Satya link=topic=80836.msg617443#msg617443 date=1603982902. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. There is no up and down in space. In a hypertorus model of the Universe, motion in a straight line will return you to your original location. 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. As one falls through the … 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. In space, the amount of weight that bones must support is reduced to almost zero. Any slower and you will fall back to your starting point. Pretty scary, kids. Is it true that Uranus contains a water ocean beneath the visible part? Down is not towards the earth's South Pole and up is not towards the earth's North Pole. Friends or family can arrange to visit you when you get to prison. Well, there are some other definitions too. orbit is a fall but moving laterally fast enough that you never fall in. Page created in 0.22 seconds with 78 queries. When will Pete Conrad take his rightful place in history as the actual first man to walk on the moon? 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. Discussion. Or a geodesic, or a world line in Relativity. For reasons of repetitive antagonism, this user is currently not responding to messages from; "BOMB DISPOSAL EXPERT. The deeper you go, the heavier the water above you and so the greater the pressure on your body. But the problem is that in the lower atmosphere, going really fast causes a lot of air friction. 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. But the reality of a human exposed to the vacuum of space may be weirder and more bizarre than you ever imagined. https://en.wikipedia.org/wiki/Space_elevator. 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. 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!' you can also express it as it chooses the path that takes the shortest time, they are not exactly the same, although, ah well. The extremely smart people who are part of the space program have worked out the best, fastest, least costly way yo get into space. This is due to gravity. Calling it 'models' or 'interpretations', but it doesn't change the facts. 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. unless the universe is contracting (or will contract in the future) then this is false. Still have questions? The Bible revealed the nature of time long before Stephen Hawking and other physicists started thinking about it. Defining up will help you understand how meaningless your question is. And, it must come out in the direction opposite of the way we want the rocket to go. Wouldn't that also costs much less fuel since space is a vacuum? If we assume that a wavefront 'sweeps' all possible paths. 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. It depends on the direction you want to travel. 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. It must come out at a high speed. 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. And sideways speed is what you need to get into orbit around Earth, without crashing back down. If a 10km asteroid heads for Earth, could a 500 Megaton nuke destroy it? 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. If you are wearing a face mask, you notice that as you dive deeper, the mask presses harder and harder on your face. 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 … This mistaken notion comes from the way we traditionally hold flat maps. 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. But if they would, somewhere exist, Fermat's principle can't be true, am I right? 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). what happens if instead of flying towards mars or another planet you just went straight up. Going straight up would lose you the 1000 mph or so of launching to the east closer to the equator. If you could dive down to the center of Earth, the pressure on your body would be about 3.5 million times as great! So it seemed like a good time to revisit this topic, and clear up a few misconceptions: Misconception No. 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 wouldn’t it make more sense if they went straight up in a line, rather than following a parabolic path? The pressure from the water would push in on the person’s body, causing any space … Rockets are supposed to go into space, right? If you have enough fuel and reach 24,000 mph you will escape from earth. 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. Is a stationary object in space really stationary? (Image credit: NASA (astronaut image)) Shooting giants from the hip. racetracks are ovals, not squares or rectangles, for a reason. 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. Hawking said in 2016: "If you feel you are in a black hole, don’t give up. And if you have a news tip, correction or comment, let us know at: community@space.com. 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. The problem is that you're moving along with the earth. 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. "And to make the question more interesting: when finally arriving there would it be possible to gain enough speed to get into orbit? Presumably, the track of a vehicle that does not experience lateral acceleration. This website uses cookies to improve your experience while you navigate through the website. The air gets thinner and thinner the higher you go, until there's hardly any air at all. It sounds like you are imagining that what satellites do is go up through the atmosphere, break through into outer space, and hang there. 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 . 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 … Also, your ears start feeling the pressure even at 2 or 3 meters (5 or 10 feet) below the surface. It’s kind of like when we look at a globe, she explains. It still sounds like I’m making excuses. If you are in space and the earth is the nearest astronomical object, you fall towards earth. 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. 8 comments. 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. The physicist reckoned there's a chance you could make your way out of one, though you may end up in a different dimension. Lovely. You can see this law when you blow up a balloon and let it go without tying it. In light of the recent launches I was wondering why rockets launch straight up instead of taking of like a plane. Join our Space Forums to keep talking space on the latest missions, night sky and more! Re: What happens if you go straight in space? 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 main issue is one of orthogonal (right angle) motion being less than ideal for going from one direction of motion to another. "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. 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. 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. Edit - Spelling and grammar. - Shawntay Muskegon,MI,U.S.A. You also wouldn’t instantly freeze. 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 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. 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. 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. 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. 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. But they climb straight up for part of the way, so that the atmosphere is much less dense. When you shoot a gun in space, things can get pretty weird. 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. if you go straight up you are still moving in an arc because the planet is spinning. This isn’t a mistake… you will see the exact same thing in every other picture and video of a rocket launch. The first indication something’s up is you are calling and sending text messages, but you get no response. But what would happen if you just go straight up, let's say 10,000 kilometers? Once it reaches its apogee, the bullet will fall. The pressure you feel on your body is due to the weight of the water above you. so up is the exact opposite on each side of the planet. 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. It's better to have all your speed sideways, parallel to the Earth's surface, so that your orbit is as circular as possible. 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. Defining up will help you understand how meaningless your question is. 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. The judge or magistrate will tell you how long you will spend in prison. What happens to those ones 'non existing' in a outcome? If you simply launched straight up, you'd fall straight down, it's the speed that makes the difference. Is there water on other planets in our solar system? You might not be able to speak to family or friends. We Know The Extent Of The Sun, What Is The Extent Of Space Time? 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 :). Once it reaches its apogee, the bullet will fall. The escape velocity there is lower, but still significant. Is it possible for humans to live in another planet? If I want to be cynical, which I most probably is, I would say that without a interpretation statistics are meaningless.
