Alexander at the Gates

Dan Carlin released the third installment of his Alexander the Great series, and it might be the best thing he's ever done.

The conqueror

Mania for Subjugation III picks up with a 21-year-old Alexander launching his invasion of the Persian Empire — the largest the world had ever seen. Over four hours, Carlin fuses military history with psychological portrait: what kind of person leads cavalry charges personally while commanding an army? His description of Alexander as combining "the qualities of a Napoleon with a gladiator" captures something that textbook accounts miss. The series has been building since Episode 71, which traced Alexander's terrifying family dynamics, and Episode 72, which covered the destruction of Thebes. Together, they're the most immersive history education available anywhere.

The universe is weakening

Quanta Magazine published a feature on DESI's discovery that dark energy may be losing strength over billions of years. The instrument produced the largest 3D map of the cosmos ever created, and the data suggests the force accelerating the universe's expansion isn't constant. If confirmed, it would overturn a fundamental assumption of modern cosmology. A follow-up piece explores how this finding aligns with predictions from string theory — a rare case where observation and theory are converging from different directions.

Dostoevsky's prophecy

Philosophize This! released an episode on Dostoevsky's Demons that's sharper than most literary criticism. Stephen West traces how the novel connects belief in God to political ideology: when traditional moral foundations collapse, what rushes in to fill the vacuum? The episode avoids the trap of making Dostoevsky sound like a conservative talking point — instead, it takes seriously the question of what nihilism actually does to a society when it moves from philosophical abstraction to lived reality.

The connection

A young king invading an empire, a universe losing its driving force, and a novelist predicting what happens when a culture loses its foundations. Each story is about what happens when the thing you thought was permanent turns out to be temporary.
