00:00For 50 years, scientists were stuck on one giant space mystery.
00:04How do red giant stars change their surface chemistry
00:07if a stable barrier deep inside should stop material from moving upward?
00:11Now, powerful supercomputers may have finally cracked the case.
00:15Astronomers created high-resolution 3D simulations
00:18and found the missing piece, stellar rotation.
00:21As stars like our sun grow into red giants,
00:24nuclear reactions deep inside change their chemistry.
00:27But for decades, no one could fully explain how those changes reached the surface.
00:32The new simulations show that when a star spins,
00:35it supercharges internal waves,
00:37helping them push material across the barrier far more effectively than anyone realized.
00:42In fact, mixing inside these rotating stars
00:45can happen more than 100 times faster than in stars that do not rotate.
00:49That is a huge discovery.
00:51It not only solves a mystery that has puzzled astronomers since the 1970s,
00:55but it also gives us a clearer picture of what may happen to our own sun billions of years from
01:00now.
01:01And none of this would have been possible
01:03without the latest generation of supercomputers pushing science to a whole new level.
