- A new study suggests that if wormholes exist and a black hole falls into one, it could be detected through gravitational waves.
- Gravitational waves are ripples in spacetime that were predicted by Einstein in 1916 and detected for the first time in 2016.
- Wormholes are theoretical tunnels in spacetime that could allow for travel across space and time.
- The study used computer models to analyze the interactions between a black hole and a stable traversable wormhole.
- Detecting unique gravitational signals when a black hole enters and exits a wormhole could provide evidence for the existence of wormholes.
A new study explores the intriguing possibility of detecting black holes falling into wormholes by observing gravitational waves. Gravitational waves, predicted by Einstein’s theory of general relativity, are disturbances in spacetime caused by the movement of massive objects. While gravitational waves were first detected in 2016, the focus has been on collisions between objects like black holes and neutron stars. However, if wormholes exist, their collisions with black holes should also produce gravitational signals.

Wormholes are hypothetical tunnels in spacetime that could potentially enable travel across space, time, or even into other universes. Although unstable in theory, wormholes could be kept open and traversable with exotic matter possessing “negative mass.” The study’s computer models simulated the interaction between a black hole and a stable traversable wormhole, revealing distinct gravitational signals unlike any observed before.
As a black hole approaches a wormhole, its orbital speed increases, causing the frequency of gravitational waves to rise. This increase in frequency is akin to a chirp, similar to the sound produced when one raises the pitch rapidly on a slide whistle. If a black hole were to enter a wormhole, the gravitational signal would diminish as most of its waves radiate on the other side. Conversely, when a black hole emerges from a wormhole, the frequency of gravitational waves decreases, creating an “anti-chirp.”
By observing these cycles of chirps and anti-chirps, scientists may gather evidence supporting the existence of wormholes. However, the final outcome depends on the speculative properties of exotic matter found in the wormhole’s throat. If the black hole settles near the throat, it could disrupt the wormhole and convert its mass into an extraordinary amount of gravitational waves. Alternatively, if the wormhole encounters a larger black hole, it may collapse and form a new black hole.
Further research could explore the interactions between wormhole matter and normal matter, as well as complex scenarios involving spinning wormholes. Understanding the behavior of gravitational waves and the variety of orbits in these situations would deepen our understanding of these theoretical phenomena. While wormholes remain highly speculative, the possibility of providing credibility to their existence through the detection of gravitational waves is undeniably fascinating.
