The Universe or rather a small part of it..
Yesterday, I had the oppurtunity to revisit the thought.... the enormity of this Universe. I had my fundas confused. I had to refresh them... Just putting them so that I would not forget them again.
1. Our earth has thin crust of a maximuim of 40miles deep. All your Everests(8.8Km == 6miles) and Marina Trenches are on this.

2. Our Mother earth is a part of the Solar System with the Sun as the center.

3. Our Solar system is a small spec in the Galaxy call the Milky Way.

4. The Milky Way belongs to a Cluster of Galaxies called the Local Cluster.
5. Local Cluster is a part of the "Greater Local Cluster"
6. And then there are Billions of Galaxies and Galatical Clusters.

7. And most probably there are more that we dont know of yet.....
8. Also all this matter is not just tightly packed into one box. There are huge amount of open spaces between each Galaxy. I will find out about the density as post it here. The other thing I leart is that the nearest cousin to our Milky way - the Andromeda is on a collision course with Milky way and is travelling at 186miles/sec (gulp..) towards us. But it would take about 200 billion years to here (hee hee). But the unfortunate thing is that we(homo sapiens) would'nt have left the planet to live for so long. Our Milky Way itself is travelling towards the center of the Local Cluster at 168miles/sec. Well gavity is working ! Always!
9. Our 9minutes of fame and 1 sec of madness! on a Time Scale of the Universe
