The debate was eventually settled after astronomersArno PenziasandRobert Wilsonobserved an unexpected radio-wavelength hiss coming from all directions in space in 1964, and notified the experimental physicistRobert Dicke, who identified it as evidence of the Big Bang. But this wa...
At first, there was neither time nor space. How and why everything got started is complicated—but we know that it all started with a bang. The explosion we’ve come to know as the big bang flung the energy in the newborn universe out in all directions. A...
