The infinite depth bug

[Klapaucius]

I was working on my newest challenge, a continuation of my Mountain Lake Landing challenge, and wanted to just see how deep the lake was. Using mission builder, I put Jeb on an ore tank and placed him at the bottom of the lake. He somehow passed through the bottom of the lake and is currently falling forever in an underwater void. Current depth as of this post: 35,000 metres.

About 9 hours from the moment of your screenshot Jeb should be reaching a depth of 600000 m. It would be interesting to see what happens then.

I was thinking the same thing. I'm just going to let it run and see if the program realizes he is inside the planet or not.  It has gotten a lot darker.

Not just that, but he's actually accelerating as he goes deeper - gravity is increasing. KER is either very confused already, or sub-surface physics follow a different set of rules.

I almost feel the urge to ask Jeb to turn on his helmet lights.

Almost.

Then the thought occured to me that we may not want to know what may be swimming right by him...

I did not notice that!  I just rechecked and he is now over 50! He is also shaking a lot.

Soon now he'll start typing garbled text... then he'll be silent for a while and come back much clearer, but claim that he can see light from below.

[Klapaucius]

It's gotten lighter again.

<nods sadly> He's obviously hallucinating.

Not sure if anybody has ever gone to the center of the planet.   This I'm interested to see.

 

And for some reason, this firefox update has deleted my dictionary, it thinks every word I type is mispelled.

Hours spent trying to build a better, faster submarine, and I set a record for aquatic travel with a command seat bolted to an ore tank!  108m/s at 503,000 metres below sea level.

Mission accomplished, I would say.

I seem to recall seeing another image album from a similar glitch, but with an actual submarine-looking vehicle. As I recall, at a few kilometers from the core, it got ripped apart by the tidal forces.

[Klapaucius]

And now we know....sort of.

Yes, that is what happened.  See the above video. But I got to 1900 mps!

Looks like the lil geek imploded...

I consider that expected.  (Expected in the ksp case, not expected in the real world).  I seriously doubt ksp is modelling a planet with its mass distributed throughout its volume.  It's almost certainly simply modeling the planet's mass as a point source at the planet's centre.  That approximation will work fine for anything on or near the surface, or in space.  However deep underground, acceleration due to gravity will increase, since you are now getting closer to that point mass.

What caught my attention was that it started to rapidly accelerate at the very end, don't really understand why
However, is there a possibility that it exploded due to overheating rather than invisible wall/ripped apart due to G forces? Maybe if you turned some Alt-F12 options on, you could get through

Inverse square relation with distance... it's gravity after all.

If it makes it that far, I'm hoping for a secret subkerbnean world populated by Kerbal Dinosaurs and cavekerbals.

Maybe they'll be chasing Doug Kerman and a team of fellow surface dwellers around.

[Vanamonde]

He'll meet these guys soon. 

[Klapaucius]

Since it was in Mission Builder, I tried swapping out the vehicle with a proper sub, but the craft just formed on the wall of the lake and broke apart.

No.

Just no.

Tell me that's not a real thing that's alive somewhere potentially waiting in the darkness of the abyss to eat my face. Please?

In KSP you have an thin shell who is the surface and an singularity in the center. 
Gravity goes towards infinite as you get closer, g meter was peaked at 15g the all time but real gravity was obviously far higher as in thousands of g, enough to take you past 1.5 km/s underwater, however I assume the same would happen in air just that the drag is lower so you would overheat faster. 

I had this clipping happening on the Mun, no air resistance so it accelerated all the way. Now as you get close to the singularity things get weird. As KSP only calculates every 50 milliseconds, the acceleration and speed increased exponential who closer you get, at the closest point you get an random speed based on your distance to singularity, i only got 1/3 c, however this is so fast that the next calculation put you above the surface and even if not you would be so far from the singularity that gravity would hardly slow you. 

If this happens again turn off heating and you get the singularity encounter in slow motion.

How do you turn off heating?

The debug menu. On Windows: Alt-F12, Cheats, Ignore Max Temperature. Heating still happens, but parts don't go poof anymore when past their temp limit.
