Thanks, but after a big bang, to come to a stop?

 

Does that mean earth will also, in time? due to same forces?

 

Maybe the "other side" (which does get light) is concave?

 

"A widely spread misapprehension is that a tidally locked body permanently turns one side to its host (e.g. in Neron de Surgy & Laskar 1997; Joshi et al. 1997; Grießmeier et al. 2004; Khodachenko et al. 2007). Various other studies only include the impact of eccentricity on tidal locking, neglecting the contribution from obliquity (Goldreich& Soter 1966; Goldreich 1966; Eggleton et al. 1998; Trilling 2000; Showman & Guillot 2002; Dobbs-Dixon et al. 2004; Selsis et al. 2007; Barnes et al. 2008). As long as ‘tidal locking’ denotes only the state of dωp/dt = 0, the actual equilibrium rotation period, as predicted by the CTL model of Lec10, may differ from the orbital period, namely when e ≠ 0 and/or ψp ≠ 0. Only if ‘tidal locking’ depicts the recession of tidal processes in general, when e = 0 and ψp = 0 in Lec10’s model, then ωp = n. As given by Eq. (23), one side of the planet is permanently orientated towards the star if both e = 0 and ψ = 0 [2]. In this case, habitability of a planet can potentially be ruled out when the planet’s atmosphere freezes out on the dark side and/or evaporates on the bright side (Joshi et al. 1997). As long as e and ψp are not eroded, however, the planet can be prevented from an ωp = n locking. In the CPL model, however, the equilibrium rotation state is not a function of ψp, thus ‘tidal locking’, denoting dωp/dt = 0, indeed can occur for ψp ≠ 0."
