Which was Von Neumann's point. Once a civilization starts expanding, its ability to expand also expands. The result is an exponential ability to consume local resources, which is more than enough to fuel an indefinite spread through the galaxy at rates which are only limited by Einstein's theories. The result at 1% of the speed of light is 10 million years to cover the galaxy - which is an eyeblink in geological time. Even at 0.1% of the speed of light we could easily reach and colonize the entire Local Cluster (that includes the Andromeda galaxy) before the Sun burns out. It take a truly astronomical coincidence (no pun intended) to find another advanced technological society in our galaxy that has not yet arrived at Earth.

Since exponential growth is faster than cubic, in the limit we can theoretically completely use the resources of an expanding volume of space.

Not if you believe Von Neumann - (ben_tilly) - Sept. 13, 2004, 11:32:41 AM EDT

So what's your answer? -NT - (inthane-chan) - (1) - Sept. 13, 2004, 04:57:57 PM EDT

Don't think it's a valid question at this point - (deSitter) - Sept. 13, 2004, 05:04:22 PM EDT

The speed of light is too low. - (static) - (24) - Sept. 14, 2004, 12:29:44 AM EDT

It is clear the speed of light must be exceeded. - (Andrew Grygus) - (20) - Sept. 14, 2004, 12:35:34 AM EDT

I don't think we'll ever exceed C myself. - (inthane-chan) - (5) - Sept. 14, 2004, 11:21:51 AM EDT

Today’s program has been sponsored by the physical act of gulping. For thousands of years, gulping has been there for human beings when they needed an expressive gesture of the throat. Whether you want to indicate nervousness about an upcoming test or appointment, fear of the Faceless Old Woman Who Secretly Lives in Your Home, or you just want to ingest milk faster than with regular swallowing, gulping is the way to go! Forget sweating, never mind shivering! Sneezing? Ugh! When you think physical actions, think gulping! Gulp now and receive a complimentary prize package, which will be conveniently buried in an unmarked spot somewhere in the Scrublands. Find it, and it’s yours!
