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.

Like Sci-fi show, like StarTrek.
Often a laundry list of technological dreams. Food replicators, holodecks, and transporters?.

Yes to all of the above. But all item is far away at the top of wishlist is an engine capable of cutting down travel times between stars from millions of years to mere minutes. For the USS Enterprise, that means a warp engine, but scientists back on 21st century Earth are working out ways to travel to the nearest star system—Alpha Centauri—with technology that’s a bit more within our grasp.


The most prominent of these enterprises (pun intended), is a project known as Breakthrough Starshot, which aims to use lasers to propel a solar sail carrying an ultralight payload (around a few grams) for 0.1 astronomical units (AU) of its 277,000 AU journey. Hope is to reach speeds of 100 million miles per hour—roughly 20% the speed of light. That means miniature probe could reach Earth’s nearest star, located some 4.25 light-years away, in just 20 years...
