They are 300 million light years away so this picture actually occurred at the tail end of the Carboniferous Period.
I'm trying to remember what I was doing during that period.

I hate to split hairs here but.....
Someone saying the answer is 10.58, and you saying the real answer is 10.577.....that's splitting hairs.
the Earth has roughly (and we're speaking very roughly here) 7.5 x 10^18 grains of sand, or seven quintillion, five hundred quadrillion grains vs Our own Milky Way is home to around 300 billion stars, seems like a bigger difference to me.

It was a nice way of saying you are way, WAY off
We get the gist of what was being said however.

I used to follow APOD. Kinda forgot about it. Great website.

How did the things involved in the big bang come into existence? (prior to them banging in a big way)

One of the coolest pictures ever taken, Hubble Ultra Deep Field - each point of light on here isn't stars but entire galaxies (and this was purposefully taken from a small point of sky that had very little in it)
To add some perspective for those who don't know, here's the area of the night sky that was photographed to get the HUDF picture with 10,000+ galaxies. About a grain of sand held out at arm's length against the sky.

Actually I believe it won't be too nuts. Because there is so much space in between each star with the galaxies, there's not going to be millions of planets and stars crashing into each other.

I agree with this..I don't think anyone on earth can fathom how big the universe is. Not even the people who study it.
There are an estimated 100 billion stars in our galaxy and something like 10 trillion different galaxies. The scale of that is just massive.
There's definitely other life out there. It seems far more improbable that we would be the only planet to have life forms, than for other planets to have life.

Data shows the speed of light is slowing down
Id love to see the nobel prize winning article on the speed of light slowing down since it is THE universal constant. None of Einstein's Theories would bare the scrutiny they have endured and the discovered proofs of his equations would be possible with a light speed that changed.
Im going to guess your 'data' is from a Christian Creationist Website or the like.

Not slowing, accelerating. There's redshift in all directions.
Sound like we may be approaching a different universe and gravitational pull is involved.

This picture is proof that time travel indeed exists because you're are seeing a photograph of objects from millions and billions of years ago. And considering the first working camera, the camera obscura, was invented around 1,000 AD by Alhazen...that should make this image impossible because this image is of objects millions to billions of years old. The objects in the image predate the first camera which cannot be possible unless time travel is possible.
For example, if an incredibly ancient intelligent alien race created a "HELLO" sign as large as a galaxy and pointed that sign toward Earth, astronomers on Earth would one day see that sign in the deep future.
If images and sound can be broadcast forward into time, or if future civilizations can look backward in time (just look at the night sky), we must assume that it's possible that matter can be projected forward or backward in time too.

Actually, when galaxies collide most often nothing hits each other. There's just so much vast, empty space in galaxies. It's hard to imagine, though.
