The existence of wormholes, which are pipelines that connect two distinct places in space-time, has been theoretically established by physicists at the University of Cambridge. If a piece of data or a physical item can flow through the wormhole, time travel and immediate communication across huge distances may become conceivable.
“But there’s a problem: Einstein’s wormholes are extremely unsteady, and they don’t stay open long enough for something to pass over.”
In 1988, scientists deduced that a sort of negative energy known as Casimir energy may keep wormholes open.
The Cambridge hypothetical answer is based on the principles of quantum energy, which implies that even vacuums are seething with energy waves.
“Does this mean we have the technology for building a wormhole?” asks Matt Visser at the Victoria University of Wellington in New Zealand. “The answer is still no.” Still, he is intrigued by Butcher’s work. “From a physics perspective, it may revitalise interest in wormholes.”
If you imagine two metal plates in a vacuum, certain waves of energy will be too large to fit between the plates, implying that the space-time between the plates will have negative energy.
“Under the right circumstances, could the tube-like shape of the wormhole itself generate Casimir energy? Calculations show that if the wormhole’s throat is orders of magnitude longer then the width of its mouth, it does indeed create Casimir energy at its center.”
