"Transcended doubling might
run up against the laws of physics before reaching infinity... but
even the laws of physics as now understood would allow one gram
(more or less) to store and run the entire human race at a million
subjective years per second.
Let's take a
deep breath and think about that for a moment.
One gram. The entire human race. One million years per second. That
means, using only this planetary mass for computing power, it would
be possible to support more people than the entire Universe could
support if biological humans colonized every single planet. It means
that, in a single day, a civilization could
live over 80 billion years, several times older than the age of the
Universe to date."
What can one say after that
spreadsheet below gives a small idea what subjective time can do.
