Scientists propose that gravitational waves shaped the universe. Their model challenges inflation theory. How exactly did the ...

The true “informational age” of the cosmos may be 62 billion years, not just the 13.8 billion years of our current expansion.

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole ...

As the study of the universe evolves and the data sets get larger and more complex, a new breakthrough means researchers can ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if ...

Einstein’s version of dark energy is known as the cosmological constant. It implies a fixed amount of dark energy in each ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

One method involves analyzing Cosmic Microwave Background (CMB) radiation to gain insight into the early universe—light that remained after the Big Bang just 380,000 years later. This method relies on ...

There is a new Physics model that challenges the standard Big Bang theory. By definition, “ The Big Bang ” is how astronomers explain the way the universe began. “The Big Bang” is the idea that the ...

Astronomers use many methods to determine this number, including gravitational lensing, the universe’s expansion rate, and more.
