A year and a half ago I wrote, ‘Limits of time, space, and intelligence‘ where I stated,
We are not alone in the universe. Our insignificant planet, in an insignificant solar system, in an insignificant galaxy, in an insignificant part of the universe, can’t be the only place intelligent life exists. So where are the aliens? Why haven’t we discovered them or why haven’t they discovered us?
Yesterday breathtakingly beautiful images were released from the James Webb Space Telescope.
The 6-pointed, flared stars are just that: stars. They develop those flares as a byproduct of glare and the design of the telescope. But every other glowing ball or disc is a galaxy. A galaxy with billions of stars inside of it. That’s so hard to fathom. Furthermore, the first of the 3 images above is a section of the sky that, if you held a single grain of rice at arm’s length away, the rice would cover the area of sky that image is looking at.
Some of the distant blurs are actually galaxies that formed near the start of the universe. The light we see is not just millions, but billions of years old… almost 10 billion years before our solar system was even formed. Many of these really distant sources of light might no longer exist, but it would take another billion plus years for us to even know, because the light from the catastrophic end of the galaxy won’t reach our planet until then.
I’m convinced that if so many galaxies exist in one tiny part of the sky, each with billions of stars, some of them must contain intelligent life. Our Milky Way galaxy alone has somewhere between 100 billion and 400 billion stars. Even if intelligent life is so rare that we are the only ones in our galaxy, the odds that we are the only ones in the universe would be greater than someone winning a lottery daily for 20 days. (I’m making this figure up, I didn’t do the actual math, but I think that’s a low estimate.)
I still don’t think we will learn of intelligent aliens in the next hundred years, but with new high definition images coming from the James Web telescope, we can peer further into our universe. We can marvel at the vastness of space, the variety of galaxies, and even find out more about possible life-sustaining planets. We might not be able to find intelligent life, even knowing it’s likely out there… but we will be able to look deeper into space, and farther into to past of our universe… and that is both beautiful and exciting!
