Could you build a structure so tall that the upper floors were in space?

There has been quite a bit of talk lately about building a space elevator, which works the opposite way; hang a cable from a satellite in geo orbit down to earth, then have an elevator climb up it (see wikipedia: space elevator)\n   In that case, the tensile strength of new nanotube materials is just high enough to make it possible (steel's strength-to-weight is far too low).  Since most materials are much stronger and more stable in tensile strength than in compression, building a tall building to geosynchronous orbit is probably impossible from a materials point of view.  On the other hand, you could build a building lower than geo orbit, but anything released from the top would fall to earth.  You'd have to launch rockets or use a cannon or railgun or something from the top to accelerate them to orbit.

i dunno im thinking about 100 ft  high i dunno ya met wanna ask someone that is smarter than me it would probably range about 100 ft - about 10000000000ft  i dunno

Probably could, but there is a small chance you'll get bent doing it.  Is it worth the risk?  Keep this in mind:  Helicopters, when transporting divers, cruise at a ceiling of 50'.  That is as high as they're willing to go.  \n\nChanges in altitude are very dangerous after diving and should be done cautiously.

It depends on who does the measuring! Skyscraper buffs disagree on whether features like flagpoles, antennas, and spires should be included when measuring building height. \nAlso under dispute is the question of what, exactly, constitutes a building. Technically, observation towers and communications towers are considered structures, not buildings, because they are not habitable. They do not have residential or office space. \n\nSoaring 1,670 feet (509 meters), the Taipei 101 Tower in Taipei, Taiwan appears to be the world's tallest building. But the Taipei 101 Tower's massive 60-foot spire contributes to much of that height. \n\nBefore the Taipei 101 Tower was completed, the Petronas Twin Towers in Kuala Lumpur, Malaysia were described as the tallest buildings in the world. But, like the Taipei 101 Tower, the Petronas Twin Towers get much of their height from spires, not from usable space. \n\nIf you count only habitable space and measure from the sidewalk level of the main entrance to the structural top of building (excluding flagpoles and spires), then Chicago's Sears Tower, built in 1974, may still be the tallest building in the world. \n\nBut none of these buildings will keep their rankings for long. Even taller buildings are on the drawing board. Freedom Tower at the new World Trade Center in New York City is expected to rise 541 meters (1,776 feet) tall, including its enormous spire. \n\nHowever, if spires, flagpoles, and antennas can be counted when we measure building heights, perhaps rankings of the World's Tallest Buildings should include all man-made structures, whether or not they contain habitable space. In this case, the CN Tower in Canada is the world's tallest building. The communications tower and tourist attraction measures 553.33 meters (1,815 ft., 5 inches) tall. \n\nhttp://architecture.about.com/library/bltall.htm

pack it in foam, put a parachute on it... and drop it from the BOTTOM of the 3 story building!!!

I'm sure you could substitute a tall building for a bridge.

a bit over 29,000 feet high

No. You need high density material and mass to create a strong gravitational pull.

Find the tallest building and jump off. ( I beleive in you!)

Being a high rise construction superintendent, this is my experience:\n\n90% of all building heights are decided upon by the Owner and Architect due to business reasons. They decided to do 80 floors or 35 floors because the building will then meet their business model or usage requirements.\n\n5% of all building heights are decided due to local code. The government may own all air space over 500 ft., which means that a building may only go up 40 floors or so before code or local laws prohibit any additional floors.\n\nThe last 5% is due to local environments, such as surrounding infrastructure, geologic conditions, and whatnot. The fact is that we currently have the technology to build in almost any type of environment, regardless of the conditions. The only factor is money and time. Some owners choose to not build high because the cost factor is so prohibitive.

There's space up there. And since space is limitless, I guess sky is so too!

That's like living above Mount Everest.  No, it is not possible.\n\nhttp://bmj.bmjjournals.com/content/vol317/issue7165/images/large/abcoxy5.f2.jpeg

NO way to do it cheap and safe.\nAlso, due to the size, moving is difficult, unless you can build it in parts, and keep it together while using it.

Actually yes, they are planning a "Space Elevator"\n(Warning, while source below is mostly acccurate, the scientific papers could take years to get through)

Maybe somewhere far in the future. It would have to have a geosynchronous orbit, meaning that its orbit matches the Earth's rotation, otherwise the tether would be wrapped around the planet, and/or it would pull the orbitting object(s) to the ground.\n\nBut if we had an elevator going to it, would it really be an orbitting platform? Wouldn't it just be the tallest structure on the planet?

Heights!..How bout that?

Can you design an ultra-light, ultra strong chamber (sphere?) from carbon nanotubes (and resin) large enough yet strong enough that when evacuated to near perfect vacuum it would float?  Can you collect such chambers (honeycomb?) into a dirigible that would raise weights and fly?  Good luck.
