Quantum jitters become thermal fluctuations near the horizon as explained on page 359. These fluctuations are responsible for Bob's observation of the smashing of the atom falling together with Alice. But what happens to Alice from Bob's perspective? She is also made of atoms and therefore, every atom in her body will be also smashed from Bob's perspective. That means she will be already dead before reaching the horizon. But from Alice's perspective, nothing extraordinary happened as she crosses the horizon. She will die later when the tidal forces near the singularity become too strong (I'm assuming a huge black hole, where tidal forces are unbearable only very near the singularity).
How to explain this apparent paradox of Alice being dead and alive depending on two different perspectives?
