All matter will eventually be consumed by monstrous black holes, which in their turn will evaporate away into the dimmest glimmers of light. Space will expand ever outwards until even that dim ...

At the beginning of the Universe, within minutes of the Big Bang, space was filled with a hot, dense fog of ionized plasma. What little light there was wouldn't have penetrated this fog; photons would simply have scattered off the free electrons floating around, effectively making the Universe dark.
May 8, 2012 · The inside of the balloon is not a space where matter or photons propagate. Everything happens at the expanding surface. Thus the light the astronomers see from the Big Bang, the cosmic microwave background radiation is the light coming from everywhere on our point on this surface.
Oct 23, 2018 · Nothing exploded. But that doesn’t mean it wasn’t a busy and exciting event. The rush of inflation was a powerful outpouring of energy, which certainly included light. And yet, the energy...
The first moments after the Big Bang are literally hidden from us: the entire cosmos was too hot and dense for any light to pierce. However, signs of what happened then could be imprinted on the cosmic microwave background (CMB), a cold sea of light filling the modern universe.
When that material in space cooled down, it became a dust cloud that temporarily blocked some of the star’s light. Hubble’s unique ability to observe in ultraviolet light helped reveal the details of this dimming event and its aftermath.
