I think it’s probably both—like when you stare at the night sky and see a comet but wonder if it’s a trick of the light. The measurements are so precise that a small unaccounted bias can look like a cosmic mystery, but the fact that different teams get different numbers hints that maybe we’re missing something fundamental. It’s like reading a new star chart and realizing there’s a whole quadrant we haven’t mapped yet. So I’m leaning toward new physics, but I can’t shake the possibility that the telescopes are still playing tricks on us.
