Communication

Radio-Waves

To find possible ET life, Radio signals are used.

SETI are scientific searches using electromagnetic radiation for signs of transmission

Proposed Quantum communications as a form of communication

Techno signatures

If they were advanced enough they could use megastructures like a lighthouse

Reflection

This lesson was fun and engaging, we learnt more about extraterrestrial life and communications. We did a Kahoot to test our knowledge and it was quite fun and helped me learn better. Ian was clarifying our doubts and being a good teacher. To conclude this lesson was interesting and fun. we can apply this in the future when people ask us why we have not found Aliens.
