The study and exploitation of bugs is an important part of the scientific process, and has applications in the real world. For example, black holes are a ball of matter with so much gravity compacted into such a small area that even light isn't fast enough to escape if it gets too close. But there is one small detail that we've found that changes everything. Black holes can spin. They have angular momentum. And that means that we can extract energy from it. All we need is a mirror and some light, and we can siphon energy out via super-radiant scattering (and if we don't siphon energy and just let it build, we'll detonate the biggest explosion humanity could ever achieve). Seems a bit buggy, doesn't it?
@@entropybear5847 I mean, quantum physics and general physics seem to be incredibly contradictory and refuses to unify neatly without also contradicting observable reality (**cough** string theory **cough**).

U should leave this in "orbit" so every now and again the new guy working at the ksp just sees a flash of light and some senior staff member just goes "oh there's Gary and the boys flying by again"
You can't. As soon as it's out of render distance the orbital mechanics engine says "deorbited due to drag and crashed". The cutoff altitude is something like 30k where it changes to saying "went right through the atmosphere like it wasn't there".
This shows that orbit is all about the speed relative to the planet's surface, not the altitude. We go to such high altitudes because our rockets would melt if we tried this IRL. But on the moon you can orbit easily by going up for a couple of seconds and at any altitude just burn relative to the surface. No atmosphere means no friction! :D great video friend
I'm pretty sure George Kerman would appreciate it if you don't orbit low enough to hit him in the head with a 30-ton rocket going at several kilometers per second, though.
On sfs a 2d kerbal lookalike for mobile i like to set up orbits around moons and asteroids as low as possible to see the relative speed in effect its really cool to orbit the moon at 500m
according to my math (mission timestamp and orbital speed): 1st second 29G, 2nd second 22G, 3rd second 8G, 4th is around 5G then its under 3 going foward from 5th second. for those split time, forces go like these 13 - 10 - 3,5 - 2,5 - 1,1 in kiloN

Imagine being in one of Kerbin's remote towns, you're out there to go for a hot-air balloon ride, you start getting some good height, get a great view, and then in the distance someone notices the darndest thing, almost like a fireball in the distance growing larger.

I can imagine an alien visiting like “welcome to kerbin!” One last thing. If you climb our highest peaks or plan to solo fly be careful. There is a cylinder orbiting our planet at a very low altitude and beware it’s sonic boom as you could probably touch it with your hand it is orbiting that low

Very fun video! You could create dragless wings by attaching heat shields to engine plates. With this you could "orbit" Kerbin much faster by using the wings to force your craft down, even if your craft is at escape velocity.
I did something similar in Spaceflight simulator, I switched to another craft while one of my other crafts was entering the atmosphere, and then timewarped 5x so then physics didn’t apply to the craft in the atmosphere so I basically had an orbit of 30 meters.
I wonder what would happen if you devised an entire fleet of 7K orbit satellites to just watch wiz over the KSC repeatedly. I'd imagine something would go horribly wrong on the craft loading in, that or the low altitude would consider the object out of orbit and delete it on reloads.
done some math based on mission timestamp and orbital speed, frame by frame: 1st second deceleration 29G, 2nd second 22G, 3rd second 8G, 4th is around 5G then its under 3G going foward from 5th second. for those split time, forces go like these 13 - 10 - 3,5 - 2,5 - 1,1 in kiloN assuming a 45kg kerbal (data point for +2s is bit off) so on average i think the 2 seconds peak is survivable if the kerbals are very properly secured and cushioned, like wholly encased and epoxied in some form of high density foam
