Dropping charges onto a superthin surface (and keeping it cold, we have to consider arbitrarily large SMBHs too) or having the superthin surface emit Hawking radiation is hard to make not-a-toy (step 0: spectral structure evolution; step 1: ultraboost something, Aichelburg-Sexl style pancake; step 2: astronomer near ISCO around a distant SMBH; step 3: Rindler particles from the membrane&#x27;s pole; step 4: incoming ultra-high-energy cosmic rays, GZK-like cutoff…</p><p><a href="https://hackerpaper.kaipfister.de/p/gr-qc_0605131/">Paper and discussion history</a>.
