Our Place in the Universe: A Sense of Scale
Do you think that the sun is far away? Most people would… but consider this:
There are 100 billion stars in our galaxy alone, and there are 100 billion galaxies in the observable universe (and that’s just the area of the universe from which light has had time to reach us from, it could be BIGGER than that).
The distance from one side of our galaxy to the other is 10 billion times the distance from the Earth to the Sun, and the distance from our galaxy to our closest neighboring galaxy is 165 billion times the distance from the Earth to the Sun.
And, finally, the diameter of the observable universe is 1 million billion times the distance from the Earth to the Sun.
We exist on a scale that unfathomably tiny compared to the large-scale universe. Our comprehension of the cosmos is equivalent to beings that exist on protons comprehending the physics of our everyday lives. I feel so lucky to even begin to understand the large-scale universe in which we live. We are tiny. But we are special.
The distance from the Earth to the Sun is 150 million kilometers.
