The latest cosmological research draws surprising conclusions through dark energy observation data:The overall lifespan of the universe is only about 33.3 billion years, breaking the previous inherent knowledge that the universe will expand infinitely and exist forever.. Researchers from the University of New Hampshire and other institutions in the United States published a paper in the Journal of Cosmology and Astrophysics pointing out that by analyzing the latest observational data from the Dark Energy Survey (DES) and the Dark Energy Spectroradiometer (DESI), the state equation parameter of dark energy, w≠-1, is not a constant cosmological constant as traditionally believed.
The research team used the best-fitting model to simulate the future of the universe.The results show that the overall lifespan of the universe is only about 33.3 billion years, which brings new changes to the traditional understanding that "the universe will continue to expand for trillions of years."
Since the Big Bang, the universe has existed for about 13.8 billion years, which means that we may have gone through about one-third of the history of the universe.
According to the derivation trajectory, the universe will continue to expand for a long time, stop expanding after reaching the peak volume, and then gradually shrink inward under the influence of gravity, and finally return to the high-density singularity in the form of a big collapse, forming an evolutionary closed loop opposite to the Big Bang.
Of course, for humans, this time scale is still far away, so there is no need to worry.After all, the sun will enter the red giant stage in about 5 billion years. By then, the ecology of the solar system will no longer exist, and human civilization will not be able to experience the evolution of the end of the universe..
