Aliens! . . . Where are you?
From ancient beliefs that the Earth was a unique world made by God for humankind to be at the centre of the Universe, to the amazing insights and discoveries that bravely challenged those misconceptions, in this lecture we explore the fascinating theme of life in a Universe in constant change and development, from its very simple and remote origin. What is life and how could it develop on paradise Earth to the high level of diversity and complexity that we see today? Did it all happen just by chance? Recent astronomical observations indicate that there may be millions of solar systems in our galaxy, where life could develop in similar ways. Should we find alien intelligence virtually everywhere?
