REOPENED FROM MAY 26TH ON. The Musée royal de Mariemont presents an exhibition about time-space travelling in art, entitled "Bye Bye Future! The Art of Time Travelling". The exhibition wants to explore the fiction and artistic production that tried to materialize this popular fascination that combines fear and hope for the future. Retrofuturism, cyberpunk or steampunk… these are all expressions for alternative futures that both contain nostalgia for an idealized past and fear for the present or future. This elaboration of utopias and dystopias goes hand in hand with important cultural and social paradigm changes like the industrialization of the XIXth century, the European reconstruction after World War II, globalization, the arrival of the internet or artificial intelligence.
