Create a 30-minute podcast script featuring two enthusiastic hosts discussing the origin of the universe. The tone should be fun, lighthearted, and conversational, with occasional humor to keep listeners engaged. The hosts should play off each other's personalities—one being curious and excited about cosmic mysteries, while the other is skeptical but witty, questioning everything. Use relatable analogies (like a cosmic soup or fireworks) to explain concepts like the Big Bang and the expansion of the universe. Avoid technical jargon, and keep the discussion entertaining and accessible. End with an optimistic conclusion, like the idea that we're all 'stardust,' inspiring curiosity about our place in the cosmos. Include an introduction and outro with playful dialogue and optional music cues.
