jack_harkness Posted July 11, 2007 Share Posted July 11, 2007 Right, what many people don't know is that there are two types of gravity, positive and negative. At the moment the gravity on this planet has more positive than negative. Positive is what keeps us on earth while negative is what keeps us from getting squashed. Let me put it to you this way if you throw a ball up in the air it doesn't come straight back down as there is another force pulling it upwards, but once the ball reaches a certain height positive gravity acts and pulls the ball back down. So if there was a way to increase the negative gravity to the point it cancels out the positive then I believe that an object will achieve lift, or if there was a way to remove positive gravity then I believe that will give the same effect. Now if you take this theory to the extreme and increase positive or negative gravity to a speed greater than the speed of light then I believe that it would be possible to travel either back or forwards in time. I'm not too sure on the calculations, nor the equipment needed for this but if any of you out there would like to have a go then that would be most grateful. And always remember anything is possible, just the impossible takes a bit longer. Thanx Captain Jack. Link to comment Share on other sites More sharing options...
paladius Posted July 12, 2007 Share Posted July 12, 2007 Captain of what? here's a term to google... "four fundemenatal forces of nature" (pay particulat attention to the one about gravity) let me know what you think. Link to comment Share on other sites More sharing options...
Darby Posted July 12, 2007 Share Posted July 12, 2007 And always remember anything is possible, just the impossible takes a bit longer. So if we remember that "anything's possible" it's possible that when we finally land on Mars and dig two or three meters below the surface that we will discover a layer, say 20 meters thick, of chocolate pudding that completely surrounds the planet?

satown Posted July 12, 2007 Share Posted July 12, 2007 hello jack i think you mean two different types of polarity in which gravity is established. they can be easily understood as positive and negative acceleration. Link to comment Share on other sites More sharing options...
thunderlight Posted July 13, 2007 Share Posted July 13, 2007 Hi there , The positive and negative. I find that one must perpetualy fluctuate between the two until a point of collapse (seperation) is reached, the trick is to make sure one is not left between the two, that seperation is clean, leaving no disruptive trail behind.

Guest Guest Posted July 18, 2007 Share Posted July 18, 2007 "if you throw a ball up in the air it doesn't come straight back down as there is another force pulling it upwards" Not pulling. Pushing. It's called Kinetic energy, which, long story short, is the energy transferred from your hand to the ball. Short story long, you eat food (chemical energy) which undergoes a slow-burn reaction and is converted for your body's usage (in a purer chemical form, basically). When your brain signals (electomagnetically, of which energy also comes from the chemical energy) for your hand to move upwards. Your arm and hand muscles then use the stored energy (chemical) which uses up oxygen for the conversion process (supplied from the bloodstream, lungs, air then plants). As the chemical reaction contracts the muscles in your arm, the energy is then converted into kinetic (movement) energy, which is transferred into the ball. As the ball goes up it loses energy as it is resisted by gravity (or otherwise it would just shoot off into space which would make for some comical golf tournaments). At which point the ball is brought back down to earth. Last time I checked, when I wanted to throw a ball, it was not magically lifted out of my hand by a bizarre form of opposing gravity (even if that would be cool and make me look like I was some master of balls), but I had to use my muscles. I mean, not much point for our muscles if balls and other such items just floated into midair, and then just came back down. Link to comment Share on other sites More sharing options...
