ICG outreach activities recently reached Mexico City, where Gianmassimo Tasinato gave a public lecture in one of the main high schools. A crowded auditorium of interested students listened to the lecture, curious to see what happened during the first instants of our universe life. The students were very surprised to know how much we can scientifically say about the origin of the universe, and how much more we still need to learn. Nevertheless, at the end of the lecture the most astonished person was speaker himself, surprised by the large number and deepness of the students’ questions.
