Space Travel

I can imagine the most beautiful thing is trying to comprehend the vast sizes and distances away from Milky Way and the spaces between our star systems with the distances between galaxies being so much greater many times over. Imagine a time of no noise, no pollution, and green energy security forever, no need for roads, shoes, tires. Everything levitates using just a small amount of electric energy to compensate for ohmic losses. Works everywhere, including the vacuum of space, and only need electric energy, converting it to kinetic through magnetic force; the fantastic fact is that this invention was possible in Tesla times. Can a magnetic field charge plasma as it is exhausted through a turbine, jet combination allowing for more powerful propulsion? What is limiting us from shielding the attracting forces of gravity? What are electromagnetic drives? What if we can travel within laser beams?
