The change is with respect toDennisN said:I hope you are aware that the name change is not, and never will be, universal:
If there is life on any planet in the Alpha Centauri/Proxima system, and they are able to observe computer monitors of PF members, the Alpha aliens won't notice the name change until about 4 years has passed.
Furthermore, there is a huge volume of space which the light from the monitors of PF members have not reached yet, which means aliens in this region are unaware that Physics Forums exists (cosmological horizons). I leave it to the interested readers to calculate how big the observational "light sphere" of Physics Forums is in space, but you may have to ask @Greg Bernhardt when the first version of the forum was put online, since this information is needed to perform the calculation.
And why not end this post even more tragically? There is a huge region of space in which aliens never will know Physics Forums exists. Since the Universe is expanding, the light from the monitors of PF members will never reach that region (particle horizons).
