Physicists with MIT and the University of Vienna have conducted an experiment that pretty much proves that the phenomenon of quantum entanglement is real, and not the effect of a "loophole" that could be explained by classical physics. The experiments that were used in closing this loophole involved a combination of Earth-bound telescopes, 30,000 entangled pairs of entangled photons, and starlight nearly as old as the universe itself.

Amongst the multitude of mysteries that the universe holds, the answers to what might be the most elusive ones are whether or not is finite or infinite, both in terms of its physical breadth, but also its age: is there a beginning and an end? And for that matter, if it is finite in its physical dimensions, are there other universes that are adjacent to our own? As Einstein famously put it, "Only two things are infinite, the universe and human stupidity, and I’m not sure about the former."

However, Einstein’s tongue-in-cheek quip about the universe have been addressed by two new studies that offer new insight into both the possible physical dimensions of the universe, and the possibility that it may indeed be ageless.

A recent study has added new evidence to the controversial theory that the three-dimensional nature of our universe is actually a holographic projection from a two-dimensional plane. The holographic principle, as it is known, isn’t widely accepted by the scientific community, as it upends the classical model of physics. However, where the classical model has failed to reconcile quantum mechanics with the macroscopic world, the holographic principle does a much better job of doing so, and this latest study has also offered a real-world demonstration that the principle may be valid.

A new theory that has been proposed may deflate the commonly-accepted origin of the universe, namely the Big Bang theory, in that it never happened at all. This new theory also implies that the universe is infinite in age, and may continue to exist forever.

As is widely known, the Big Bang theory posits that all of the energy (and thus matter) in the universe was once compressed into an extremely dense singularity, of which exploded 13.8 billion years ago. This idea of this singularity stems from equations derived from Einstein’s theory of general relativity, that shows that all matter occupied one point in space.
