Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, ...

In the blink of an eye after the Big Bang, the universe could have birthed strange new stars and black holes.

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be ...

Scientists at Tel Aviv University have developed a new way to investigate dark matter by studying faint radio waves from the Universe’s earliest era, known as the cosmic dark ages. Their research ...

The Universe may not have begun with a Big Bang, but instead with a Big Bounce, according to a new theory about how the ...

Physicists agree that an awful lot went on in the first few seconds after the Big Bang, a lot of it in incomprehensibly tiny ...

A remarkable new study challenges the findings of Nobel Prize winning research into how our universe has changed over time.

A new study suggests that during a potential phase of primordial matter domination, particle interactions may have led to the formation of the universe’s first compact cosmic objects. Less than a ...

Cosmologists have traced the Big Bang’s earliest moments with great care, from the explosive inflation that set spacetime in motion to the period of newborn atomic nuclei known as primordial ...
