closed timelike curve

This example doesn't completely settle the question, because it has closed timelike curves.

Concepts that aid such understanding include the closed timelike curve.

A closed timelike curve is a circle in time.

"I know what a closed timelike curve is," Spinner said.

When there are no closed timelike curves, and are two different regions.

Therefore they have no hope of ruling out objectionable global features, such as closed timelike curves.

These objections to the existence of closed timelike curves are not universally accepted, however.

"Am I still in the closed timelike curve?"

In particular, frame dragging and closed timelike curves.

Spacetimes with closed timelike curves, for example, present severe interpretational difficulties.

Then, we either have null geodesic incompleteness, or closed timelike curves.

The chronology violating set is the set of points through which closed timelike curves pass.

We are going to build closed timelike curves...

Such a fold necessarily creates a closed timelike curve... So every electron was a miniature time machine.

"The creation of closed timelike curves."

The authors of Cauchy problem in spacetimes with closed timelike curves write:

Mathematically, the permissibility of time travel is represented by the existence of closed timelike curves.

As we move further outward, we can see that horizontal circles with larger radii are closed timelike curves.

He suggested that a finite cylinder might produce closed timelike curves if the rotation rate were fast enough but he did not prove this.

In a physical time loop (rarely seen in the media), the spacetime loops around to form several closed timelike curves.

Closed timelike curves, in which the world line of an object returns to its origin, arise from some exact solutions to the Einstein field equation.

A Closed Timelike Curve is a loop through space-time.'

It's hardly surprising that, whenever intelligent beings arise in such a universe, they will seek to use closed timelike curves to prevent their own extinction.

A rotating BTZ black hole admits closed timelike curves.

While this gets around the infinite acceleration problem, it still would lead to closed timelike curves (i.e., time travel) and causality violations.
