The earliest galaxies may have scrambled our reading of the Universe. A new study challenges the traditional interpretation of the cosmic microwave background, this fossil light from the Big Bang.

"This shocking result means that we now need to revisit the very foundations of everything we know about cosmology," said the reseachers.

For decades, the Big Bang has been the reigning champion in explaining the universe's origin. It's the moment, roughly 13.8 ...

The Big Bang theory has been the standard explanation of the universe's origin for decades. But one group now claims everything we think about the birth of the cosmos might be wrong.

Such a mission could let researchers peer through all the light there is, all the way back to the universe’s very first light ...
