The video discusses various questions submitted by viewers, including:
1. The first car ever created: The first car was invented by German engineer Karl Friedrich Michael Benz in 1886. It was called the Benz Patent-Motorwagen, had three wheels, and could reach a top speed of 16 km/h.
2. How many people would need to hold hands to reach the moon: Assuming a distance of 384,400 km between the Earth and the moon, and using the length of an outstretched arm as a unit of measurement, it would take approximately 256 people holding hands to reach the moon.
3. Does Daniel think in Portuguese or Italian: Daniel, the host, is Italian-born but has lived in Brazil for a long time. He thinks in Portuguese and has become fluent in the language, although he still translates some words from Italian to Portuguese.
4. The safest place in the world: According to the Global Peace Study, the safest country in the world is Iceland. The safest place, however, is the Fort Knox vault in the United States, which is heavily protected and secure.
5. The temperature of a black hole: Astronomers believe that black holes are extremely cold, with temperatures reaching as low as -273 degrees Celsius. This is because the intense gravity of the black hole slows down the movement of particles, which is related to temperature.
6. How long it will take for the Earth to become uninhabitable: According to a study by biologists from England, the Earth will no longer be habitable in about 7.5 billion years. However, climate change and other factors could affect life on Earth long before that.
Here are the key facts extracted from the text:
1. The first car was created in 1886 by German engineer Carl Frederich Michael Benz.
2. The first car was named Benz Patent-Motorwagen.
3. The car had three thin tires, a wooden chassis, a seat, and a steering wheel that was actually a crank.
4. The car had a 4-stroke engine with 1 horsepower and a top speed of 16 km per hour.
5. The car was sold for 600 German imperial marks, equivalent to around $4,000 today.
6. The distance between the Earth and the Moon is approximately 384,400 km.
7. It would take 256 people holding hands to reach from the Earth to the Moon, assuming a straight line and no obstacles.
8. The safest country in the world is Iceland, with a danger rate of 1.8 per 100,000 inhabitants.
9. The safest place in the world is the Fort Knox vault in the United States, which is surrounded by security cameras, fences, barbed wire, and guarded by over 30,000 soldiers.
10. The temperature of a black hole is extremely cold, with some estimates suggesting -273 degrees Celsius.
11. The Earth will no longer be habitable in about 75 billion years due to the Sun's increasing heat.
12. Climate change may affect life on Earth long before the Sun burns the planet, with some estimates suggesting it could happen in as little as 7 billion years.
13. Only a few resistant microbes would be able to withstand the heat near the end of the Earth's habitability.
