A faint glow left behind from a time when everything was closer, hotter, and just beginning to cool.We’ll drift back to the early universe, when light first became free to travel. When space was young. When the patterns we see today were only soft variations in temperature.There is no need to grasp every detail. Only imagine a quiet afterglow, still reaching us after billions of years.As you listen, let the idea feel steady and reassuring. The universe has been unfolding slowly for a very long time.And tonight, you can rest beneath its oldest light. Hosted on Acast. See acast.com/privacy for more information.
