Spectacular. You appear to understand how a portal affects forward momentum, or to be more precise, how it does not. Momentum, a function of mass and velocity, is conserved between portals. In layman's terms, speedy thing goes in, speedy thing comes out.
Unbelievable. You [subject name here] must be the pride of [subject hometown here].
Congratulations. The test is now over. All Aperture technologies remain safely operational up to 4000 degrees Kelvin. Rest assured there is absolutely no chance of a dangerous equipment malfunction prior to your victory candescence. Thank you for participating in the Aperture Science computer aided enrichment activity. Goodbye.
You're kidding me. Did you just throw that Aperture Science Thing-We-Don't-Know-What-It-Does into an Aperture Science Emergency Intelligence Incinerator? That has got to be the dumbest woah, woah, woah...Good news. I figured out what that thing you just incinerated did. It was a morality core they installed after I flooded the enrichment center with a deadly neurotoxin, to make me stop flooding the enrichment center with a deadly neurotoxin, so get comfortable while I warm up the neurotoxin emitters.
I'd just like to point out you were given every opportunity to succeed. There was even going to be a party for you. A big party, that all your friends were invited to. I invited your best friend, the Companion Cube. Of course, he couldn't come because you murdered him. All your other friends couldn't come because you don't have any other friends. Because of how unlikeable you are. It says so here in your personnel file: Unlikeable. Liked by no one. A bitter, unlikeable loner whose passing shall not be mourned. 'Shall not be mourned.' That's exactly what it says. Very formal, very official. It also says you were adopted. So that's funny, too.
Speaking of curiosity, you're curious about what happens after you die, right? Guess what? I know! You're going to find out first-hand before I can finish telling you, though, so I won't bother. I'll give you a hint: you're going to want to pack as much living as you possibly can into the next couple of minutes
I have your brain scanned and permanently backed up in case something terrible happens to you... which it's just about to. Don't believe me? Here. I'll put you on. Hello! That's you! That's how dumb you sound! You've been wrong about every single thing you've ever done, including this thing. You're not smart. You're not a scientist. You're not a doctor. You're not even a full-time employee. Where did your life go so wrong?
