Gravitational waves
The strange phenomena of gravitational waves was predicted by Albert Einstein more than a century ago.
To understand them you need to understand gravitation. In this podcast, professor Niels Obers describes gravitation in Newtonian terms and in the framework of Einstein's General Theory of Relativity. Both descriptions are incomplete but due to research with gravitational waves we may reach to a better understanding of these phenomena.
Since gravitational waves were first detected with certainty in 2015, a number of new gravitational wave detectors are being build and researchers are learning more about the ripples in time, space and the fabric of the universe.
Science Journalist Jens Degett interviews professor Niels Obers from the Niels Bohr Institute at University of Copenhagen.
