Future of Under One Hour Travel Between Major World Cities

SpaceX will bring point to point travel between major world cities starting near the end of the 2020s if they can increase the safety. It will more likely become significant around 2035-2045. The first spaceports would be in New York, London, San Francisco, Los Angeles, Tokyo, Dubai, Singapore, Shanghai and Beijing. This would be followed …

DARPA aims for personal mobile ultra low frequency radio for transmitting devices to communicate through water and soil instead of 2000 acre transmission complexes using megawatts of power

A DARPA project could enable radio to be transmitted through water and rock. Radio frequency signals hit veritable and literal walls when they encounter materials like water, soil, and stone, which can block or otherwise ruin those radio signals. This is why scuba buddies rely on sign language and there are radio-dead zones inside tunnels …

If our space telescopes imaged an alien megastructure then what would we see ?

Researchers have noted that planet-sized (or larger) artificial structures could be discovered with Kepler as they transit their host star. Jason Wright and other astronomers present a general discussion of transiting megastructures, and enumerate ten potential ways their anomalous silhouettes, orbits, and transmission properties would distinguish them from exoplanets. We also enumerate the natural sources …
