I want to know the answer to the following question:
In Minkowski spacetime, how can distances in space be measured?
All the background I'm provided with is that "In this formalism, distances in space can be measured by how long light takes to travel that distance, e.g., a light-year is a measure of distance, and a meter is now defined in terms of how far light travels in a certain amount of time.". Is that enough to answer the question?
