Universe's expansion rate refined using supernova 'twins' ⚡ экспресс
Original: ""SNe Ia twins" in the Hubble flow, and the determination of H0"
The 'twin' method refined the universe's expansion rate and deepened the mystery of the 'Hubble tension'.

Cosmic dust was throwing astronomers off like fog on a winding road. Twin supernovae helped wipe the headlights clear, revealing that the universe is racing outward faster than we thought. It confirms that something weird is going on out there—and our physics textbooks might need a rewrite.
🎯 It was precisely with type Ia supernovae that the accelerating expansion of the universe was discovered in 1998—a Nobel Prize-winning breakthrough.
🎬 Confirmation of the Hubble tension makes sci-fi scenarios where physical laws evolve just a little less fictional.
H_0 \approx 72.4 \ \text{km/s/Mpc}
The Hubble constant indicates how fast the recession velocity of galaxies increases with distance.
