It's only 2015, I think it's a little ridiculous to make far sweeping conclusions about whole realms of science supposedly not working based on limited current understanding of science.
It is only 2015, and the conclusions you reach must make sense according to what is known in 2015.
And our current understanding of science is only limited in comparison to wild speculation. Those limits also happen to be the strongest point in its favor.
Scientists know very little about QM despite it being known for 80 years due to political, resource and human IQ restraints. The human knowledge in this area is not even in infancy yet.
The experiments on Quantum Entanglement have only begun to intensify in recent years. With the advent of AI and commercial interest in the field due to communication opportunities, this may change rapidly.
When you say FTL communication is impossible that is a mere speculation at best, and a remarkably short sighted and laughable one in retrospect to paradigm shifts in the history of human technology. Scientific conservatism like that is a silly and shameful attempt to signal high status, which has held back human progress many times in the past. FTL communication is a major necessity and this field needs to be explored and pushed into hard without being held back by naysayers with dubious motives.
We've known about QM for 80 years. It's given accurate predictions for all that time. What exactly do you think is limited in currnt understanding of science?
