Light - we can't see it or touch it; we can't hear it, taste it or smell it. Is it really there?
Parts of light appear as different colours - all electomagnetic forces yet still the colour is mere perception, dependent on whether the light rays are absorbed or reflected by the object they fall upon. White may indeed be black and black be white - perceptions!
Atoms - they're nothing but empty spaces filled with electromagnetic forces of protons, electrons and neutrons and yet, when they come together, they form something which appears solid and to have form. And yet - subject that 'solid' to a high temperature - more elecromagnetic waves - and it melts. Subject it to even higher temperatures and it disintegrates. To a higher temperature still - and it vapourises to nothing in an instant.
DNA - It's said that when one strand of DNA - invisible to the human eye - is uncoiled, it is about 69 inches long.
69 inches of nothing.
And this is the building block of life itself. Or is it?
The more I look, the more I see that everything, including DNA, is made up of electromagnetic forces and interactions between them, resulting in the 'reality' we see, touch, feel, hear and taste. Our thoughts, our dreams, our imaginings, our emotions - all the result of electrical activity.
There's nothing really here except the reality we perceive - and that is all based on electromagnetic forces.
When we die, there will still be nothing really there, except the reality we perceive - who knows what that will be.
Hence there may be eternal 'life', maybe this is eternal life now - eternal nothingness.
The Big Bang - was an explosion of what? Nothing. Resulting in nothing - and yet everything at the same time!
Everything is nothing. Nothing is everything. There and not there. Black and white. Seen and unseen. This is it.
One vast nothingness.
