As it pertains to matters of cosmic perspective, few are more eloquent than Neil deGrasse Tyson (NDT), not to be confused with the Canadian television series Degrassi Junior High (which I admit I might have watched). From the Big Bang Theory to the formation of elements to the story of Earth, NDT educates and entertains with the best of them. Along the way, he answers some deep questions. What is Earth’s role in the universe? What are humans made of? Isn’t a cosmic perspective deflating? Here are a few paraphrased take-home messages from the brilliant astrophysicist himself.
What Is Earth’s Role in the Universe?
Earth orbits an average star (the Sun) that is one of hundreds of billions of stars in the Milky Way, which in and of itself is one galaxy among perhaps a hundred billion galaxies in the universe. And there remains a possibility that the universe to which we refer could be just one of an infinite number of universes that comprise a much larger multiverse. In other words, from a cosmic perspective, Earth can be considered a speck of dust.
What Are Humans Made Of?
Four of the ten most common elements (substances made of only one kind of atom) in the universe are hydrogen, oxygen, carbon, and nitrogen. Humans have not been given special treatment. Hydrogen, oxygen, carbon, and nitrogen account for over 99 percent of atoms in the human body. In other words, humans are hardly distinguishable from the rest of the universe. In NDT’s words: “We do not simply live in this universe. The universe lives within us.”
Isn’t a Cosmic Perspective Deflating?
Perhaps to some. Though these are usually the individuals who have misread their own importance. A cosmic perspective may help prevent certain undesirable effects of the human ego, with examples including partisan political rancor and lethal ethnic conflicts.
If you’re intrigued by this type of insight, some of NDTs books might be of interest. In particular, Astrophysics for People in a Hurry is a good starting point. Keep in mind that any book about astrophysics runs the risk of making your brain hurt a little, but with only around 200 pages, this one limits the pain and maximizes the gain. Just be warned, as NDT says, “The universe is under no obligation to make sense to you.”

As a speck in this universe I am truly humbled!
Haha. So are we all!
Thanks for this concise article. I think the deflating cosmic perspective as you succinctly explained it is a great thing, because it can help one take themselves and life a little less seriously, and enjoy it more!
Totally agree! It definitely helps when figuring out what to worry about and what to laugh about.
Atom has lot of power. So is a human speck. need to apply properly.
Well said!
