In a recent Comment [1], Bizoń and Rostworowski present a few criticisms of our recent Letter [2]. In particular, they present three arguments: (1) that their own evolutions of the two-mode initial data we had studied collapse to a black hole around a time t ≈ 1080 whereas we found no collapse for times up to roughly t = 1500, (2) that our two-timescale framework (TTF) "cannot be even used to infer stability," and (3) that our "claims about stability islands" may not be correct.We have studied evolutions of this initial data with resolutions higher than we had originally. As displayed in Fig. 1, we do find that higher resolutions display higher concentrations of energy, but we nevertheless have still not observed collapse to a black hole. We note that our code demonstrates convergence to a unique solution even at the late times in question (i.e., around t ≈ 1080). We also emphasize that we have demonstrated that the solution to which our numerical results converge is in fact a solution of the scalar anti-de Sitter (AdS) system we seek to solve. This latter property (consistency) is demonstrated with tests that the constraint residuals and mass loss converge to zero (see our Supplementary Material). And so, while it is possible that the continuum solution does in fact collapse around t ≈ 1080 (and indeed, the work of [3] does see collapse in a code for which both convergence and consistency are verified), we cannot confirm this (in time for the publication of [1]) and hence their claim (1).However even if collapse does take place at a time t ≈ 1080, the main claims of our paper still stand. We could not know if collapse occurred after the time which we ran our code, and so collapse for some time soon after t = 1500 was always a possibility. And so if instead collapse occurs at t ≈ 1080, there is no change to our claims. Within that time one still finds both direct and inverse cascades which is now confirmed by the Comment.Another important point is that, were we to decrease the initial amplitude , we would certainly observe any possible collapse pushed to times later than t ≈ 1080.Regarding their claims (2) and (3), there seems to be some misunderstanding of what we tried to communicate in our Letter. Determining whether some scalar perturbation of AdS with arbitrarily small amplitude collapses to a black hole is not possible with numerical evolutions which require some finite , finite resolution, and finite evolution time t.More particularly regarding their claim (2), we agree that the TTF cannot be used to infer stability beyond times ∝ −2 . Indeed, we stressed that we have carried our TTF analysis to O( 3 ) so that one can only trust predictions within times scaling as −2 . However, for shorter times, we disagree with the claims of the Comment that our truncation to j max = 47 "does not suffice to capture the dynamics of the turbulent cascade" for 2-mode initial data. As is clear from Fig. 4 of [2], the vast majority of the energy remains in the lowest modes of the system during evolution, and the dynamics of ...
