ok here is something I just thought of. I have a laser pointer and i can shine it on the wall and such. I can make the point go from the top of the wall to the bottom of the wall rather fast.
So i went outside and shined the point out in an open field from a balcony in a barn. The point zipped across the field covering a large distance in no time.
so then i put my laser pointer into the sky. I pointed it at the north star and then moved it over across the sky onto another star. Bother stars are equal distance from me but millions of miles away from each other.
Now replace my laser pointer with something that has a solid beam, like a light saber that is 1 billion miles long. Now place a vessel at the end of the light saber. With me on the ground or any stationary point I just have to move my end a little bit to make the other end move billions of miles in only a few seconds.
This works the same way that if a sniper is off just a degree of an angel , his bullet hits feet or yards off.
if you really had a large stick like that, it would require unimaginable amounts of force to move it like that, with one point stationary even, because the other end would have to travel those billions of miles.
wheres 2000AZ5.0GT to chime in? i want to see what he says about this, he really knows his ****.
this is all theoretical that you had the money and time to build such a thing. not a light saber , but a big tower that moves on a henge
think of newtons laws. either way, to put enough force on the tower or w/e to move it reasonably quickly, it would be so much force that the earth would move; theres no stationary point sturdy enough. but thats the least of the problems.
Breaking the speed of light.
