Take a look at this famous picture.
Did you look at it? Good. Now, I have a question for you. How many stars are in this image?
One hundred? Perhaps it’s a little less, at ninety-two. Or maybe more, at one hundred and four? All of these are wrong.
The Hubble Ultra Deep Field Image has trillions of stars in it.
The individual stars are the shapes with spikes on them, in a manner of speaking. One is at the bottom-middle, another is just above that one, another is towards the top left, and the last is around the middle. Can you see them?
Naturally, to the uninitiated, this raises the question of “What’s all the other stuff, if not stars?” And a brilliant question that is, for we have the answer.
Every single splotch of color, be it round or ovular, red or blue, or any other color, is an entire galaxy, not much unlike our own. Within each of those splotches are hundreds of billions of stars, each with planets in orbit around them. Move to any given galaxy in this image and look out into the night sky (with appropriate equipment, of course), and you can find our very own Milky Way, in an insignificant corner of the sky, undistinguished from everything else.
Is your mind blown? Or, am I full of shit? Feel free to let me know.
[Edit]: I’ve seen some comments pointing out that there are, in fact, more than three stars in this image. My apologies; this is correct. However, my point was less about how many stars were in the image and more about the underlying message behind this—that we are much smaller than we think ourselves to be, and that every single one of those spudgy galaxies may contain life that is similarly looking out into the sky and seeing our very own Milky Way.
I will update the answer with a tentatively “correct” number of stars. However, please don’t let the number subtract from the message of this image.
[Edit 2]: I want to thank all those Quorans who took the time to read this answer. As I write this edit, this answer has 1.2k upvotes (the most out of all my answers, by far), and has 171.6k views. I was told via a notification recently that the answer has even been translated into Portuguese. This honestly astounds me—never did I think that any of my content would reach this level of notoriety. Thank you again.
Keep on thinking,
Joseph
