Thoughts About Light and Stars

I wrote this a couple months ago and posted it as a note on Facebook. These are just some things I like to think about. Check it out. =) It will definitely make you think. You just might like it. ;)




I'm homeschooled, so instead of going to school every day, I end up at home doing hardly anything. Which is pretty cool because it gives me time to think. (Which is something that you NEVER get to do at school.) ;)
I got up this morning, cooked myself some food, watched a couple episodes of The Big Bang Theory and I Love Lucy and then went and sat on my bed for about half an hour doing absolutely nothing.
That might not sound very productive, but it gave me time to think.

I started thinking to myself about light. I remembered reading in one of my science books about photons.
Our universe is made up of very strange, unexplainable things but nothing is as strange as light. Light comes from the sun in the form of particles that are called photons.
A photon is an elementary particle, the quantum of the electromagnetic field and the basic "unit" of light and all other forms of electromagnetic radiation.
Light travels at 670,000,000 miles an hour.
Light does not follow any of the rules of our neutonian understanding of the universe.
When it comes to light, there is no A+B=C. Light just does it's own thing.

I started thinking about stars and what an amazing creation they are. Scientist have agreed that our universe has over 100 Billion galaxies.
Each of those galaxies has somewhere around 100 billion suns.
And each of those suns has at least 100 billion stars.

Stars are everywhere and they do such amazing things.
There are stars that we can see from the earth that are hundreds and thousands of light years away. So when you look into the sky and you look at a star that is a thousand lightyears away, you are actually seeing something that happened a thousand years ago, because thats how long it took the particle of light that you're looking at to get to you.
When you look at a star that is a thousand lightyears away, you are looking a thousand years into the past, because what you are seeing actually happend 1,000 years ago.

The closest star to our planet is technically the sun. The sun is approximately 8 light minutes away from the earth or (.000016 lightyears.) This means that it takes light from the sun 8 minutes to reach the earth.

Genesis 1:14-19
14 And God said, "Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, 15 and let them be lights in the expanse of the sky to give light on the earth." And it was so. 16 God made two great lights—the greater light to govern the day and the lesser light to govern the night. He also made the stars. 17 God set them in the expanse of the sky to give light on the earth, 18 to govern the day and the night, and to separate light from darkness. And God saw that it was good. 19 And there was evening, and there was morning—the fourth day.

So on the fourth day, God created the stars.
Besides the sun, the closest star to the earth is Proxima Centauri and it is 4.21 lightyears away from the earth.
So following this theory, though the stars were created on the fourth day, they would not have been visible to man on earth until four years after the earth was created.

So were the stars visible from earth as soon as God created them? Or on the fourth year after the earth was created, did the stars slowly begin to appear in a wonderful, beautiful display of new lights in the sky?
It's definitely something to think about.

Anyways. Slow day. I just thought I would write down some thoughts.
Be sure to comment! =)
Thanks!
