 I believe in one-way time machines: Just hustle.
I believe in synthesizing gold: Get a neutron generator and
neutron-activate
a few kg, er ... a few nuclei of Hg.  Mostly, though, you'll just change
the
isotopic ratios of Hg.

The time machine is something very amusing, but it is science fiction.
It is above all another abstract theory.
Those who think, and there are many of them, that we can go back in time, or that we can find tachyons are deluding themselves. They show by this that they do not have complete knowledge of the theory of relativity.
To think that we can find tachyons, or that we can go back in time, is just as absurd as looking for rabbit horns and blue unicorns.
Let's take the example of a perfectly stupid university professor, who will set his mind on finding two natural squares, one of which would be double the other, or one of which would be triple the other.
Simple mathematical reasoning proves that this is impossible, with the most perfect certainty.
The same goes for time machines, it's impossible, abstract, it doesn't exist in our universe, and what's more, the notions of breaking causality would be so terrifying and so grotesque, that we quickly lose the simple desire to think about it.
