Temporary exhibition on the Einstein Telescope

A journey into the mysteries of the universe
The darkest parts of the universe are full of mysteries. But what if there was a high-tech underground observatory that allowed us not just to see but to listen? What would black holes tell us? What message would an exploding star leave behind?

The Einstein Telescope may help us shed some light on these questions. It doesn’t exist as yet, but the science behind it… is already moving full speed ahead.

In our temporary exhibition, we take you on a journey to the darkest and most mysterious parts of the universe. So if you’re coming to Technopolis, get ready for a cosmic journey of discovery!

From mysteries in the dark universe…

We mainly learn about the universe through radio and optical telescopes: we observe stars, nebulae and planets. But… most of the universe is dark. And that’s precisely where the most spectacular events take place, such as black holes colliding with tremendous force.

Such massive cosmic events create ripples in space that we call gravitational waves.

… to ground-breaking discoveries

Once these gravitational waves reach Earth, the Einstein Telescope will detect them and we’ll learn more about space than ever before. That may all sound a bit abstract, so our aim in this exhibition is to explain things in a way that’s straightforward and light-hearted.

For instance, we challenge you to get close to a black hole. Or – just as fun – to hear the difference between two black holes colliding and a star exploding.

Investigate how the Einstein Telescope will work

Totally on board? Then you’re ready to step into the role of researcher yourself. For example, you can go on a virtual reality journey past neutron stars, experiment with the principle of an interferometer (using lasers) and study a 3D model of the Einstein Telescope. 

Fancy something even more exciting? Why not take part in a detective game and find out which cosmic event corresponds to which waves?

Join us on a journey into the future

The Einstein Telescope has not yet been built. And that’s what makes it even more fun: you’ll find out not just what we already know, but what we’ll only be able to discover in the near future. The Einstein Telescope means we’ll have:

  • a higher chance of detecting rare cosmic events,
  • a better understanding of black holes, supernovae and neutron stars, and
  • a completely new way of exploring the dark’ universe that optical telescopes can’t reach.

And with a bit of luck, the Einstein Telescope will be built close to the Belgian border!

And why Einstein Telescope’?

Because Albert Einstein predicted as early as 1916 that massive cosmic events cause gravitational waves. A fitting tribute, then.
