🧵 Cosmological Simulations: How We Rebuild the Universe Inside a Computer What if you could rewind the universe… and then press play again? That’s exactly what cosmologists do— not with telescopes, but with supercomputers.

🧵 Does the Universe Have a Center? Instinctively, we imagine everything must have a center. Circles do. Explosions do. So it feels natural to ask: 👉 Where is the center of the universe? The answer is… unsettling.

🧵 Dark Energy: A Fatal Error… or New Physics? The universe is expanding. Not just expanding—but accelerating. Something is pushing galaxies apart faster and faster. We call it dark energy. But here’s the twist: 👉 It might be a huge mistake… or the biggest discovery in physics.

I know I only make posts about my papers, but I can't help not sharing that my second paper-- and my first paper as part of the DESI collaboration-- has just been published! You can find the paper here: www.aanda.org/articles/aa/...

I’m excited to share my first published paper: "Constraining cosmological parameters using void statistics from the SDSS survey", where we explore how cosmic voids can be used to constrain key cosmological parameters such as σ₈, Ωₘ, and H₀. 📄 Read the full article here: 🔗 doi.org/10.1051/0004...
