Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and dark energy on cosmic evolution.

Astronomers working with data from the Hobby-Eberly Telescope Dark Energy Experiment, known as HETDEX, say they have produced one of the largest and sharpest three-dimensional maps to date of ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

The universe doesn’t revolve around Kitt Peak, but the observatory southwest of Tucson is at the center of what could be the biggest breakthrough in the study of the cosmos in decades. Using an ...

Piers Morgan was left speechless on his Uncensored YouTube show as guest, financial executive Eric Weinstein, claimed he knew the real reason physicist Stephen Hawking was on Jeffrey Epstein ’s island ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the universe’s accelerating expansion. Now a new wave of data is forcing ...

What was your favorite toy growing up? This paradox claims that memory—and every other one—is just a random fluctuation.

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, ...
