The Holographic Universe [we might Live in!]
Are you feeling a little… flat? Well that might be because you are only in 2 dimensions. I know what you’re thinking, insane! Well first check the name of the business and second, check out the science. In fact, it may seem like a joke, but the math suggests that it could very well be true and with it could come a deeper understanding of the universe. Testing this hypothesis (which was first made in the late 90’s) has been harder to do than you might think, but that has now changed. We are officially checking to see if our universe is a hologram!
Neutrinos have a weight problem

There have been some unfortunate problems with the Standard Model of Cosmology. These problems came from the fact that the neutrinos mass was never accurately measured. Thanks to some new observations, we now have managed to [hopefully] find the mass of a neutrino for the first time.
The study I am referring to was completed by Richard Battye and Adam Moss. It was recently published in Physical Review Letters. Using the Planck satellite, which was launched in 2009, scientists have been able to observe directional dependent aspects of the Cosmic Microwave Background [CMB].
