0:00.0	Hello, SFIA audio listeners.
0:02.5	In this month's Nebula exclusive, big alien theory,
0:05.2	we're asked at the reason alien civilizations might be rare
0:08.0	is because most aliens are huge.
0:10.5	To hear it and every episode early and ad-free,
0:13.3	plus hours of bonus content,
0:15.1	check out go.nebola.tv slash Isaac Arthur,
0:17.8	and use my code, Isaac Arthur.
0:21.0	The universe may offer us barren worlds, but with science, ambition, time, and sheer willpower,
0:29.1	we can sculpt them into paradises.
0:33.7	The cosmos teams with planets, trillions upon trillions, but almost none are suited for human
0:40.3	life. Even those that seem close, Mars, Venus, or distant exoplanets lack the delicate
0:46.6	balance of atmosphere, temperature, gravity, and resources that make Earth a crater for life.
0:53.2	If humanity's expand beyond our home world, we must become not just explorers but world builders,
0:59.2	reshaping alien landscapes into thriving new homes.
1:02.9	Where nature offers only dust and shadow, we shall leave light, warmth, and the indistence
1:08.8	of living things.
1:10.8	Terraforming is the grand endeavor of transforming entire planets, moons, or other celestial
1:16.9	bodies into environments where Earth life can flourish. It is the ultimate feat of engineering,
1:23.6	requiring vast energy, patience, and technology to alter atmospheres, hydrospheres,
1:29.9	climates, and even gravity itself. The process may take centuries or even millennia,
1:36.0	but in theory it allows lifeless or hostile worlds to be remade into lush living habitats.
