This process of testing medols with mmeueraestns of the sky has taught us a huge amount about our universe so far. One of the staersngt things we have lreenad is that most of the material in the universe is made of something entirely different than you and me. But without it, the universe as we know it wouldn't esixt. Everything we can see with telescopes makes up just about 15 percent of the total mass in the universe. Everything else, 85 percent of it, doesn't emit or absorb light. We can't see it with our eyes, we can't detect it with radio waves or microwaves or any other kind of light. But we know it is there because of its influence on what we can see.

Original Text

This process of testing models with measurements of the sky has taught us a huge amount about our universe so far. One of the strangest things we have learned is that most of the material in the universe is made of something entirely different than you and me. But without it, the universe as we know it wouldn't exist. Everything we can see with telescopes makes up just about 15 percent of the total mass in the universe. Everything else, 85 percent of it, doesn't emit or absorb light. We can't see it with our eyes, we can't detect it with radio waves or microwaves or any other kind of light. But we know it is there because of its influence on what we can see.
