Consider answering following questions about time (Do not just read these questions, but think about them for a little bit). I call them mind-benders.
- Can every moment in time of the past exists somewhere?
- Does past actually exists somewhere? If it does, Is it than stored somewhere?
- How about the future or present? Can future and present exist somewhere?
- Can you define present? How long does the present lasts?
- If you think that present exists, then where is it? If you think that past exists, then where is it?
When you really think about it answer is so simple that even child could understand it, so we conclude following: no past, present and future can exists without violating at least dozens of physics and logical laws; which in turn would imply that time does not exists.
Passage of time is just an illusion we made up to cope and measure the change. No more and no less; Everything else in between is work of our imagination, science-fiction writers and physicist with too much time on their hands. That is essentially what this article will be about. Just a thought exercise to see if we can have a logical world with no time existing.
Let’s first start with the quote:
” A famous philosophical argument says that, if the future were real, then it would be fixed now, and we would not have the freedom to affect that future. Since we do have that freedom, the future can’t be real”
What this quote is essentially saying is that predetermined future cannot exists because we’re the ones that are making it as we go along. If that kind of future did exist somewhere, than we would not be able to affect it with our own actions. So no matter what I did, my future would always remain the same.
We all know stories and science fiction novels about traveling back in time or further into the future. We also know about time travel paradoxes. Most famous being grandfather paradox. It goes like this:
If you went back in time and killed your grandfather, you would not exists since he would not be able to have children of his own. He would be dead and you would’ve never been born. But, if you weren’t born you would not be able to go back in time to kill your grandfather in the first place since you didn’t exist, but obviously you do exist and you did go back in time and you did kill your grandfather. This creates a logical paradox and big inconsistency in logical thinking. But we’ll come back to this later in the article.
There’s another paradox which physicist don’t talk about, but to me it seams like even stranger paradox than the grandfather one. I’m sure someone else though of this but I’ll just state it. It goes like this:
Today is 2008, and let’s suppose you went back to 2006 to meet yourself. Now there’s two of you. How would that be possible without violating Conservation of Energy Law, which states that matter cannot be created nor destroyed. It can only change forms. Obviously since there’s two of you occupying same space and time, one of you was created. Either that or you are leaving copies of yourself on every instance (frame) in time which would violate the law even further.
Another example: Imagine taking the whole earth back with you to only yesterday. You would now have two earths in the same orbit! You would have increase in mass and God knows how would that affect the space in our Solar System. You might try to counter this argument by saying that it would not be possible to take anything with you back in time; But with that logic you wouldn’t be able to take yourself back in time either, so time travel would still not be possible.
Let’s take that little further and say that from 2006 you wanted to jump to 2000 and look up yourself there too. Now there’s three copies of you. Two copies of you exist in the year 2000 and one that you left in 2006. Or would that 2006 copy of you just disappear? How would that actually work?
It gets even more complex and illogical if one wants to define instance. What’s one instance? What is NOW? Is it one second? One microsecond? Nanosecond? How about picosecond? You can pretty much go to infinite regression and make no progress of defining NOW.
It seems that we’re creating problems that don’t really exists, and and then trying to find a solution for it.
Einstein wrote extensively in his papers about time. The whole premise of General Theory Of Relativity revolves around time. However, Einstein did claim that traveling to past is not going to be possible. I happen to agree with that, but for different reasons. Einstein’s relativity claims time is directly correlated to mass, speed of light and energy (E=MC2) and that nothing could travel faster than light. Faster you go (higher your velocity), slower the time passes for you.
If you were to ever reach speed of light you would have to become one dimensional and would have no mass. Like photon particles. Time would then stop for you. You would not be affected by time. Just like light is not affected by time. It is one of the constants in universe. But you would never be able to catch up with the light anyway.
If you would to travel along side of light; It would not matter how fast you were going; from your perspective, light would still be going 186,000 miles per second. For example: If you were to travel close to the speed of light (185,000 miles per second lets say), light would still be going 186,000 miles per second respective to you. Not only you would never be able to catch up with it, but it would look as if you were just standing still and light is just zipping by you regardless of your speed.
Now, in order to go back in time you would have to travel faster than the speed of light and have negative mass. Einstein believed that is not possible.
Lets now see solution for all these inconsistencies and paradoxes. New speculative-theory which states that time does not exists solves this and many other problems. It states that time is just an arbitrary concept we made up and it’s only a measurement of change. Nothing more. Every kind of change for that matter. Just like a mile is measurement of distance. Mile doesn’t really physically exists. Same thing with time. Time as a physical or multidimensional entity doesn’t really exists. We use concept of time to measures changes in our body, motion, aging etc. Nothing more.
Without time there’s no grandfather paradox. Here’s how:
You would not be able to go back in time to kill your grandfather because your grandfather is here! There is no such a thing as “before”. Maybe your grandfather is not alive right now, but in whichever form, he is definitely here. Yes he was alive 20 years ago, but right now he is physically HERE, in a different form, made of different particles, but that doesn’t mean that there’s another copy of your grandfather existing back in 1950′s or 1968 or any year you happen to pick. What we are witnessing is the changes in your grandfather, from the fetus do the worm food.
The only proof of your grandfather existing in the past you have is memories of him. Having memories of your grandfather don’t mean he still exists in the past. If you for example look at a photograph of your grandfather to remind you of him; would that mean that your grandpa from the photograph still exists somewhere? And if he does exists somewhere in time; that would mean that every other instance of your life also exists somewhere in time. And we just showed that you really cannot define the instance.
Here’s another example with photograph: Lets say you pick up the photograph of yourself, and in that photograph you have a black eye. That black eye has healed so far. But does it mean that your black eye from the photograph still exists somewhere? I think we can see false logic here. Your black eye cannot exists because the eye you’re reading this text with now, and the black eye from the past are actually the same eye. The only difference is in change. Black eye has healed (dead cells got replaced by healthy ones etc…) and turned into normal healthy eye, but it’s the same eye that always occupied the same space, your head.
We’ve created paradoxes like “grandfather’s paradox” only because we assume that there are multiple copies of your grandfather you can go back to. I think it is more natural to assume that time as a physical entity does not really exists, and that the only way to go back in time is to UNDO the changes that affect you and your surroundings. That would mean to put everything (and I mean everything) back the way it was let’s say 20 minutes ago. You might as well say “going back in change” instead of “going back in time”.
I will give you analogy for this example but before I do that let’s define what it means “to age”. To age simply means cell death. Your cells are dying and getting weaker and weaker so you have sense of aging. That’s it. Time has nothing to do with it. Time as a physically (or logical) entity cannot make you age. Death of cells is the only thing that takes place. The only reason you feel weaker as you age is because of billions and billions of your cells are dying ever day but they don’t get replaced by the same amount. Remember this since you will need it for the next experiment.
Going 20 minutes back in “time” in a world with no “time” experiment
I have been thinking of an analogy to use here to accurately describe what happens in a world with no time so hopefully following analogy will explain it well. As you read following scenario please try to visualize events happening.
Imagine yourself siting in the middle of a small room on a wooden chair.
There’s nothing in the room but you, four walls, ceiling, floor and that wooden chair.
You absolutely are not doing anything but motionlessly stare at the wall.
It seems that nothing is happening and that time is standing still. But that is not true. Atoms in your body as well as atoms and molecules in walls around you and chair underneath you, are in constant motion and are changing constantly. Even the air around you is in constant motion.
After 20 minutes, wooden chair breaks and you fall and bruise your butt. The act of chair breaking is the only thing you’ve been aware of in those 20 minutes. If chair did not break you would not be able to tell the difference between minute 2 from minute 5 lets say, but since now you have a reference point (chair breaking), it seems like some time did pass and you would be able to pin point differences between minute 2 and 5. It would be easy because you would use breaking of a chair as a reference point. Keep with me here, we’re almost done.
Now ask yourself: What would it take for you to go back in time when chair was whole and your butt was bruisless? Can you guess by now? No, not a time machine or a worm hole.
To truly go back in time, all you would have to do is to revert changes back to way they were 20 minutes ago. And that includes everything: the chair, your body, floor, ceiling, air molecules and four walls around you.
- That would mean putting back and re-arranging every molecule back where it was.
- Every atom in that broken chair would have to be repaired and reassembled the way it was 20 minutes ago.
- That would also mean you would have to cure your cells from aging and revert them to state they were in 20 minutes ago. Cells don’t just disappear after they die. They turn into energy, so you would also need to convert some of the lost energy back into cells. That would also cure your bruise.
- You would have to rearrange your neurons in your brain to reflect original state which was 20 minutes ago, which would in turn erase your current memories.
- Every molecule and atom in the walls, ceiling, floor and air around you would have to be rearranged, converted and reverted back to the 20 minutes ago.
Once everything is done, you could say that you truly went back in time without time. Then there would be no difference between you (and the room) right now and you 20 minutes ago. None whatsoever. You went beck in time without time really existing. But that would only apply to you. Outside world would still be unaffected by your molecule rearrangements and would continue aging and changing, but you would be 20 minutes younger.
Of course in current practice all this is impossible and irreversible without using up godly amount of energy. Just imagine the feat of trying to revert changes just for the room example!
That is exactly why we have grandfather’s paradox. If your grandfather is dead right now, the only way to see him alive is not go back in 1950′s, but to revert changes that lead to his death. And that includes everything. Going back in time with a time machine would created logical paradox which doesn’t make any sense since it would require multiple copies of grandfathers to exists which violates not just logic but our fundamental laws of physics. We only have illusion that time exists because we use it to measure the actual change. It’s simple as that.
I realize that some of these examples are really simple and maybe point of view a true realist would have, but sometimes in order to see the truth, we need to oversimplify things to get past the clutter and fog.
This is the point where you ask: “What about relativity? If there’s no time, how come that we’ve observed that time does slows down for a person in motion?” Good question, but that’s illusion too. Person’s perception of time slows down because everything in his/hers body slows down as they go faster and faster. That includes: heart rate, brain neurons, cell division, cell death, protein forming and the whole enchilada. At this stage person’s perception of everything slows down. Relativity also treats time as one and the same entity as space. If there’s no space there would be no time; so “no time” theory would not affect relativity at all. Think about it. If there’s no space than it would be impossible for matter to exists. If there’s no matter and space, there would no occurrence of any changes taking place and time would still not exists.
The fact is that time still remains more of philosophical question than anything else.
