<p>This is unfortunately as impractical as Alcubierre's solution,
and it is surprising it is getting airtime. It doesn't give us
FTL, for one, whereas AFAIK this was already solved, even in our
Universe?<br>
</p>

</p>
<p>Erik Lentz[0] seems to have most of the practicalities figured
out, and is merely fighting with orders of magnitude--something we
should be used to conquering here.</p>

<p class="MsoNormal">A Groundbreaking Scientific Discovery
Just Gave Humanity the Keys to<br>
Interstellar Travel.<br>
In a first, this warp drive actually obeys the laws of
physics.<br>

<br>
The Alcubierre drive has a glaring problem: the force
behind its<br>
operation, called “negative energy,” involves exotic<br>
particles—hypothetical matter that, as far as we know,
doesn’t exist<br>
in our universe. And faster-than-light travel is
impossible.<br>
<br>
But a new proposal allows for up-to-light-speed warp
drive. So, still<br>
impossible at present, but researchers are hopeful. :)<br>
<br>
Interesting article!<br>
