Without the force of gravity, many things behave very differently than we are used to: A burning candle, for example, is not a yellow flame in zero gravity, but a bluish ball. Soap bubbles turn out to be surprisingly thick-skinned, and grains form clusters. Experiments in weightlessness allow us to understand processes that are otherwise overlaid by gravity and we can measure them with high precision. However, the effort involved is great, whether on board a parabolic flight, a rocket or on the International Space Station ISS.
At this Café & Kosmos, Dr. Lucas Kreuzer from the Technical University of Munich will talk about his own experiences with weightlessness and the experiments and findings he has made in the process.
