Dear Fisers, a big doubt...
We know that the information of a 3D black hole is proportional to its 2D 
horizon, according to the Bekenstein-Hawking equations.
However, an hypotetical observer traveling at light speed (who watches a black 
hole at rest) detects a very large black hole horizon, due to Einstein's 
equations.Therefore, he detects more information from the black hole than an 
observer at rest, who sees a smaller horizon...
In sum, information does not seem to be a physical quantity, rather just a very 
subjective measure...
