Learn about gravitational waves and gamma-ray bursts in this lecture from the 104th Kyoto University Marunouchi Seminar, delivered by Professor Kunihito Ioka from the Yukawa Institute for Theoretical Physics. Explore the groundbreaking direct detection of gravitational waves in September 2015, exactly 100 years after Einstein's theory of general relativity. Discover how the merger of two black holes revealed an entirely new view of the universe, demonstrating that black holes are more abundant than previously thought. Examine the historic detection of gravitational waves from binary neutron star mergers in August 2017, accompanied by gamma-ray bursts and electromagnetic waves across all wavelengths, marking the beginning of multi-messenger astronomy. Investigate the ongoing scientific debate about gamma-ray bursts' origins, including the off-axis jet model proposed to explain unusually dim observations. Gain insights into these revolutionary developments in astronomy and their implications for future research.
