The Universe Has Been Expanding Since the Big Bang. Just Not How We Thought.
Season 11
Episode 32
Last year, DESI made headlines when its map of the Universe suggested dark energy, the force driving cosmic expansion, might not be constant. Now, the Dark Energy Survey (DES) has released its final results. Do they confirm DESI’s findings? More importantly, why are different scientific studies far more powerful together than alone? The answer gets to the heart of how science works.
