<div><span style="font-size: large;">Dear Arturo and FIS Colleagues,</span></div>
<div><span style="font-size: large;">Let me remember that:</span></div>
<div><span style="font-size: large;">The basic misunderstanding that non-living objects could "exchange information" leads to many principal theoretical as well as psychological faults. </span></div>
<div><span style="font-size: large;">For instance, photon could exchange only energy and/or reflections !</span></div>

<div>Dear <span style="color: #000000;">Lars-Göran, </span></div>
<div><span style="color: #000000;">I prefer to use asap my second FIS bullet, therefore it will be my last FIS mail for the next days. </span></div>

<div><span style="color: #000000;">First of all, in special relativity, a</span>n observer is NOT by definition a material object that can receive and store incoming energy from other objects. <span style="color: #000000;"><br /></span>
<div>In special relativity, an observer is a frame of reference from which a set of objects or events are being measured. Speaking of an observer is not specifically hypothesizing an individual person who is experiencing events, but rather it is a particular mathematical context which objects and events are to be evaluated from. The effects of special relativity occur whether or not there is a "material object that can recieve and store incoming energy from other objects" within the inertial reference frame to witness them.</div>
<div> </div>
Furthermore, take a photon (traveling at speed light) that crosses a cosmic zone close to the sun. The photon "detects" (and therefore can interact with) a huge sun surface (because of its high speed), while we humans on the Earth "detect" (and can interact with) a much smaller sun surface.</div>
<div>Therefore, the photon may exchange more information with the sun than the humans on the Earth: both the photon and the humans interact with the same sun, but they "detect" different surfaces, and therefore they may exchange with the sun a different information content. </div>
<div>If we also take into account that the photon detects an almost infinite, fixed time, this means once again that it can exchange much more information with the sun than we humans can.</div>
<div> </div>
<div> </div>
<div>In sum, once again, information does not seem to be a physical quantity, rather just a very subjective measure, depending on the speed and of the time of the "observer". </div>

<div>Dear Fisers,</div>
<div>a big doubt...</div>
<div> </div>
<div>We know that the information of a 3D black hole is proportional to its 2D horizon, according to the Bekenstein-Hawking equations.</div>
<div> </div>
<div>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.</div>
<div>Therefore, he detects more information from the black hole than an observer at rest, who sees a smaller horizon...</div>
</div>

An observer is by definition a material object that can recieve and store incoming energy from other objects. Since it requires infinite energy to accelerate even a slighest object to the velocity of light, no observer can travel at the speed of light. That means that your thought experiment is based in inconsistent assumptions and no vaild conclusions from them can be drawn.</div>
