and The Reason is Here – The Universe and Connection

How we are all interconnected?This post is just a brief explanation of my last post. The post where I’ve written “The universe is full of wisdom and if you try to learn about it a little, if you try to understand about it a little then at some point it will teach you how we all are connected with each other and with all the things. In the period you try to understand about the universe, you will suddenly realize how a single perception, how a single conception plays a role in the humans life.”

There are reasons why I’ve written that and if you really want to know the reasons behind it then read the following things.
I’m just trying to explain it as briefly as I can. So, here’s it:

How can you say that we are made up of atoms? The answer to this question is not much difficult. We know that cells are made up of molecules, molecules are made up of atoms; humans and all the beings are made of cells and hence, we are made of various molecules and atoms. Now from where did these atom come from and how were they made? The answer to these questions lies in the creation of the universe. Long ago when the universe formed, at that time subatomic particles assembled into atoms and they formed hydrogen atoms. Hydrogen, the first element ever formed in the universe, the simplest type of atom. After that as the universe aged other elements were also created and that’s why it is said that every element on earth, except for the lightest was created in the some massive stars.

Now, we can say that every element in the periodic table aside from hydrogen is essentially a stardust as hydrogen is a big bang dust. So, lets see how much we are made up of stardust, and to know that we have to exclude hydrogen as it’s a big bang dust not a stardust.

Our body is composed of billions of billion atoms and in all these atoms some of them are hydrogen. Most of the hydrogen in our body floats around in the form of water and water usually makes up 55%-78%(approx.) of the human body and hydrogen only accounts for 11% of that water mass and from this, we can say that 92.5-93.7%(approx.) of the mass in our body is stardust. Hence, we are all made up of stardust and if you include hydrogen too then we are all made up of atoms, which were created in the universe long ago. Calcium in our bones, Iron in our blood, all were created in some massive stars!

However, I’m well aware of the fact that the truth can be a lot different from the theories, physics, philosophies, facts, understanding or everything and it can be a lot crazier and astonishing than we can even imagine. But so far, this is what I think about us and the universe, this is what I’ve learned and it fits into my understanding.

What Is Time?

What Is Time?

Everyone knows what time is. It is what we measure in minutes, hours, days, etc and we follow it with clocks and calendars. In simple words, it is a dimension along which events are ordered from the past through the present into the future, it is a dimension along which we measure the durations of events and the intervals between them. Don’t you think time is more than this statement? Ever you wonder, what is time? Is there something more about time?  Is it just what clock and calendar measures or something more? What is time actually?

Time is a concept, it’s a self-evident concept. We all know about it, don’t we? But there is more than that, there is a lot more about time. There are many perceptions about time, there are many theories which explains what actually time is. Early in the back days, people used sun and stars instead of clocks. Humans always felt the need of the concept of time. This post is about the time but I don’t want to go much deeper into this topic as this topic is too broader to explain with lots of theories, philosophies, physics and then of course my own perceptions about time and I don’t want to make this post too complicated to understand.

Here’s a few words on this topic, a few words to explain what I think about time in very simple words:

Time is basically divided into past, present and future, so lets start with past. Anything which happened doesn’t matter whether it’s known to you or not, it is past. Present is infinitesimal and future doesn’t exist, it’s just based upon the events of past and present. Everything which is happening right now can contribute to the future of anyone. The things someone did in the past, the things someone is doing in the present can play a part in shaping someone’s present in the future including his own present of the future. Future is a projection created by our imagination, knowledge, experiences or by the acts of anyone. When you draw something with a pen on a piece of paper, the things you have drawn is past and the thing you are drawing is present, it’s just all about the touch of the tip of pen to the paper and as soon as it touches the paper present becomes past and future becomes present, that’s how small is the present and all the things you are about to draw is a future. So past, present and future they all exist without the concept of time.

Lets try to go little deeper in this concept. Time is a concept to measure the motion of anything or the change in anything, considering the motion of all particles; the motion of atoms. It’s a concept to measure the motion or the change in the whole universe. How do we measure anything like if we have to measure weight? We just compare it with some kind of standard that we have defined. By comparing something with a particular standard we calculate or measure the unknown things, that’s how we do it. We have created standard to measure things and to measure motion or change we have created the concept of time, like miles per hour, 24 hours is equal to one complete rotation of the earth on its axis, then one revolution of the earth around the sun is equal to 365 days(one year), etc. It shows that when we are dealing with time we are actually dealing with some standard of motion. When there were not any clocks as we have now, people used to measure time with the help of position of the sun and stars. We always felt the need of such concept and it’s a part of our living. If we didn’t have clocks then we would be depending on some other things and we would make some other concept to measure the events, changes and motion. If somewhere in the universe there’s a life then it’s possible that they might have created some other concept as we have created the concept of time. Time is attached with the motion and forces. It depends upon the motion and the forces of atoms, it depends upon the motion and the forces of everything which exist in the whole universe as everything is made up of atoms.

From the above written post, we can conclude that time is just a standard to measure motion and change, a standard created on the base of motion and forces, and that’s why it changes at different points in the universe. Existence of anything doesn’t depend upon the time;  past, present and future are not time dependent. Time is just a concept that we have defined. So I don’t believe in the possibility of time travel; to me the concept of time travel doesn’t make any sense, you can’t go back in the past, you can’t turn an omelet into an egg. However, nothing is sure as reality is too deep and there is no deep reality. Lastly one more thing, we can go to the future and we are going there right now as the present is infinitesimal!
