Loving HOW THE UNIVERSE WORKS episodes on the SMITHOSONIAN CHANNEL, but bewilered by new episode tonight
on DARK MATTER in which astronomers throw up their hands when asked how much of it there is? They don't know.
They don't know how to "measure it". Why wouldn't this work:
+ In a given area of the universe, carve out an imaginary sphere.
+ Calculate the mass of the sphere.
+ Calculate the mass of everything within the sphere.
+ Determine the difference
Shouln't this render a resasonable estiamte on the amount of DARK MATTER (maybe also DARK ENERGY?) in the sphere?
As a cross-check:
+ Now carve out, say, 20 other imaginary spheres in the universe
+ Conduct the same calculations as above
+ If there is consistence in this experiment, then we should be onto something, shouldn't we?
