To determine if the universe will expand forever, coast to a stop or collapse on itself, astronomers must decide which of two opposing forces will win a cosmic tug-of-war. One of these forces is the bang part of the big bang— the explosion that catapulted the universe outward in all ...
The universe began with a gigantic explosion, called the Big Bang. About 14 to 15 billion years ago, something about the size of an atom suddenly started expanding dramatically. Out near the edge of the universe, there is still Cosmic Microwave Background, which is the heat left over from ...
The entire universe has faint cosmic microwave background radiation -- something scientists connect to the Big Bang Theory. Infrared: Infrared lies between the visible and invisible portions of the EM spectrum. Your remote control uses infrared light to change the channel. We feel infrared radiation...

Microwave-pulsing devices also can be used to "fry" the electronics of IEDs. Another device called LIBS (laser-induced breakdown spectroscopy) uses lasers to detect IED explosives within a 100-foot (30-meter) radius. Alternatively, you might not need a soldier to deal with a suspected IED ...
The more nodes, the further the connection spreads, creating a wireless "cloud of connectivity" that can serve a large office or a city of millions. The Mesh System Advantage If you only need to provide internet access to a small area, you aren't likely to see a big difference between...
