There were ideas in the making for a space elevator. A tower some 65,000 feet up anchored down to earth by magnetism. The top would be supported by orbiting satellites. The actual craft that would go up and down this tower would be cargo ships that could be placed in sub orbit then onward to open space. There was even drawing of a modified vehicle (shaped like the space shuttle) that could carry passengers on a sight-seeing excurison to watch the sunset. It would be kept on the tower that was made of some nano metals using huge magnets.

I want to show some kids just how spread out the solar system is. I want to show an orange as the sun, some object of the correct relative size as the earth and tell them how far apart they would be.

Please put the answer in your own words. Please don't come up with some obvious answer like, "It's the lactose. Duh." Please explain in detail what processes in the nervous system cause the feelings of nausea, and how the nervous system is caused to react that way. Please explain which chemical gets assimilated/digested that causes the nausea, and where in the digestive tract it gets digested. Is it the lactose, or some product of the lactose, like for example lactic acid produced by bacterial fermentation? Which bacteria, if any? How does it get digested? What is the connection between the digestive tract and the nervous system? How does the information/matter get transmitted? How do the chemical substances get transmitted?

i'm a 1st year student in college and we've got this biology assignment coming up and we're supposed to present a scientific case study. the main purpose is just so that we get to know and learn the proper scientific methods in doing research. i was hoping to look for weird/funny/really interesting case studies on the internet that i could refer to/elaborate more on during the presentation. i'd really appreciate the help, thanks!!

I know it makes good visual drama, but isn't the "space-dust bathtub effect" incorrect? A star in its lifetime is a sphere. When a star collapses into a black hole, wouldn't it naturally continue to be spherical? In that case, we wouldn't see the "space vortex". Wouldn't we just see a 3D nebula that gets progressively thicker towards its center?
