New Invisibility Cloak is Extremely Thin


Invisibility is not unreachable anymore. What we have seen in movies like the invisible Man has become more realistic over the past years. A new study has taken another step in making invisibility...

Our Universe Might Be a Hologram Say Scientists


Are we living in a two dimensional world and just perceive the third dimension? An international group of scientists has worked on a theoretical mathematical model that proofs that the holographic...

Researchers create space-time crystal schematic, still won’t undo those ill-advised high school photos

Researchers create spacetime crystal schematic, still won't undo those illadvised high school photosThink your cute little Minecraft schematics are the bomb? Well, a group of international researchers sees your quaint, little 3D masterpiece and raises you the blueprint for a 4D space-time crystal. Building on an idea floated earlier this year by theoretical physics guru and Nobel Laureate Frank Wilczek of MIT, a team led by UC Berkeley researcher Tongcang Li has created a schematic for a crystal with a fourth dimension -- movement in time. The resulting space-time crystal is being described as something akin to an infinitely running clock that does not require any additional energy once it starts going. The researchers also claim that the crystal can be built in just a few years -- provided that the necessary funding is available to the team that decides to take on the project, of course. Unfortunately, the crystal is still a long way from the Mr. Fusion-powered, time-traveling DeLorean that we truly desire. In the meantime, brainy types can feel free to click on the source link for more nuggets of wisdom about the research.

Vanishing neutrons could be travelling to a parallel universe

Vanishing neutrons could be travelling to parallel universes

Time to break out your theoretical physics cap for a moment. A new idea about the cause of neutron loss (a phenomena in which neutrons seem to momentarily disappear), is pushing the boundaries of easy to conceptualize science. Zurab Berezhiani and Fabrizio Nesti of Italy's University of l'Aquila have suggested that the particles could briefly be visiting parallel universes before returning. Experiments have shown that the rate of loss is dependent on the direction and strength of an applied magnetic field -- an anomaly that doesn't jibe with current physics. If a parallel universe existed consisting of so-called "mirror particles," however, the neutrons could temporarily swap places with its invisible twin before returning to its rightful place in this world. More experimentation is needed, but if the predictions of Berezhiani and Nesti are correct, it could indicate that we're surrounded by mirror particles in a parallel universe -- a potential culprit for the mystery of dark matter.
