A technical overview of spacetime singularities from the Penrose-Hawking theorems to the limits of stellar collapse.

Examine how LQG, string theory, and asymptotic safety resolve the infinite curvature of the classical manifold.

String theory replaces point particles with one-dimensional strings, providing a description for gravity.

This article examines the theory's development, its concrete results, and the landscape problem it has not resolved.

What is renormalisation, and why does it work for electromagnetism, the strong force and the weak force but fail completely when applied to gravity?

Quantum mechanics predicts experimental results to eleven significant figures. Yet it does not explain what happens when a quantum system is observed. This article examines the measurement problem and why the problem has direct consequences for any theory of quantum gravity.

Modern deep learning violated classical statistical theories by achieving exceptional generalisation despite overparameterization, raising critical questions about theoretical foundations and the underlying mechanics of neural networks.

The most successful theory in the history of science has a problem. The Standard Model works too well to abandon and not well enough to trust completely.
