Laniakea: Our home supercluster
Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of […]
How it Works: Quantum Computing
Quantum computing has the potential to solve some of the world’s most complex problems. So how are quantum computers different from the traditional computers we use today?
The Phantom Singularity | Space Time
Isaac Newton’s Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton’s equations. They don’t always accurately represent reality. Einstein’s General Theory of Relativity is a more complete theory of gravity. So does using the […]

The Elon Musk-Jeff Bezos Feud, Explained
Elon Musk and Jeff Bezos are in an epic feud that’s been raging for years. But it wasn’t always the case. In 2004, for example, the two titans had dinner together. Today, instead of passing ideas, they’re berating each other for the world to see. Here’s how things got so out of hand.
Why can’t some birds fly? – Gillian Gibb
Though the common ancestor of all modern birds could fly, many different bird species have independently lost their flight. Flight can have incredible benefits, especially for escaping predators, hunting and traveling long distances. But it also has high costs: consuming huge amounts of energy and limiting body size and weight. Gillian Gibb explores what makes […]

Why is our universe fine-tuned for life? | Brian Greene
At the heart of modern cosmology is a mystery: Why does our universe appear so exquisitely tuned to create the conditions necessary for life? In this tour de force tour of some of science’s biggest new discoveries, Brian Greene shows how the mind-boggling idea of a multiverse may hold the answer to the riddle.
Making sense of string theory | Brian Greene
In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein’s notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at […]
