A research paper by British Lancaster University, published on the pre-print database arXiv, theorizes in a publication that wormholes — hypothetical space portals linking two very distant points of space-time — could arise from so-called axions.

Axions are hypothetical particles that, according to some theories, make up large part of the universe's dark matter — the undetectable stuff that constitutes the scaffolding of galaxies.

Axions are scattered around the universe and interact among themselves through electromagnetic relations, the paper explains.

They also have a very peculiar property: when they are close enough to strong magnetic fields, they can be transformed into "negative energy" or "exotic matter."

Exotic matter is exactly what, according to current astronomical theories, is necessary for wormholes to appear.
