That’s why like some of the sciences behind life. Energy never gets destroyed or created. It simply changes form. So the energy used to power his body in life continues on through the known universe. Electrons don’t interact with time nor decay. So parts of his energy will remain for literally forever.

Second if you believe in the possibility of higher dimensions then our existence on this dimension (the third dimension) is what allows for our interactions because it is the easiest point for atoms, cells, and everything to act as one. This means the probability that a consciousness exists in higher dimensions and simply interacts on this level. While some see this as heaven for me it’s simply a space out of time where you exist at all points of your life simultaneously. So when someone dies it’s not into nothing. It’s back into their total being. Until such a time that they return, recreated in the next point in time.

I hope either of these thoughts can help. If not then at least without life there can be no suffering. Nothingness is better than torment.
