[00:00:00]How do you build the impossible?

[00:00:02]>> [music] >> You turn gravity completely upside down.

[00:00:06]In 1883 Barcelona, Antoni Gaudí [music] began the massive Sagrada Familia.

[00:00:12]He planned 18 colossal spires reaching 566 feet high.

[00:00:17]>> [music] >> Traditional Gothic cathedrals relied heavily on bulky external flying buttresses. [music] Gaudí refused them, calling buttresses an architectural admission of failure.

[00:00:30]To solve [music] this, he turned to pure, elegant inverse physics.

[00:00:35]Inside his studio, he built a massive hanging rope model.

[00:00:40]Weighted sandbags pulled interconnected strings down into perfect [music] catenary curves.

[00:00:46]Gravity naturally calculated the absolute optimal load distribution [music] for him.

[00:00:52]By photographing these hanging chains and flipping the images upside [music] down, Gaudí discovered a brilliant, self-supporting tree-like column geometry for stone.

[00:01:03]This channeled immense [music] roof weight directly into the ground flawlessly.

[00:01:08]A 19th-century [music] physics exploit still guiding this masterpiece's completion today.
