(PhysOrg.com) -- One of the biggest unsolved problems in astrophysics is that galaxies and galaxy clusters rotate faster than expected, given the amount of existing baryonic (normal) matter. The fast orbits require a larger ...
(Phys.org) —The quintessential feature of a black hole is its "point of no return," or what is more technically called its event horizon. When anything—a star, a particle, or wayward human—crosses this horizon, the ...
With current space travel limited to just a few robotic probes visiting nearby planets, how realistic is it to think about reaching the nearest stars? For the short term, not very – especially when we speak of manned missions. ...
A small team of biostatisticians and engineers from Princeton, Harvard, and MIT, has found via survey, that Chinese scientists working in the U.S. no longer feel welcome in the country.
(PhysOrg.com) -- With its complete lack of atoms, a vacuum is often considered to be the best known insulator. For this reason, vacuums are regularly used to reduce heat transfer, such as in the lining of a thermos to keep ...
A team of researchers with the Ocean Cleanup project and Wageningen University, both in the Netherlands, has found via sampling and testing that more than 90% of the identifiable trash swirling around in the North Pacific ...
Scientists from Spectrolab, Inc., a subsidiary of Boeing, have recently published their research on the fabrication of solar cells that surpass the 40% efficiency milestone—the highest efficiency achieved for any photovoltaic ...
(PhysOrg.com) -- Ever wish you could you power your home's electrical appliances with the energy you generate on your exercise bike? A new concept called an "inlet outlet" could allow homeowners to put power from kinetic ...
(PhysOrg.com) -- A prototype robot spy "ornithopter," the Nano-Hummingbird, has successfully completed flight trials in California. Developed by the company AeroVironment Inc., the miniature spybot looks like a hummingbird ...
Thane Heins knows the track record of inventors that claim to make breakthroughs in power generation methods, especially when they claim to defy the second law of thermodynamics. Every so often, a (usually untrained) scientist ...
