“The Big Bang” is the idea that the universe began as “just a single point,” then expanded and stretched to grow as large as it is right now—and it is still stretching! This radical new theory on the ...

Through ten chapters, the book traces astronomy from its roots in ancient ideas of cosmology and geocentrism, through the Renaissance, the Newtonian Revolution, and the dawn of modern physics. It ...

For decades, scientists have relied on a popular idea referred to as cosmic inflation to explain how the universe began and why it looks the way it does today. This theory suggests the universe ...

A new cosmological theory is challenging the traditional Big Bang model by proposing that the universe originated from a gravitational collapse that created a black hole. According to a study ...

One of the greatest unsolved problems in physics concerns unifying quantum mechanics and general relativity—two equally successful theories that infamously don’t get along. And the latest attempt to ...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...

For several decades, the Standard Model of Elementary Particles (SM) (Fig. 1) has provided a broadly accepted description of our Universe. On the other hand, there has been strong evidence that the ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians ...

Imagine we had somehow filmed the whole history of the universe and you could play the movie in reverse. It would start off much as things stand today: a vast and elegant web of galaxies and nebulae.

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...
