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.
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.
More than 70% of the Universe is made of ‘dark energy’, the mysterious stuff even stranger than dark matter.

Today on the podcast, we explore what we know about dark energy, believed to be responsible for the acceleration of the expansion of the Universe.
A recent experiment with atomic nuclei is hard to square with our current understanding of physics.
From the subatomic to the cosmic, don't think for a second that we're at the end of scientific history.
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
The Princeton cosmologist helped pioneer our current model of the universe and began a whole new branch of physics.
Maps of the long filaments of gas that hold the universe together may one day help us trace and unveil '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.
New research does away with dark matter by putting 'entropy', a measure of disorder, at the heart of the universe.
New research suggests we may be able to forget about dark matter if we tweak the laws of gravity according to imaginary bubbles in space.
A new collider at CERN could push particle physics deep into an unexplored microscopic realm.
Forget about dark matter and dark energy, new research suggests that the existence of 'dark fluid' may solve some of the biggest mysteries in physics.
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.
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.
Exactly 99 years after Einstein's theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.
Signals from the first stars to form in the universe have been picked up by a table-sized detector in a west Australian desert. The find also hints at an early interaction with dark matter.
New radio technology has managed to detect the first light in the universe.
Controversial new study challenges contemporary thinking about what the universe is made of.
Deep underground, scientists research subatomic particles from space in a bid to understand the building blocks of our universe.
