Ask HN: I think I improved an Erdős problem how can I verify it?

For this model I kinda just made up my own system to play around with it, while it wasn't very effective it was pretty fun. That being said thanks a lot for the recommendations, I wasn't very aware of the options I had for it.

I completely agree with what your saying, with one caveat. If I understand how the underlying physics and dynamics are working but don't know how to write the code then theres no world where I could make something like this. The way th

Around 90% AI for syntax, I did alot of debugging manually. For implementing new features I would design them and do the reasearch then have a AI write lines for me and verify the work

Its fairly accurate as far as I can tell. Your right about the fact that It wouldnt work in real life due to the dynamic pressure your exerting on your rocket, using your method you get to about 150 kPa, Falcon 9 usually maxes out around 35

Took the anti grav sleds off, might be possible to crash into now idk

I found the problem, It appears that I had the earth staying stationary but gave its rotational velocity to the rocket, What i think needs to happen is I need to also be rotating the earth so the inertial frame stays the same. Thanks for br

Good point, I implemented that very early and hadn't really thought about it, let me look into the true solution, thanks

yup, derived most of the equations myself then double checked them before implementing them. That being said all of the positining is done through time steps and not so much equations

Awesome, thanks alot, thats a great idea to work on

Thats due to the rotation of the earth, for the purposes of the simulation the earth is rotating at 408 m/s (earths rotation at cape canaveral) so thats why It appears its going sideways
