Someday, the universe will end. As for how—be it the Big Freeze, the Big Rip, the Big Crunch, or even the Big Slurp—the possibilities are numerous and delightful. That said, the general consensus is that an accelerated expansion of the universe will end in a Big Freeze. And the latest research argues that a recent challenge to this understanding isn’t supported. A study published yesterday in Monthly Notices of the Royal Astronomical Society (MNRAS) reinforces support for the theory that our universe’s expansion is still accelerating. The new results directly challenge a paper from November last year, published in the same journal, which argued that flaws in popular measurement methods mischaracterized the deceleration of the universe’s expansion. The latest work asserts that there is “no flaw in the widely accepted theory,” the team behind the new study said in a statement. “The previous and well-accepted measurements were, in fact, fine, and our current understanding of the fate of the universe remains robust,” Phil Wiseman, the study’s lead author and an astrophysicist at the University of Southampton in the U.K., added.
This doesn’t mean we’ve decisively solved the many mysteries of the cosmos. Even if the universe’s expansion rate is accelerating, scientists have yet to fully understand the true nature of dark energy, the hypothetical force said to drive this expansion.
