Imagine that you are located on earth while a spaceship travels from earth to the star vega at constant velocity of 0.8c. the following items describe quantities that, according to einstein’s special theory of relativity, would be either larger (or longer), smaller (or shorter), or the same as their rest values. (note that by "rest value," we mean the value you would find if both you and the spaceship were at rest on earth.) match each item to the correct category.
