I hadn't had my coffee yet 
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

I have a fridge magnet that reads "DANGER! I haven't had my coffee yet..."
So, what's wrong with it?
It's a delicate pastel green.
It should be dayglo orange, at the very least.
Cheers,

 I had to share that with my wife who's sitting next me working on a watercolor drawing. That was, well, grate!

Old news. As the article says, this method of creating a space warp has been known for about 25 years. The problem is that naive calculations of the amount of energy required to warp space in the desired manner give a value larger than the Sun's total output. 
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Oh crap.
You're not saying Mazda has anything to do with it are you? They couldn't even keep the 26b and 20b motors coming.

Öutput? if it were only that. The energy equivalent of a complete star mass. If we are very lucky 'only' that of the mass of a large planet, wich should still be much more than the sun's output.

So the tl;dr is:
0. nothing in relativity suggests that spacetime cannot contract or stretch faster than light
1. nothing in physics says energy density can’t be negative
So all you have to do is both of those things, and Hey, Presto! FTL travel!
I feel I should point out the slightly bleeding obvious flaw in the reasoning -- the fact that no-one says that something can't happen doesn't mean that it can!
Often, if no-one says something can happen, it's because it can't. In this instance, for example, we use abstract determiners that were invented by people to quantify things (it's quite common to call them "numbers").
When working with numbers, it's really easy to make stupid suppositions, because the real world doesn't force numbers to behave like the non-abstract things that the numbers represent.
E.g. for point 1, solve this:
If you have five pounds of potatoes, and someone steals eight pounds of potatoes from you, how many pounds of potatoes are you left with?
Easy, no?
You've got -3 pounds of potatoes.
Now perform the experiment with real potatoes, rather than abstract quantifiers (those "number" things, again), and send me a photo of what -3 pounds of potatoes looks like.
The only difference between doing this with potatoes and doing it with "energy density" is that if you do it with "energy density", and act all clever and intellectual, some people won't realise that you're a bleeding idiot.

Just because you can't photograph it, does't mean that -3 pounds of potatoes isn't "real" - that's the idea that banking is based on; heck my bank account relied on it for years after I got out of Uni and trust me, I was assured often enough that that was for real!

So if I invite you round for dinner, and I tell you that you'll be having -1 steak, it means that you'll have to bring a steak and give it to me, and then you don't eat?
OK, I can get behind that.

Regrettably, I'm busy that day so I will have to decline your invitation. If you are in the area feel free to drop in for -2 bottles of wine.

0 - spacetime is already expanding faster than the speed of light, we know that!
|
|
|
|
|
So we just need to grab the expansion handles, and let it drag us!
Now that's a good theory!

Is it, really, today?
I know that it was in the old days, back in the inflation period, but I thought it had calmed down since.
(I certainly am not an astrophysicist, so I am asking out of curiosity.)
