There's a video on the Internet called Powers of Ten which puts into clear visualation the reality of differences between every power of ten. It starts off with a picture of a person lying on a park lawn in central city, zooming out each time by a factor of ten. At one extreme it ends showing an image taken from the Hubble deep field imager nothing but specs of light which are galaxies, not stars, but galaxies!! They are so far out that only the accumulated light emmitted is from an object large enough to be a galaxy!!! Then the camera zooms back in and eventually shows scenes of negative powers of ten down to inner space around individual electrons. It's a way cool video. When we look at the Nasa photo depicting nothing but galaxies as points of light, we are looking way, way back into the very early times of the universe. And that photograph is dotted with loads of galaxies!audioguru said:Hi Crummy Link,
That Soviet bomb makes a pretty big BANG.
My head is still swimming about orders of magnitude after I saw a pic taken by the Hubble Space Telescope.
The light travelled for 28 million years to reach the telescope.
The gallaxy has 800 billion suns. (800,000,000,000)
It takes light 50,000 years for light to go from one side of that gallaxy to the other.
And there are billions of other gallaxies!
I've often wondered about this (yeah, I'm a loner). Is a vacuum determined merely by density, and not proximity? What is the unit of measurement for the power of nothing? How hard does nothing suck?HiTech said:Eventually you would pop.
