In this video, I talk about what the results from the Large Hadron Collider that we have so far mean for the future of particle physics.

The Large Hadron Collider has, contrary to many physicists' hopes, found only the Higgs-boson, and no other fundamentally new particles. But I am sure you recall that before this machine turned on, we heard a lot of talk about other, more exciting things, that it could find: dark matter, new symmetries, extra dimensions, black holes, evidence for parallel universes or even time travel.

Whatever happened to that? Why did physicists think these were reasonable expectations? And what have they now learned from their failed predictions?

Physicists believed that something besides the Higgs should show up at the LHC due to an argument known as "technical naturalness". In my video I explain, however, that this argument is unconvincing, for the new effects predicted this way are not necessary. They are basically wishful thinking.

I then speculate on what will happen to the field in the coming decade.
