Wormholes have always been a part of science fiction, whereby they provide a way in which travelling can transpire rapidly. These types of shortcuts have always intrigued science and have always remained hypothetical. On the other hand, there is a rise in the talk of negative energy and whether or not it has a hold on wormholes actually existing.
Negative energy is a key hold and an ingredient to the existence of a wormhole. One thing though, this discovery sort of distorts the laws of physics and opens the door to the possibility of traversable wormholes. The concept of negative energy varies from person to person, but what does it mean and how is it linked to wormholes?
The strange force that could bend spacetime is negative energy
Have you ever been to a place and felt uneasy or perhaps your mood changed? Have you ever talked to someone and somehow felt uncomfortable? That is called negative energy. The energy that a place or person has does not bring light at all. However, in this context of negative energy, is it the same as one that is associated with wormholes?
Negative energy is one of the strongest and yet strangest feelings and concepts in modern physics. Negative energy is the opposite of positive energy; let us say something like the opposite of the example I gave above about a place or person. Now, when it comes to science and physics, it has an inverse effect on gravity and spacetime. It behaves in a way that defies common sense.
According to Big Think, we know from quantum mechanics that energy exists even in empty space. Therefore, having less energy than empty space is referred to as “negative energy.” The problem is that no one knows how to do this, and it might not be feasible. Having said that, researchers believe, after experiments and findings, that negative energy might exist in measurable amounts under certain conditions.
Is it possible for wormholes to allow faster-than-light travel?
While studying the behavior of particles in regions of extreme gravity in 1935, Albert Einstein and his colleague Nathan Rosen discovered that they could develop mathematical solutions that connected two black holes via a wormhole, or tunnel. Theoretically, things may travel via the wormhole in very little or no time at all. The only issue is that they need negative energy to support the wormhole’s stability, or its ability to remain intact, expressed Big Think.
Because it directly addresses one of the main obstacles to interstellar travel—the great distances between stars and galaxies—the finding of negative energy is intriguing. It would take more than 70,000 years to go to Alpha Centauri, the closest star system, even with the fastest spacecraft ever constructed. However, if negative energy could stabilise a wormhole, it might hypothetically create a shortcut that would enable humanity to travel across space in a matter of seconds.
What this signifies for physics and space travel in the future
The discovery is exciting for scientists because it has given them leverage to figure out how to make travels happen through this wormhole theory, although the laws of physics might shift a little. If scientists can master it and understand everything, it will definitely change our perspective and lead to technologies we can only imagine today.
From all of this, you can now see that negative energy is a thing; it exists, but it has so many hats and contexts. One has to know what exactly is being explained. Although it carries that same aspect in both physics and normal life, there is still a difference. For those, you have to figure out how to lower the energy of space itself below the bare minimum, and we don’t know how to accomplish that. Yes, it might be impossible, and it most likely is.
