I've heard that the gallbladder can be removed and, while some people can't eat foods high in fat afterwards without pain and/or vomiting, sometimes it doesn't effect the level of fat intake of a person. But how could a person eat any fat at all if the gallbladder is removed? Does the surgery involve rerouting bile from the liver or is there another substance that breaks down fatty substances?

You know how in some work of fiction, especially in fantasy and science fiction, we see worlds that have more then one moon?
Well, scientifically speaking, what would the effects of multiple moons be on a planet?
Would the tides just rise higher, or whatever? Would night just be brighter? Or would there be other effects?

But during beta decay, a neutron decays into a proton, electron and antineutrino.
So this cluster of quarks is transformed into these new particles? A proton itself is made up of 2 up quarks and 1 down quark I thought, so how this decay phenomena is possible is not clear to me.
What is going on here?
