What are the defined limits of height - of a structure on the earth's surface, man-made or natural?. Why, in principle, will it NOT be possible for us to construct buildings of ANY given height? Ignoring for the moment practical issues of use of such a building, how lifts will work and suchlike, can a stable structure of tens or hundreds of miles in height be constructed even in theory? It wouldn't matter to me what the ultimate appearance of this building was, i.e. whether it had the familiar needle- like profile of a city skyscraper or resembled a huge artificial mountain; I'd just like to know whether it can, in principle, be done. And if so, could this building then be used to allow us to access outer space? I have this mental image of a spidery network of metal girders, starting out really broad at ground level and tapering up towards the summit - something resembling the Eiffel tower except on a much, much bigger scale. Irrespective of the answer to that question, assuming it COULD be done, and that we had somehow constructed a building say 200 miles high, would we still need a rocket to provide us with sufficient acceleration to escape the earth's gravity? Much appreciated
