In a black hole
the amount of information
is limited by its area
and not by its volume
and it has entropy
and a temperature
even if this seems
very strange to us
but those tools
required quantum gravity
so this became a test
for superstring theory
and makes it possible
to create the concept
of holographic universe
so now you know
that it’s possible
to achieve aims
even if they seemed
rather impossible
at first glance.
