Astronomers find evidence of cosmic inflation, gravitational waves and the Big Bang
In the immediate aftermath of the Big Bang it's believed the universe grew at an exponential rate in what is known as cosmic inflation. Well, the first solid evidence of this growth, which would explain the uniform structure of the universe, has been discovered in the form of a curl in the cosmic background radiation left by the Big Bang itself. The "curl," known as B-mode polarization, is believed to be caused by gravitational waves produced during the first fractions of a second of existence. As it expanded and nothingness filled with extremely high-energy particles, waves of gravitational forces would have propagated, not unlike ripples on a pond, leaving behind scars.
