Using 2 lobsters and 2 placeholders with impeccable timing theretically allows indefinite ascent:
0.000: Both Lobsters simultaneously launch the whole congregation upwards. This means they both also get launched.
- Lobsters now need 8.5 seconds to reload.
1.500: In about 1.5 seconds, at peak of the launch trajectory, placeholder 1 fires.
- Black hole lasts 13.3 seconds.
- Placeholder now needs 14 seconds to reload
- Lobsters still need 7 seconds to reload.
- The whole assembly hangs in the air, reloading.
8.500: Lobsters reload and fire again, gaining more altitude.
10.000: The climbers are again at peak. Placeholder 2 fires.
- Placeholder 1 still has 5.5 seconds before it can fire again.
- Placeholder 2 now enters 14 second reload.
- Lobsters still need 7 seconds of reloading
17.000: Lobsters are ready to fire again. So is placeholder 1. The cycle is complete.
