What is space-time cube ArcGIS?

Space-time cubes show how phenomena change over time within geographic space. In a space-time cube, each cube represents a slice of time. For example, top cubes have newer timestamps. Whereas bottom cubes have older timestamps.

What is space-time cube analysis?

How do you visualize space-time?

Zitat von Youtube: A first idea would be to add small clocks to our diagram at each point of the grid.

How do you visualize the curvature of spacetime?

Zitat von Youtube: This is physically impossible to visualize. So don't worry when you find that you can't do it our brains. Can only comprehend three spatial dimensions and so the best we can do is to employ analogies.

What is a geodesic in spacetime?

In general relativity, a geodesic generalizes the notion of a „straight line“ to curved spacetime. Importantly, the world line of a particle free from all external, non-gravitational forces is a particular type of geodesic. In other words, a freely moving or falling particle always moves along a geodesic.
