0:00:00.732,0:00:03.083
Nas maiores canteiros de obras [br]e pedreiras atualmente

0:00:03.083,0:00:04.083
enormes máquinas são usadas para cavar,[br]corta e erguer pedras

0:00:04.083,0:00:08.696
essas criaturas feitas pelo homem[br]superam seus criadores

0:00:08.696,0:00:12.358
e fazem o trabalho de centenas de homens,

0:00:12.358,0:00:15.488
usando tecnologias hidráulicas modernas.

0:00:15.488,0:00:18.359
Sem esses equipamentos

0:00:19.359,0:00:21.392
construtores nunca poderiam construir [br]arranha-céus modernos

0:00:21.392,0:00:24.692
Mas há centenas de anos atrás

0:00:26.211,0:00:28.335
civilizações antigas estavam realizando[br]o mesmo trabalho

0:00:28.335,0:00:31.507
enquanto construíam seus monumentos [br]e templos usando

0:00:31.507,0:00:33.960
pedras gigantescas.

0:00:33.960,0:00:36.360
Esses enormes blocos,

0:00:37.684,0:00:39.558
muitos pesando mais de 100 toneladas

0:00:39.558,0:00:42.314
seriam um desafio até para a [br]engenheiros atuais.

0:00:42.314,0:00:45.614
Ainda assim, há centenas de anos,

0:00:46.223,0:00:48.523
pessoas os cortavam de rochas sólidas,

0:00:48.523,0:00:50.993
os transportavam por quilometros

0:00:50.993,0:00:53.107
e depois os colocavam no lugar[br]com precisão.

0:00:53.107,0:00:56.036
Mas como?

0:00:56.036,0:00:58.436
Eles cortavam esses enormes blocos de [br]pedra com martelos, cinzéis e fio de cobre

0:00:59.749,0:01:04.815
como os principais arqueólogos sugerem?

0:01:04.815,0:01:08.004
Eles podem os ter levantado [br]e transportado

0:01:08.004,0:01:10.438
sem um sistema de roldanas,

0:01:10.438,0:01:11.932
ou rodas?
