Can a Living Creature Be as Big as a Galaxy?
This article does not take into account quantum phenomenon. It's possible that instead of being limited by the speed of light transmissions, such a system uses quantum phenomenon for communication. Which then would make the whole argument that this article makes invalid. It's based on the premise that life would be based on the same sort of physics as life on Earth... which does not make sense as such life if it exists would evolve using a different set of rules which would include things such as limits on speed of light transmission in such large systems... so it would've learned to exploit quantum phenomenon for transmission.<p>edit:<p>Superluminal, or faster than light, communication is said not to work because it allows information to be sent into the past. There is however non-locality which is not the same thing. Sorry not an expert on this, but this seems to apply to the exact discussion.<p><a href="https://en.wikipedia.org/wiki/Bell%27s_theorem#Importance_of_the_theorem" rel="nofollow">https://en.wikipedia.org/wiki/Bell%27s_theorem#Importance_of...</a>
