Space Time curvature Review and Understanding
Space-Time Review
Space time is like a manifold
woven of space and time, When any terrestrial body moves through it both space
and time are changed. Einstein said time is what we measure with clock. I would
not get to caught up in time it has an illusory nature. Time is the medium in
which everything happened. Space is the area or volume that matter and its
waves occupy. Time quantifies change. Since all matter in the universe
vibrates, it's state and position are always changing. Time is the measure of those
changes. Without matter both space and time would be meaningless and would not
exist.
According to Einstein Gravity is not a force
but a curvature in space-time.
Space-Time is a four dimensional model that combines three Dimensions of Space and one Dimension of Time into a singal entity called space-Time.Equation of relativity tells us that both the space and time coordinates of any event fused together in order to accurately describe. Because space consists of 3 dimensions, and time is 1-dimensional, space-time must, therefore, be a 4-dimensional object. It is believed to be a 'continuum' because so far as we know, there are no missing points in space or instants in time, and both can be subdivided without any apparent limit in size or duration.
