Is Dark Energy a Part of the Pie Chart of the Universe?

I am well aware that doing our best to understand how the world works can lead us to making statements that seem bizarre and way out and sensational, right? But if we think they're true, we should make them anyway. I also don't agree that it's make sense to talk about these things as illusions. To me, when you say something is an illusion, it's a trick. And i think that things like consciousness and free will and chairs are there. They are not illusions. Why? Because they give us a handle on reality. because they help us understand what is going on and make predictions. That's the criterion for being real.
