What is the natural universe?

1. The world and its naturally occurring phenomena, together with all of the physical laws that govern them. 2. Living organisms and their environments.

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.”

Are humans a part of nature?

Nature, in the broadest sense, is the natural, physical, material world or universe. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.

Do we really know everything about the universe?

Even though we don’t know everything, there are enormous sources of knowledge that have empowered us to draw far-reaching conclusions about our Universe. We know what it’s made up of in terms of matter, energy, radiation and so on.

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?

In a very short time we’ve come a long way in our understanding of how the world works. But what’s going to happen when we fully understand the cosmos? It took 3.8 billion years, but we got there in the end. For most of the history of life on Earth, life was pretty dull. Then humans evolved, and things got interesting.

Is there an infinite amount of matter in the universe?

No matter how quickly the fabric of space expands, nor how fast the speed of light is, nor how much time has passed since the Big Bang, none of these properties are infinite. Therefore, we can only see a finite distance away, and there’s only going to be a finite amount of matter contained within the visible Universe.
