A while back first potential hints arose in scientific circles that our universe is not a 4 dimensional space-time manifold but rather a hologram on a 2 dimensional surface, like an infinite sheet of paper. This would mean our most fundamental concepts like space and time would be revealed as nothing more than an illusion. Astonishing. 

However it seems like mainstream media as well as the public have nothing to say about it. No philosophical discussions, no attempts at rethinking our place in the world. No one really cares. If a spaceship landed at Champs-Élysées with Gautama Siddharta, Jesus and Mohamed coming out proclaiming they're ancient aliens from the Orion constellation which came to revisit Earth, this wouldn't be half as astounding as the Hologram theory. I can't overstate enough how profound this insight into the potential nature of our reality is. Despite that most people would still rather read about Dennis Rodman visiting Kim Jong Un.
