What is a beacon in the context of space exploration?

—A beacon is a way of sending messages to the stars using radio waves to transmit information across space, like a beacon of hope and connection to our universe.

Why is binary language used for communication with extraterrestrial intelligence?

—Binary language is believed to be understood by every form of intelligence in the universe, making it an ideal method for communication with extraterrestrial beings.

What is the Arecibo message?

—The Arecibo message is a radio message sent from Earth to a distant star cluster called M13. It was sent in 1974 as a representation of our solar system and the human DNA structure.

What was Stephen Hawking's warning about making contact with extraterrestrial beings?

—Stephen Hawking expressed concerns about the potential dangers of making contact with advanced alien civilizations that may possess technology and intentions that could be harmful to us.

Are we close to receiving messages from alien civilizations?

—Scientists are working on advanced technologies and algorithms to detect and decode signals from space, and there is a possibility that we might receive responses from alien civilizations as early as 2029.
