Alternative facts, fake news and policy conspiracy theories are shaping our society in the 20th century. The joint art project of Beluga Founder Richard Wilhelmer with Julius von Bismarck and Benjamin Maus calls attention to the power of conspiratorial narrative in the group exhibition "Im Zweifel für den Zweifel" of various prestigious artist like Olafur Eliasson and Juliane Herrmann at NRW Forum Düsseldorf. A fake star above the museum, surveillance technologies, imitations and other exhibits are shown to the audience, while the visitors need to find their orientation in the exhibition. The Fake Star reflects the effects of the post-factual age and our collective understanding of truths. In the digital age, facts are credible if the majority of people in one’s social environment agree on it. That means even the assertion of the existence of a fake star can be seen as a real part of the sky and question the stars themselves while they become an active part of the work of art. The exhibition will be shown from the 21st September- 18th November 2018 at NRW Forum Düsseldorf.
