Beam me to the stars: Scientists propose wild new interstellar travel tech

Researchers propose a new propulsion method that could make covering the vast distances required for interstellar missions feasible within a human lifetime.

The fundamental challenge in reaching a different star system lies in figuring out how to generate and transfer enough energy to a spacecraft both efficiently and affordably.

One such solution that was recently proposed uses electron beams accelerated to near the speed of light to propel spacecraft.

Team suggests placing a "beam-generating spacecraft" close to the sun, where intense sunlight could provide the power needed for the beam.

This would enable it to reach Alpha Centauri in just 40 years , a significant improvement over the current 70,000 years it would take.

The ability to beam power over long distances has wide-ranging implications.
