A bizarre neutrino that crashed into Earth in February 2023 is gaining no shortage of equally bizarre explanations.

An unexplained high-energy neutrino detected three years ago could be linked to a primordial black hole, perhaps one more even unusual than previously thought ...

The existence of these black holes could explain the recent detection of a high-energy neutrino by the KM3NeT detector. This ...

Strike a bell, and it rings with a pitch and a fading that tell you about the bell: its size, its shape, the metal it is made ...

Everything in the universe is made of just one single string. Can you imagine such a thing?This is a concept called "superstring theory." We often hear the name, but what exactly is a string? Not much ...

A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to ...

Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with. This way of looking at the cosmos could ...

If an "invisible dimension" much smaller than the thickness of a human hair actually existed, and it could simultaneously explain both dark matter (an unidentified substance that cannot be captured by ...

String theory is the idea that the building blocks of nature are made up of tiny, one-dimensional strings of energy rather than point particles. According to the theory, these strings vibrate at ...

Physicists aren’t known for playing fast and loose with the rules of reality. But when it comes to the concept of space, some take a remarkably permissive attitude. For most of us, it would seem there ...

String theory has been famously untestable for decades. This week the Economist reported that has changed, and the reason involves an extra dimension of space that might be just big enough to notice ...
