:19:02
We build a cannon, and at the end
:19:04
weld a stopper
made from a subcritical mass.
:19:08
We fabricate a shell
made from another subcritical mass
:19:12
and fire it down the barrel.
:19:15
- How much of both materials?
- Projecting 30 pounds.
:19:18
30 pounds is as far away
as the moon.
:19:21
We're trying to tap the energy
that fuels the universe.
:19:24
It's petrifying. All we've got
so far are problems,
:19:27
and that doesn't include the ones
we haven't thought about.
:19:30
Shake down the bad news.
I'm getting used to it.
:19:33
At the moment, there are
two problems. Pre-detonation.
:19:36
The gadget disintegrates
before it explodes.
:19:39
Second, it's the weight problem.
:19:41
For the slug to travel at the velocity
we need,
:19:44
the gun barrel
would be so heavy, so thick,
:19:46
I don't think we'd get the gadget
off the ground with a crane.
:19:50
If they're talking about a slug
with a seven-inch diameter,
:19:54
then you'd have to have a barrel
thickness of at least four inches.
:20:04
I hope you guys find the music.
:20:06
The way things are,
we can't even hum the tune.
:20:08
Free discussion.
Two groups...
:20:10
- I'm not comfortable with...
- Excuse me.
:20:12
Seth, Deke, the gun barrel.
Robert, Michael, pre-detonation.
:20:19
Damn it! Just, damn it!
Maybe it's the altitude.
:20:24
But we're still just chalk
on a blackboard.
:20:26
We're dead in the water.
:20:28
Maybe we cast a lighter
gun barrel, find a new alloy.
:20:32
The force would be too great.
:20:33
We gotta smack these atoms together
to trigger a chain reaction.
:20:38
We gotta concentrate the energy
and crush the mass.
:20:42
All right, let's rethink this.
:20:44
We have a gun barrel that's so heavy
we can't lift it with a plane.
:20:48
To get the explosive power we need,
it's gotta be heavy.
:20:51
Michael, come here!
:20:54
When I squeeze this...
:20:57
- ...what do I get?
- Juice.
:20:59
No. I squeeze it, I get compression.
