What is space time fabric?
In: 5
Space time is sometimes referred to as “block time” or “block universe” . This is due to its description of space-time as an unchanging four-dimensional “block”, as opposed to the view of the world as a three-dimensional space modulated by the passage of time. Any point in time and space throughout the universe since the big bang can be referenced with coordinates with this model. We can visualise it as a literal block like a cube.
The more imaginative writer can easily extend ths visual metaphor to being some sort of fabric.
