Psychological Point of View
After researching some days on the topic of 'Rebirth', the strongest point I caught to support the rebirth phenomenon is that in most of the cases, past life memories tend to appear at the age of two to six, after eight the experience begins to disappear, and with few exceptions, vanishes completely in adolescent.
I believe all children have past life memories either directly or indirectly, mostly indirectly. Let me clarify it. You may have wondered how a one year child is aware of the fire. You may have noticed how a child is aware of the height of a place. More amazingly, how quickly a child learns language. All it's doing is with past life experiences. After age of eight, the child would have developed self controlling on such things. Then it begins to forget the past memories and earns the future experiences. But some continue to remember past life memories even in adolescence. It is because there is always a special purpose behind his/her birth.
Theory of Cause and Effect
Now let's talk about Science. What are the scientific arguments that can take side of Rebirth? I would like to begin with an established theory of Physics, i.e., 'the theory of causality' which is simply known as the 'theory of cause and effect'.
I don't want to spend digital inks here for explaining in detail what the theory of cause and effect is. Because it is not our mainstream topic today. I just give a funny example that will vividly clarify this theory. When a girl and a boy marry, they will give birth to a baby. This is exactly the theory of cause and effect. Here you can not expect effect without cause and when there is cause, there must be effect.
Let me open the pages of Philosophy. You will wonder if you consider the fact how our current actions affect our coming future. You will reap what you sow. Do good , outcome will be good. Be bad, bad will happen. In my whole life I have noticed it. But there is a question what if a person dies without facing the effects of his/her good or bad acts? It's simple. To maintain the cycle of cause and effect, nature deals with the thing like rebirth.
Quantum Mechanics
Another mechanism that can strongly advocate rebirth is quantum mechanics. What is this? This is study of the universe in smallest scale like atom or sub atomic particles.
There are around 100 trillions cells in our body. Each cell consists of 100 trillions atoms which were formed millions of years ago, before we were born. More interestingly, they will remain in the universe even after we die. They can just change their form. They can never be destroyed. There is an amazing belief that our consciousness or soul exists as energy at a sub atomic level. It means our consciousness or soul is simply a packet of information stored at a quantum. After death, it comes out of the body and enters in another which is called rebirth. Max Planck, a Nobel Prize winner Physicist and the father of quantum theory has said, ''I regard consciousness as fundamental. I regard matter as derivative from consciousness. We can not get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness.''
Finally I want to pour my personal thought that our consciousness or soul might have begun with the event of Big Bang and then everything we experience is happening as per the set up cycle. So we can say we were, are and will be in all times till the universe exists. What do you think? Let's discuss in the comment section.
