I am talking about gadgets we see in science fiction movies that obey the laws of physics of our universe and could theoretically be constructed, barring the limitations of materials, energy and time faced by our civilization at the moment.

    Space elevators need to have the majority of their mass higher than geostationary orbit to hold it up, which is 22000 miles above the earth. So I suppose it wouldn’t wrap around the planet more than once. And while true you can do more damage with an asteroid, it would be a far easier target for a terrorist group than something that far away.
