Scientists from Cornell University, Shanghai Jiao Tong University, and other academic institutions have calculated a likely timeline for the end of the universe. According to the study, the universe will ultimately contract and collapse back into a single point in approximately 33.3 billion years in a phenomenon dubbed the “Big Crunch.”
Researchers analyzing cosmic timelines have produced a new calculation for the ultimate fate of the universe. Drawing on findings from experts at Cornell University, Shanghai Jiao Tong University, and other academic institutions, the study outlines a trajectory where cosmic expansion eventually reverses, drawing all matter, space, and time back into a singular point.
Understanding the Big Crunch Mechanism
The newly calculated phenomenon is called the “Big Crunch,” functioning as the inverse of the Big Bang theory that established the universe from a singular point. According to the study, the universe will continue to stretch like a rubber band
until the elastic force surpasses the strength of cosmic expansion itself, pulling everything back inward.
This dynamic centers on dark energy, a mysterious force comprising roughly 70 percent of the known universe. While scientists have long treated dark energy as a constant driving mechanism behind expansion, recent discoveries suggest the force may have limits. New theoretical models indicate expansion will continue at a progressively decreasing rate until it reaches a peak size roughly 69 percent larger than its current dimensions, at which point a gradual contraction will commence.
Projected Timelines for Earth and the Cosmos
Given that the universe has reached an age of 13.8 billion years, the team calculates that the Big Crunch will take place in approximately 33.3 billion years. This leaves Earth and other planets with roughly 20 billion years before complete annihilation.
However, terrestrial existence will conclude long before the universe begins its final contraction. Separate scientific predictions note that within 20 billion years, the sun will burn out and our galaxy will collide with the neighboring Andromeda galaxy.
