We don’t know if life exists beyond Earth. If it does, we don’t know if these lifeforms have technology like us or maybe even better. Perhaps they could detect us? Despite the unknowns, humans have sent messages to the stars in an attempt to communicate with hypothetical aliens.
Host Dr Alfredo Carpineti speaks to Dr Vishal Gajjar, an astronomer with the SETI Institute, about should we, not just can we, actively message aliens and how we are already pretty noticeable to anything out there if they were looking too.
