without gravity, crap would stick to you when you were on the toilet.


I know that crap moves along the small intestine by peristaltic action but would it leave the rectum without gravity?

Jupiter does cause the Sun to wobble. The Doppler effect is used to detect other wobbling stars. The wobble would cause these stars to move towards us (compresses electromagnetic waves) and then away from us (extends them). If a star is detected to have this wobble then there must be a gas giant in it's system to cause it.
