All stars have spin! |
All stars have spin, including the galaxy itself. In the microscopic
world this isn't so.
If the earth would stop spinning around the sun, would there be weight?

Yes, the spin does not affect gravity.
Of course, in 6 months or so, the earth will hit the sun.

What is the cause of spin (in the macroscopic dimensions)? I mean do we
know what generates it?

Random motion
Conservation of Angular Momentum

especially in collapsing system (galactic and stellar clouds).

All celestial objects are spinors but there must be some force which
generates angular momentum.

You use the word "spinors" not like the rest of us.
Angular momentum can exist independent of force.

Plenty of energy is needed to keep stars in orbit. Force is only needed
to change their momentum.

"S: (n) momentum (the product of a body's mass and its velocity)
'the momentum of the particles was deduced from meteoritic
velocities'"
http://wordnet.princeton.edu/perl/webwn
also:
"S: (n) force ((physics) the influence that produces a change
in a physical quantity) 'force equals mass times acceleration'"
"S: (n) energy ((physics) the capacity of a physical system to
do work; the units of energy are joules or ergs) 'energy can
take a wide variety of forms'"
"S: (n) work ((physics) a manifestation of energy; the transfer
of energy from one physical system to another expressed as the
product of a force and the distance through which it moves a
body in the direction of that force) 'work equals force times
distance'"

Weight

Spinning earth is not a requirement.
