It's pretty easy to dispense of it as a flight of fancy.
"intents and purposes" btw
I'm sorry, but that is patently absurd.
The diameter of our Hubble Volume is probably around 91 billion light-years, and its mass is roughly 3 x 1055 g. Most of this is not observed by any organisms. The idea that we're having an effect on the entire universe, just by being conscious, doesn't make sense.
Ethics 101 is thataway ---->
By the way, nothing about what you're suggesting lends itself to any specific theory of ethics. E.g. if we are all Blissed Out Cosmic Consciousness, then pain is just some other sensation, and why shouldn't we run around and cause each other to suffer? It's all cosmic, dude.
