5 Ways the Universe Could End -

What will happen at the end of the universe? In this video, we explore five possible cosmic endings, including the Big Freeze, Big Rip, Big Crunch, Big Bounce, and vacuum decay, and examine how new DESI observations of dark energy could change our understanding of the universe’s ultimate fate. Could the cosmos fade away, collapse, or begin again?
