Slowing down time is possible. It just takes inordinate amounts of energy to do so. 'bout... 3-4 Suns.

As is moving objects through time. Although it doesn't cost as much, apparently.

(Yeah, I don't know what I'm talking about. I am studying for my physics final, but... >.> ::too easily distracted:: hell, this wasn't even related to harmonic motion.)

Hm! Which time-travel system are you thinking of? ISTR one involving a very long cylinder spinning around its length at near light speed, causing a space-time warp. (A Tardis is much more convenient, I find)

Not too sure, actually. Probably semi-magical, from http://www.youngwizards.com/.

Ahhh. I should have a look. ^_^

Here's the system I was thinking of:

"Get a bunch of neutron stars and fashion them into a cylinder about 100 kilometres long and with a 10 kilometre radius. Then spin the cylinder about 2,000 times per second. The surface should be moving at about half the speed of light by now. According to Tippler's theory, it should be dragging the space-time fabric with it, with enough force to mix up space and time. Now fly your 'spaceship' in a specific orbit around the giant cylinder. This should, in theory, take you back in time, but only till when the machine first started spinning. As you can imagine, this requires some practically impossible engineering, but there are no theoretical reasons why it wouldn't work."
