OK, if a nuke would not do the trick, then how about a gravity bomb? I'm think it could easily be built if people would just sit down and focus on it. I figure that if you could some how impose weight on a specific sized mass, then the weight would increase that objects gravitational pull on other objects. Now add in the fact that greater weight is what gravity depends on to push and pull on other objects. Just like the sun pulling on the planets.But any way, why can't we just use an extremely strong gravitational nudge or bump to divert a comet of any other object.<br /><br /> And for the detection system, why not build a sphere laced with many indvidual radar points covering every point or spot on the sphere? This would give the Shere a 360 degree look around the area of the solar system it is set to. Easier explantion, like how a disco ball reflects light in every direction, I don't see why this could not work for radar signals. It's kinda like how in WWII the Navy dropped mines in the ocean to protect harbors or bases. But instead of bombs, they will be radar satellites. Now imagine dropping one of these satellites at certain points throughout the orbit that the Earth uses to circle the sun. Kinda like geostationary satellites, but instead these will be stationary all around the same orbit the Earth takes around the sun.We have GPS, now how about "SSPS" or Solar System Postioning System.<br /><br /> The kind of plan would surely work. Right???<br /> Please reply.<br /> <div class="Discussion_UserSignature"> </div>

Seriously, if caught in time, any asteroid of any size can be induced to miss earth with a truly remarkably tiny impulse.<br /><br />We have already deflected Jupiter! (inches in billions of years, but deflected, nevertheless and all known asteroids are smaller).<br /><br /><br /><img src="/images/icons/smile.gif" /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

A radar cube instead of your disco ball, might be practical. If it rotates and tumbles it sends a pulse in about a billion directions each day which should give excellent coverage. The radar receivers likely should be up to a billion kilometers away in many directions in solar orbits. Atomic clocks likely have sufficient accuracy to make the data meaningful and provide a solar system wide GPS. The pulses need billions of distintive codes so the receiver computers can determine when the pluse was sent, and the direction it was sent in. There is a slight chance of detecting a reflected pulse a month after it was transmitted. Pulses can vary in width, rise time, fall time, increasing or falling carrier frequency = chirp and rising and falling amplitude, but this does not provide nearly enough distintive pulses, so pulse bursts must be sent.

A sphere would cover more areas than a cube. And the sphere would not move, it would remain as motion less<br /> as possible. This would give for a fixed reciever point, also giving better coverage of that area. <div class="Discussion_UserSignature"> </div>
