# 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.

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.

An extended piece on the nature of time as a result of the theory of Special Relativity.

A brief, purely discursive, post explaining the motivations for and success of Quantum Field Theory.

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.

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.

A post which explains the five main laws which govern the quantum world. The post is purely qualitative and requires no use of mathematics.

A brief introduction to the biggest contender for a unified theory – a 2000 word introduction to string theory requiring no mathematics.

A brief introduction to the weird world of quantum computing. Learn how a small number of quibits can quickly transform into something wonderfully complex.

A brief introduction to the increasingly important world of neutrino physics. The little stuff is shy, mysterious but fundamentally the material from which reality is constructed. Shall we?
