Big Bang Theory: The latest science and discoveries

Inside the latest issue of All About Space is our complete guide to exoplanets where we peer into the most extreme alien worlds and hunt for Earth 2.0.

Does the simulation hypothesis offer a compelling argument, or is it just interesting food for thought? Let's find out.

The earliest and most momentous epoch in the history of the universe released a flood of gravitational waves, tiny ripples in the fabric of space-time.

Astrophysicists say our universe might be shaped like a three-dimensional donut, meaning you could point a spaceship in one direction and eventually return to where you started.

Why is the universe the way it is? Over the years, scientists have explored many ways to explain the cosmos, leading to some crazy-sounding ideas.
