Main Question or Discussion Point
Can someone tell what are dimensions and what does the line "Three diemsion space and one dimension time means". please.
The fact that space and time can be united into four dimensional spacetime is essential to the general theory of relativity, Einstein's theory of gravity. For further reading on relativity: http://math.ucr.edu/home/baez/physics/Administrivia/rel_booklist.htmlThe views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.
"Dimensions" indicate the extent of the universe...like if you were trying to set up a coordinate system to describe the universe. Our main model of how the universe works is that the universe is comprised of space and time. Matter and energy are things that reside in the universe...reside in the fabric of space and time.Caesar_Rahil said:Can someone tell what are dimensions and what does the line "Three diemsion space and one dimension time means". please.
