Primordial weirdness: Did the early universe have one dimension? Scientists outline test for theory That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. They suggested that the early universe -- which exploded from a single point and was very, very small at first -- was one-dimensional (like a straight line) before expanding to include two dimensions (like a plane) and then three (like the world in which we live today). The theory, if valid, would address important problems in particle physics.
Universe Sandbox is an interactive space simulator for Windows based PCs. Unlike most astronomy software that just shows you what the sky looks like or where the planets are, Universe Sandbox is a powerful gravity simulator. You can add another star to our solar system and watch it rip the planets from their orbits. The free forever version allows you to explore and discover any simulation. Optionally you can upgrade to to the premium version for unlimited control. Watch the Video
Description 3D simulation of the Solar System and night sky in real time - the Sun, planets, dwarf planets, comets, stars and constellations. - Heliocentric view with real-time positions of planets and planetary orbits - Schematic and realistic sizes of the planets and distances between them - Movement of the planets in time to see how they move in relation to each other - Virtual Orrery - Planetary exploration with info texts and additional views such as structure - Dwarf planets (Pluto, Ceres, Haumea, Makemake. Eris) and their orbits - Comets (Siding Spring, Lovejoy 2013, Lovejoy 2011, Panstarrs, ISON, Halley) - positions and trajectories - Stars and constellation of the night sky as viewed from a given location - Changes in the night sky during night, month and year - Searching of the stars and constellation, ecliptic line, grid lines and more

Graphene Will Change the Way We Live | Dr. Kaku's Universe The theory behind the substance graphene was first explored by theoretical physicist Philip Wallace in 1947 as kind of a starting point when he was doing research trying to understand the electronic properties of more complex, 3D graphite. although the name graphene wasn't actually coined until 40 years later, where it was used to describe single sheets of graphite. In other words, it's the name given to a flat monolayer of carbon atoms that are tightly packed into a 2D honeycomb lattice; like a molecular chicken-wire that is one atom thick. It's essentially the basic building block for graphitic materials of all other dimensionalities; it's a stepping stone to building bigger things.

SiGNa Chemistry Inc. is launching a hydrogen-producing cartridge, the mobile-H2™, that will work with a portable, pocket-sized fuel cell charger to provide instant power for cell phones and other mobile devices. You simply add water to the cartridge, and the device will charge depleted batteries on the go. For further convenience, any water will do (even waste water). Unlike solar battery chargers, you don’t need to worry about getting enough sunlight. Canister lets you add water (or bodily fluids) to recharge batteries

Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Does the term "universe" refer to space, or to the matter in it, or to both?
