Dark matter tracks could give earliest view of Universe

Researchers have come up with a way to glimpse the infant Universe by decoding the earliest ripples in its light.

The trick is to tell the difference between 21cm waves from our galaxy and those from distant, ancient sources.

The fact that "dark matter" moved faster than normal matter in the early Universe should help amplify the distant signal, they report in Nature.

That could yield a look at the Universe when it was just 1% of its current age.
