What is space-time and space-time curvature?
I want to know more about space-time and space-time curvature.
Sure, I'd be happy to help. Space-time is the fabric of the universe that connects the three dimensions of space with time as the fourth dimension. According to Einstein's theory of relativity, massive objects like planets and stars exert a gravitational force, causing space and time to warp around them. This is known as space-time curvature.
