Scientists Say They’ve Tested a Way to Get to Alpha Centauri in Just 20 Years
Researchers at Texas A&M University have demonstrated a laser‑propelled micro‑device called a metajet that can move in three dimensions without physical contact. The metajet’s metasurface pattern redirects incoming light, converting photon momentum into thrust, a principle the team says can be scaled by increasing laser power. If scaled to spacecraft size, the technology could enable a probe to reach Alpha Centauri in roughly 20 years, a dramatic reduction from millennia‑long generation ships. The next milestone is testing the system in microgravity to prove its viability for interstellar missions.
