All Askew In the Heavens

It's crazy to think that when Einstein lived newspapers were so primitive. To this day media seems to be in a different age than science.

Tractor

Man, this is incredibly cool.  Imagine we could do something similar with spacetime itself---then we really would have Star Trek-style tractor beams!  Oh, and also this could have real-world applications as is.

If I had time I would like to understand what's different about the physics of water surface waves vs. "body waves" like light waves or sound waves that travel through the whole body rather than just the surface.

Apparently there has been other academic research on tractor-type beams.

more authors?

Do y'all think I should invite some more authors for the blog?  I can think of several people that might have some interesting stuff to add...Please reply in the comments.  We can discuss specific suggestions offline.

If there aren't responses I'm going to assume no one is still reading

simple and cool
