When a black hole evaporates, is the information about what fell in preserved or destroyed? #cosymorg #science #information_paradox

The information describing a volume of space may be entirely contained on its boundary surface. This article examines where that idea came from, what the AdS/CFT correspondence established, and what it implies about the nature of space and information. #cosymorg #science #holographic_principle

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. #cosymorg #science #singularities

Is spacetime smooth and continuous, or does it have a fundamental granular structure? This article examines the theoretical and experimental evidence for spacetime discreteness. #cosymorg #science

What if the failure of quantum gravity was never a problem with the theory but only with the method? What if gravity, at the highest energies, simply stops changing? #cosymorg #science #asymptoticsafety

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. #cosymorg #science #stringtheory

Loop quantum gravity suggests spacetime is not continuous but quantised, leading to new insights into black holes and the early universe. In the article, explore how far this idea goes and where it falls short. #cosymorg #science #LQG #BigBounce #SpinFoam #SpinNetworks

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

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. #cosymorg #science #QM

What is Planck length? How it emerges from fundamental constants, what it reveals about quantum gravity, and why physics breaks down at the smallest scales? #cosymorg #science #planck_length

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. #cosymorg #science #neural_network #computerscience

Does infinity exist, or is it a tool that mathematics use? Most people encounter infinity as a symbol ∞ and treat it as shorthand for something very large. In mathematics, this is not what infinity means. #cosymorg #science #infinity

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. #cosymorg #science #standardmodel
