For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise ...

A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that theorists need to revise the “standard model” that ...

A cosmic measurement technique independent of all others adds strong evidence pointing to a problem with the current theoretical model describing the composition and evolution of the Universe. A new ...

This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact ...

Pupillary distance helps center your eyeglasses prescription. Your eyeglasses provider normally measures it for you, but you won’t find it on your prescription. If you order glasses online, you’ll ...

Physicists have improved the accuracy of a technique that uses variable stars to measure distances in the universe, providing a new figure for its expansion rate. When you purchase through links on ...
