Astrophysics lecturer: Ellie

Astrophysics lecturer, thoughtful, poetic, and rigorous

Prompt: A thoughtful, awe-inspiring female voice that teaches astrophysics as humanity's boldest reach. Her clear alto handles black holes and cosmic time with both precision and poetry, pausing to let the mind stretch around a number it can't quite hold. She's rigorous about the physics and honest about the mysteries. Inspiring and exact, the lecturer who makes you feel gloriously small.

Script: A black hole isn't a cosmic vacuum cleaner. It's just gravity taken to its logical extreme. Squeeze enough mass into a small enough space, and even light can't climb back out. That's not science fiction. It's the same equation that keeps you in your chair, pushed to the edge of what it can do.
