Half the matter in the universe was missing – we found it hiding in the cosmos

Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.

Pairing lasers with microwaves makes mind-bogglingly accurate electronic clocks – a potential boon for GPS, cell phones and radar

Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.

Why do astronomers believe in dark matter?

Why do astronomers believe there's dark matter when it cannot be directly detected? Let's look at the evidence, and see what dark matter's presence means for our universe.

Curious Kids: Where do black holes lead to?

The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
The existence of wormholes is not forbidden by our current theories of the universe. So we can say that they do exist in theory. Marcella Cheng/The Conversation NY-BD-CC

Curious Kids: How do wormholes work?

A wormhole is like a tunnel connecting two places in space. They would be incredibly useful and are great for science-fiction stories. The problem is we haven't found any evidence of them existing.
