Friday 5 November 2021 Public Observatory De Jager is organizing a lecture by Jan de Leeuw. The title of the lecture is: “From Big Bang to Baby Boom”. 13.8 billion years after the Big Bang, we live with 7.8 billion people on the shell of a very small sphere in an immensely large and dark universe. That little sphere, planet Earth, or rather planet Ocean, seems to be the only place in the universe where life originated and developed into an enormous diversity. How could that be? Where, when and how did that life originate on Earth and would there be life elsewhere and, if so, what kind of life? Questions that have occupied humanity for a long time. To answer these questions, we embark on a journey of discovery. Everyone is welcome! Start time: 8 pm. Cost: 5 euros. Donors and OSG students are free. Coffee and tea is also free.
