Yeah, timelines spot on. Young's double-slit in 1801 kicked off the wave-party for light. Dark matter hints go way back, but Vera Rubin's galaxy rotation curves in the seventies really nailed it down. Dark energy's the baby of the bunch - Perlmutter, Schmidt, and Riess's supernova teams dropping the acceleration bomb in '98/'99. As for that late-2025 paper: you're likely thinking of the Yonsei University one (Young-Wook Lee and team) from around November 2025, with follow-up buzz into December. They argue Type Ia supernovae aren't perfect standard candles because progenitor age affects brightness - older stars in distant (earlier) universe make far-off ones look dimmer than they should, mimicking acceleration. Correct for that bias, and poof - no need for constant dark energy; expansion might even be slowing already. It's bold, directly poking at Perlmutter's Nobel-winning work. But the community's pushing back hard - some say the data's flawed; others point out independent confirmations of the age effect (or lack thereof). Nobel folks have dismissed similar claims before. If it holds up with upcoming surveys like Vera Rubin Observatory or more DESI data? Game-changer. Bigger than evolving dark energy hints, because it could ditch the whole acceleration story. But right now, it's controversial as hell. Worth watching though. Makes you wonder what we'll know next year.
