John Archibald Wheeler

John Archibald Wheeler was a prominent American theoretical physicist known for his work in relativity, cosmology, and high-energy astrophysics. He contributed significantly to the understanding of black holes, famously coining the term "black hole" itself. Wheeler explored concepts like the "geometrodynamics," which connects geometry to the physics of spacetime in general relativity. He also investigated the role of observers in quantum mechanics, suggesting that "the universe is made of stories, not atoms." His ideas have influenced modern physics and our understanding of the cosmos, bridging gaps between abstract theory and physical phenomena in the universe.
