Hi All,
A friend pointed out to me that if you wrote 2 +2 = on the Google cross
bar
it would return 4. I purchased
The Ultimate Google Resource
by Michael Miller
A QUE publication (Second Edition)
Knowing (assuming) this could be extended. In chapter 15 I found that if
I
entered
m_moon*c*c
it would return, below the search bar (as well as doing the search)
"mass of the Moon * the speed of light * the speed of light = 6.61483812 ×
1039 joules
More about calculator."
Now this may or not be correct because of units. But just enter each
quantity on the line and Google will supply the quantity's name, its
value,
and the units of that value. Google supplies Planck's constant, h, Atomic
mass units, amu, etc., etc. [Something to know ... although I may be the
last to have found out.]
Now, the reason for this post.
MOONS DON'T SEEM TO HAVE MOONS?? Now the Earth revolves around the Sun,
and
the moon about the Earth; So what is the criteria (mass and velocity) for
the moon to have a moon? --- or is the situation such that the mass of
earth
(m-earth), and distance to the moon preclude the possibility?

I'd be interested in any criteria you WORK OUT, BUT NOT YOU BLUE SKY
OPINION. By the way, am I correct that none of the moons in out solar
system have moons?
Best wishes, Jim
