For someone who have just finished the study of the (fundamentals) of Schwarzschild spacetime, what would be the next natural topic to study?

My main reason for posting this is to prevent overreaction to the research, especially from the "pill press" internet people and the impact that has on non-science people. Yes, it is interesting. No, it is not definitive. Worried about it? Take a short 10 minute walk, 5 or 6 days a week, in...

Using the Lagrangian of the system I reached that ##x(t)=\frac{1}{2} gt^2+ut ## is the real trajectory of the particle. After that, I consider different trajectories: ##x(\alpha,t) = x(t) + \alpha(t)## with ##\alpha(t)## being an arbitrary function of t expect for the conditions...
