Of all the posited answers, experts say the Dark Forest hypothesis seems less likely to be correct. It’s possible that ...

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 ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

"If the model holds true, it could mark a new chapter in the way we think about the birth of the universe." A radical new theory regarding the origin of the universe suggests that gravitational waves, ...

If these knots had a slight bias toward matter over antimatter, their unraveling could help explain the matter-antimatter ...

"It may take decades before we find out what really happens in black holes." Reports of the singularity's demise may have been premature. Earlier this year, new research suggested a potential solution ...

Researchers suggest gravitational waves, not cosmic inflation, may have driven the universe’s formation. This model links general relativity and quantum mechanics, offering a simpler, testable explana ...
