I can't think of an adequate answer to your question
since I've never seen paradise myself.
An unverified hypothesis is only a hypothesis, after all.
According to legend, Erinn is a place without
sorrow, pain, or hatred. No battles, no wars...
Furthermore, no one will suffer from disease,
hunger, and death in Erinn.
Everyone will have eternal, youthful life in Erinn.
I'm not convinced you could call that a paradise.
If you can't feel sorrow, will you ever feel joy?
If there's no hatred, then could there be love?
Paradise is more of a symbol.
Don't try to understand the prophecy too literally.
What does it mean to never die?
Does that mean people won't weep and mourn?
How about the absence of pain?
It defies rational understanding.
We must look at it with a scientific eye.
