Wormholes are hypothetical shortcuts between two distant points in space-time. They would allow us to travel faster than light, and according to Einstein’s general theory of relativity, they might exist.
Theoretically, wormholes could be created using exotic matter, such as dark energy, or even ordinary matter.
Wormhole shortcuts are called tunnels and they are theorized to be possible because of Einstein’s theory of relativity. In general relativity, gravity bends the fabric of space and time, allowing for shortcuts between two places.
This is similar to how a highway can link two cities together without having to go through each city individually.
Wormhole physics is an area of research that explores whether it is possible to create these tunnels. If wormholes do exist, then would we be able to travel through a black hole into another Galaxy? This article takes a closer look.
What Is A Wormhole?
A wormhole is a tunnel that connects two different parts of our universe. It’s also known as a “bridge” or “tunnel.”
In science fiction, wormholes have been used to transport people from one place to another. But in real life, scientists think that wormholes may not be so easy to use.
To understand what a wormhole is and why it has never been found, you need to know about space-time. Space-time is the four-dimensional continuum that describes everything around us.
Think of it like a sheet of paper with three dimensions (length, width, height) and time on top.
A wormhole would essentially be like folding the piece of paper, so two points that are actually incredibly far away from each other, are then connected, allowing for a swift journey from one to the other.
When you enter a wormhole, you cross over the boundary between two universes. This is called crossing the event horizon. Once you cross the event horizon, you cannot return to your original universe.
Instead, you end up somewhere else entirely. Scientists believe that wormholes are formed during the Big Bang. As the Universe expanded, it began to cool off. Eventually, the temperature became too low for atoms to form. This meant that the Universe was filled with space.
Then, at some point, the Universe exploded. This explosion caused the Universe to expand faster than its normal rate. Because of this expansion, the Universe started to contract again. The contraction created a huge amount of pressure.
This pressure squeezed the Universe until it finally collapsed back onto itself. At this point, the Universe was extremely hot. The matter could no longer stay in its atomic state.
Instead, it turned into plasma. Plasma is a gas that consists of charged particles. These particles can move very quickly. They can even travel faster than light. This means that they can travel through space-time.
When this happened, the matter was compressed together into a tiny area. This process resulted in an intense gravitational field.
If you were to stand near the center of the collapsing Universe, you would feel a strong pull towards the middle. This pull is called gravity.
Gravity is always pulling objects toward each other. It works just as well whether or not those objects are touching. When the Universe collapsed, it also contracted space-time. This contraction created a hole in space-time.
The hole was so small that it was invisible. However, because of the extreme density of the plasma, the hole was extremely powerful. It was able to create a tunnel through which anything could pass. Wormholes are therefore tunnels through space-time.
Can You Travel Through A Black Hole Into Another Galaxy?
The findings of traversable wormholes come after a recent finding of a way of maintaining the bridge based on a connection between wormholes and quantum theory.
It came across after attempts to solve a problem obsessed over by some of the greatest theorists on our planet such as Stephen Hawking, and they ask what happens to objects that fall into a black hole?
Most people know there is no getting out of a black hole as the pull of gravity is so strong. However, Hawking proved that a black hole will not last, and instead explodes in radiation. But this contradicts one of the principles of quantum theory, which states information cannot be destroyed.
Black holes seem to be able to destroy information about what they’ve consumed. This is known as the ‘black hole information paradox’ and Hawking has failed to resolve this.
However, the answer to this might lie in the ability of wormholes to be a key to getting out of black holes. Theorists think the event horizon has many tiny wormholes that allow information and radiation to get out. This means wormholes might be traversed.
Interaction between black holes at the two ends of a non-traversable wormhole has been thought to lead to negative energy, meaning the antigravitational effect stops the Einstein-Rosen bridge from breaking down and making wormholes traversable.
This suggests you could technically travel to another Galaxy via a wormhole, yet complications could occur. Black holes need to be maximally entangled.
This means a strange quantum connection exists between objects; anything done to one will also affect the other.
Is It Science or Sci-Fi?
This idea is still theoretical but if proven true, it could revolutionize science. It’s like saying we have found a way to travel through time. Some scientists say this is impossible, but others disagree.
If these theories prove correct, then we can see how we can use wormholes for interstellar travel. They may even become a new form of propulsion.
Scientists believe that wormholes must be created using exotic matter, such as dark energy or antimatter. However, even if we do know how to create them, scientists are not sure whether they exist.
There are several theories about what kind of object might form a wormhole, but none of these theories have been proven.
Some physicists think that wormholes could be used to travel across time and space. Others say that wormholes could be useful for interstellar communication. Still, others suggest that wormholes could be an alternative explanation for the existence of parallel universes.
As yet, there is no evidence that wormholes really exist but the possibility of seeing a real-life wormhole is now the focus of research by theorists using a lot of complicated mathematics and computer models.
The challenge for these theorists is the difference between black holes and what appears to be the entrance of wormholes.
Astronomers have the technology to find out the effects predicted to exist around wormholes. This technology is known as the Event Horizon Telescope and is a global network of radio antennas that can make studies on black holes and wormholes.
After making its debut on movie screens, it could just be that the space-time wormhole is about to be more than just science fiction with this technology and the research scientists are continuing to carry out.
We hope this article has told you everything you need to know about wormholes and their potential uses. Research has shown that there could indeed be traversable wormholes, and these could transport us to another Galaxy.
However, they remain hypothetical, and it is still such a huge area of research, that nothing can be certain about these hypothetical shortcuts between two distant points in space-time.
