I am sure we all remember the experiment announced in September which suggested that neutrinos could move faster than the speed of light which disproved Einstein's Theory of Relativity. This announcement was controversial, being met with excitement and skepticism. The article linked above is about a repeat test of the speed of the subatomic particles. This test was ran at the same laboratory, but by a different group, and the neutrinos were found to not travel faster than light, instead being clocked at precisely the speed of light within a small range of error. This new experiment offered relief to the physics community, ensuring them that a century of physics and relativity were not wrong. Further experiments that will finally put an end to speculation about neutrino speeds will take place at the end of the month.
However, I wonder what it would be like if the original test data was correct. Physics, especially relativity which holds the speed of light to be the Universe's absolute speed limit, would have to be reworked and rewrote. This would have changed much of what we believed to be true.

I believe that this experiment has brought closure to the world of physics, and other fields of science that deal with subatomic patricles called neutrinos. Without these new test results recording that the neutrinos actually travel at the same speed as light, as Suzanne suggested, physics as we know it would have to be modified greatly. From the experimental error made in the first trial of the experiment to determine the speed of neutrinos, everyone who is involved in laboratory research and trials, even high school students like us, could take a lesson; always ensure your equipment is accurate and properly assembled before finalizing your results. This is especially important when dealing with large scale projects, such as this one, where inaccurate results could completely alter the scientific world.
