...we will have antigravity engines that we can install on vehicles. Now, I have no proof of this, but I don't need to because I am making a prophecy <img src="/images/icons/smile.gif" /><br /><br />How will antigravity benefit space flight? Well, it will be great for leaving the planet, but the thrust will decrease as you move away from the body. So it's virtually useless for deep space flight. Remember, your thrust vector will have to go through the center of mass of the bodies around you, so you won't be able to achieve LEO with antigravity alone. Maybe GEO, or very slow trips to the Moon. I don't think a star can be used for propulsion.<br />Gravity multiplying will allow for some maneuvers but again, its use will be limited to very short ranges.<br />Antigravity will be great in braking while approaching your target. You can bring your whole ship down to the surface of the Moon, Earth or Mars. To get from Earth to Mars in a lifetime, you still need some sort of impulse exchange.<br />So...I think in less time than any of you think, there'll be antigravity cars, planes and spaceships.<br /> <div class="Discussion_UserSignature"> <p>http://asteroid-invasion.blogspot.com</p><p>http://www.solvengineer.com/asteroid-invasion.html </p><p> </p> </div>
