How far away in light years does a mirror in space need to be in order to see dinosaurs that existed say 100 million years ago?A mirror in a vacuum 1ly away will return the photonic signal from t=0 at t=2 light years, with diffraction (due to matter in [solid, liquid, gas, plasma, and superfluid/superconductor] phases describable with superfluid quantum gravity (e.g. Fedi's with Bernoulli pressure))

A water droplet [
in space] reflects enough [photonic,] information to recover a modulated signal and also a curvilinear transformation of Escher looking into a crystal ball, with c the speed of light as a consideration only at cosmological distances.
How large of water droplet, a regular or irregular spheroid or reflective and/or lensing matter configuration is necessary to reflect a sufficient amount of photonic information to recover information from cosmological information medium, in terms of constructor theory?

Quantum inverse scattering method > Procedure: https://en.wikipedia.org/wiki/Quantum_inverse_scattering_met... :
> 1. Take an R-matrix which solves the Yang–Baxter equation.
> 2. Take a representation of an algebra T_R satisfying the RTT relations. [[clarification needed]]
> 3. Find the spectrum of the generating function t(u) of the centre of T_R
> 4. Find correlators
