Particle physics by CMS experiment at DESY on Instagram: "🌌 1/10 – Sofia’s takeaways from DESY✨
Sofia was an intern at DESY from September to December 2025, where she worked on particle and astroparticle physics, mentored by @simrangurdasani
“I learnt about the concept of dark matter and how it makes up about 27% of the Universe, while only around 5% is built from the matter we can actually see (with the rest being dark energy). It’s often described as the invisible glue of the Universe — because unlike visible matter, it doesn’t interact with light and can’t absorb, reflect, or emit it.
So then… how do we know it exists?
The first ideas of dark matter appeared in the 1930s, when astronomer Fritz Zwicky noticed that galaxies in the Coma Cluster were moving too fast to be held together by visible matter alone. Later, in the 1970s, Vera Rubin’s work on the motion of stars in spiral galaxies revealed this same ‘missing matter’. And that’s how the concept of dark matter became widely accepted — even though we still don’t know what it’s made of!”
