Just as Einstein banished the ether as a medium for electromagnetism
we must now complete his work by banishing space-time as a medium for
string theory. The result will be a model in which space-time is
recovered as a result of the relationship between interacting strings.

If this is correct, then space-time can only exist when information
about interactions exist. In the case of electromagnetic interactions
we have no information about these interactions at or within an event
horizon.
Therefore, it seems to me that we should be able to predict that
measurements using electromagnetic waves of the event horizons surface
will lead to non-measurements due to the lack of information coming
back and thus should mean space-time doesn't exist there.
This prediction may be falsified by winding up with a non-zero
measurement of the surface area of an event horizon using
electromagnetic waves as the measuring device.
Of course Hawking radiation predictions there are em interactions with
a blackhole, but this is only calculated if we assume there is a
non-zero surface area to the event horizon. As GR, which makes defines
the surface area, is a model of gravity, its clear that the prediction
speaks about the space-time created by gravitational interactions and
not em interactions, and thus, we should not blindly assume that the
prediction will hold for different types of interactions.
Has Dr. Gibb's reasoning been followed up to make predictions along
these lines in any existing research? Please let me know.
Thanks,
Mike
