The size of earth compared to other objects in space.

They have different aims. Celestia is a 3d space simulation, and Stellarium is more like a 'night sky' simulation. I use both.

IT would be nice to have a integration of google earth, stellarium, celestia all together..

Grasping the idea of the size of the earth within the visible universe is so difficult as it is sometimes difficult just to grasp the shear size of earth compared to the size of a soccer ball for example.

The universe's growth is disturbing. Because, there's a theory that states that the universe may become so massive that the expansion of space reverses, and time flows backwards until the universe recollapses, ultimately ending as a black hole. But, it's highly unlikely. It's called the big crunch.

To the above, and others who have touched on the subject of what's at the centre of the universe: Mrs Lisati, our neighbour and myself share the responsibility of being the centre of the universe, and occasionally take on the responsibility of being the universe.

(/me wanders off in search of medication bag to see if there's something there that will help ease the pressure. Great disappointment to discover that there's only pills to help with a heart condition and diabetes-related issues. Not even a little blue pill. Sigh. Dreams are free!)
