I follow the development of time travel theory (a relativity theory subfield). A working time machine may be built in the foreseeable future!

Reversible dynamics with closed time-like curves and freedom of choice: arxiv.org/abs/2001.02511

Reversible dynamics with closed time-like curves and freedom of choice

The theory of general relativity predicts the existence of closed time-like curves (CTCs), which theoretically would allow an observer to travel back in time and interact with their past self....

Life on a closed timelike curve: arxiv.org/abs/2405.18640

Life on a closed timelike curve

We study the internal dynamics of a hypothetical spaceship traveling on a close timelike curve in an axially symmetric universe. We choose the curve so that the generator of evolution in proper...

Quantum mechanics near closed timelike lines

The methods of the quantum theory of computation are used to analyze the physics of closed timelike lines. This is dominated, even at the macroscopic level, by quantum mechanics. In classical physics...

A time machine for free fall into the past: arxiv.org/abs/1803.08214

A time machine for free fall into the past

Inspired by some recent works of Tippett-Tsang and Mallary-Khanna-Price, we present a new spacetime model containing closed timelike curves (CTCs). This model is obtained postulating an ad hoc...

Closed Timelike Curves and "Effective" Superluminal Travel with Naked Line Singularities: arxiv.org/abs/1708.09505

We examine closed timelike curves (CTCs) and "effective" superluminal travel in a spacetime containing naked line singularities, which we call "wires". Each wire may be straight-line singularity...

The quantum mechanics of time travel through post-selected teleportation

This paper discusses the quantum mechanics of closed timelike curves (CTC) and of other potential methods for time travel. We analyze a specific proposal for such quantum time travel, the quantum...

New light on time machines: Against the chronology protection conjecture

I construct a spacetime with closed timelike curves and without closed causal geodesics. There is a noncompactly generated Cauchy horizon separating the region with closed timelike curves from that...

Juan Maldacena on traversable (including humanly traversable!) wormholes; no negative density energy needed: arxiv.org/abs/1807.04726 arxiv.org/abs/2008.06618

Traversable wormholes in four dimensions

We present a wormhole solution in four dimensions. It is a solution of an Einstein Maxwell theory plus charged massless fermions. The fermions give rise to a negative Casimir-like energy, which...

Open-Endedness is Essential for Artificial Superhuman Intelligence

In recent years there has been a tremendous surge in the general capabilities of AI systems, mainly fuelled by training foundation models on internetscale data. Nevertheless, the creation of...

We give an introduction to the QBist interpretation of quantum mechanics. We note that it removes the paradoxes, conundra, and pseudo-problems that have plagued quantum foundations for the past...

Chemically induced reprogramming to reverse cellular aging - PubMed

A hallmark of eukaryotic aging is a loss of epigenetic information, a process that can be reversed. We have previously shown that the ectopic induction of the Yamanaka factors OCT4, SOX2, and KLF4...
