I know I just wrote an update post last night, but I was reading this article in new scientist (well I’m still currently reading it.. I haven’t finished it) and it sparked my brain to probe a little deeper into this. When you think of time, what do you think of? You think of a set of numbers, according to what time zone you are in, that ticks on and on while you live your life. We base everything off of time; sleep, work, activities. What are we really basing our life off of? This is such a mystery even at present day, that the top scientists, physicists, theorists and philosophers had a recent meeting about what time really means. We have a set of laws for physics that have been deemed eternally true. The universe has only been around 14 billion years; how do we know that these laws can’t change and evolve if we haven’t had them long enough to study any kind of change or pattern? The universe evolves.. and so will time, matter and space.
When you have a clock swinging its pendulum, and the minute hand moving, what is your first conceived though? Naturally your brain links the movement of both to TIME. But what physicists are saying is that there may very well be no time. Or at least no time that depends on matter. What if the minute hand moves in relation to the number of swings of the pendulum, and simply not because time is ticking away? If you wrap your head around it you’ll start to see why time is such a big case to handle. We all know that I looooove quantum physics and mechanics (Which does not mean I understand it all, but I do have an immense interest in it). In quantum theory, time doesn’t play the role of an observable. When we have a molecule, we might observe it doing only one thing, or only being in on state, but in quantum theory there’s an endless amount of directions it could be going. Just because we didn’t directly observe it does not mean that it’s not occurring. In a quantum state, particles move both backwards AND forwards in time. In order to make a correct assumption about the present, we need both the past and future to play a role. While something is happening now, there is something happening in the future that is moving backwards towards the present.
Really, I might sound like I’m babbling, but quantum laws are the weirdest and most confusing things ever. It’s seriously stuff out of a movie, except it’s starting to have evidence to back it up as true. Quantum researchers are beginning to do some experiments and research with electrons and photons where the observations that they were making might be affecting their past. So with THAT being said, if particles can move both backwards and forwards, why do we perceive time as only moving in a forward direction?
The sunrise and sunsets change throughout the course of the year. They do not change because they are bound to time, they change due to the earths rotation and everything like that. If time WAS tied to the sunrise and sunset, then the time would follow when the event occurred. It does not. Therefore the physical events ARE independent of time. So to say that particular events occur relative to time is completely irrelevant. This goes back to the pendulum theory… is a physical object linked to time? Or are they independent of eachother? Does time exist only because we assigned a value to it?
Time is merely constructed in accordance to events or physical things around us. Newton claimed space and time existed independently of one another, and leibniz claimed that time and space only exist as properties of objects and things, and the relationships between them. We all know that astronauts traveling fast enough are actually moving into the earth’s future… so why is a time machine so far out of the question? By all means, ridicule me but I’m just being honest. I think people are so afraid of science because of what it implies. We don’t know barely anything, we haven’t even touched upon the surface of what makes this universe tick. I think we should all start thinking a little harder about it…
