If you were on a globe and had view Horizon Limit of 300,000 kilometers from a height of one meter, What would be the radius of the Globe??

HUGE! something like 4.5e10km unless i dropped a few zeros.

And how far would one meter divided by that number be?

The formula is for the radius in term of distance and height is ( for h
d )

r = d^2 / (2 h)

r = (300 000 km)^2 / (.002 km) = 4.5 x 10^13 km

right, i did drop some zeros. as far as dividing it into 1m, get a
calculator!

Sorry to keep Bugging everybody but,
What would be the diameter of this diagram?

So our universe curves one meter over 300,000,000 meters.
It is almost flat, but not quite

So if the sun were shooting neutrons at the speed of light at the earth we
would only see the ones that decay within our horizon.

510 seconds * sqr pi = 903.95 seconds

if they were at the speed of light we would never see them decay. and the
sun doesn't put out enough energy to get them to that speed anyway.
