This Light is a Different Kind of Invisible
Dark matter's most famous trait is its inability to interact with light, the particle version of which we call "photons". But in their attempts to figure out exactly what dark matter is, some scientists have proposed "dark photons".

Does Antimatter Fall?
In September 2023, a group of scientists from CERN published the first results from the ALPHA-g experiment, which seeks to figure out how antimatter responds to the force of gravity. Does it fall like regular matter? Does it not interact...

How To Detect a Neutrino
Why is there something rather than nothing? Well the answer may be found in the weakest particle in the universe: the neutrino. For over half a century Fermilab has been the premier particle accelerator facility of the United States and...

Does Antimatter Explain Why There's Something Rather Than Nothing?
The most precious substance in our universe is not gold, nor oil. It’s not even printer ink. It’s antimatter. But it’s worth every penny of it’s very high cost, because it may hold the answer to the question of why anything exists in our...

The Unreasonable Efficiency of Black Holes
This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions...

5 Baffling Mysteries About the Universe
At the beginning of the 20th century, many scientists thought that we had learned all there was to know about physics. The problem is, the better we get at measuring things and building models of our universe, the more we discover that...

TED-ED: How cosmic rays help us understand the universe - Veronica Bindi
We only know 4% of what the universe is made up of. Can we also know what lies beyond our galaxy ... and if there are undiscovered forms of matter? Luckily, we have space messengers - cosmic rays - that bring us physical data from parts...

TED-Ed: What happened to antimatter? - Rolf Landua
Particles come in pairs, which is why there should be an equal amount of matter and antimatter in the universe. Yet, scientists have not been able to detect any in the visible universe. Where is this missing antimatter? CERN scientist...
