A new documentary by NOVA follows recent experiments which aim to verify Bell's theorem at the Cosmic scale in order to address possible loopholes in Bell's theory [1,2]. It appears from the results of this experiment that quantum entanglement is a reality of our Universe and that Einstein's criticism of this idea (which he called "spooky action at a distance") might not be correct. Einstein, along with Podolsky and Rosen, wrote a well known paper which proposed the so called EPR paradox according to which quantum mechanics, due to the presence of hidden variables, is incomplete. Bell's theorem, which was verified experimentally, disfavored the hidden variable interpretation and appear to indicate that quantum entanglement is a reality of our Universe.
I also believe that quantum entanglement might take us to a world beyond Einsteins theories of space-time. It appears to indicate that there are other modes of information transfer in the Universe. As I always say, light is a very defective way to transfer information because it is limited in speed, changes speed in different materials, bends in strong gravitational fields and also our brain intrinsically assumes that light travels in a straight line. There has to be a better mode of information transfer in the Universe. Time will tell whether we will be able to harness this interesting phenomenon to build quantum computers that lay the foundations of future technologies.
It also appears that there are clear indications from such experiments that we need to start thinking of ideas beyond Einstein's theory of space time. The present academic atmosphere, however, is very conservative when it comes to Einstein's theories. You can never question Einstein or you are treated as a science 'heretic'. In the documentary Sean Carroll actually says something very interesting that reflects the ongoing academic culture:
" It's a very strange thing that ever since the 1930s the idea of sitting and thinking hard about the foundations of quantum mechanics has been disreputable among professional physicists. When people tried to do that they were kicked out of physics departments"It also appears that there are clear indications from such experiments that we need to start thinking of ideas beyond Einstein's theory of space time.

Similarly, thinking about Einsteins theories from a different perspective can also mean that you have to give up your career. This is one of the reasons progress in science has been crawling in the last few decades.
