...Given that Uli-Oa is currently about the size of Earth, that there is an explosion roughly the size of a continent. Roughly. The mathematicians here can argue about exact sizes, me I'm content to say that that would probably be a dinosaur-killer on any normal planet.

Yup. Howard already noted that this was about equal to three point three dinosaur killers, but I certainly would not want to be standing anywhere close to impact.

There goes my thread title; "Point one four cee".

Sorry, but it appears my sonar got the title detected first.

That is a REALLY long projectile. It's longer than Uli-Oa is wide.

That projectile is longer than Saturn.

Believe that's supposed to represent the motion of the object.

How much energy does it take to bring that impactor up to that speed?

Where do you get that much energy?

Given the "energy loss" (ringing, etc), that won't contribute to the strip mining, is it really more efficient than just using an annie plant to make more ptu's?

They actually have something very much like nany black now. They call it Vantablack.

For every 10,000 photons that hit it, 28 will reflect. The photos look creepy. Basically it makes a bunch of carbon nano tubes on the surface, standing up.

Considering the pieces being broken off are the size of *cities*, made of pure PTUs, and a ship the size of the Touch-and-Go could probably ramp that rock up to speed - its going pretty slowly compared to what most would consider a relativistic kill vehicle in the 30th century - i'd say 'it's totally worth it.

Annie plants likely don't make many PTUs very quickly, and much of it goes back into making Annie plants. Energy is *essentially* free - or at least extremely plentiful in the world of Schlock, and you don't have to expend all of the energy getting the rock up to speed all at once. You can take days, or weeks to do it, which takes much less energy, and can be expended steadily.

This is hardly one of Petey's old 'Fastball' ships that needed annie plants the size of entire battleplates to slow them down.

I meant "Point Four One Cee"... I HATE having dyscalculia. Stupid numbers won't quit jumping around...

Others find it really frustrating, too. We can discuss astrophysics, quantum mechanics and everything else.. but my brain just can't grok the math. I get how the stuff interacts, but it would save a lot of unnecessary exposition if they could just relate it in formula, instead of trying desperately not to talk down to me.
