1) Traveling from one star to another is currently impossible to achieve within a human lifetime. But some projects are designing ways to propel payloads to the nearest star system (Alpha Centauri) using beams of electrons.

2) A new proposal uses an electron beam fired from a stable platform near the Sun, which could push a 1,000 kg spacecraft for up to 100 AU (100 times the distance from the Sun to Earth).

3) Although filled with yet-to-be-discovered materials and concepts, this idea could theoretically propel a probe to Alpha Centauri in just about 20 to 40 years.
