If you “take the pulse” of physics and astronomy, it feels as if the interest has seen a general upswing in recent years, something which was clearly noticeable last Saturday. Science shows, CERN, the Higgs boson, the discovery of planets in other solar systems, etc., probably contribute to people of all ages wanting to know more.

Inside the tents, you could to meet researchers and ask questions, participate in experiments, and listen to exciting lectures. There was a long queue to Magnus Näslund’s solar telescope, through which you could look straight into the sun and see the solar prominences, which are hot, gaseous flames ejected into space from the surface of the sun.

On the small stage, Sören Holst talked about thought experiments and what it would look like if you could travel at the speed of light next to a light wave.
