What's Beyond the Observable Universe?

We have no idea what's out beyond the e the observable universe. Like photons that were created at t equal zero, the beginning of the universe, 62 billion light years away, will never reach us. As time goes on, you can be closer and closer to us. Shoot a flashlight at us, and it will never get to us because this expansion is accelerating. Idea that whole part of the universe, maybe the rest of the entire universe, is basically dark to us, right? It's invisible lakn.
