Linear motors or rocket engines will be used to launch it when it departs from the moon or Mars. Each car of the train will be separated at the stations and be transported in hexagon capsules when traveling between the planets to avoid being exposed to cosmic rays. “As the idea of livin...
The high speed for the wind was estimated from a spectrum made by Chandra in 2011. A spectrum is a plot that shows how intense X-rays are at different energies. Molecules emit and absorb distinct features in spectra, which allow scientists to monitor them and their behavior. A Chandra spect...
The tank was placed deep in an old mine in South Dakota to shield it from cosmic rays. The results were surprising: the experiment detected only about one-third the neutrinos expected based on models of nuclear fusion in the Sun. Later experiments conducted elsewhere also found far fewer ...
