How Big is Our Universe?


| 2 Comments
I've often found myself curious to know how big the universe is.
According to NASA, beyond our own galaxy lies a vast expanse of galaxies. The deeper we see into space, the more galaxies we discover. There are billions of galaxies, the most distant of which are so far away that the light arriving from them on Earth today was set out from the galaxies billions of years ago!

This is a picture of The Ultra Deep Field, described as the "most amazing photograph ever taken," revealing over 10,000 galaxies in that very small part of the sky that are older than 10 billions years!

As I read about the universe and sat down to write this blog, I remembered something my mom always tells me "you're not the center of the universe." I admit that there are time where I feel like the center of the universe--as if things should go exactly the way I want them. But it's crazy to learn that we are not near the top or center of anything. We are a mote of dust on a speck of dust spinning through an endless universe. How can our consciousness not be changed by this? I am humbled, but at the same time exhilarated. We are all a part of this amazing universe and this sacred mystery is a part of us.
Here is a really fascinating link to NASA findings. and below is a video that tries to give an idea of how big the universe is. I say, "tries" because I believe the size of the universe is beyond any human's comprehension.

My speculation is that there has to be life form out there it is just virtually impossible for NASA to travel those light years to explore it. What do you guys think?

Shouldn't there be an episode of "The Big Bang Theory" about this?? You get that pun I just pulled there? Since the universe was created by a phenomena called the Big Bang and your post is about the universe in general! Well anyway, after I took ASTRO 001 my freshman year it really increased my knowledge of the astronomical universe and the class really makes you think after it's over. Like how the majority of the universe is "dark matter" and how small the Milky Way galaxy is in retrospect to the the massive astronomical universe itself. If I'm not mistaken, I think my professor actually used this exact same video to show us a quick example of how big the universe is on our lesson on galaxies.
