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.

For the third time this winter, temperatures in the Arctic are forecast to rise to near freezing, this time due to a massive storm that is brewing in the North Atlantic. The continued dumping of warm, moist air into the Arctic, along with the overall rise of global temperatures and a warm Arctic winter, is hampering the region’s ability to generate new sea ice cover, already at a record low since the season started last September.

We’re all familiar with the concept of early spaceflight experiments that sent animals into space, including fruit flies, various rodents, all the way up through the quintessential space-monkey. These high-flying menageries were sent aloft to study the effects of travel into space on biological organisms, as no-one at the time knew what would happen to a human being if they were sent to that high an altitude.

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.
