Time and Space

We live on one small planet, circling a star we call the Sun that is just one of 100 billion stars in the Milky Way galaxy. Our galaxy is just one among many millions in the Universe, which was born in the Big Bang, when time and space actually began. Space is what we move around in, in three dimensions, left and right, forwards and backwards, up and down. We can move around in space from one place to another. Time is less controllable. We seem to move forward through it – whether we like it or not. We cannot go back to the past, nor can we jump forward to the future. Scientists describe time as the fourth dimension, and combine time and space as one entity called spacetime. Featuring stunning photographs of historical scientific apparatus, experiments, and innovative 3-D models, Time Space is a unique and exciting introduction to the discoveries and research that have transformed our understanding of the universe.
