No. What might emerge are hydrogen molecules (following quark confinement, free neutron decay, chemistry, etc.). The "information" to "reconstitute" the unfortunate astronaut's body is diffused forever.

Why do people write this stuff?

For that matter, try this wild speculation: Lenny Susskind, "Dear Quibitzers" GR=QM[0], in which he reifys[1] his toy models and carries on as if they were (almost) objective reality.

He's a professor at Stanford. I'm reminded of Pauli's remark, "Your theory is crazy. But is it crazy enough?" It seems that a physicist can say almost anything these days.
