Olbers’ Paradox
Olbers’ Paradox asks: if the Universe is infinite, and if there are stars (or galaxies) throughout it, why is the sky dark? Surely, if we look in any direction in the sky, that sightline will, eventually, land on a star. Common sense, therefore, tells us that everywhere we look, the sky should be as bright as the Sun, constantly aglow.

Another Paradox Resolved
The reason the Universe can be glowing all around us but still look dark comes down to the physics of light in an expanding universe. When space expands, and the distance between objects grows, the light passing between those things gets stretched out, shifting the light to lower frequencies on t...
