After 13.8 billion years, we just might know all the rest to come
Have you ever wondered how the Universe will end? In the far future, everything that we know, see, measure and perceive today will someday decay away, becoming something very different from what we know it as today. The Earth will cease to harbor life, the Sun will die, the galaxies will merge and recede, and eventually everything will fade to black. But beyond that, space itself will push everything apart, stellar remnants will get ejected, and even the most massive objects at all will decay into nothingness.
