Science is unsuccessful where scientists refuse to do or accept research into areas that they have rejected at a personal level, and indeed ban from their midst other scientists working in those areas.
There is no absolute objectivity in science because it is made up of the findings of human beings, none of whom are perfectly objective. The presumed objectivity, holds back research into areas people think, both atheist and theist, should be reserved to “faith.”
Communication between people in Time and people in what we call “afterlife” is one of those areas. The ability of a person to affect matter solely by intent is another. I’ve seen scientists, top scientists, skew their own data purposely because they could not explain their results without resorting to the influence on their instruments coming from a non-local source. Not extraterrestrial, but outside of Time/space.
In the Denver Museum of Science and Nature or whatever they have now named it, in the three story entranceway, there hang two casts of a creature that never existed. Mostly it did, as the casts were taken from a very complete specimen of plesiosaur. You can see a pic of it here:

The chief preparator, had a poor grasp of evolutionary theory and his own idea how the creature should have lived. But the original cast, made from the specimen, didn’t fit with his ideas so one day he walked into the lab with a sawzall and simply cut off about a third of the ribcage of both of the casts being mounted. Both of those altered casts are still hanging in the museum as far as I know.
GIGO. Science is only as good as the scientists who practice it. There is nothing magical about God or Heaven or the afterlife or any reason not to pursue knowledge of these as assiduously as we do anything else.
