Black holes and wormholes share striking similarities as solutions to Einstein's general relativity equations, both wielding immense gravitational pull. The crucial difference: nothing escapes a black hole's event horizon, while a wormhole could theoretically permit two-way travel. Though wormholes remain hypothetical, physicists suggest some supermassive black holes might be wormholes in disguise—revealed by their unique emissions.
Unusual gamma-ray signals could unmask supermassive wormholes masquerading as black holes. These spacetime tunnels, predicted by general relativity, might connect distant points, though their formation remains a puzzle.
To differentiate them, researchers focus on supermassive objects—millions to billions of solar masses—at galaxy centers, like Sagittarius A* in the Milky Way, weighing about 4.5 million solar masses.
Matter plunging into a wormhole's mouth would accelerate to extreme speeds under its gravity.
Modeling matter flows through a wormhole's dual mouths to its throat, physicists predict colliding plasma spheres erupting from both ends at near-light speeds.
These models contrast wormhole emissions with those from active galactic nuclei (AGNs), which outshine entire galaxies via surrounding accretion disks and polar jets.

Wormhole plasma spheres could hit 18 billion °C, generating gamma rays at 68 million electron volts. AGN accretion disks stay too cool for gamma rays, and their jets beam emissions directionally—spherical motion hints at wormholes.
In Seyfert type I galaxies, where hot gas accretes rapidly, AGNs rarely spike at 68 MeV gamma rays. A strong signal there? It could signal a wormhole, per the study.
