Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics? Learn more in this fascinating talk about the latest research into the secret structure of the universe.

Harry Cliff: Have we reached the end of physics?

Have we reached the end of physics?

The Higgs boson discovery at LHC validates the cosmic energy field, explaining mass but leaves profound mysteries unsolved.

The multiverse theory suggests our universe's laws, allowing existence, might be a rare exception in an infinite cosmic lottery.

Universe teeters on fine-tuned numbers; slight shifts could prevent all physical structures, raising profound cosmic queries.
