Dr Francesco Muia | Unlocking the Universe’s Secrets with Ultra-high-frequency Gravitational Waves

About this episode

In the early 1900s, Einstein revolutionized our understanding of space and time, revealing them as interconnected aspects of the universe’s fabric – known as ‘spacetime’. Spacetime isn’t a rigid background. Like a ball on a trampoline, heavy objects like the Sun warp spacetime around them, drawing the planets into orbits. When heavy objects move extremely fast – such as when two black holes orbit each other and merge or in highly energetic events like those occurring in the early universe – the warping becomes extreme, generating waves that spread through spacetime. These ‘gravitational waves’, first discovered in 2015, offer scientists new tools to explore the universe. Read More
