A new study suggests the universe might collapse in 20 billion years. This challenges the idea of endless expansion. Scientists analyzed data from the Dark Energy Survey and Dark Energy Spectroscopic Instrument. They propose dark energy may not be constant. Gravity could eventually reverse expansion, leading to a Big Crunch. This is the opposite of the Big Bang.
