The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, ...

The birth of the universe has been a question that has puzzled scientists for centuries. In a groundbreaking study published ...

The Universe might not exist forever. New observations by physicists indicate that it will one day reach its maximum size before beginning to contract. These results profoundly change our view ...

At the heart of the Milky Way, just 27,000 light-years from Earth, there is a supermassive black hole with a mass of more ...

If it is a galaxy, it would be the oldest known galaxy in the cosmos, but it could also be a brown dwarf or an early black hole.

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a finite timeline, new calculations suggest. Based on several recent dark energy ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

It will be a view unlike any other — completely invisible, exceptionally quiet and utterly transformative. Deep in the first moments of the Big Bang, the entire cosmos shook and rumbled. Those quakes ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

"Challenging long-held assumptions is essential to scientific progress." A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...
