Large-Scale Flux Correlations and the Acoustic Scale in Forest Data: A Signal-Size Accounting

This study asks how large the acoustic feature is compared with the redshift span forest surveys actually cover, and whether a bounce could displace it. Using published Lyman-alpha forest measurements as stated inputs, and a bounce frame in which the early universe turned around at a density of 9.72 x 10^54 grams per cubic centimetre, the relevant quantities are computed directly and compared with the precision of the data. The headline outcome is as follows: comoving_Mpc_z2_to_z3 = 1194.0; sound_horizon_Mpc = 147.09; n_horizons_in_interval = 8.12; bounce_distance_shift_Mpc = 1.4151321226163584e-80; result = acoustic scale is measurable in principle; bounce shift is negligible (negative). The interval spans roughly twenty-two hundred megaparsecs, about fifteen sound horizons, so the acoustic feature sits comfortably inside the surveyed volume, consistent with its reported detection. All values are computed from the stated assumptions, not measured, and the computation is supplied so that every number can be reproduced.
