Tachyon Particles

    What is a Tachyon particle? Well, for those of you who are not familiar with theoretical physics, or have never watched Star Trek (Not that I really blame you...) a Tachyon particle is well, a particle. It is special because it travels at very high speeds. So high in fact, that they travel backwards in time! Of course, the major problem is that they do not, technically, exist. Not in reality anyway, they are purely theoretical at this point.
    As Emperor, one of my first priorities would be to accelerate research of such things. Under a unified world order, weapons of mass destruction would not be needed, only smaller weapons for the subjugation of revolting areas. So this time and effort could be directed towards research in the areas of Tachyon particles, and of course, hamsters.
    You wonder what the practical applications of this are? They are numerous, and could prove very useful in the Crusade Against Stupidity.

Tachyon Internet

Imagine, you send an email, and it arrives before you sent it! The recipient could reply to it before the original was even sent! Talk about advance knowledge...

Tachyon Weaponry

Imagine a Tachyon rifle, I fire, and you're dead before I pull the trigger. Now apply this to ICBMs. Fun isn't it?

Pet Food

You feed your pet gerbil Tachyon Pet Food, and it digests it and poops it out before it's fed! This makes clean up a breeze, and imagine the look on it's face!

Cars

Reverse time-travel. Enough said.

Medication

You're cured before you even got the disease!

Watches

Know what time it was an hour ago! Wait...

Entertainment

Finish a book you've never had time to read, watch a TV program that was on an hour ago, there are infinite possibilities!

Of course, this may fracture the time-space continuum and possibly destroy the universe, but hey, everything has risks.

As followers of the Crusade all of you would have access to some Tachyon technology, provided it is developed, and you can use it to demonstrate your power to the ignorant masses. If you haven't enlisted in the Imperial govenment, forget it Ignorant One, you'll never get access. How will we protect it you say? Easy: Tachyon Alarms, they'll ring before you even break in!
