Back in May I posted a request for 'giveaway' meteorites for a series of
presentations I was giving to school students. I realised last night that in the
rush to finish for the summer, writing about it for Meteorite magazine and the
birth of our second child I never publicly thanked those that
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 it 'should be' if it was static?
(I had to think about that one!)
I guess
Since our inertial frame is HERE,
the universe is expanding away from
us and WE are standing still, just like
in good ol' medieval cosmology. We are,
by our own definition, a rest frame.
Therefore, no motion = no dialation of
time.
Around these parts, one second is
one second long, bub!
Now, if
Reminds me of a thought-experiment that I thought of...
If there are an infinite number of Earths stacked on top of each
other, how much gravity do you feel standing on top?

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

The speed of dark is known to be greater than that of light. It must be,

Well, that energy is on the same order at the mass-energy equivalence, so it
doesn't seem unreasonable. You just need an efficient fusion generator. A
matter-antimatter annihilator seems like another possibility. And what's
