I can't wrack my brain around it no matter how many shows I've watched on it. How did all the gasses get there in the first place? Did they appear out of nowhere? A lot of these astrophysicists say the universe will run out of fuel and eventually come to an end, but there is always the question of dark matter. I don't believe in god at all but it's an easy way out to answer a question.
What happened if the universe didn't exist? People say there would be nothing but what is nothing? It can't have any colour or space as that would be something. It boggles the mind.
The only amusing thing of it all is that our small galaxy is a 100 million light years across amongst billions of other galaxies but people think we are the only lifeform in the universe!
agreed the size of the universe is mind boggling
this is a good example of the beginning of the size

If you're struggling to come to grips with the vastness of space, maybe this video will help. In the video, we see how the sun would shrink if we were traveling away from it at the speed of light. Occasionally, at appropriate intervals, a planet shoots past.
Riding Light from Alphonse Swinehart on Vimeo.
The video lasts 45 minutes, at which point we are less than two minutes past Jupiter. Saturn is still half an hour ahead. The author, Alphonse Swinehart, didn't continue the project out to Pluto, not just because it's not a planet anymore, but because it really would take most of the day. Extend the project to the stars and we would be here for years, and through most of that time, the sun would be a barely detectable dot in the middle of the screen, with nothing else to see.
"I've taken liberties with certain things like the alignment of planets and asteroids, but overall I've kept the size and distances of all the objects as accurate as possible," Swinehart says.
The idea of seeing the universe as one would when riding a light beam isn't new. This isn't a realistic interpretation of something that could really be experienced given the right equipment, however. At the speed of light, time stops, and if one was traveling away from the sun at even close to light-speed, time would slow down and the sun would be drastically red-shifted so that we could barely see it.
However, if you want to get your head around how “really, really BIG” space is, watching the video in full could be a great way to get started
