Building skills a two in the second half of the podcast, the host is interviewing astronomer alien guest about contacting extra terrestris. Listen to the conversation and complete the notes below. Should we try to contact extra terrestris? Or is IT too dangerous with me in the studio as astronomy in guest, I lean, is that even possible to send messages to aliens? Yes. it's possible. It's not easy though. We need to figure out what to say to extra terrestrial, as well as how to say IT. So how can we communicate with the completely unfamiliar form of life? Well, we won't be able to speak to them in any human language, or even with body language. Their bodies are probably nothing like ours. For instance, waving hello wouldn't mean much of, i've never seen arms or hands. So one of the big chAllenges is dealing with the difficulties of communicating across space and time, and bridges an extremely wide cultural gap. How are scientists approaching this problem? We need to find a common language. We are currently thinking beyond words, two popular suggestions for a universal language, or maths and science. But the idea of messaging extra restore al intelligence brings up another big question, should we what's your take on IT clean? Well, scientists disagree, but i'm all in favor of messaging extra arrest trials because we could learn so much about life, the universe and even ourselves from them. But some are worried about the potential dangers of communicating with a completely unknown civilization. What are the potential dangers? We can't know for sure, but we can make a guess. Most scientists agree that if there are intelligent extra restore al civilizations, they are probably a lot older than hours. That means they have had more time to develop advanced technologies than we have. If those aliens are friendly, I don't see anything wrong with contacting them. If they're not, then reaching out to them could be a horrible idea.
