We don't know. Also, if you're interested, Space Engine is a free downloadable universe simulator that's pretty nifty and helps you start to appreciate the scale of the universe. You get taller: Gravity on earth compresses our spine, which doesn’t happen in space, as fluids flow between the spinal disks. There are two reasons for this. If you lift off from the North Pole and keep going, you will leave the solar system. Press J to jump to the feed. If this eventually leads to a relationship or if you’re in a relationship right now, you have to show her that you can give her space … What's beyond that point is quite a guess. Down is therefore towards the earth's center and up is away from the earth's center when close to the earth. If you flew up, you would soon be coming right back down again, since there is no way to lift eno. Of course, what that "something" might be would be anyone's guess, and I'd guess that anything would likely be many light years away. Keep up to date with the latest reviews in All About Space – available every month for just £4.99. If you didn't age, perhaps you could even wind up seeing the back of your own head just by looking for long enough, as your eyes would eventually encounter the light emitted from your own origin. Are all the planets in our solar system level? NASA finally has an answer. If you answered that on Earth the objects fall due to gravity, but in space they don’t because there is no gravity, then I’m afraid your answer is far from the truth. All the planets are in constant motion around the Sun and are never actually lined up like that. Except for, the fact that, by the time your craft would get there, that star would probably have moved along in it's orbit around the galactic center by quite a ways. Up is only relative to where you want up to be relative to. Does the engine of a space shuttle produce sound as it orbits earth? Up and down only applies to being on the surface of a planet or object with gravity. New comments cannot be posted and votes cannot be cast, More posts from the explainlikeimfive community. Most likely just more planets and stars, but we can't know for sure. There's no air in space (it's kind of part of the definition), which means there's no oxygen. Like instead of going "left" towards Venus or "right" towards Mars. Up and below are very relative terms in space. Up and down don't really mean anything if you're in microgravity. Eventually, long after your death, your craft would pass by pretty close to Polaris (the north star) since that was the direction you were headed at liftoff. Don't Panic! Venus and Mars are left and right of the Earth only in diagrams showing the distance the Sun. Regardless of thre direction that you go you would conitnue to go in the dirction forever as the Universe is expanding at the speed of regardless of ther direction that you were too use. our solar system is tilted roughly 63 degrees. It would be a fairly boring trip since most of it is just empty space. When you shoot a gun in space, things can get pretty weird. Also, the rotation of the earth (spin on it's axis) can give you added velocity, making it easier to reach escape velocity from areas farther away from the poles, where you aren't really "moving" with the planet's rotation in a circular pattern, but more or less just spinning in place. Once you reach space it's a sideways run to the moon, mars, etc. There are no lines in space either. What happens to astronaut poop? They are actually much farther from each other and from the Sun than drawn, and they move around the Sun along those lines. Whichever the condition, though, your body would last for a … I'd guess you'd probably run into something eventually, depending on the position of the Earth in its orbit and the sun in our galaxy. If space is infinite what happens if you just keep going up? Where would one end up? (Image credit: NASA (astronaut image)) Shooting giants from the hip. There are no lines in space either. Get your answers by asking now. If you are in space and the earth is the nearest astronomical object, you fall towards earth. Eventually, some object with mass would have the gravity to pull you into orbit around it, or even into it, but essentially, you would continue along your trajectory indefinitely until something (such as gravitational perturbations) altered your course. Eventually you'd get to the edge of waht is the observable universe for us. Okay, let's say you were, however, going to lift off from the north pole, and go "straight up" forever. When will Pete Conrad take his rightful place in history as the actual first man to walk on the moon? What time is best to watch Uranus rising? Perhaps a few comets, assuming you could keep yourself alive long enough for it to be relevant. Going "up" from Australia is very different than going "up" from Canada for example. There is no "up" in outer space...the term only makes sense when you are in the gravitational field of a planet. And yes, if you were to leave earth and keep flying in one direction you would keep finding planets and galaxies. Going "up" from Australia is very different than going "up" from Canada for example. is it the same for everything? They are everywhere. You would end up in interstellar space in the direction of the North Celestial Pole. So for the span of a human lifetime, you'd probably end up nowhere in particular. So your distance from the center of earth's gravity at the pole is closer, and so escape velocity is slightly greater. But your blood doesn't know that. They just keep going around the Earth. Is there water on other planets in our solar system? First of all, by launching from the North Pole, you would be wasting a lot of unnecessary fuel just to escape earth's gravitational pull. Are there other planets and things on different levels? If you keep going, you won't end up anywhere except in the middle of outer space. For instance, at the distance of the moon it is down to 1.4 km/sec. Explain Like I'm Five is the best forum and archive on the internet for layperson-friendly explanations. There is no friction in space, so once you start moving, you keep going in that direction unless some other force acts on you (like gravity). You can use Storage Sense to delete unnecessary or temporary files from your device. Not all solar systems and planets are on a single plane. If a 10km asteroid heads for Earth, could a 500 Megaton nuke destroy it? But, as far as where you would "end up" it's quite possible you would never reach a final destination. How Long Can You Stay in Space, and What Happens If You Stay Too Long? Read on. But I bet you don't know what it looks like in outer space. Also what's below us? If you turn on Storage Sense, Windows will automatically free up space by getting rid of files you don't need, like temporary files and items in the Recycle Bin, when you're low on disk space or at intervals you specify. Not all solar systems and planets are on a single plane. What Happens to the Human Body in Space? A2A Rockets don't go up to get to outer space. In 45 billion years' time, the edge of the observable universe will be an extra 45 billion light-years away. In space, this doesn’t happen. "up" means away from the Earth in any direction. In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. This is no different that interstellar space in any other direction. If you keep going, you will leave the Milky Way galaxy. If you keep climbing at 50 mph, you eventually reach a height where the escape velocity is less than 50 mph. Press question mark to learn the rest of the keyboard shortcuts. First, a little explanation about directions. Biden signs executive orders reversing Trump decisions, Biden demands 'decency and dignity' in administration, Democrats officially take control of the Senate, Biden leaves hidden message on White House website, Saints QB played season with torn rotator cuff, Networks stick with Trump in his unusual goodbye speech, Ken Jennings torched by 'Jeopardy!' Still others have gone out to explore space. Is it possible for humans to live in another planet? How do you think about the answers? I think what you are asking is what happens if you travel at right angles to the plane of the solar system. Also, if there were an emergency, the astronauts would need to be in good shape to get out of the Space Shuttle or Space Station quickly. If you were in a space suit, you usually have little thrusters to help you move around, so you could probably control where you are going using them. Lovely. In an extreme environment like space, it would only take about 15 seconds for your body to use up all the oxygen in your blood. If someone travelled to Mars, what gas stations would they stop at along the way to refuel. As agriculture becomes more efficient, people abandon jobs in that shrinking and difficult sector and instead take up ones in urban manufacturing or service. That's as far as we can see from earth. Getting there would take a good 45 billion years if you'd travel at the speed of light! However, the planets are placed close together in the picture so that they fit. Some have gone to other worlds. Just adding in that relative to the plane of the galaxy, our solar system is tilted roughly 63 degrees. You'd have to travel for millions of years between each galaxy before you get to the next one. The earth "bulges" at the equator and is slightly flattened at the poles. There is no "up" and "down" in space. Data from astronauts who spent 340 days in orbit will add to almost 55 years of research on how low gravity sends Earthlings for a loop (It's an oblate spheriod, not a perfect sphere). But I get what you're asking. At first, it's very bright. And that the overall shape of the observable universe appears to be vaguely sponge-shaped. Weakened astronauts would be less able to do tasks while in space, Hagan says. You can sign in to vote the answer. NASA isn't sure what to do with corpses in space, but they may need to figure it out soon. 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. Join Yahoo Answers and get 100 points today. But if you’re planning an out-of-this-world trip, here are some of the things to expect. But then, as your eyes adjust to the light, you start to piece together your surroundings. ... That includes the heart, which shrinks a little, the neck muscles that hold up our heads, and our calves. At which point you could shut your engine off and continue away from the Earth forever without ever having the reach the 11 km/s escape velocity needed from the surface of the Earth. Up and below are very relative terms in space. Chances are, you might come across some debris, say, at the outer edges of the solar system, but you would not encounter any planets in our solar system, they just don't orbit our sun in that plane. What if you all of a sudden found yourself floating in space without a spacesuit? You want to give her space because if she’s going through something personal or even if you thought you were too overbearing, then it’s vital that you give her space. But to keep going upwards would be the exact same thing sameat going off in everyother direction. But, a lot of the things that have been sent are still in orbit. You can only get there by starting out 45 billion years ago, though. To achieve orbit, a spacecraft must accelerate to 17,600 km/h sideways or they will just fall back to Earth. Don't get too excited though. The terms become largely irrelevant, with up meaning nothing more than "whatever is above where my head happens to be". Some have come back to Earth. Tags: Astronaut , Boil , Carbonated Drink , China , Freeze , Helmet , Oxygen , Particles , radiation , space , vacuum Continue Reading. In the latter case, you’ll burn out, at which point, you’ll be influenced by the gravity of everything on everything else and because of the way that chaos works, you’ll eventually get nudged into some sphere of influence or another, at which. Gravity is a centrally attractive force, so "going down" means falling or being pulled towards the center of the nearest massive object. They landed, or burned up in the atmosphere. Continue Reading. This has been going … 1) You get weaker The skeletal muscle system is the largest organ system of the human body. But the effect isn’t permanent. If you keep going, you will leave the Milky Way galaxy. A lot of things have gone up. Of course, you will burn a lot more fuel reaching that distance at 50 mph than you would if you just accelerated up to 11 km/sec right at the start. Alternatively you can subscribe here for a fraction of the price! Rockets don't go up, they go sideways. Still have questions? So a galaxy is a collection of loads of solar systems, and the solar systems are made up of some planets, moons, dust and one or more suns.
