Scale of the Universe

Can someone explain to me if the Universe is supposed to be 14,000,000,000 years old, how can it be estimated to be 93,000,000,000 light years wide?<p>Assuming the Big Bang, doesn't that imply the 'outer matter' must have an average velocity of about 3.3 times the speed of light?

it's still nice but it's been here before: <a href="http://news.ycombinator.com/item?id=1835460" rel="nofollow">http://news.ycombinator.com/item?id=1835460</a><p>BTW: since there's no search feature to check for older posts, I suggest you use google: site:ycombinator.com

And I was getting big-headed this morning for solving a silly problem for a client. Thanks for reminding me of my place. :)

If there is a minimum physical length, that is a planck length, does that mean that nothing is technically continuous? Or, is it possible to imagine 'half a planck length'?

Try doing a fast zoom out from the smallest to the largest. If you do it at just the right speed, it will give you serious goosebumps.

Always been amazed at how really small things (atoms) look a lot like really big things (solar systems) (ya, ya, same forces...)

I would point out that the ant is precisely in the middle of the scale between small and large. Think about that, grasshopper.

Aw, they changed the theme tune.

How not to feel sooooo small and insignificant after that !?

That... is spectacular...
