quantities must be adjusted, as well. The only way for them to remain the same going in and coming out is for the mass to change in order to compensate for the way velocity changes. As a result, the faster you go, the heavier you get. As you measured by someone at rest. This means that there is a lowest mass (the rest mass) that is measured in the frame in which the thing is at rest. A shocking result of this is that mass becomes seen as a form of energy. This is summed up in the most famous equation in all of science, Emc 2 : The amount of energy pent up in a massive object is equal to the mass of the object multiplied by the square of the speed of light. We now see another reason that nothing can move faster than the speed of light. As something gets heavier, it needs more of a push to accelerate it. But at the speed of light, its mass becomes traveling faster than the speed of light is not an engineering that, according to Einstein’s theory, cannot be done. In 1908, Hermann Minkowski, Einstein’s professor, gave a speech entitled “Space and Time,” in which he set out what we now call the geometric interpretation of the special theory of relativity. In this speech, Minkowski said, “Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.” With Minkowski’s interpretation, Einstein realized that we live in a fourdimensional universe. 30
Thinkers as far back as Gottfried Leibniz in the 17 th century had realized that the universe encompassed three spatial dimensions and time, but they claimed that there was a fundamental difference between space and time. Minkowski realized that the universe that Einstein gives us weaves space and time together into a single fabric, a fabric whose pattern will appear different to different observers moving at different speeds but which is the reality underlying all of the different observations. We live not in Newton’s three- absolute time; instead, we live in a single four-dimensional space-time. Each of us experiences this reality differently, but through the equations in the theory of relativity, we can calculate the underlying truth about the unobservable four-dimensional space-time manifold. The works of Pablo Picasso and, later, Kurt Vonnegut are attempts to make sense of what the universe looks like from the new perspective given to us by the theory of relativity. Eleven years later, Einstein would rework this theory, expanding it and extending it to challenge our picture of reality in even more radical ways. Einstein, , part I.
