Space is big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space. – Douglas Adams

I found a neat link with a logarithmic map of the Universe. This is what the Universe looks like, from our best observing and probing, and from our perspective. Note the following:

1. The speed of light (186,000 miles per second) is a limit on how fast anything can travel.
2. A light year is a unit of distance. It is how far light travels in a year, about 10 trillion kilometers.
3. This means that when we see something a thousand, million or billion light years away that is what it looked like that long ago, when the light first started travelling towards us.
4. The farther away we look in space, the farther back in time we are seeing.
5. Since then, the object has been moving through space and is now somewhere else.
6. So, it is important to realize any map we create is unique based on our perspective in space!
