Space travel has always hit a wall with slow speeds and massive fuel needs. Gravitic propulsion systems offer a game-changing solution by using gravity itself as a driving force. This blog breaks down 10 major advances in gravity-based space tech, from T. Townsend Brown's early work to today's cutting-edge research at aerospace labs. Ready to explore how we might zip through space without burning tons of rocket fuel? Scientists started exploring gravitic propulsion back in the 1920s through wild experiments with high-voltage capacitors and electromagnetic fields. T. Townsend Brown's work at the Gravity Research Foundation sparked major interest when he...

An international team of scientists has demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology. The researchers found they could record information using only heat - a previously unimaginable scenario. They believe this discovery will not only make future magnetic recording devices faster, but more energy-efficient too. The results of the research, which was led by the University of York's Department of Physics, are reported in the February edition of Nature Communications. York physicist Thomas Ostler said: "Instead of using a magnetic field to...

December 23, 2009: The solar system is passing through an interstellar cloud that physics says should not exist. In the Dec. 24th issue of Nature, a team of scientists reveal how NASA's Voyager spacecraft have solved the mystery. "Using data from Voyager, we have discovered a strong magnetic field just outside the solar system," explains lead author Merav Opher, a NASA Heliophysics Guest Investigator from George Mason University. "This magnetic field holds the interstellar cloud together and solves the long-standing puzzle of how it can exist at all." The discovery has implications for the future when the solar system will...
