what are quantum theorys
Answers
I did my course and also three years research at my visit to IIT kanpur about three years ago !
Quantum Theory in simple words is just a branch of science that aims to research and experimentally unfold the actual nature and behaviour of tiniest particles that make up matter.
In the early 20th century when there were many researches going on different small sub atomic particles like neutrons, protons and electrons, etc.
In an experiment, the Young's Double Slit experiment, an illogical and very unintuitive conclusion was observed which actually blew everyone's mind and hope fully also gave a pretty interesting answer to the debate over the wave and particle nature of different sub atomic particles.
I recommend and suggest you to go on and read almost everything about Quantum mechanics on web and YouTube and wherever possible !
You'll be amazed at the beauty of the nature created by God !
Alright ! However, let me tell you what my research was about !
I did my research with Professor Raja Srinivas who was a computer science assistant professor at IIT kanpur.
We did work on publishing papers on Quantum Computing and Quantum Entanglement because I usually loved more of Computer Science.
Hope this helps you !
Jai Hind ! and Namaste !
In most simple terms, Quantum theory describes the nature and state of matter and energy at the atomic and subatomic levels. Basically, there are two implications of quantum theory:
1. Multiverse theory
2. Copenhagen interpretation
Multiverse theory: As much as a possible number of states and positions an object can hold, the universe of that object creates a series of the parallel universe equal to the number of positions in which objects exist. Suppose, If an object on our Earth exists in 3 states and 3 positions, then our universe creates a 3 parallel universe just like the universe in which that object exists. So according to this theory, an Infinite number of the parallel universe exists.
Consider the following example:
- Suppose you are travelling by train in this universe. On that train, you are browsing on your phone and after using a phone for some time, you look outside your window.
- So, According to Multiverse theory, an infinite number of "You" are present in an infinite number of parallel universes. But you are in not the same position in every universe.
- In one universe, you are maybe travelling through the bus and you have a laptop or any other gadget in your hand, in one another universe, you are maybe travelling through the airplane in which you are watching TV. In one universe, maybe your travelling has been canceled. In this way, infinite numbers of positions and the existence of matter are possible.
Copenhagen interpretation: According to this theory, An object doesn't exist unless anyone sees it. i.e. objective reality doesn't exist. For any particle or wave, we cannot assume the properties and state of the matter until we measure it. This is also called as "Superposition". In most simple languages, we can state Copenhagen's interpretation as "Matter exists an infinite number of states and positions if no one is looking at it."
Consider the following examples:
- Imagine a forest through which you are walking. And suddenly you saw an apple falling from the tree. When the apples fall on the ground then you hear a sound because it makes a sound on falling which is obvious.
- Now suppose you are not walking through the same forest at the same time. So, According to the Copenhagen interpretation theory, when the apple falls on the ground it really doesn't make any sound.
- Another example: Imagine a cat in a cardboard box. In that box, you have kept some poison for the cat, such that if the cat will eat or drink it, the cat will die. So, after an hour, you came near the box and see the box, you see a cat died in that box. But according to quantum theory, If you will not look at that box, then the cat still exists and alive.
Possible reasons according to scientists for these theories:
- One theory describes that Our earth is in a simulation. i.e. We are in the video game of super-advanced civilization. This has been theoretically proven.
- Last year, A video game company named "Rockstar games" released a game name "Red dead champion sea". In that game, the graphics used were just like real life. If we play that game virtually in very high quality then we experience just like travelling through the real world. So, According to quantum theories as we know that infinite numbers of universes possibly exists.
- So, there might be a super-advanced civilization that is playing a video game of which we are just a part. As they are super advanced, they might have high-level graphics, audio and etc.
- Another possibility: When our universe was formed 13 billion years ago, then the universe was expanded so quickly. It was so quickly than the speed of light. And we all know that, Before this expansion, our universe was just present in compressed photons and electrons.
- Some scientists believe that, At the initial stage, As the expansion was occurring so rapidly, the infinite numbers of different universes may have been formed. As the expansion was just started from one single photon, so the all universes formed might be formed very exactly to each other and they may have interconnected.
You must know about this:
In Quantum physics, Mechanics, Computing, etc. The study of any particle of matter is done at the subatomic level. We all are aware of the structure of the atom. Inside a nucleus, there are protons and neutrons. And electrons are revolving around the nucleus. But have you ever thought about "what's inside the proton? electron? neutron?". There are Quarks inside the protons, neutrons, and electrons. These Quarks are nothing just a wave. So technically, Everything around us is a wave. In fact, anything we see around us is present in the form of waves. We cannot see it because the wave is formed to Quarks, Quarks to atoms, and atoms to particles.
"Quantum physics is so advanced and very hard to understand. Still, scientists are trying their best in the research of Quantum physics. In future years, we would surely get clear explanations of Quantum theories."
