Thank you!
I realized after I sent the last post that I goofed on the density part.
Apreciate you all hanging in there and getting through to me.

Thanks, I'm beginning to get the picture maybe??
Let me get this on the table to help me understand.
If a cubic centimeter of say iron weighs about 8 grams at... (view)

I appreciate the responses. Still scrachting!
Isn't gravity and weight related, and if there is diminishing gravity as we get closer to the center of the Earth.... (view)

Yes, I wouldn't expect the matter there to sublimate but be attracted with the force of gravity outwards from the center. Maybe the center is of very low density.... (view)

The speed of light was measured by rotating mirrors, and was done in 1849 by Armand Fizeau. Look up Fizeau wheel for details. (view)
