A book with the idea... 1884 😱
🌌 What If There’s a Dimension We Can’t See?
Imagine living in a flat world with only left, right, forward, and back—no up, no down. Now, imagine a 3D object like an apple passing through your world. You’d only see it as a shape that grows and shrinks, and its “voice” would sound like it’s coming from inside you!
Carl Sagan used this idea to show us something shocking: just as we can’t see “up” in a flat world, we might not be able to see a fourth dimension in our own universe. Could there be more to reality than our eyes can ever detect? https://video.nostr.build/ddd2a4f91a2c4ce84bdcdbf17b567600d59fbe15ad5ed88051b9e5765c21d3c2.mp4
