Here's a concise summary of the provided text:
- The text covers various questions and topics, including why sharks are not afraid of dolphins, the fate of the bodies from the Titanic, the history of Mamonas Assassinas' yellow Brasília, the absence of a bridge over the Amazon River, and why NASA hasn't returned to the moon.
- Sharks are not necessarily afraid of dolphins, but dolphins have ways to defend themselves against sharks.
- The bodies from the Titanic likely decomposed or were consumed by sea creatures over the years.
- The yellow Brasília from Mamonas Assassinas' music video was restored and belongs to Dinho's father.
- Building a bridge over the Amazon River is challenging due to the environment and cost factors.
- NASA hasn't returned to the moon due to political, economic, and technological factors, as well as the availability of unmanned missions.
- Unmanned missions are more cost-effective and safer for exploring celestial bodies.
- Sending humans to the moon is still exciting, but it's currently more practical to use robotic missions for exploration.
1. The video discusses various topics including the remains of the Titanic, the yellow Brasília from Mamonas Assassinas, Solana the blockchain and crypto platform, and the reasons why sharks are not afraid of dolphins, the Amazon River does not have a bridge, and why NASA never returned to the moon after the Apollo 17 mission in 1972.
2. The Titanic sank in 1912, resulting in more than 1,500 deaths. Approximately 340 bodies were found floating in the ocean, but the rest of the bodies were believed to have decomposed at the bottom of the sea.
3. The yellow Brasília from Mamonas Assassinas was a car used in their music video. After the band's plane crash, the car was collected in Brasilia and spent almost a decade deteriorating before it was restored in 2015.
4. Solana is a blockchain and crypto platform that offers support for decentralized applications and large-scale crypto projects. It invites users to participate in a competition where they can receive support of 5 million reais in prizes and capital for their projects.
5. The Amazon River, the second longest river in the world, does not have a bridge due to the difficulty in building one in its environment. The river has extensive swamps and soft soil, and its course, width, and depth change drastically throughout the seasons.
6. Sharks are not afraid of dolphins; in fact, dolphins have several ways of defending themselves against sharks. Their main weapon is their snout, which is made of a very strong bone and has a hard, rounded tip. Some sharks avoid messing with dolphins not out of fear but because they know they could get hurt.
7. NASA planned to return to the moon, but many difficulties, including political and economic obstacles, postponed possible missions. The last time a human set foot on the Moon was in 1972 during the Apollo 17 mission.
