A new result from the MicroBooNE neutrino experiment has dashed hopes for a neat resolution to several puzzles for physicists.
If God could break the laws of physics, why haven’t we seen any evidence of the laws ever being broken in the universe?
Many societies in Africa still draw heavily on their traditional beliefs and cultural heritage. Therefore it’s important to take these into consideration when psychology is taught and practised.
These results might lead us to revise our understanding of how galaxies stop forming their stars.
A collaboration between Australian and German scientists gives an unrivalled view of the structure of the Universe.
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.
The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
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 study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
The 2019 Nobel Prize in Physics went to a cosmologist who helped unlock the secrets of the Big Bang’s aftermath, and two astronomers who found a “hot Jupiter” orbiting a nearby star.
The Princeton cosmologist helped pioneer our current model of the universe and began a whole new branch of physics.
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.
If we want an improved theory of particle physics, understanding neutrino masses is key.
A spinning black hole is pumping vast amounts of energy back into the surrounding universe, but something is causing the jets that transport that energy to wobble very rapidly.
Astronomers say they have “seen what we thought was unseeable” in releasing the first image of a supermassive black hole. So how did we get to this historic observation?
Apollo 8 was the moment that humanity realised a dream conceived in our cultural imagination over two millennia ago.
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.
Astronomers are voting to rename one of the laws of physics. The voting may have far-reaching effects leading to renaming of other laws and giving ‘forgotten’ scientists due credit.

A podcast all about nothing. From the importance of doing nothing to the ill-effects of time spent in solitary confinement and what nothing means in space.
