i remember when i took an astromy class but the teacher was so bad 95% of us dropped it etc.
anyway, i love the subject and i remeber we tracked the location of the moon and it didn't actually revolve around earth
it went in an s pattern adjacent to us
so we are in an eclipse shape and it is behind us or in front of us (or beside us) relative to the sun
Is that true??

I remember reading about a theory that said something about earth poles once being at the equator. I think that it said something about shift in the rotation of the Earth as an explanation. Does a theory exist? i tried looking for it on-line but no luck.

Neutron stars can pack more than a sun's worth of material into a city-sized sphere. A few cups of neutron-star stuff would outweigh Mount Everest.

We have only been to mars, a rover on a saturn moon, have sent probes out to charter the universe, Voyager is by the farthest but still no where near a neutron star. How do they know that a few cups of neurton star "STUFF" (which is a great scientific term) would out weigh Mt Everest.
