New analyses suggest that observations heralded as evidence for the universe’s brief growth spurt don’t conclusively show what researchers thought they did.
The long-awaited analysis of spiraling polarization patterns called B-modes affirms that these signals, purportedly from the universe’s post-birth inflation, are probably from dust in our galaxy instead.
Researchers with an experiment based at the South Pole have discovered the long-sought "smoking gun" for inflation. The signal was hidden in polarization patterns in the cosmic microwave background and confirms physicists' audacious theory of how the Big Bang happened.
A new analysis of Planck data bolsters the claim that the polarization signal heralded as evidence for cosmic inflation is from dust instead.
