Neutrinos are the most abundant particles in the universe with mass.

They are a type of fundamental #particle, which means they don’t break down into smaller constituents, and are therefore very small and light. In fact, they are the lightest of all subatomic particles that have mass.

Neutrinos also don’t have a charge.

As a result, only very rarely do neutrinos interact with with other matter. Trillions of neutrinos travelling through #space will have passed through your body since you started reading this text.

In February 2023, a cosmic particle detector housed deep in the Mediterranean Sea recorded the arrival of a #neutrino with approximately 20 to 30 times more energy than any other neutrino documented previously.

Labelled KM3-230213A, the particle had a calculated energy of 220 petaelectronvolts (PeV), far greater than the 10 PeV of the previously most energetic neutrino.

The finding generated a lot of excitement among physicists, but raised also many questions.

The top quark isn’t a loner after all: “toponium” is real! The top quark is the most massive, shortest lived particle of all. But it isn't always a "bare quark" that just decays; the LHC just revealed that the bound state of "toponium" is real! bigthink.com/starts-with-... #physics #particle #top

Big ThinkThe top quark isn't a loner after all: "toponium" is real!Can the top quark, the short-lived particle of all, bind with anything else? Yes it can! New results at the LHC demonstrate toponium exists.

InstagramNerd Snacks by @science on Instagram: "Physicists just pulled off something mind-bending: they created a particle of light that exists in 37 dimensions at once, smashing through the boundaries of both classical physics and our everyday intuition. Using a fiber-based “light processor” and a quantum trick called the Greenberger–Horne–Zeilinger (GHZ) paradox, the international team entangled photons across 37 different “contexts”—far beyond the usual three dimensions we live in. 💡 The experiment puts local realism—the comforting idea that things only happen because of immediate, local causes—on the ropes. Instead, quantum mechanics says particles can exist in many states at once, and only “decide” what they are when you measure them. In this quantum paradox, the usual rules break down, leading to results as strange as math saying 1 = -1. Scientists describe this as the strongest real-world evidence yet that the universe plays by bizarre, nonlocal rules. 🤯 Encoding light in 37 dimensions isn’t just a party trick: it could supercharge quantum computing and create ultra-secure communication networks, with far more information processed and protected at once than any classical system could manage. If this is just the tip of the iceberg, the quantum world could hold even wilder surprises, forcing us to rethink what’s possible both in technology and in the very nature of reality itself. 🚀 Click the link in bio for more great stories sent to your inbox!"11K likes, 297 comments - nerdsnacks.io on June 19, 2025: "Physicists just pulled off something mind-bending: they created a particle of light that exists in 37 dimensions at once, smashing through the boundaries of both classical physics and our everyday intuition.
