Before instruments extended our vision, the universe was understood through naked-eye observation—the Sun, Moon, and five wandering planets set against a backdrop of stars that sometimes fell.
Good thinking isn’t just about asking big questions like the Fermi Paradox—it’s about recognizing the biases that shape our answers and staying open to possibilities far beyond our current understanding.
ΛCDM remains the leading cosmological model because our current best measurements indicate gravity is not strong enough to stop the universe’s expansion.
Done. Refresh for another set.
