"Introduction"
The inevitable wondering of time, how can I build a time machine? can we really achieve the speed of light let alone be faster than light itself. Time travel has long captured the human imagination, inspiring countless works of science fiction and fueling discussions about the nature of time and reality. While time travel remains a speculative and theoretical concept, it has intrigued both scientists and the general public alike. In this essay, we will delve into some of the theoretical concepts surrounding time travel, including Einstein's theory of relativity, the idea of wormholes, time dilation at high speeds, and the potential violation of causality. While no practical method for time travel exists as of my last knowledge update in September 2021, these concepts provide a glimpse into the intriguing possibilities that the future of physics might hold.
Einstein's Theory of Relativity and Time Dilation.
One of the most profound insights into the nature of time comes from Albert Einstein's theory of relativity. According to the theory, time is not an absolute entity but is intertwined with space in what is known as spacetime. The theory of special relativity, introduced in 1905, showed that time can dilate, or stretch, depending on an observer's relative velocity. As an object approaches the speed of light, time for that object slows down compared to a stationary observer. This phenomenon, known as time dilation, has been confirmed through experiments involving particle accelerators and high-speed particles. While this concept doesn't provide a means for traveling backward or forward in time, it offers insights into how the fabric of reality might behave under extreme conditions.
Wormholes: Bridges in Spacetime.
The concept of wormholes, popularized by science fiction, presents another theoretical pathway for time travel. A wormhole is a hypothetical tunnel that connects two distant points in spacetime. If these structures were to exist and remain stable, they could potentially offer shortcuts through space and time. However, the challenges associated with wormholes are formidable. To keep a wormhole open and traversable, it's theorized that exotic matter with negative energy density would be required. The existence of such matter is purely speculative and defies our current understanding of physics. Furthermore, the stability of wormholes and their potential to violate causality, or the principle that cause and effect must follow a chronological order, raise complex questions about the feasibility of time travel through these structures.
Causality Violation and Cosmic Strings.
Some theories explore the possibility of pathways that might loop back in time, challenging the principle of causality. Cosmic strings, for instance, are theoretical linear defects in spacetime that could potentially bend space around them in a way that creates closed timelike curves. These curves could allow for paths that loop back in time, raising intriguing questions about causality violations and the potential paradoxes they might entail. However, the concept of cosmic strings is highly speculative and faces significant theoretical and observational challenges. The violation of causality is a topic of great debate within the scientific community, as it challenges the fundamental principles that underlie our understanding of the universe.
"Conclusion"
While the human fascination with time travel continues to thrive, it's important to recognize that the current understanding of physics and the universe does not provide a clear pathway for practical time travel. Theoretical concepts like Einstein's theories of relativity, wormholes, and causality violations offer tantalizing glimpses into what might be possible under extreme conditions. However, these concepts remain largely speculative, and face significant challenges related to stability, energy requirements, and the potential violation of known physical laws.
As science advances, our understanding of time, space, and the fabric of reality may evolve. The search for a deeper understanding of the universe is a continuous journey, and it's possible that new discoveries could shed light on the mysteries of time travel. Until then, time travel remains a captivating topic that inspires our imagination and prompts us to explore the boundaries of our current knowledge.

Six Feet Under
Buried alive. What a horrible way to go. Yazz lay there, in her own thoughts. What else could she do? She was hungry, thirsty, tired, mentally, and physically exhausted, and more than anything, she was bored. She hoped she would die of boredom before anything else, anything else would've been more painful. Like many people had, she and her friends had talked about what they reckon the worst ways to die were, it was a morbid subject, but it came up every now and again. Yazz had always been one to argue her point on drowning, others had mentioned burning alive, slowly and painfully bleeding to death, hung drawn and quartered, and being starved to death. It was strange that none of them had considered being buried alive, it had never come up. But now, she was thinking back to those conversations her and her friends had had, how could they have not thought about it? It took a lot longer than the others, you were completely confined, you couldn't move or do anything, you just had to wait, until your body was physically unable to support a life system anymore, which could take up to four days. Four! By far the longest out of all of them. She recounted some of these conversations just to try and pass the time, anything to pass the time. It was difficult to know how much time had passed since she had been underground, it was difficult to know anything. There were many things that Yazz didn't know, she didn't know where she was, she didn't know how she'd got into the coffin, she'd just woken up there. Yazz also didn't know what time it was, or even what day it was, she guessed at Tuesday, it was Sunday evening when she'd been buried alive, intentionally, and although it had felt like weeks had passed, she was still alive, which means she hadn't died from dehydration, and therefore it couldn't have been more than four days.

Some say I've got a God complex. That I'm narcissistic. I am better than a lot of other people. Egotistical, maybe, but true. I'm the best in my field. Things that bother other people don't bother me. Blood for instance. OK, not many surgeons mind that, so not the best example.
