AdS/CFT: a deep duality
A post qualitatively explaining the main ideas behind the AdS/CFT correspondence. The breakthroughs in theoretical physics due to the theory are outlined along with the consequences for how we view our universe.

A System of Plenty
Today we bring together black holes and exoplanets to fantasise over the ultimate solar system with a dark twist.
Black Holes: #3 The Second Horizon
A continuation in the series on Black Holes, examining the inner horizon known as the Cauchy Horizon and its implications on space and time.
A Quantum Fluctuation
How quantum fluctuations in the early universe acted as seeds of structure and eventually led to the formation of the galaxies that we see today.
Contains fairly complex ideas and references to previous posts.
Special Relativity & the Nature of Time
An extended piece on the nature of time as a result of the theory of Special Relativity.
What is Quantum Field Theory?
A brief, purely discursive, post explaining the motivations for and success of Quantum Field Theory.
The Long Voyage
To mark their 40th anniversary, we tell the story of the Voyager missions. Twin spacecrafts launched in 1977 that have travelled further than any human object, out into the depths of interstellar space and are still reaching for the stars.
What is a Group?
Today we will present the basics of Group Theory. Group Theory is essential to theoretical physics as it examines the symmetries of nature to uncover fundamental connections and patterns within the universe.
What’s the ‘Proper Time’?
Revisiting the theme of time we explain the geometry of spacetime and explore the special quantity known as ‘proper time’. A qualitative post which includes the use of simple graphs.
Feeling Futuristic
Today I’ll be looking forward just over a decade and pulling out what are believed to be 10 of the biggest scientific advancements of tomorrow. Hold on tight things are about to get exciting.
