Whenever I find myself harboring a constantly nagging thought, I know I will eventually have to get busy and find a way to put it to rest. When I read EDN’s Design Ideas, I look for the range of ...

Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

June 29 (UPI) --Shock waves from giant black holes merging at the heart of distant galaxies recently detected by scientists may be direct evidence of black holes distorting space-time, according to ...

A calm-water setting was measured for reference, in addition to ten different scenarios of waves. Those differed in their wave amplitude, wavelength, and wave frequency. Per their measurement, the ...
