Boltzmann Brains--I'd Rather See Than Be One

Understand

A perceived problem with the standard flat-lambda model is that in the far future spacetime becomes an exponentially expanding de Sitter space, filled with Gibbons-Hawking thermal radiation, and given infinite time there will appear an infinite number of Boltzmann Brains (BB's) per finite co-moving volume today.

• If BB's outnumber ordinary observers by an infinite factor, why am I not one? This Gibbons-Hawking thermal radiation is observer dependent--due to observer dependent event horizons.
• Different observers moving relative to each other will see different photons, and different BB's.
• I will argue that the only particles that are real are the particles dredged out of the quantum vacuum state by particular real material detectors.
