There are approx. 200 to 400 billion stars in the Milky Way.
Difficult to imagine? Let's start small.
What does a billion of anything look like?
Let's look at the bag. It holds bird seed
Look for the bag in Part 3 here.
--------------------------------------------------
- Now, look at this galaxy. It has 200 to 300 billion stars.
- There are billions of galaxies! With billions of stars and that is just what we can observe with the current technology.
- A billion billion is a quintillion more in Part 4 here and there are about 400 billion x a quintillion stars in the known universe.
- Something to the power of 10 to the 24th. It blows your mind. more in Part 3 -Item 2 here
- It isn't just the number of stars, and the enormous scale and size and distance. It's the amount of time that each galaxy is 31 million light-years away
- In the amount of time, it took for the light from that picture to reach us, entire species could evolve on planets and develop into a spacefaring galactic civilization; empires could rise and fall, then fade into dust, and be lost in the sands of time, without us ever knowing.
- Sci-fi uses such an idea often.
- And that's just the 31 million years it took for that light, which is a drop in the bucket of time that this galaxy has had to create life over many many billions of years.
