How do you make a time machine? Of course, you would need a power source. Scientists are researching the idea of a device that could harness the power of a black hole. But then what? How do you direct it? How precise would you have to be? What could you use to make sure you ended up where you wanted? I would appreicate all input, and if you come up with a name for some part of a time machine, for example, a 'trans-dimensional locator', write it in. Thanks.
