Event details of Unstuck in time in a ticking cosmos

Location Aula - Lutherse kerk

People can live for a hundred years; stars can live for billions of years. Both have interesting lives that we should learn from. If we zoom-out and consider a whole life it tells a story, but if we zoom-in on the special moments it can be just as instructive. Jason Hessels will talk about how we use radio telescopes to scan the skies in search of short-duration signals that teach us about the extremes of the Universe. Measurements of pulsars, the Universe's near-perfect clocks, have allowed us to test Einstein's theory of gravity and the nature of ultra-dense matter. The fast radio bursts (FRBs) we see from other galaxies provide a new way to illuminate the otherwise invisible matter between stars and galaxies. The Universe looks very different when we zoom-in on these brief moments, but together these events help us understand the grander story that plays out on long timescales. The same is true in our own lives.
