Hi All,
Doug was first with the correct answer: 1/sqrt(2) * speed of light
or a little more than 70% of the speed of light. I figured it
might come down to a race between Doug and Sterling. ;-)
Here's an alternative way of looking at the problem which will
give you the correct answer almost

Reminds me of a question I was asked a while back - what's the
average
time dilation of all mass/particles in the universe, due to the
expansion rate of the universe - i.e how much younger is the universe
now than

Not to be petty, but I beat Doug by at least half an hour.

Ok, so what's the speed of dark?
Let's say you're in a car traveling at the speed of light, does anything
happen if you turn on the headlights?
A conclusion is the place where you got tired of thinking,

Let's round up the acceleration from .7xg to 1g-- just to provide Earthlike

The speed of dark is known to be greater than that of light. It must be,
otherwise the dark wouldnt be able to get out of the lights way.

One more post on this-- I remembered that way back at the dawn of time (okay,
the dawn of the 1990s) in my college English 101 class, I did a paper on fast
interstellar travel. I haven't looked at it in years, as I avoid looking at
most of my early writings for the fear of it being cringe-worthy
Hi Eric and List,
Light itself travels 186,000 miles per second. Do most people
really understand how fast that truly is? Do people realize
how long it would take to travel ANYWHERE in our universe?
At the speed of light, you can actually travel anywhere in the
universe *instantaneously* --

Well, I don't know about *my* reckoning, but for my dogs it would be
either 0.624 or 29.89 years. I'm not sure if I'm supposed to multiply
or divide by seven;-)
My best guess is that it would be a fraction of instantaneous.
