Is Time Travel Possible? Time Travel in the possible future. Myth or Reality?

Answering the question if Time Travel Possible or not is a debate for decades now. But today we tell you how is it possible. For understanding Time Travel and it’s future possibilities, let’s start from the basic and the beginning – ” Quantum Physics and Time Travel”.

What is Quantum Physics and How is it Related with Time Travel?

A quantum computer could travel across the universe, at least theoretically. When a distant quantum system is combined with its surroundings to perform calculations that had not been performed before, it can be said to travel through time. One of the first pieces of information to get processed by such an algorithm is how long it took for the system to reach certain states. Since each state has an associated “time” (the average amount of time between successive states), this type of information isn’t actually useful in computing anything. That same concept can also explain why some processes are accelerated (e.g., gravity) and some aren’t (e.g., sound), as well as what happens when one of these systems interacts with or collides with another. In other words, it’s possible for something to go back in time and affect events happening later.

Although quantum mechanics is fundamentally different from classical physics in many ways, both fields have similar concepts about time and space, although some may be slightly different depending on which you want to use them with. Most importantly, a fundamental element of all physical particles is a speed, which is defined as the distance of a particle from its rest frame.

Speed and Energy

The faster you move, the more energy is required to keep up. For example, if you push your finger down hard from the top of a table, a friction force occurs, creating an upward force on the material beneath and pulling you downward. If you stand very still, your hand would not exert enough pressure to create a pull against the table. Therefore, the speed of light is just about 0.1 millimeters per second, or about 7 centimeters per second per year, which is pretty fast considering our planet is around 4.5 billion years old! As an aside (or more important than an aside, since this is only theoretical), it is interesting that the theory of black holes suggests the opposite: It takes a lot of energy to collapse black holes, while photons are much less energetic. They exist in supermassive objects called blackholes, the deepest point in the observable Universe. While we cannot see them directly, they are believed to exist because of Hawking Radiation emitted in excess of mass, causing matter on either side of the event horizon to expand and vanish.

This means you will see things that are moving away from you and closer the further you get. Another reason for a lack of gravity comes from the fact that gravity only exists in the form of a weak force and can therefore only be felt on large scales like our galaxy. However, it is conceivable that gravitation has been lurking there in the background, without being noticed until recently. Because we don’t have telescopes yet that can detect gravitational waves produced in areas beyond our own solar system, we can only rely on observations made in our own galaxy.

How ‘Earth’ hinders Time Travel

As such, scientists believe that gravity doesn’t actually influence other objects in our Universe. We now know that gravity is just a minor part of everything around us that is affected by the presence of matter and energy. With regards to time, the laws of special relativity are still valid for certain phenomena. Firstly, unlike classical physics, which assumes that time continues at constant speeds, quantum mechanics says time is infinite, meaning it can jump backward or forward. Secondly, even though Einstein’s general relativity predicts there are four dimensions, not one of them is strictly spatial, but rather is affected by the relative motion of two different objects that lie parallel to each other on a flat surface. Finally, there is no absolute time or direction, according to quantum mechanics. Instead, the measurement of time is influenced by the environment around you. Due to this uncertainty, you may hear about a phenomenon where time flows differently due to the difference in the speed of light and the velocity of light.

You might notice that the past is not necessarily moving faster than the future, since it was a different location at different times! This concept is referred to as “time dilation,” even though most physicists don’t agree on whether time dilation exists or not. Regardless, it’s clear that the way we perceive time seems to have changed drastically. So far, we know that every object experiences different amounts of time, depending on its position and velocity. For example, light travels at 186,000 miles per second, but most objects under 400,000 miles per second take less than 10 microseconds to complete their journey through our Solar System. Meanwhile, if someone were to visit Earth, he would take 9 minutes to cross the equator (which is just a mathematical calculation based on the speed of light). But as soon as he got off the plane and landed, his clock moved forward.

Our sense of perception and how it affects time

According to Newton’s Second Law of Motion, any object will remain in its initial position unless it is moved by anything external to itself. At first glance, this sounds counterintuitive, since it seems like we should be able to change the time it takes for a trip to happen, since we must be slowing down! Well, maybe that’s true, but remember: Everything moves. Our perception of time is a mental illusion created to help us better understand how the world works, both in terms of space and time. To put it simply: Our brains work with images. From photographs taken all around the planet to movies playing at home, they create a visual experience of what they see, or think they see. This allows humans to effectively process and make sense of information. Unfortunately, this ability is limited to our own senses. In order for these visual representations to become truly meaningful, we need to combine a wide range of sensory input into a single, unified image, similar to how we perceive colors, shapes, textures, etc. Without the ability to do so, the human brain would be incapable of seeing what’s really out there, including things we wouldn’t know existed before.

How our brain works to perceive time?

That’s why it’s so difficult for us to determine what our eyes and ears are witnessing when we look at something outside our current reality. What we know is that these images are processed by neurons located deep inside our brain in specific parts that are responsible for processing visual data. This is known as primary vision, and is what gives us a literal picture of our immediate surroundings. Once that visual processing has occurred, we then translate those images into a series of neural patterns called secondary vision. These neural patterns are then collected and stored up inside our memories, forming associations between information. By storing up these signals, we can better determine the meaning behind what we see or feel while experiencing a particular situation. After having stored up this sort of pattern, our brain becomes capable of making connections between unrelated events that aren’t explicitly linked together. Specifically, our understanding of abstract ideas like time travel is determined not by what we currently know, but rather what we know was there in the past, and what we actually feel.

All in all, in order to describe reality, it is crucial to be aware of how our perceptions of it will shape our understanding of it. This is also known as psychological realism, and has been researched extensively over the last several decades with regard to quantum physics and mathematics. In addition, psychology plays a major role in determining how you perceive the world around you, either consciously or unconsciously. People often say certain things that only others might understand. For example, people who use slang like Geezer Butler often refer to themselves as weirdos on television, when in reality they are merely trying to make fun of outsiders. Or perhaps you might find yourself asking, “What’s going on?” after hearing somebody on the street tell you that, like a dog eating grass, you should feed it carrots instead of apples.

Time Travel through reality and possibilities.

Even though we can never fully realize the complexity of the world around us, it is easy to imagine the possibilities if we approach reality with an open mind and an open heart! That said, let’s stop here for just a minute to think about time travel. As previously mentioned, the probability of traveling back in time is extremely low. According to physicist Carlo Rovelli, an estimated 15% of the total volume in the entire universe is covered by an area larger than 1% of a quadrillion cubic kilometers. He explains that this means that there are about 200 trillion trillion square-kilometers in the whole universe, or roughly the size of Europe. Assuming an average person inhabits at most 100 cubic feet (about 23 cubic meters) of space, it would be nearly impossible to travel backward in time. Also, if you wanted to travel in reverse time, you would need more than 16 billion years. Considering that there are 8 billion seconds in a year, a year would require 56 centuries. A year is approximately 290 days, so a person would spend 292 years in exactly 11-month intervals when traveling backwards in time. There would inevitably be too much distortion caused by distortions in the fabric of time itself, and you would miss out on important details. Therefore, any attempt to travel backward in time would result in a highly improbable outcome.

Nevertheless, the problem is exacerbated by the possibility of tunneling through a wall. According to Nick Bostrom, professor of engineering at Cambridge University, this would occur if a wormhole opened up from one dimension to another. Imagine a wormhole connecting the universes in which time runs forwards and opposites in which time runs in the opposite direction, along a continuum that stretches out into infinity. Any path that goes out would end up somewhere else, so there will be no direct way to travel through time, especially in accordance with causality. Furthermore, time and space do overlap, which creates the paradox that if you travel backward through time, time itself might go back. Fortunately, these problems are solvable, but the answer is still unknown. In the meantime, for the sake of simplicity, I will assume everyone can relate, which is to say that all time travel is pointless. Luckily, technology is progressing quickly, and hopefully we would get more defined solutions to this complexity of time travel.
