Okay, so this is kind of a pseudo-science, but if we as humans have learned anything about science and nature, it's that we shouldn't be so quick to laugh at ideas that sound outrageous at the time.
There are claims floating around that ordinary water has memory. I don't know how that's possible or what that means exactly, but just imagine for a moment if scientists started researching into it.
WHAT IF they unlocked it? What if they found a way to not only access the memory inside water, but began storing it there, too?
How would this affect ordinary life? How do you think the governments would use it? What do you think we could learn about the origins of life? How would this change space travel? Time capsules? Cross-cultural communication? Would there be archives of every point in history? What if one point in history was missing? Why might that be the case?
It's not something to revolve an entire story around, necessarily, but it's something to think about if you're writing a distant future or sci fi novel.
Just a little something for your Monday mind to munch on.
