Moon Hoax - Rockets CANNOT work in space | |

Anonymous Coward User ID: 1307701 United States 02/24/2012 05:43 PM Report Abusive Post Report Copyright Violation | one of the biggest hoaxes of all time! Quoting: Anonymous Coward 11057845 rocket propulsion cannot work in space. you get tricked by being told about newtons third law and how the propellant pushes against the body so therefore (equal opposite) has to push the rocket. but newtons third law ironically proves this to be false if viewed from the other way round, the propellant cannot push against a vacuum (zero force) so in turn (equal and opposite) applies zero force to the rocket/vehicle itself. can anyone find me a video of a rocket, firecracker or something similar creating force in a vacuum? "the propellant cannot push against a vacuum" If you don't know so much about science don't make such shitty conclusions. |

Anonymous Coward User ID: 9438655 Brazil 02/24/2012 05:44 PM Report Abusive Post Report Copyright Violation | Sigh... You can't push against the vacuum but you can make the fuel push the ship... Imagine yourself in a chair with wheel, not touching the ground make a strong motion, you will notice you will move. Dont even DARE thinking it was cause of the air... if it was cause of the air we would be able to fly simply by flapping our arms. Dunno if this cleared things up as Im not very good with explanations. |

Anonymous Coward User ID: 1379944 United States 02/24/2012 05:52 PM Report Abusive Post Report Copyright Violation | why do you think that we havn't been further out than 400 mile or so? Quoting: Anonymous Coward 11057845 why so much fuel is used just to get into orbit? clue: air gets thinner. clue: go back to 7th grade physics. The reason it takes so much fuel to get into orbit is that the rocket must reach escape velocity relative to the weight of the rocket in order to escape Earth's gravitational pull. It takes a LOT of power to do that... and fuel itself is heavy and takes up a great deal of volume. |

But the closer you are to center mass of a large object... the stronger the gravitational pull. Hence the reason that some companies will bring satellites down to lower orbits from a higher orbit... the lower orbit will eventually drag the satellite into the atmosphere where it will (ideally) burn up. In a higher orbit the gravitational pull isn't as strong and the satellite is able to orbit the Earth without it's orbit decaying. By your reasoning the fucking moon would be sitting on the face of our planet because the gravitational pull is just as strong there as it is on the face of the planet. |
