Planets in varying sizes orbiting around a bright central star in a purple-hued cosmos, where life persists.
There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life's final extinction will occur.
An image of a yellow and purple wave with an unclear origin.
Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.
