What Is A Wormhole?

A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe. Wormholes are predicted by a theory of general relativity. Be aware that wormholes do cause dangers of sudden collapse, high radiation, and dangerous contact with exotic matter.

The Theory Of Wormholes- Wormholes were first hypothesized in 1916, though that wasn't what they were called at the time. While reviewing another physicist's solution to the equations in Albert Einstein's theory of general relativity. Austrian physicist, Ludwig Flamm realized that another solution was possible. He described a "white hole," which is a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit. In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance. The shortcuts came to be called the Einstein-Rosen bridges, or wormholes. Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

What Do Wormholes Contain? Wormholes contain two mouths, with a throat connecting the two. The mouths would most likely be spheroidal. The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require.

Through The Wormhole- Science fiction is filled with tales of traveling through wormholes. The reality of such travel is more complicated, and its not just because we've yet to spot one. The first problem is size. Primordial wormholes are said to exist on microscopic levels. However, as the universe expands, it is possible that some may have been stretched to larger sizes. Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly. More recent research found that a wormhole containing "exotic" matter could stay open and unchanging for longer periods of time. Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a large negative pressure. Such matter has only been seen in the behavior of certain vacuum states as part of quantum field theory. If a wormhole contained sufficient exotic matter, whether naturally occurring or artificially added, it could theoretically be used as a method of sending information or travelers through space. Unfortunately, human journeys through the space tunnels may be challenging. Wormholes may not only connect two separate regions within the universe, they could also connect two different universes. Similarly, some scientists have speculated that if one mouth of a wormhole is moved in a specific manner, it could allow for time travel. Astrophysicist Eric Davis says that "You can go into the future or into the past using traversable wormholes."

Today's technology is insufficient to enlarge or stabilize wormholes, even if they could be found. However, scientists continue to explore the concept as a method of space travel with the hope that technology will eventually be able to utilize them. You would need some of super-super advanced technology. "Humans won't be doing this any time in the near future."
