Do wormholes really exist?

Have you ever wondered if there is a way to travel between vast regions of space?

This question has always intrigued scientists, and among the many concepts that researchers have developed, one has become quite popular: wormholes.

But what is a wormhole?

In theory, wormholes are connections (like tunnels) in space-time, creating a shortcut between two very distant areas of the Universe.

The idea is that space travelers can use these tunnels to quickly travel to distant regions of space that would otherwise take thousands or millions of years.

Can humans travel through a wormhole?

Science says it is highly unlikely, but not impossible. However, to create a wormhole, we need far more advanced science than we currently have.

How does a wormhole work?

According to current theories, the wormhole contains two mouths connected by a throat. The “entrance” would be a black hole and the “exit” would be a white hole.

We know that black holes are real, as they can be found at the center of many galaxies.

Although we cannot see black holes directly, we can detect their presence by the way they affect nearby matter: black holes swallow matter.

However, there is no evidence for the existence of white holes, which would be the other side of a black hole. For now, they are purely hypothetical objects.

Einstein’s general relativity mathematically predicts the existence of wormholes, but to date, none have actually been found.

Through the wormhole

Have you ever stopped to think about how big our universe is? All of our neighboring planets, stars, and galaxies are very far from us.

For example, Proxima Centauri, the closest star to the Sun, is 4.22 light-years away.

If the fastest spacecraft we currently have tried to reach Proxima Centauri, it would take more than 80,000 years to get there!

But that would change if we could travel through wormholes.

Science fiction is full of stories about wormholes, but in reality, they are much more complicated! And it’s not just because we haven’t found a wormhole in space yet.

The first problem is the size. Wormholes are expected to exist at microscopic levels, roughly 100 billion billion times smaller than the atomic nucleus. However, as the Universe expands, it is possible that some may have been stretched to larger sizes.

Do wormholes exist?

No wormholes have been found yet and perhaps it is because we simply cannot see them.

Paul Davies, a theoretical physicist and cosmologist at the University of Arizona, suggests that they can only occur on subatomic scales and last for fractions of a second.

For him, wormholes large enough for a human to travel can require a new form of physics, which has not yet been discovered.

Is it possible to artificially create a wormhole?

Researchers from Spain have actually created a tiny magnetic wormhole, and they used it to connect two regions of space so that a magnetic field could travel “invisibly” between them.

Unfortunately, they are not like those in science fiction films like Stargate, Star Trek, and Interstellar, which allow humans to travel quickly through space.

You can’t send matter through it, but physicists have managed to create a tunnel that allows a magnetic field to disappear at one point, and then reappear at another. It may not be like in the movies, but it is still extremely impressive.
