CHANGING THE PAST


Time is a very interesting quantity and time traveling has been a hot topic since years now. Each one of us atleast at one point of time have thought of going back to time to rectify our mistakes. But  by doing that will we really succeed? Time is a unidirectional quantity and it'll always move forward. Einstein's theory of relativity states that in order to travel back in time one has to travel at a speed faster than light. But to accelerate a mass to that speed would require infinite energy which is not possible. Therefore time travelling is considered impossible. To travel in time one has to somehow curve the space-time. But, let's now say that somehow you found a way to break time barriers and decided to go back in time and change something. When you will land yourself in the past, the past will already have a version of you. That means once you accomplish your objective there's no point in staying in the past as that timeline already has a version of you. Now let's say you decided to give a visit to your childhood to change something. When you change something in your past ,only the time of that particular universe will change. In other words  by changing something by traveling back to your past will only change the future of that particular timeline but when you will come back to the present you will again find yourself in the exact same position. For example:- let's say a man travelled back to time and killed a tiger that was about to kill his friend. Now by doing that he managed to save his friend only in that particular timeline because when he returns back to the present his friend will still be dead who was already killed by that tiger. Everything in nature comes in pairs, for every negative there's a positive, night and day,male and female and so on. Our decisions comes in pairs too. For a 'yes' there's a 'no'. For instance if you select a red car over the white, the red car will become your reality in this timeline and the white car in an another. It all depends on what you accept. That is why when you travel back in time you will land in one such timeline and your actions will only change the course of  events for that particular timeline instead of the present timeline. In simple words time travel can be considered as a bridge that connects two different timelines. So, the next time you think of cruising through time think for yourself whether it's worth it.

COPENHAGEN INTERPRETATION OF QUANTUM PHYSICS

‌"What we know is a drop. what we don't know is an ocean" this famous quote was stated by the renowned physicist and scientist Sir Albert Einstein. Science in this new age can be classified as classical and quantum. Classical science is very different from the quantum level. When we look around our surroundings we see the world as it appears, in a simpler manner. We behave with our general perception to draw out our opinions or to explain the behaviour and nature of the universe. Science is a collection of explanations and also a set of arguments that refute these explanations. As science kept on evolving with the evolution of time, so did it's theories. The nature of classical science is very appealing to the general mind as it perfectly fits the common perception of the human brain. For example:- if we know the speed of a car and also the distance it will be travelling then we can easily find out the time. Similarly, if we know the speed of revolution of a planet ar

Time

Since our childhood we were being given lessons on time. Our elders,parents,teachers literally everyone advises us to work on time,to sleep on time,to eat on time in short to maintain time. As we gradually grew up we realised that actually we  have become a slave of time. We do everything, decide every move,take actions all according to time. Just imagine a day without time. All the clocks in the world suddenly vanished. The lives of the entire population around the globe would come to a still. It's weird Right?? Yes,it is but have you ever thought what is time? What is it nature?? Well, first I thought that time is nonexistent. It's just an imaginary concept designed to maintain order  and planning in our lives. A calculation with reference to the distance and motion of the stars,planets and breaking it into fragments called time. But, gradually I realised that I was wrong. Time do have an existence, its not about just some calculations but its all about illusion. Even Sir Alb

The fifth force

Since inception, the human mind has continually stared at the nature of the things that encircles its existence. With time it has made various breakthroughs and evolved from it. These breakthroughs come in all shapes and sizes. Lately, the discovery of a new force made headings in many publication and articles. The fifth force can be considered a major breakthrough. But first, let us understand what makes this discovery so important. The scientists have a book that they use to explain everything that surrounds us or the nature of the things that surrounds us. This book in the simple sense describes the ingredients that make up our universe. The book is called the standard model of particle physics. This model has two categories, fermions and bosons. Fermions are the elementary particles that make up matter. They are further divided into quarks and leptons. Just like atoms are made up of protons, neutrons and electrons similarly protons and neutrons are made up of quarks and electrons f
