This is the real issue with these so called discoveries: nothing can be proven, except by the mere words of those who claim it exists. If someone else other than NASA scientists has peeped into those telescopes and seen man-like figures or animals moving around in another place millions of miles away, it would be believable. If they can really see those things, they should be able to photograph them. That would be evidence.
Heaven and hell are part of those galaxies.They are deliberately made inaccessible to man irrespective of the complex technology existing. One is very green with beautiful trees, shrubs, rivers while the other one is fully covered by red hot sapphire, hotter than magma.
No man will ever see or set foot in any of those two galaxies before the return of our saviour Jesus Christ.
I dont think heaven or earth are physical places, or at least, places that can be perceived physically. I think theyre more spiritual and thus not even physical eyes cant discern the same
