Cosimo Bambi is currently Xie Xide Junior Chair Professor at the Department of Physics at Fudan University. He received the Laurea degree from Florence University in 2003 and the PhD degree from Ferrara University in 2007. He worked as a postdoctoral research scholar at Wayne State University, IPMU/The University of Tokyo, and LMU Munich. He joined Fudan University at the end of 2012 under the Young Talents Program. His main research interests focus on theoretical and observational studies on black holes. He has published more than 200 papers as first or corresponding author, he has over 13,000 citations, and his h-index is 61 (Google Scholar). He has published several books with Springer. He has received a number of awards, including the Magnolia Gold Award (上海市白玉兰荣誉奖) in 2022 and the Magnolia Silver Award (上海市白玉兰纪念奖) in 2018 from the Municipality of Shanghai, the International Excellent Young Scientists Award from the National Natural Science Foundation of China in 2022, and the Xu Guangqi Prize from the Embassy of Italy in Beijing in 2018.Black holes are the sources of the strongest gravitational fields that can be found today in the Universe and are ideal laboratories for testing Einstein's theory of General Relativity in the strong field regime. In this talk, I will argue that the possibility of an interstellar mission to send small spacecrafts to the nearest black hole, although very speculative and extremely challenging, is not completely unrealistic. Certainly we do not have the necessary technology today, but it may be available in the next 20-30 years. The mission may last 80-100 years, but we would be able to obtain very valuable information about black holes and General Relativity that could be unlikely obtained in other ways.
