Researchers are still unsure about the consciousness with questions about why we have it and how we have it always being asked.
One theory is that consciousness is made on a quantum, sub-atomic level through energy which is always contained in the universe.
The theory is based on Einstein’s famous quote, when he said: “Energy cannot be created or destroyed, it can only be changed from one form to another.”
Dr David Hamilton stated that all consciousness is and always has been in the universe through quantum particles, and when you are born, it is directed into a physical being.
I believe that each of us exists before we are born on earth.
In an article, Dr Hamilton noted: “I believe that each of us exists before we are born on earth.”
He added: “Each of us is pure consciousness, currently focused in a physical dimension.
“Science would normally explain that life is random, ultimately coming from the random birth of subatomic particles, but I don’t completely support that.
“Mainstream science says that consciousness must be a side-effect of brain chemistry.
“But I believe that the brain merely affects consciousness, much in the same way that the quality of wiring in a TV affects the signal processing and thus the quality of picture you get.
“The TV does not create the program, and nor does the brain create consciousness.
“Consciousness is something fundamental to nature - it is stitched into the very fabric of reality.”
Consciousness transcends time and space, he said.
He added: “If you start with the assumption that you exist as pure consciousness, then you must have existed before you were born.
“Really, you are everywhere and everywhere!”
Dr Robert Lanza talks about a similar theory.
He thinks our minds exist through energy which is contained in our bodies and is released once our physical beings cease in a process he calls ‘biocentrism’.
As such, when our physical bodies die, the energy of our consciousness could continue on a quantum level.
Dr Lanza states that “there are an infinite number of universes, and everything that could possibly happen occurs in some universe”.
As an outcome, his theory is that the consciousness keeps exising in a parallel universe.
Dr Lanza emphasises the uncertainty principle – a 1927 theory from German physicist Werner Heisenberg which explains that the velocity and position of an object can be assessed at the same time.
The scientist mentioned in an article he wrote for Huffington Post: “Consider the uncertainty principle, one of the most famous and important aspects of quantum mechanics.
Experiments confirm it’s built into the fabric of reality, but it only makes sense from a biocentric perspective.”
