"Everything we call real is made of things that cannot be regarded as real" Niels Bohr.
Now, let me explain, of course matter exists. The notebook you use to write down your thoughts, the apple on you dinning table or the pillow you rest your head on at night, they are all material things that we use in our every day life, right? However, the physical world around us turns out to be anything but physical.
After reading this article you might want to discard the idea of reality as you know it.
Let's look at the structure of the world
Everything around us, ourselves included, are made out of atoms. And quantum physics has shown that if you look closely at the structure of an atom it is essentially made up of vortices of energy, constantly vibrating. So, if we were to eliminate all the empty space in an atom, humans would be reduced to the size of a dust particle. Humanity would fit in a sugar cube.
Which means that matter is only energy.
Then why can we touch things if they're just energy? Shouldn't we be able to cross walls? Well, let's take a fan, for example: when it's working there is no way you can stick your hand into it, the blades wouldn't allow you to do so. Although when it's turned off and the blades are not moving, you'll see that there's plenty of empty space. It's the same with atoms, they're in constant motion, that is why the world feels solid to us.
The theory of free energy
Nikola Tesla was one of the most important scientist in history. And he knew that space wasn't empty but, in fact, was full of kinetic energy.
"It is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature."
Nikola Tesla (February 1892)
What this means is that we can stop using fossil fuels, which are destroying the Earth (and are incredibly profitable for private companies), and start using the resources the Earth is providing to us.
