The narrator, who appears to be drunk, discusses the history of communication, from ancient methods such as yodeling in Switzerland and talking drums in Africa, to modern technologies like telegraphy and the internet. The narrator notes that the speed of message transmission has increased dramatically over time, from 7 kilometers per hour for a marathon runner to the speed of light for modern telecommunications. The narrator also discusses the concept of quantum entanglement and its potential for faster-than-light communication. The video ends with the narrator promoting a "Secret Santa" project, where viewers can send and receive New Year's greetings from strangers, and thanking his audience for reaching a milestone of 1 million subscribers.
Here are the key facts extracted from the text:
1. Yodeling originated in Switzerland and was used by shepherds to communicate with each other over long distances.
2. Yodeling requires perfect control of the larynx and is a complex vocal genre.
3. In ancient times, people used various methods to transmit messages over long distances, including talking drums and runners.
4. The Pony Express was a mail service that used horses to transmit messages across the United States in the 19th century.
5. The first transatlantic telegraph cable was laid in 1858, allowing for rapid communication between Europe and North America.
6. The speed of message transmission increased from 7 kilometers per hour (with a runner) to 30 kilometers per hour (with a horse) to the speed of light (with the telegraph).
7. The first message was sent to space in 1946, and since then, radio signals have been transmitted into space at the speed of light.
8. These signals are now 1.5% of our galaxy and contain messages from humanity, including music and voices.
9. The Voyager 1 probe carries a golden record with a message for aliens.
10. A project called "Secret Santa" allows people to send and receive New Year's congratulations and gifts from strangers.
11. The channel mentioned in the text has over 1 million subscribers.
12. The speed of light is approximately 1 billion 80 million kilometers per hour.
13. Scientists are trying to create a connection faster than the speed of light using twin photons with unique quantum properties.
14. A marathon runner can run approximately 240 kilometers from Marathon to Sparta and back, plus 40 kilometers to Athens.
15. Horses can run out of steam after 15 kilometers and need to be replaced.
16. Persistence hunting is a method used by some tribes to catch animals by running after them for several days.
17. The first transatlantic telegraph cable was laid by Charles Bright and his team in 1858.
18. The cable was over 4,000 kilometers long and took several attempts to lay successfully.
19. The telegraph revolutionized communication and enabled rapid exchange of messages across long distances.
20. Radio signals have been transmitted into space for over 100 years and are now a significant part of our galaxy.
