Hello! My name is Alexandru, i am from Romania student at Mechanics University. I am working on a project and i also try to confirm some theory'es. I recently developed build and test a mechanism using the inertial propulsion principle. It is working but keep it in test stage. Now the advantage of this mechanism is that the acceleration is constant so its only a mater of time until this engine would reach speed of light. What would happen when it reaches the speed of light? I thinked of mounting a laptop whit wireless technology incorporated and programed to connect automatically at any free wireless access point. Is it posible that this machine when reach the speed of light to act as light do? This machine let's say will weigh's 10 Kg. and Einstein's theory say when a body reaches speed of light his mass and gravity will get infinite values and some physicists say this machine will implode in itself because of this big forces... My question: how to implode? I mean when gravity, magnetism and the mass of a body becomes infinite... what is this mean? When you travel from A to B in no time... Einstein sayd time is 0 for a body when it reaches the speed of light... am i wrong? Maybe there is someone who know's: How manny photons exist in this universe? I will appreciate all comments, discussion, explanations and answers... anything u have in mind. Thank you very much!
