Particles moving faster than light? TOK

What was the anomalous observation in the articles above?

An observation was made that “startled” the science world where showing that particles can travel faster than the speed of light.

 What was the paradigm that was challenged by this observation?

Based on Einstein’s theory that nothing can be faster than the speed of light and which is theoretically proven to be true. What startled them is the observation of appearing particles sent from France to Italy 730km away, where particles that were sent “appeared” to be faster than light.

How was the science community trying to resolve this situation?

It was considered impossible for anything to travel at a faster speed than light because particles that have mass require force to accelerate them, the faster the object moves the more energy is required same goes with mass, the greater the mass the more energy needed to accelerate. Light is a particle with no mass, meaning very little or not energy is required to move it, therefore nothing can be faster than light. This theory was believed to be true and tested there is no way that anything moved faster than light. To make sure, the scientific community had to test it again. As a result, the particles could not be fired faster than light, which then concluded that there was an error in the experiment. Later discovering a cabling issue.
