(CNN) — New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.

There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and ...

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

A new hypothesis known as the Quantum Memory Matrix (QMM) could help explain some of the biggest mysteries of the universe, including the Black Hole Information Paradox. The idea is that space-time ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And ...

Scientists propose that the entire universe might be spinning very slowly (0.002 rotations per billion years), which could explain why different methods of measuring cosmic expansion give conflicting ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

The cosmos is riddled with evidence that the universe began with an unfathomably rapid expansion — even faster than in traditional Big Bang theories — but scientists don’t know why it happened. A ...

Scientists have shared a new theory about how the universe might end, not by fading away slowly, but by collapsing in on itself in what they call a “reverse Big Bang.” The idea suggests that after ...

(Nanowerk News) In a new analysis, physicists provide the most precise picture yet of how neutrinos change ‘flavor’ as they travel through the cosmos. Neutrinos are fundamental particles of the ...
