A sensitive search for wormholes

Understand

The realm of strong classical gravity and perhaps even quantum gravity are waiting to be explored.

• In this letter we consider the recently detected triple system composed of two stars and a non-accreting black hole.
• Using published observations of this system we conduct the most sensitive test to date for whether the black hole is actually a wormhole by looking for orbital perturbations due to an object on the other side of the wormhole.
• The mass limit obtained on the perturber is $\sim4$ orders of magnitude better than for observations of S2 orbiting the supermassive black hole at Sgr A*.
