You have probably heard of the Higgs boson, come across different explanations for its properties. Something about the field that penetrates space interacts with the particles, slowing them down like a thick syrup to give them mass. This may seem like a simple explanation, but as is often the case, it’s too simplistic և somewhat misleading. This is the opinion of Leonard Sassink, an American theoretical physicist and one of the founders of string theory, a professor at Stanford University. So he prepared a whole lecture in which he explained what the Higgs boson was, and how it was related to mass. We hope that everything will become clear to you now, but we do not promise anything.
