How much of the universe do we know about?

So, the stars and galaxies and the conventional matter we observe all around us really only compose 5 percent of what constitutes our universe. Our research has revealed to us deep mysteries about the remaining 95 percent, inspiring the title of tonight’s discussion, “The Universe Is Stranger Than We Thought.”

Is there a finite amount of information we know about the universe?

And those limitations — the total numbers of particles and the total amount of energy available in the Universe — means there’s only a finite amount of information we can determine about our cosmos. For the first time, we can quantify that, and begin to infer which things we might never understand.

What’s going to happen when we fully understand the cosmos?
