flag South Korean scientists, using DESI data, suggest dark energy is weakening, possibly leading to a Big Crunch, challenging current cosmological models.

flag New analysis of supernova data by a South Korean team, supported by findings from the DESI instrument, suggests dark energy—thought to drive the universe’s accelerating expansion—may be weakening. flag This challenges the standard cosmological model and raises the possibility the universe could eventually collapse in a Big Crunch, rather than expand forever or end in a Big Rip. flag While some scientists call the results revolutionary, others remain skeptical, citing uncertainties in adjusting supernova brightness for galaxy age. flag The true nature of dark energy and the universe’s fate remain uncertain.
