Data from dark-energy observatories indicate universe may ‘end in a big crunch’ at 33 billion years old
Credit: Unsplash/CC0 Public Domain The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size…
Information could be a fundamental part of the universe, and may explain dark energy and dark matter
Credit: CC0 Public Domain For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum…
Is dark energy evolving? Astrophysicists consider the possibilities
A new study, based on years of precise data from telescopes such as the Dark Energy Survey in Chile, above, suggests that the mysterious force known as dark energy may…
Growing evidence for evolving dark energy could inspire a new model of the universe
The Big Bang started around 13.8 billion years ago. Credit: NASA The birth, growth and future of our universe are eternally fascinating. In the last decades, telescopes have been able…

Dark energy may not be constant—this discovery could undermine our entire model of cosmological history
by Bernard J.T. Jones, Licia Verde, Vicent J. Martínez and Virginia L Trimble, The Conversation The Cosmic Inventory: the different components of the universe derived from the Planck Satellite observations…
A simulated universe works better when dark energy changes over time
Supercomputer simulations tested the Standard Cosmological Model against a Dynamical Dark Energy Model to see which one better matched new DESI data. Credit: ALCF Visualization and Data Analytics Team and…
Latest dark energy survey data suggest possible variations in dark energy over time
The U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile, a Program of NSF NOIRLab. The Blanco is home to the 570-megapixel…
Release of Type Ia supernovae data may hold key to the history of the universe
