Based on everything USklav detailed here: User blog:USklaverei/Bleach: The Valley of Screams, Blanks and Senna. I want to recalc Senna pushing away the planets based on the following information:
- https://vsbattles.com/threads/problems-with-the-senna-calculation-bleach.53844/post-1850031
- We are told that the planets have stopped colliding within those 4ish seconds. Which means Senna was able to at least overcome to gravitational potential energy holding the two planets together at said distance (2043.81 km) in that instance. As she would logically have to halt the planets' motions and then drive them away, so prior to moving them away she has to overcome the gravitational potential energy between them.
- |U| = GMm/r, where M = m = 5.972e24 kg in this case, r = 14785810 m as that was the closest we see the planets prior to Senna pushing them away, G = 6.67408e-11 Nm^2/kg^2. Knowing all this we can find the minimum energy Senna with the Blanks overcame to push the planets away to be 1.609e32 joules.
