One thing we know for sure thanks to our technology, what we don’t see, hear, or feel it doesn’t mean that don’t exist. Your mobile phone all the pictures, video, music, communication comes with invisible waves, the electromagnetic waves.
Electromagnetic waves are defined according to our knowledge to different frequencies. Our brain also works in frequencies, studies have shown to function from below 0,1 to 110 Hz and this doesn’t mean we know everything.
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy.Note: What we call as heat it is also an electromagnetic wave.
When we die our brain stops and this electromagnetic energy according the First Law of Thermodynamics has to go somewhere. If already our brain during our lifetime is connected permanently in a certain frequency unknown to us, when the body dies this energy probably will join the frequency which was always connected.
If you think which part of our brain function could be always connected, the best candidate is our conscience, because is the tool which supports our awareness.
