  🌊 The Sapphire Heart: What If Australia Was 1.5x Larger with a Giant Inland Sea? Welcome to another journey in speculative geography. When we think of Australia today, we picture a vast, arid "Red Centre" surrounded by coastal fringes of green. But what if the continent's geological destiny had taken a drastically different path? Imagine an Australia $1.5$ times its current size , making it larger than the entire continent of Europe. Now, instead of a sprawling desert, picture a massive body of water—a remnant of the ancient Eromanga Sea —beating like a "Sapphire Heart" right in the middle of the continent. Let's explore the breathtaking landscape of this expanded, water-filled mega-continent. 1. The Scale: A Behemoth of the Southern Hemisphere At $1.5$ times its normal size, this alternative Australia dominates the Southern Hemisphere. The coastlines stretch further out into the Indian and Pacific Oceans. The sheer mass of this continent means that cro...

  🌱 The Emerald Citadel: Life on the Expanded Dokdo In our previous post, we imagined a Dokdo with twice the surface area—a massive "fortress" of rock and plateau. Today, we explore the biological consequences. If humans never set foot on this island, what would live there? Staying grounded in realistic science, here is the speculative biology of the 2x Dokdo . 1. The Green Core: Beyond Salt-Tolerant Grass Currently, Dokdo's vegetation is dominated by hardy, salt-tolerant plants like sedum and aster . In a 2x scenario, the "Inland Buffer Zone" changes everything. Shrub Forests: With a wider plateau on Seodo , the center of the island would be far enough from the coast to escape the constant "salt rain" of sea spray. This would allow for the growth of denser shrubbery and even small, wind-resistant trees like the Japanese Spindle tree ( Euonymus japonicus ) to form thickets. Soil Accumulation: A larger, flatter surface means less soil is washed a...
