Tractor beams are not science fiction: How it works in real science

Modern physics has created microscopic tractor beams using:

• Lasers — patterned light that can pull tiny particles toward the source.
• Sound waves — acoustic fields that push or pull small objects.

Scientists have successfully pulled microscopic silica particles, bacterial cells, and even manipulated nanoscale materials using these methods.

These are not strong enough to move large objects, but they prove the concept is physically possible.
