Simulation and Clues: Cosmic Rendering

Some of us love to travel and most of us are the photographers. We always seek to see as far and clear as we can, but no matter how good our lenses are, there is always a horizon beyond which we can’t see and things beyond are mysterious. That horizon is something beyond which everything is blurred or even invisible. No matter how fine and precise our lenses are, we have a limit. This is very much in analogy with simulations that we perform in our current day computers. We make rules to make sure to render and simulate only the part that’s necessary and relevant, and when we shift our focus from one point to another we mostly compromise with some other aspects of simulation, all this to maximize the resources and optimally use the computing capabilities of computers. The best possible example of such simulation is the Video Games of this generation. The very logic behind such games is to render a world for you where you can interact, explore and go on an epic adventure. But these games don’t render the whole world (or the Universe) at once, what they do is to create a view range beyond you see nothing but emptiness. No matter how far out you reach the simulation will still create something beyond and will remove something that’s far behind you. In reality, there is a Sphere of Horizon that moves along with you, and you are always at the center and in a way you can never see what’s behind that sphere and thus keeping the simulation in such games in a balanced state.

Earth’s location in space might seem to put mankind in the center of the Universe. However, like that same ship in the ocean, we cannot tell where we lie in the enormous span of the universe. Just because we cannot see land does not mean we are in the center of the ocean; just because we cannot see the edge of the universe does not mean we lie in the center of the universe.

Simulation Universe

Our own universe is very much like this. Physics finds Universe to be somewhere around 13.8 Billion years old and thus our visible Sphere is 13.8 Billion light years in radius (considering the speed limit of light) but considering the expanding space makes the observable universe somewhere 46 Billion Light years in radius. Thus we can see things that are 13.8 billion Light Years away and simultaneously observe things that are currently 46 Billion light years from us (both are the same things, one is the ghost of the past and one is the  present). Let’s assume for a moment that the Universe is infinite, but no matter where we are in this universe our sphere of horizon will be 13.8 billion light years in radius and our view range will be 42 billion light years, as if the cosmic computer is trying to optimize its resources by applying a visual barrier, and that’s not only applicable to cosmic entities but the same resource optimization occurs when we dive deeper into quantum realms. We will discuss about the quantum realm in the next post, the purpose of this post is not to conclude but to open new doors of imagination and to change the way we look at this world.

Simulation and Clues : Frozen Time

Look around, and you will see how time governs everything around us. On a cosmic timeline we mark events, when we have to wake up, eat, sleep, a day is over, monsoon arrives, a new year begins and a millennia ends. For long, we have considered time in three distinguishable phases i.e. past, present and the future with 2 simple rules that we can’t change the past and can’t predict the exact future. We experience time as a river; always flowing in one direction. But what if we are wrong? What if Time is like a frozen sea where past, present and future exist all together? Well, let’s try to figure it out.

Human civilization has always looked for ways to accurately measure time. The standard way to measure time is by looking at the naturally occurring repetitions and cyclic events like sunrise and sunset, full moons, constellation and movements. But in the last one century, we have achieved a precision of almost a billionth of a second by observing atoms. Yeah, we can measure time almost up to a billionth of a second. But no matter how accurate clocks are, they are unable to tell what time itself is. What is it that we actually measure? And yet if we remove the concept of time and its measurement, the world will collapse.

Now let’s see what modern physics has to say about time. During the early 2oth century, Albert Einstein proposed Time as one of the dimensions of a 4-Dimensional framework of the Universe called Space-Time. We used to believe that time is the same for everyone, everywhere at the same rate, but Einstein’s groundbreaking idea changed everything. He realized that time can run at different rates for different individuals depending on the speed they are moving and the surrounding mass. He believed that more you have of one (time-speed) less you have of other. Even if you don’t move in 3-Dimension, you always move through time. But when you move through space it affects the passage of time for you, and once you reach the speed of light, time stops. With this concept in mind and without going deep into underlying mathematics we can say what whatever we observe as time is in reality just a slice from cosmic timeline where everything that ever happened or will happen is already out there. We still see stars as they were 14 billion years ago, and they are probably already dead. We still see supernovae which exploded almost millions of years in past. So you see the concept of time mainly depends on where we are in space-time and how fast we are moving.

In simpler words, the difference between past, present and future is mere an illusion. Time itself is like a video made up of infinite frames. And it’s only when you move forward frame by frame, the concept of past, present and future comes into existence. NOW, here comes the similarity between our Universe and a simulation. You can easily compare this model of time with any form of computer simulation, video or video games and the likes. The characters or elements of these simulations will always experience time as if it’s flowing in one direction. Their perception of time will be exactly the way we perceive time, but we know their perception is WRONG. We, those who are outside these simulations, can always forward, backward, pause or stop it any moment and the people inside it may never realize. For those who are inside, time is as much of a mystery as it is for us. Even they will try to define their short existence as Past, Present and Future. Maybe if within those simulations, there is someone like Einstein who leads them to see time as a fourth dimension, would that make them wrong?

Probably we will never know for sure. Probably time is really like a frozen ocean where all our existence exist together.
