Thank you, Esther, for writing this article.
I am a structural philosopher and I like science very much. I hope you are interested in reading my article about the location of the afterlife -- more or less right here, with our planet, our solar system and perhaps even as large as our Milky Way. But... definitively not anywhere outside the Milky Way.
Our scientific reality is that we are captured in a specific setting, and even the non-material aspects of life are found here, not anywhere else.
The Hereafter is Still Here:

I hope you recognize the structural attempt to keep this as scientific as possible.
