Why are such experiments to explore the physical nature of our universe so paramount to human endeavor ?
If you drive a car and hit against another rigid object you might wanna know how hard it will affect you. You might not want to experience that real time. You might wanna hire some confident engineers to do the job in a laboratory. They will take equations that were discovered a century before and simulate the forces in a mechanical setting to give you answers that will be like logical umbrellas. [Or spherical cows !!]
But there are also forces and equations and structures we have stumbled across which we experience but don’t understand. What they will bring us 100 years from now is something worth giving a consideration, a worth that runs into billions of dollars, as world wide efforts of finding the deepest secrets of nature.
