Explain why time and space being combined into a single continuum makes something 4d
When time and space are combined into a single continuum, it creates a four-dimensional (4D) framework known as spacetime. This is because we are now considering not only the three spatial dimensions (length, width, and height) but also the dimension of time.
In spacetime, an event is identified by its position in both space and time. This means that an object's position is now described by four coordinates (x,y,z,t), where x, y, and z represent the object's spatial coordinates, and t represents the time coordinate.
By combining time and space into a single continuum, we can visualize events as points moving through spacetime, creating a dynamic and interconnected fabric in which the past, present, and future exist simultaneously. This understanding allows us to study the interactions between objects and how they influence each other over time.
Therefore, the combination of time and space into a single continuum results in a 4D framework that helps us perceive and analyze the world in a more holistic and comprehensive manner.
