Default A Revised Planck Scale?

No, it is in conflict with the fact that I can stand up if
what you say of the proton is true.



Your comments on whether or not you can stand up bring to mind
something relevant.

Long ago, Galileo proposed that the Earth spins on its axis once per
day. Many of the scholars at that time ridiculed this idea and claimed
it was simple to disprove. If the Earth had such a motion, they showed
that any point on the Earth's surface would be moving at something on
the order of 1,000 miles per hour, *and in a circle*. The scholars,
tut-tutting appropriately, argued that no one would be able to stand up
and objects might even be thrown off the Earth. Aristotle and physics
had *completely proved* that Galileo's idea had to be wrong, and was,
in fact, absurdly wrong.

Well, now we know that Galleo was right and the learned scholars were
the ones who were in error. What do we learn from this? Two things: (1)
physics is *always* incomplete, and (2) even common sense applications
of physics can lead to gross errors of judgement. Lord Kelvin, for
example, once claimed that Darwinian Evolution was falsified because
the laws of physics demanded that the Sun had shone for less than one
million years! So it goes. Same as it ever was.

Discrete self-similar spacetimes behave differently than continuous
spacetimes.
