If i were to stand jupiter now with a telescope would i see life on earth 30 years ago? and if so : 1. if someone at that time was using a telescope and aiming at my exact position, could he see me looking at him? Also, if i was travelling faster than the speed of light and i looked back could i see the past by nanoseconds (etc), could i interact with the past through this method?

Thanks for the replies, just a quick question, about magnet shocks, could anyone explain futher? What liquid is used and the phsyics behind it.

Does it not just dissapate in its surrounding environment?

Hello there im currently doing a project which involves Magnetic Suspension, since i have limited experience and little knowledge on this idea, i'd like to ask some questions which can come up in my Project Specification. My intention is to replace who torsion system of a car (torsion bars, springs etc) and replace it with Magnetic Suspension. I have to consider different variables that can change in magnetism i.e the strength of a magnet or distance between each magnet. Im about to ask some questions, now that you know what im doing i'd be grateful if you can return your answers with solutions. 1. Can i create torque (rotary force) using magnetism? 2. Can i produce enough magnetism to absorb a shock load during impact of a speed bump? 3. Which other factors can i bring up to question.
