Black holes/worm holes

When matter is sucked into a black hole, it vanishes, leaving only its gravity behind. It is a situation difficult to comprehend. What makes it even more mysterious is the fact that nothing can be learned of what goes on inside a black hole since nothing can leave it! This mystery sparks the imagination of scientists and writers alike. Some say that, upon entering a black hole, things simply cease to exist as matter, turning into some form of energy. Others say that whatever enters gets into a different reality, a parallel universe, or a different dimension. What do you think happens inside a black hole? Use your imagination, powered by what you have been learning in astronomy these past weeks.

A black hole is a disruption is space where when an object (like light) passes the Schwarzschild radius, it can't escape massive gravitational pull and eventually collapse in on itself. Although we can't see black holes, objects have this X-ray when heated to multi-million Kelvin before passing through the point-of-no-return. The object is crushed, because of no second black hole connecting it. The event horizon is the opening of the black hole. Light can't escape the event horizon, because it's collapses into atomic smithereens inside.

To answer the second question, there must be a worm hole involved! A worm hole is supposed to be two black holes on either end which create a tunnel between them. The tunnel is called a 'bridge'. I am guessing most wormholes are "Morris-Thorne" type over "Einstein-Rosen bridges", because I'm not into time travel that much. The Einstein-Rosen theory says once you pass through an "event horizon"; the spaceship will end up in a parallel universe or a different timeline when it comes out the other worm hole. Star Trek does this a lot. Due to Groom Lake, I suggest most theoretical worm holes are of the Morris-Thorne type. The Morris-Thorne type wormholes use the exotic matter and negative dark energy to stabilize it though a vacuum fluctuation. This has been proven by the "Casimir effect". The Casimir effect says that objects move to other objects, because energy fluctuations (or vacuum fluctuations),vacuum energy, and a electromagnetic field make it so. The "Morris-Thorne-Kuhfittig" wormhole is a more detailed description of the Morris-Thorne type which allows human hibernation at 10 G-forces acceleration to achieve 32 days to travel a full light year! Peter Kuhfittig wants a wormhole to be lower mass, because the less resources used to travel the bridge. His suggestion is a 1.36×1017 kilograms mass wormhole for traveling. The spaceship would need a functioning version of the alcubierre drive where the spaceship rides a wave through space through the Morris-Thorne-Kuhfittig wormhole tunnel. A second way of spaceship propulsion used through a "Morris-Thorne-Kuhfittig wormhole" I suggest should be the inferior electromagnetic catapult (coilgun engine) design on-board. This will slingshot the spacecraft across the bridge tunnel in 32 days per light year. The spaceship would need a nuclear reactor for electrical power to accelerate matter to create boost power in the opposite direction.
