Is time travel possible? No one should ever say “never” because eventually someone smart will come along and tell you how to break the rules.
Time travel may seem like fantasy to some, but many physicists think it’s actually possible. Ron Mallett also dreams of traveling through time. What is being talked about here is not a fantastic dream. Ron Mallett is a respected physics professor. Mallett explains his passion: I think of myself as an ordinary person with a passion. My passion is also time travel.
Ron Mallett has longed to build a time machine for most of his life. As he stated, behind this passion lies a tragic event he experienced. When Ron was only 10 years old, his father died of a heart attack at the age of 33 because he was a heavy smoker. Ron Mallett, a physicist at the University of Connecticut, explains:
“When I was 11 years old, I came across the book that changed my life. That book was H.G. Wells’ The Time Machine. First, the cover caught my attention. Then, when I read the inside, I saw that it said: ‘Scientists know that time is a kind of void, and we can do it in that void, just as we can in space. , we can move forward and backward.’ “When I read it I remember thinking ‘this is amazing. If I could build a time machine I could see my father again, save his life and change everything.”
Maybe time travel seems like an impossible possibility, but scientists continue to research many natural mysteries to make Mallett’s dream come true. Albert Einstein said that the three dimensions of space are connected to time and this functions as the fourth dimension. Einstein called this system space time. Today we use the same model for the universe.
It is possible to curl in space time
On the other hand, Einstein also said that it is possible to bend in space-time and create a ‘shortcut’ between two distant places. This event was called a wormhole. We can visualize wormholes as a tunnel with two open entrances that appear at different points in space-time. Wormholes may also occur naturally in the universe. The Russians even use radio telescopes to find them, but using wormholes for time travel won’t be that easy. The nearest wormhole could be quite a few light-years away. Even if you manage to come across one, there’s no guarantee you’ll get anywhere.
However, some physicists think that it is possible to create wormholes in the future, although we have no idea how. In addition, they predict that wormholes may have the habit of collapsing and crushing whatever is inside. So if we’re going to put a time machine inside these wormholes, we need to find a way to avoid this annoying situation.
In this case, the mysterious phenomenon we call ‘dark energy’ may offer us a solution. In the 1990s, astronomers discovered that the expansion of the universe was accelerating when it was normally thought to be slowing down.
Tamara Davis, a cosmologist at the University of Queensland in Australia, defines ‘dark energy’ as follows:
“There’s an anti-gravity effect there. This object isn’t pulling, it’s pushing. We don’t know what it is, but that makes up most of the universe, and we call it dark energy.
For wormholes to work, their ‘mouth’ must be kept open long enough. For this, we need a tool that we can call negative energy. It’s not something that can be found everywhere every day, but the dark energy that permeates the universe fits the bill. If we can figure out what this dark energy is, we will be able to open a wormhole that we can enter from one end and exit from the other.
Tamara Davis says, “We don’t know whether we can build a wormhole or whether we have such a technical capacity, but we also don’t know what human civilization will achieve in the future. Technology is developing so fast that maybe we can reach a point where we can truly control space and time.”
Linear time can become cyclical
Wormholes, one of the approaches to time travel, are located in one of the more controversial points of physics. Ron Mallett has another idea. There are drawings Mallett made to build a real time machine. This design is also based on a book he read about Albert Einstein’s equations when he was 12 years old.
Ron Mallett has designed a desktop tool that demonstrates the fundamentals needed to build a working time machine. First, lasers are used to create circulating light beams. “The space inside this ‘laser ring’ is supposed to curve like coffee being stirred,” says Mallett.
According to Mallett’s theoretical approach, linear time can be bent into a cyclical shape because space and time are tightly interconnected. A deviation in space causes a deviation in time. According to Mallett’s study, if a sufficiently intense laser is applied in a small enough area, an alternative to the linear time we live in can be created. “If space is bent strongly enough, linear time becomes cyclical. Time that suddenly becomes cyclical can allow us to travel into the past,” says Mallett.
On the other hand, for this approach to be real, it requires a lot of power and the ability to shrink everything to a microscopic size. But once we own a time machine, we will need a detailed understanding of time itself before we can use it.
The accepted general view is that there is a fixed blocked space-time in the universe. This is the main idea from Einstein’s equations. Kristie Miller, director of the Time Center at the University of Sydney, Australia, said: “The most important thing with this model is that the ideas of past, present and future time are all real. So you can think of everything that has ever existed in space-time and will continue to exist in the past.” “The dinosaurs are doing what they were doing, and we exist now and will continue to be in future spacetime,” he says.
To help us understand the fixed model, Miller gives the following example: “We are here in Sydney right now, but there are other people in Singapore and London. These places are very real, but we are not there.” This is good news for a hopeful time traveler, as it means there is no impediment to changing the time and place we are in now.
