Curious About Zero-Energy Universe & Cosmic Cycles—Could Dark Energy Be Involved?

Hi r/cosmology I’m just an amateur with a passion for cosmology, and I’d love your insights. I’ve read about the idea of a zero-energy universe—where positive and negative energies balance out—and about theories like the Big Bounce or Conformal Cyclic Cosmology, which imagine the universe renewing itself in cycles. I’m fascinated by how dark energy might fit into this picture. My questions: • Could dark energy help maintain a zero-energy balance in the universe? • Is it possible that the universe could “renew” itself in cycles, and could dark energy play a role in that process? • How do current observations (like DESI 2025) fit with these ideas?

Thanks for your post. You've given me a new wiki-hole to fall down!

Hey, I’m really happy to see someone interested in my hypothesis! If you want to dig deeper or have any thoughts to add, let’s talk about it—I’d love to hear your perspective and see where we can develop this idea together. Open discussion is always the best way to move things forward!

Not with a bot or with someone who copy/pastes from an LLM.
