Big Bang Theory: The latest science and discoveries

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead formed inside a colossal black hole.

While headlines around the world claimed that these galaxies were "breaking" our understanding of the Big Bang, the truth is much more nuanced — and much more interesting.

It's a fun question to tackle because it lets us dig into the messy, complicated, beautiful process of galaxy formation.

We see these galaxies as they were over 13.45 billion years ago, just between 330 and 350 million years after the Big Bang.

We all know the universe contains a vast array of elements, ranging from light gases, such as helium, to heavy metals, like lead. But where did all of the elements come from?

A new method to detect Baryon Acoustic Oscillations in the universe could help measure cosmic distances more accurately.

Astronomer Carl Sagan once said that humanity is "made of star stuff." In a new video, astrophysicist Suzanna Randall explains what that actually means and where the elements in our body come from.

Thanks to the James Webb Space Telescope, scientists have begun getting the goods on Earendel, the most distant star ever detected.

The coming Square Kilometre Array could shed light on mysterious dark matter, revealing the role it played in the formation of the universe's first galaxies.
