I’m not a scientist, and so I won’t even bothered to pretend to be one. I’m going to use casual terms and meanings to try to explain to everyone what I think time is. In nature, time appears to be an arrow once shoots won’t be able to go back into the quiver. Why? It appears as if time travels only in one direction. Which means, time is only moving forward. Nonetheless, this would puzzle scientists as they would ask why time could not be rewound.
If you play a CD, DVD, or any digital storage medium, you would be able to rewind and fast forward recorded time, but real time could not be streamed backward. In fact, many people who have regrets would love to wish that they could stream time in backward motion so they could jump into their past to fix their mistakes. Nonetheless, it seems time could only decay forward.
I could be wrong but in some religions, these folks would promote time is a flat dimension in which this dimension would stretch on into the infinity. They would argue that the clock is a manmade concept in which it maps relative, perceptive units of time. Since time is an infinite to these folks, they would probably argue that the relative, perceptive manmade clock is creating a fictional timeline which would help humans to be able to weave out a history of time.
Many scientists nowadays believe Einstein is correct on how time is churning, because of his special relativity theory. Basically, Einstein argues that time is relative to the observers. If you’re on a spaceship that travels near the speed of light, time would move slower, but if your friend is stationed on earth time would move faster. This means by the time you get back to him or her, this person would probably grow much older than you. This phenomenon appears to allow you to travel through time, but only in a forwarding, dimensional motion.
I have a crazy idea, and there is no proof to back it up of course. My imagination runs wild and I let it be. Basically, I argue that time is like a cup of tea. Imagine a cup of tea dips into an ocean of tea and extract out a full cup of tea, but before one drinks this cup of tea it needs some milk. I would pour in a really good type of milk to improve my cup of tea, thus this cup of tea indeed is having a great future. Nonetheless, what if I poison the cup of tea? If I drink it I would surely have a very grave future indeed.
Imagine I extract a gazillion cups of tea out of the ocean of tea, and in each cup of tea I would either enhance it or sour it. Thus each cup among the gazillion more would have a very different future according to what I would color it. Imagine the tea inside each cup is time. It’s more like captured or recorded time. Nonetheless, this recorded, captured time is weaved almost as one with the fabric of the universe itself, thus when the tea begins to cool there is no way to warm it up again.
Of course, unless you have a way to jump out of the cup of tea, pick it up, put it in a microwave and start to warm it up again with godly microwave heat. Otherwise, the tea will decay naturally and never get warm again. Nonetheless, when you jump out of the cup of tea, what space/time have you jumped into? Once you’re out of the cup of tea, you could pour it back into the ocean of tea. Does this mean you create a new time? Each new event you create with your cup of tea, it still seems to be impossible to revert time back in real time.
By that I mean when you warm up your cup of tea again, in your new space it means you’re just creating a new event with your cup of tea. It does not seem like you’re reverting time so your cup of tea would travel back in time and become the original warmed cup of tea. Nonetheless, according to Einstein, time is relative to the observers if I understand his theory correctly, this would mean the people who are inside the cup of tea would either feel like if they’re traveling back in time. Because their whole universe is warming up to how it was warmed.
Given the condition is right which gives rise to an appropriate mixing of necessary elements to create the origin time period, perhaps this is how one would experience a reverting time inside a warm cup of tea.
If my imagination is on the right track with time, then I guess you could go back in time and kill your grandfather yet you would still exist in the future. How come? Once each cup of tea got filled, it is a universe in itself. Thus what had happened in such a universe is and will always be existed in such a universe. Like a forensic expert who could walk back the crime scene even though he or she isn’t there because existing matters would allow he or she to look back in time to figure out what had happened. In the cup of tea, the universe won’t just erase its events unless you pour the tea out of the cup.
Basically, I think you could kill your grandfather in one cup of tea, and with the right conditions in another cup of tea, you would still exist. This is rather confusing, but I think it does explain why I think you could travel back in time. By this I mean you better find the right cup of tea to jump into. With the right condition, the cup of tea would allow you to travel back in time. Nonetheless, what other side effects and conditions you have created when you jump out of the cup of tea? After all, it requires you to jump out of the cup of tea’s dimension into a bigger dimension so you could find another right cup of tea to jump back into.
In addition: I forgot to mention that in our cup of tea, the tea could evaporate in time. After all in our universe (cup of tea) water does evaporate — given it enough time — even though it is not going to be boiled. So if I’m correct, can each cup of tea I’d constructed in earlier paragraphs be evaporated given it enough time? If this is true, would our very own cup of tea (i.e., our universe) be very finite? Personally, I think our cup of tea will eventually evaporate, but our species won’t be able to survive long enough to witness such an event.
