Cosmic Concepts
Frozen in Time? Most information from outer space reaches us at the speed of light and this governs our understanding of time and evolution in the cosmos. When we observe the Universe, we are 'looking back in time': we see the Universe as it was, not how it is. This is actually very helpful as we seek to discern and understand cosmic history and how the Universe has changed since earlier times.
