00:00:00.732 --> 00:00:03.083
Nas maiores canteiros de obras 
e pedreiras atualmente

00:00:03.083 --> 00:00:04.083
enormes máquinas são usadas para cavar,
corta e erguer pedras

00:00:04.083 --> 00:00:08.696
essas criaturas feitas pelo homem
superam seus criadores

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

00:00:12.358 --> 00:00:15.488
usando tecnologias hidráulicas modernas.

00:00:15.488 --> 00:00:18.359
Sem esses equipamentos

00:00:19.359 --> 00:00:21.392
construtores nunca poderiam construir 
arranha-céus modernos

00:00:21.392 --> 00:00:24.692
Mas há centenas de anos atrás

00:00:26.211 --> 00:00:28.335
civilizações antigas estavam realizando
o mesmo trabalho

00:00:28.335 --> 00:00:31.507
enquanto construíam seus monumentos 
e templos usando

00:00:31.507 --> 00:00:33.960
pedras gigantescas.

00:00:33.960 --> 00:00:36.360
Esses enormes blocos,

00:00:37.684 --> 00:00:39.558
muitos pesando mais de 100 toneladas

00:00:39.558 --> 00:00:42.314
seriam um desafio até para a 
engenheiros atuais.

00:00:42.314 --> 00:00:45.614
Ainda assim, há centenas de anos,

00:00:46.223 --> 00:00:48.523
pessoas os cortavam de rochas sólidas,

00:00:48.523 --> 00:00:50.993
os transportavam por quilometros

00:00:50.993 --> 00:00:53.107
e depois os colocavam no lugar
com precisão.

00:00:53.107 --> 00:00:56.036
Mas como?

00:00:56.036 --> 00:00:58.436
Eles cortavam esses enormes blocos de 
pedra com martelos, cinzéis e fio de cobre

00:00:59.749 --> 00:01:04.815
como os principais arqueólogos sugerem?

00:01:04.815 --> 00:01:08.004
Eles podem os ter levantado 
e transportado

00:01:08.004 --> 00:01:10.438
sem um sistema de roldanas,

00:01:10.438 --> 00:01:11.932
ou rodas?

00:01:11.932 --> 00:01:13.623


00:01:13.623 --> 00:01:17.053


00:01:17.053 --> 00:01:20.553


00:01:26.377 --> 00:01:29.543


00:01:29.543 --> 00:01:33.551


00:01:33.551 --> 00:01:35.674


00:01:35.674 --> 00:01:37.103


00:01:37.103 --> 00:01:39.303


00:01:40.372 --> 00:01:43.364


00:01:43.364 --> 00:01:44.674


00:01:44.674 --> 00:01:48.274


00:01:48.274 --> 00:01:52.898


00:01:54.016 --> 00:01:56.116


00:01:56.121 --> 00:01:59.202


00:01:59.202 --> 00:02:01.097


00:02:01.097 --> 00:02:03.261


00:02:03.261 --> 00:02:06.261


00:02:06.843 --> 00:02:09.243


00:02:10.959 --> 00:02:15.208


00:02:15.208 --> 00:02:18.273


00:02:18.273 --> 00:02:19.326


00:02:19.326 --> 00:02:24.226


00:02:24.563 --> 00:02:30.736


00:02:30.736 --> 00:02:34.258
