Recently QE was found to be possible on macroscopic matter, so that may be a possibility for a usable wormhole. They figured out quantum entanglement could be used to do the same thing, but QE only works on a microscopic scale. In particular, one of the motivations of Morris and Thorne was to find wormholes solutions that do not have any event horizons. "That was something of a surprise: Given that … Today's technology is insufficient to enlarge or stabilize wormholes, even if they could be found. … The idea of using wormholes to … They were "successful". However, as the universe expands, it is possible that … “Better wormholes are possible by using a Randall Sundrum II model with a U(1) gauge field,” the researchers explain. That research concerned one of the most popular conceptions of wormholes, with black holes serving as one of the openings. Wormhole Tunnels in Spacetime May Be Possible, New Research Suggests. Fomulating a precise definition of "wormhole" is not easy. "Larger wormholes are possible with a special type of ”dark sector”, a type of matter that interacts only gravitationally with our own matter. NASA’s conducted legitimate wormhole research for decades, and a team described just this year how wormhole-based travel might be more feasible than previously thought. A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. “The spheres of plasma from wormholes can reach temperatures of about 18 trillion degrees Fahrenheit (10 trillion degrees Celsius),” Choi writes. "Traversable wormholes are possible, consistent with the known laws of physics," Jafferis told Newsweek. The usual dark matter is an example. A physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible. In that case, the black hole would create the entanglement and superposition of itself or it can make other lower energetic black holes oscillate with the same frequency. Wormhole tunnels are possible, but traveling through them may not be, according to scientists researching the spacetime theory. ... making it possible … These gateways link the magnetic field of our planet to that of the sun, setting the stage for stormy space weather. So the wormhole would be an extremely large version of the quantum superposition. Previously negative mass matter was needed to prop a wormhole open. Although some wormholes do involve black holes and white holes, this not a standard definition of the term "worm hole". There may be realistic ways to create cosmic bridges predicted by general relativity Is the solution for the question of the forming of the wormhole in the quantum entanglement? Primordial wormholes are predicted to exist on microscopic levels, about 10 –33 centimeters.
