Dark energy is supposed to make up roughly 70% of the universe.

But what if it's not really an explanation at all?

Recent cosmological measurements are raising new questions about one of the biggest ideas in modern physics. Is dark energy actually changing over time? Or are we seeing the effects of statistical artifacts, data selection, or measurement error?

In this episode of Science in Perspective, we explore:
• What dark energy actually is (and isn't)
• Why some physicists think the standard model of cosmology may be under pressure
• The role of p-values and p-hacking in scientific discovery
• Why many scientific concepts begin as placeholders before becoming explanations
• What these new results might mean for our understanding of the universe
