Sometimes, it takes a long time before you are proven right. Not that too many people seriously doubted Einstein’s prediction that gravitational waves – ripples in the fabric of space – existed. However, it wasn’t definitively proven until 2016, nearly 100 years after the Jewish scientist first posited their existence. Even in 2016, with the technology available, it took a major event to trigger waves large enough to be detected. That event was the collision of two black holes over a billion light-years away. In 2012, the Higgs boson particle was finally discovered. Predicted back in the 1960s, the subatomic particle was needed to complete the Standard Model. Once the Large Hadron Collider finally proved the particle’s existence, physicists could say that they had a solid grasp of the fundamentals of how subatomic particles behave. It would be easy to go from these and other discoveries and say that everything is going perfectly smoothly in the world of physics. However, that would be to ignor
