Space-time ripples hint at physics beyond the big bang
by Lisa Grossman
Slivers of a second after the universe was born, IT ballooned exponentially in the blink of an eye. This vision of cosmic expansion, called inflation, got a big boost last week with the announcement of the first sighting of primordial gravitational waves, ripples in space-time linked to the universe’s rapid growth spurt.
The findings – reported by the team that ran the BICEP2 experiment at the South Pole – are already helping physicists sort through the mountain of theories for how inflation happened (see our video of gravitational waves explained with a towel and apple).
But there are a few wrinkles, including the fact that hints of the waves seem much more pronounced than they should be, according to previous observations of the early universe. Resolving the discrepancies – perhaps using results due out later this year from the Planck space telescope – might give a glimpse of physics from before the big bang. Or it might mean inflation is out, and that we actually have the first whiff of evidence for string theory…
