Until now, no technology was known that would be able to give rocket exhaust at relativistic speed and a high enough momentum for relativistic travel. Here, a useful method for relativistic ...

IT is well known that when positrons are annihilated, -rays with quantum energy of about 500 ekv. are emitted. This seems to prove that annihilation occurs with a loosely bound electron as a partner ...

When a photon interacts with a material, an interaction occurs that causes its atoms to change their quantum state (a description of the physical properties of nature at the atomic level). The ...
