Space Is Big
« on: January 24, 2013, 11:33:45 AM »
"Space is big. Really big. You just won't believe how vastly hugely mind-bogglingly big it is."  - Douglas Adams

This video over on the Astronomy Picture Of the Day site shows what it would be like to fly among the galaxies. Not stars. Galaxies.

The real question about our universe is what is it?

even this vid does not show how big space really is.....

the Andromeda Galaxy the closest galaxy to earth, is about 2.5 million light years away from us.....

speed of light is 186,000 miles a second....

so traveling at 186,000 miles a second for 2.5 million years.......

will only get us to the closest neighboring Galaxy........ :O



a little tidbit.....( ya I used to love reading about the universes)

there is a star that is so dense....a square centimeter of its material would weight 300 lbs on earth...... :O

Makes me sad that people fight wars with the knowledge that they are dust particles.

  the game is concentrated on combat, not on shaking the screen.

This always blew my mind.....There are more galaxys in the universe, than grains of sand on the Earth.

or

A teaspoon of a Neutron Star would weigh as much as a mountain

Character is like a tree and reputation like its shadow. The shadow is what we think of it; the tree is the real thing.

When the game is over, the Kings and Pawns all go into the same box.

But it is getting closer all the time and will collide with the Milky Way someday in the far future.

People have to be mind boggling stupid to look at all that and still think we're the only intelligent life form out there.

we will be walking on the sun when that happens, and be able to travel at the speed of thought. :aok

Rest assured, there are different types bacteria fighting over some unknown location on your body too. That should put things in perspective. :cool:
