Dark matter might coexist with normal matter, even dark energy is a mystery. Is the unseen force holding things together, produced by other things which are classified as "dark matter" and "dark energy"? Approx. 90% of the forces that sustain the universe is not produced by ordinary matter & energy. Is the force holding the universe together-brace yourself-spiritual in nature? Will we ever know?

I think its a really good - the theory of panspermia - where comets carry bacteria or cells across the unverse disposing of them on other planets - just like spores or pollen does on this planet. To think we might actually be from another planet! What do others think?

If anyone can help me out with this I would really appreciate it. I can not come up with the right answer that's in the book.

A student siits on a rotating stool holding two 4.0 kg objects. When his arms are extended horizontally, the objects are 1.0 m from the axis of rotation, and he rotates with an angular speed of 0.75 rad/s. The moment of inertia of the student plus stool is 3.0 kg x m2 and is assumed to be constant. The student then pulls the objects horizontally to 0.30 m from the rotation axis.

1. Find the new angular speed of the student. ____ rad/s

2. Find the kinetic energy of the student before and after the objects are pulled in. ____ J before and ____ J after

The standard definition is a body part that was once useful in a species' ancestral past but has now become virtually useless. Those being, the appendix, the tonsils and the tailbone as far as the body structure is concerned. Evolutionists have used the vestigian-organ argument for decades to show the supposed evolution of animal and human bodies. I hink Darwin had written some work on this subject. What is your opinion on this subject? There were 100 useless organs in the early 20th century & now "0" in 2006. What other organs could there be that was considered useless to us?
